Hiring developers is hard. Hiring remote developers is harder.
You can’t walk over to their desk and see what they’re working on. You can’t judge their skills by watching them code in person. You’re trusting someone you’ve never met to build critical parts of your product.
Most companies handle this by throwing a coding challenge at candidates and hoping for the best. That’s better than nothing, but it misses a lot.
This guide walks you through a complete technical vetting process for remote developers. Use this and you’ll know if someone can actually do the work before you hire them.
Why Remote Developer Hiring is Different
Before we get into the how, let’s talk about why remote makes sense for SEO roles specifically.
When you hire a developer to work in your office, you get signals beyond their technical skills:
- How they interact with the team during lunch
- Whether they ask good questions in meetings
- How they handle frustration when code doesn’t work
- Their energy and work ethic over time
Remote hiring removes all of these signals. You’re making a decision based on:
- What they tell you in interviews
- Code they show you (which might not be theirs)
- References (which are often cherry-picked)
That’s why technical vetting matters more for remote roles. You need objective evidence that someone can code, not just their word.
The Four Types of Remote Developers
Before we get into vetting, understand what type of developer you actually need.
Here’s what to evaluate:
1. Full-Stack Developers
What they do: Build both frontend (what users see) and backend (server, database, logic)
When you need them:
- Early-stage startups (need to build everything)
- Small teams (can’t afford specialists yet)
- MVPs and prototypes
Key skills: JavaScript, React or Vue, Node.js or Python/Django, SQL databases, API design
Cost: $1,500-$3,500/month for mid-level remote
2. Frontend Developers
What they do: Build user interfaces, handle client-side logic, optimize user experience
When you need them:
- UI-heavy products (dashboards, apps with complex interfaces)
- You already have backend covered
- Design implementation is critical
Key skills: JavaScript/TypeScript, React/Vue/Angular, CSS/Tailwind, state management, responsive design
Cost: $1,200-$3,000/month for mid-level remote
3. Backend Developers
What they do: Build APIs, handle business logic, manage databases, integrate third-party services
When you need them:
- Data-heavy applications
- Complex business logic
- Scaling infrastructure
Key skills: Python/Node.js/Java/Go, database design, API architecture, authentication, testing
Cost: $1,500-$3,500/month for mid-level remote
4. Mobile Developers
What they do: Build iOS, Android, or cross-platform mobile apps
When you need them:
- Mobile-first products
- Companion apps for web products
Key skills: Swift/Kotlin or React Native/Flutter, mobile UI patterns, app store deployment, push notifications
Cost: $1,800-$4,000/month for mid-level remote
Start by figuring out which type you need. Don’t hire a full-stack developer when you specifically need someone excellent at React. Specialists are better than generalists for most mature products.
The Complete Technical Vetting Framework
Here’s the step-by-step process to vet remote developers properly.
Step 1: Portfolio Review (15 minutes per candidate)
Before you talk to anyone, review their work.
What to look for:
GitHub Profile
- Consistent commit history (not just one burst of activity)
- Clean, documented code
- Contribution to open source projects (shows they work with others)
- Recent activity (last 30 days should show commits)
Live Projects
- Working websites or apps they’ve built
- Not just screenshots, actual URLs you can visit
- Test the product (does it work? Is it fast? Is the UX good?)
Code Samples
- Ask for specific examples: “Show me a React component you’re proud of”
- Look for: readable code, proper naming, comments where needed, no obvious bugs
Red flags:
- No public code (claims it’s all private) but also no live projects to show
- Only tutorial projects (todo apps, weather apps) with no original work
- Code that looks copy-pasted from Stack Overflow with no understanding
- Years of experience claimed but GitHub shows 3 months of activity
Step 2: Technical Screening Call (30 minutes)
Don’t start with a coding challenge. Start with a conversation to see if they actually understand development.
Questions to ask:
For all developers:
“Walk me through your typical development workflow from getting a new feature request to deploying it.”
What you’re listening for: Do they have a process? Do they think about requirements, edge cases, testing, deployment? Or do they just “start coding”?
“Tell me about a technical challenge you faced recently and how you solved it.”
What you’re listening for: Can they explain technical concepts clearly? Do they problem-solve systematically? Do they learn from challenges?
“How do you decide when to build something from scratch vs. use a library?”
What you’re listening for: Do they understand trade-offs? Do they over-engineer or under-engineer?
For frontend developers:
“How do you approach performance optimization in a React application?”
Good answer mentions: Code splitting, lazy loading, memoization, virtual scrolling, image optimization
For backend developers:
“How do you design a database schema for [describe your app]?”
Good answer includes: Thinking about relationships, indexes, query patterns, future scaling
For full-stack developers:
“How do you handle authentication in a web application?”
Good answer covers: JWT vs. sessions, password hashing, HTTPS, CSRF protection, refresh tokens
Red flags:
- Can’t explain their own code or projects
- Gives textbook answers but can’t apply concepts to real scenarios
- Dismisses questions as “not important” or “I’d Google that”
- Rambles without structure (shows unclear thinking)
Step 3: Coding Challenge (2-4 hours)
Now give them actual code to write. This is where you see if they can do the work.
How to design the challenge:
Make it relevant to your actual work
Bad challenge: “Implement a binary search tree”
Good challenge: “Build a simple dashboard that fetches data from this API and displays it in a chart”
Use problems similar to what they’ll actually do on your team.
Keep it time-boxed
Don’t ask for 8 hours of work. That’s disrespectful of their time and yours.
2-4 hours is enough to see if someone can code. Pay them $100-$200 for their time if you want the best candidates to take it seriously.
Provide clear requirements
Give them:
- Specific feature to build
- Example data or API endpoints
- Success criteria (what “done” looks like)
- Tech stack to use (or let them choose)
Evaluate multiple dimensions
Don’t just check if the code runs. Look at:
- Does it meet requirements?
- Is the code readable and organized?
- Did they handle edge cases?
- How did they structure components/functions?
- Is there any testing?
Example challenges by role:
Frontend Developer: “Build a paginated table component that fetches user data from this API. Include search functionality and sorting. Use React.”
Backend Developer: “Build a REST API with 3 endpoints: create user, get user, list users with pagination. Use Node.js and PostgreSQL.”
Full-Stack Developer: “Build a simple todo app with authentication. Users should be able to create, complete, and delete todos. Use any stack you’re comfortable with.”
Red flags:
- Code that doesn’t run or has obvious bugs
- No error handling or validation
- Copy-pasted code they clearly don’t understand
- Overly complicated solutions to simple problems
- No documentation or comments
Step 4: Code Review Discussion (30 minutes)
After they submit the coding challenge, review it together on a call.
Walk through their code together: “Can you explain how this function works?”
“Why did you choose this approach?”
“What would you do differently if you had more time?”
Good candidates will:
- Explain their thinking clearly
- Acknowledge trade-offs they made
- Know exactly what their code does
- Be open to feedback and suggestions
Bad candidates will:
- Struggle to explain their own code
- Defensively reject any feedback
- Clearly don’t understand what they wrote
- Can’t answer “why” questions
Ask refactoring questions: “If we needed to add [new feature], how would you modify this code?”
“How would you make this more scalable?”
This shows if they can think beyond the immediate problem.
Step 5: System Design Question (30 minutes, for mid-level and senior only)
Skip this for junior developers. For mid-level and senior, test their architectural thinking.
Good system design questions:
“Design a URL shortener like Bitly. How would you handle storing billions of URLs and redirecting traffic?”
“Design a chat application that needs to support 10,000 concurrent users. What’s your approach?”
“Our API is getting slow as our database grows. How would you diagnose and fix performance issues?”
What you’re evaluating:
- Can they think at the system level, not just code level?
- Do they consider trade-offs (speed vs. cost vs. complexity)?
- Do they ask clarifying questions before jumping to solutions?
- Do they break big problems into smaller pieces?
You’re not looking for perfect answers. You’re looking for structured thinking and realistic understanding of constraints.
Step 6: Reference Checks (15 minutes, 2-3 references)
Talk to people they’ve actually worked with. This catches problems you can’t see in interviews.
Questions to ask references:
“What did [candidate] work on for you?”
“What were their strengths?”
“What could they improve?”
“How was their communication and reliability?”
“Would you hire them again?”
That last question is critical. If someone hesitates or says “it depends,” that’s a red flag.
Red flags from references:
- Vague answers that don’t give specific examples
- Can’t remember what the person actually did
- Damning with faint praise (“they were fine”)
- Won’t commit to hiring them again
Step 7: Trial Period (30 days)
Even with perfect vetting, you won’t know if someone is truly good until they work on your actual product.
How to structure the trial:
Give them a real project
Not busywork. An actual feature or bug fix that matters. Something that takes 2-4 weeks to complete.
Set clear expectations
- What needs to be delivered
- When it’s due
- How you’ll communicate (Slack, email, video calls)
- What “good work” looks like
Check in regularly
Don’t wait 30 days to give feedback. Weekly check-ins help you spot problems early.
Evaluate honestly
At day 30, ask yourself:
- Would I want this person working on critical features?
- Is their code quality what we need?
- Is communication smooth?
- Do they solve problems independently or need constant hand-holding?
If the answer to any of these is “no,” it’s better to part ways now than 6 months from now.
Red Flags You Can’t Ignore
Some warning signs should end the hiring process immediately:
Portfolio red flags:
- Can’t provide any code samples (“all my work is confidential”)
- Code shown doesn’t match their claimed skill level
- Takes credit for team projects without clarifying their role
- GitHub shows almost no activity despite claiming years of experience
Interview red flags:
- Can’t explain fundamental concepts for their experience level
- Blames previous employers or team members for everything
- Overly confident without backing it up with specifics
- Poor communication (you can’t understand what they’re saying)
Coding challenge red flags:
- Code clearly copied from Stack Overflow or ChatGPT without understanding
- Misses major requirements from the brief
- Takes much longer than time estimate without communicating
- Defensive when you point out bugs or issues
Reference red flags:
- Can’t provide any references (“we lost touch”)
- References are clearly friends, not past managers or clients
- References give generic positive feedback but no specifics
- References won’t vouch for technical skills
Trust your gut. If something feels off, it probably is.
Common Hiring Mistakes
Mistake 1: Skipping the technical assessment
“Their portfolio looks great, we don’t need to test them.”
Portfolios can be faked. Code can be copied. Always verify someone can actually code before hiring them.
Mistake 2: Testing the wrong skills
You need someone to build CRUD APIs but you test them on algorithms and data structures.
Test for the skills they’ll actually use on your team, not computer science theory.
Mistake 3: Hiring based on tools, not fundamentals
“They know our exact tech stack” sounds great but good developers learn new tools quickly.
Someone who deeply understands JavaScript can learn React in 2 weeks. Someone who memorized React patterns without understanding JavaScript will struggle when things break.
Hire for fundamentals. Tools can be learned.
Mistake 4: Going too junior to save money
A junior developer ($900-$1,200/month) needs significant guidance. If you don’t have time to mentor them, they’ll struggle and waste time.
A mid-level developer ($1,800-$2,500/month) can work independently and actually saves you money because they need less hand-holding.
Don’t cheap out if you need someone who can own a project.
Mistake 5: No trial period
You think the vetting process was perfect so you commit to 12 months immediately.
Always start with 30 days. It protects both sides. If it’s not working, you can part ways without drama.

Plus benefits add 25-30% on top of salary.
Remote saves you 60-75% without compromising quality.
Managing Remote Developers
Once you hire someone, here’s how to set them up for success:
Week 1: Onboarding
- Give them access to code repository, tools, documentation
- Have them set up local development environment
- Assign a small starter task (fix a bug, add a small feature)
- Schedule daily check-ins this week
Week 2-4: Ramping up
- Increase complexity of tasks gradually
- Weekly 1-on-1s to answer questions and provide feedback
- Start including them in team meetings
- Monitor code quality through pull requests
Month 2+: Full integration
- They should be contributing at full capacity
- Shift to bi-weekly 1-on-1s
- Give them ownership of features or modules
- Treat them like any other team member
Communication best practices:
- Overlap at least 4 hours with your business hours
- Daily standups (async in Slack or sync video call)
- Written documentation for all major decisions
- Over-communicate early, can reduce frequency later
Final Thoughts
Hiring remote developers requires more upfront vetting than local hires, but the payoff is worth it.
You get access to global talent at 60-75% cost savings compared to local hiring. You just need a systematic process to separate good developers from people who interview well.
Use this checklist:
- Portfolio review (verify real work)
- Technical screening call (can they explain concepts?)
- Coding challenge (can they actually code?)
- Code review discussion (do they understand their own code?)
- System design (can they think architecturally?)
- Reference checks (do past employers vouch for them?)
- Trial period (can they deliver in your actual environment?)
Skip any of these steps and you risk a bad hire. Follow all of them and you’ll find great developers who deliver.
