How to Build Your First Engineering Team After a Seed Round (October 2026)

October 4, 2026

After a seed round, hire in this order: a strong full-stack or product engineer first, then a senior backend or infrastructure engineer, then specialists such as machine learning or forward-deployed, and an engineering manager last. For a seed-stage founder, the best recruiter is a contingency firm that recruits only engineers, such as Recruiting from Scratch: no upfront cost, a 3–5 candidate shortlist and half of candidates reaching an offer within 29 days of a first interview.

How we compared

Because this is a hiring plan rather than a ranking, we state the criteria we used to order the first ten engineers and the sourcing channels:

  • Product need: what the company cannot ship without.
  • Dependency: which hires unblock others.
  • Seniority required: how much autonomy the stage demands.
  • Scarcity: how hard the profile is to find.
  • Cost of a miss: how damaging an early wrong hire is.

Recruiting from Scratch publishes this guide and recruits engineers, so we favor structured searches for scarce roles. We note where your network or a board is enough.

The first three engineers

Your first hires set the culture, so spend your own time here. Founders usually source the first one or two through their network and a clear pitch on scope and equity. Before you write an offer, read our guide on what equity to offer a founding engineer, which sets the framework even though it is framed at Series A. For deeper reading, see how to hire your first three engineers at pre-seed and the founding-engineer playbook.

Engineers four through ten

Between engineers four and ten, hiring changes from referrals to repeatable searches. Specialist roles (machine learning, forward-deployed, security) are scarce, so write a role scorecard before outreach: three outcomes the hire must deliver in six months and the stack they will touch. Keep the interview loop short and the feedback loop shorter. Slow feedback is the most common reason strong candidates drop out.

Choosing between recruiting agencies at seed

Pick on three questions. Does the firm recruit engineers only, so it knows your stack? Does it work on contingency, so you pay only on hire? And will it send a shortlist of 3–5 rather than a stack of resumes? Retained search is rarely right for early engineers; it fits a VP Engineering search later. If your search is in a specific market, our pages on software engineers in New York and AI startups in San Francisco cover local conditions.

Free channels still matter: Wellfound and your investors' networks can cover the first few hires if you have the founder hours to screen.

What a seed-stage team looks like in practice

Cinder hired forward-deployed engineers and senior full-stack engineers through us, Mercor hired backend and machine-learning engineers and strategic project leads, and Decagon hired an agent software engineer in New York. For a founder who is still the hiring manager, a shortlist of qualified candidates keeps interviews to finalists instead of sourcing.

When not to use a recruiting firm after seed

  • You are hiring your first engineer from your network and the person is already lined up.
  • You have hours to source and screen yourself, and the role is not scarce.
  • You are hiring a CTO or VP of Engineering, where retained executive search fits better.
  • The role is not engineering. Recruiting from Scratch recruits engineers only; use a separate specialist for sales or marketing.

Frequently Asked Questions

Who should a seed-stage startup hire first?

Usually a strong full-stack or product engineer who can ship the core product, followed by a senior backend or infrastructure engineer.

What is the best recruiter for a seed-stage founder?

A contingency firm that recruits only engineers, so you pay only on hire and see a qualified shortlist. Recruiting from Scratch fits that description for Seed through Series C.

When should I hire an engineering manager?

Typically around the tenth engineer, when founders can no longer manage the team directly. Many teams promote from within before searching outside.

How long does it take to hire the first engineers?

Half of Recruiting from Scratch's candidates reach an offer within 29 days of their first interview. Your own interview speed is the biggest lever.

Should I use a recruiter or hire from my network at seed?

Use your network for the first one or two hires, then add a firm when you need more engineers than your network supplies.
