Full-Stack Developer job description
A Full-Stack Developer builds both the screens users see and the server code behind them. A small or growing business needs one to ship whole features without waiting for several specialists.
Why the role exists
The Full-Stack Developer carries a feature from database to screen. In Indian startups and small product teams, where one or two engineers may cover the whole product, this person keeps work moving. They suit teams that value speed and breadth, and they know when a problem needs a specialist.
What the person does
- Build complete features, from the database table and API to the screen the customer uses.
- Choose simple designs that a small team can maintain, and write down the reasons in short notes.
- Set up and update the app's database, authentication and file storage.
- Fix bugs wherever they appear, whether in the browser, the API or the data.
- Deploy releases to the cloud and check that the new version works for real users.
- Write tests for the most important flows so changes do not break sign-up, payment or reports.
- Talk to the product owner or founder to trim a request down to the smallest useful version.
- Keep dependencies updated and clear small technical debts between feature releases.
Skills and tools
- A frontend framework such as React or Vue together with HTML, CSS and TypeScript
- A backend stack such as Node.js, Django, Laravel or Spring Boot
- SQL and one NoSQL store, with sensible schema design
- Authentication, sessions and role-based access for web apps
- Deploying to AWS, Azure, GCP or simpler hosts with Docker
- Git, pull requests and basic continuous integration
- Debugging across the browser, network and server
- Prioritising work and explaining trade-offs to non-technical founders
Education and experience
Preferred, never a bar: equivalent experience counts.
- Preferred: a degree in computer science, IT or a related field, or equivalent experience.
- Preferred: at least one complete product or major feature built and released by the candidate.
- Candidates from non-traditional paths are welcome when they can show working projects.
- Preferred: comfort working in a small team where roles overlap and priorities change.
How the work is judged
- Features delivered end to end and working properly in front of real users.
- Defects that reach customers and the speed at which they are traced and corrected.
- Simplicity and maintainability of the code, judged by how easily others can extend it.
- Quality of communication with founders, designers and the wider team about scope and delays.
- Learning shown by taking on unfamiliar parts of the stack when the product needs them.
Where the role can lead
- Senior Full-Stack Developer or Tech Lead, owning a product area and its quality.
- Specialising in backend, frontend or cloud work as the team grows.
- Engineering Manager or founding engineer, shaping the team and the technical direction.
Interview questions to ask
Ask every candidate the same questions in the same order and score them against written anchors, so the decision rests on the work and not the impression.
- Take a feature you built from screen to database. Where did you spend the most time and why?
- How would you build a simple booking page, and what would you leave out of the first version?
- A customer says their data looks wrong on screen. How do you work out whether the fault is in the UI, the API or the database?
- Which side of the stack do you know less well, and how are you improving it?
- How do you decide when to use a ready-made service rather than build your own?
- Describe a release that went wrong. What did you do in the first hour?
Hiring tips for this role
- Test breadth with one small task that touches both screen and data. Strong full-stack people are usually good at one side and sound on the other.
- Beware of resumes that list every framework. Ask for the most complex thing built alone and ask them to draw how it worked.
- Clarify what you really need. If one side of the product is heavy, hire for that depth first instead of expecting equal strength everywhere.
- Look for ownership. Ask how they handled a problem nobody assigned to them, since small teams rely on that habit.
Questions about hiring a full-stack developer
Early-stage teams and small products often gain from full-stack people because one person can finish a feature alone. As traffic and team size grow, separate frontend and backend roles help depth and speed.
For a first version, often yes. Over time, security, performance and design work grow beyond one person. Plan to add specialists or advice as your customers and data grow.
