First technical hire or next founding engineer?

Your first engineer might need to turn a prototype into something customers can use. A later founding hire might join a technical founder who needs another person to own a substantial part of the product. Those searches require different people, even when the job titles match.

So we start with the gap in your team. Who makes the technical decisions today? What can your founders already build? Where does progress depend on bringing someone else in? The answers tell us which mandate to recruit for.

Founding engineer

You need one person to own the early product end to end, with no single technical bottleneck

Founding AI engineer

Model behavior, evaluation or applied AI is the main constraint on your product

Founding full-stack engineer

You need one person shipping across the interface, API and database

Founding backend engineer

APIs, data and infrastructure are what’s holding the product back

Need someone with founder-level responsibility across the business? That’s a technical co-founder, not a founding engineer. See the difference in our FAQs below.

Define what your founding engineer needs to own

We build every brief around decisions and outcomes, not a list of frameworks. It gives candidates a clearer picture of the opportunity and gives your team a consistent way to assess them.

The product

What already exists, what customers can use and what has to ship next. Building a first version, fixing a fragile prototype and supporting paying customers each call for different experience.

Technical decisions

Where speed matters, where reliability matters and which decisions can wait. We set out the constraints they’ll work within, including the team, budget and existing technology.

Customers

How closely they work with users, how much influence they have over priorities and where the founder keeps responsibility.

+ Build the brief

Then we agree the first meaningful milestone: what this person should have delivered in their first 90 days. One person’s responsibilities still need realistic boundaries.

Reach engineers who will consider your NYC AI startup

Most founding engineers worth hiring are already building somewhere else, and they aren’t applying to jobs. Getting their attention takes a credible explanation of the opportunity: the problem, the team, the ownership and why your company is worth joining now.

How we assess founding engineer candidates

We look for evidence of building from zero to one.

An impressive employer or a founding title gives us a starting point for a conversation. The stronger evidence is what the candidate personally built, which decisions they made and how they responded when the original approach stopped working. That’s how we tell someone who contributed to an impressive system from someone who owned the hard parts of it.

Explains decisions in depth

What we check before introducing anyone

  • What they personally built and how much of it they owned

  • The decisions they made when the starting conditions were uncertain

  • The caliber of the people they worked alongside

  • How quickly their career progressed

  • What they’ve built outside work

  • Whether they can explain their decisions in depth

What your technical interviewer validates

  • The engineering depth this job requires

  • An early architecture decision, explained in detail

  • A difficult compromise and what it cost

  • A customer problem that changed the product

  • A system they had to improve after launch

Every introduction comes with context on why we think the candidate clears your bar.

Calibrate salary, equity and founder expectations

A founding engineer weighs the whole opportunity. Salary matters, alongside the equity, the product, the founders, the company’s position and the authority that comes with the role.

Before outreach, we help you settle the questions candidates will ask:

  • What salary range can the company support?
  • How will the equity offer be explained?
  • Which decisions will this engineer own?
  • What support will they have from the founders?
  • What are the NYC attendance requirements?
  • What should they achieve in their first few months?

What if our cash budget doesn’t match the profile?

We tell you before outreach starts, not six weeks in. Then we lay out the options: adjust the scope, the level, the equity or the working arrangement. If the requirements exceed the budget or one person’s realistic capacity, we resolve it early enough to change the search.
