How to hire your first developer for a startup

Your first startup developer should be an experienced full-stack engineer who can make technical decisions alone, not a narrow specialist who needs a manager. If the founder is not technical, bring in a technical adviser for hiring, and build the process around a paid take-home task close to real work rather than theory questions.

Below: who to look for, how to assess a candidate without a technical background, and which alternatives to hiring are worth considering.

Who should you hire first: a CTO, a senior engineer or an agency?

Hire first the person who can take the product to its first users single-handed: usually an experienced full-stack developer or a technical co-founder. The choice depends on whether you are ready to share equity and how much the product depends on technology.

Option	When it fits	Main risk
Technical co-founder	Technology is the core of the product, long horizon	Hard to find; a founder conflict is expensive
Experienced full-stack developer	You need to build and grow an MVP quickly	One person is a single point of failure
Agency or vendor	You need to launch faster than you can hire	Product knowledge sits outside the company
Junior "to grow into the role"	Almost never for a first hire	Nobody to make architectural decisions

The last row is the most common mistake. A junior costs less, but the first developer sets the architecture, stack and infrastructure; mistakes at this stage get rewritten for years. We compared hiring with using a vendor in detail in outsourcing vs an in-house team.

Which qualities matter most in a first developer?

Independence and product thinking matter most in a first developer, far more than knowledge of a specific framework. There is nobody to ask: they decide what to do now, what to postpone and where to simplify without hurting the product.

What to look for:

• experience taking products from zero to real users, not just working in a large team;
• breadth: backend, front end, database, deployment and monitoring at least at a basic level;
• the ability to explain a technical decision in plain words and name its cost;
• willingness to say "we don't need this" — cutting scope for speed;
• a habit of writing tests and documentation, because the next person will inherit the code.

How do you assess a candidate if you cannot read code?

You can assess a candidate without technical knowledge by relying on an outside expert and on actual work, not on how the conversation felt. Confident speech and fluent jargon say nothing about how someone writes code and makes decisions.

A hiring process that works

1. Bring in a technical adviser — a CTO you know or an independent consultant — for an hour or two of final interviews and take-home review.
2. Talk through past projects: what exactly the candidate did personally, which decisions they made, what they would do differently.
3. Give a paid take-home task of 1–3 days that resembles a real product task.
4. Ask them to explain the solution to you and the adviser: why this way, what was simplified, what they would do with more time.
5. Talk to the candidate's former managers or clients.

An example of a good take-home task for a product with user accounts:

Task: an API for a user's list of orders
- sign-up and sign-in by email
- create an order and list your own orders with pagination
- a user cannot see other users' orders
- README: how to run it, what was simplified and why
We assess: does it work, is the code clear, are there tests, is the README honest

Always pay for the take-home: it attracts strong candidates who have no time for free assignments and shows that you value their time.

How much should you pay, and should you offer equity?

Pay your first developer a market salary for an experienced engineer, and offer equity on top if they take on risk and ownership of the technology. Trying to replace salary with a large equity stake usually screens out experienced candidates with families and commitments.

What to discuss and put in writing:

• the size of the stake, the vesting schedule and what happens if they leave;
• the role and scope of responsibility — developer or future CTO;
• who owns the code and work product — this belongs in the contract;
• how the team will grow and who will hire it.

Have a lawyer draft the equity terms: mistakes there surface at the worst moment — during fundraising or when someone leaves.

How do you avoid depending on one developer?

You reduce dependency on a single developer by making sure all access and knowledge belong to the company, not the person. Even if the relationship is great, people get sick, leave or burn out.

Minimum hygiene from day one:

1. Repository, hosting, domains, email and third-party services on company accounts, with the founder as an admin.
2. A README explaining how to deploy the project from scratch.
3. Automated database backups and a verified restore.
4. A short description of the architecture and key decisions.
5. Regular demos — the founder sees what is done instead of reading about it in reports.

With this hygiene in place, replacing a developer or bringing in an agency becomes a routine task rather than a crisis. If you later need an external team, the questions in how to choose a software development vendor will help.

In short

• Hire an experienced full-stack engineer or a technical co-founder first, not a junior.
• Look for independence, product thinking and experience launching from zero.
• Without technical knowledge, rely on an adviser and a paid take-home task.
• Offer equity on top of a market salary and have a lawyer draft the terms.
• Keep all access and knowledge on the company's side from day one.
