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.
The next hires
Whether they’ll help hire the engineers who follow, and how much say they’ll have in who joins.

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.

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.

Questions about hiring a founding engineer in NYC
A founding engineer is one of the first engineers at a startup, often hired before or soon after the first funding round. They take broad responsibility for the early product: building the first versions, making core technical decisions and often shaping how the engineering team grows. They’re usually an early employee rather than a co-founder.
A technical co-founder joins as a founder, with responsibilities that extend across the business. A founding engineer is usually an early employee with substantial technical and product ownership. Titles vary, so we define the actual authority, expectations and relationship with the founders before starting the search.
Start with the work that is blocking progress. Broad product delivery may call for a generalist. A central challenge involving model behavior, evaluation or applied AI may require a founding AI engineer. The fact that your company builds an AI product does not make every engineering position an AI specialist role.
Yes. We work alongside founders and internal talent teams, particularly when the search needs candidates outside your existing applicant pipeline. We agree who owns outreach and candidate communication so people get a consistent introduction to your company. Tell us who you’re already speaking to before we start and we won’t approach them, so there’s never a question of who introduced whom.
Yes. We make the attendance requirement part of the brief from day one: office location, expected days together and any flexibility. Those details decide who can realistically consider the role, so we settle them before interviews begin.
For well-calibrated searches, we can have exceptional candidates in process within the first few days. Our average hire takes 17 days from submission to accepted offer.
Yes. We can approach candidates without naming your company until they’re qualified and interested, and we only share details with your agreement.
We tell you. Fast. Because we map the market from the beginning, we can usually see whether the issue is sourcing, compensation, location, interview process or simply an unrealistic profile. We bring that data back to you and recalibrate rather than spend six weeks quietly sending increasingly weaker candidates.
We offer retained search, embedded partnerships and success-based arrangements, and the structure depends on the hire. Embedded partnerships use a monthly fee plus a reduced success fee. Single searches are retained or success-based. We agree fees and responsibilities upfront, so you understand the engagement before the search begins.
