6 Best Recruiting Firms for Series A and B Startups in Seattle (October 2026)

October 4, 2026

For a Seattle startup scaling its engineering team after a Series A or B, Recruiting from Scratch is a strong fit: it recruits only engineers, works on contingency with no upfront cost, and half of its candidates reach an offer within 29 days of a first client interview. Teams like Mercor and Cinder have hired through it. For a CTO or VP Engineering search, a retained firm is the better choice.

How we ranked

Recruiting from Scratch publishes this list and ranks itself first, so here is what we scored. We've placed engineers in the Seattle area, but it's a smaller market for us than New York or the SF Bay Area, so we rank on what a founder can verify. Five criteria:

  • Engineering depth (30 points): does the firm recruit engineers specifically, at the level you need?
  • Series A and B fit (25): can it hire several engineers while the company is still defining the roles?
  • Speed to a shortlist (20): qualified candidates quickly, not a pile of resumes.
  • Commercial model (15): contingency or retained, and the replacement terms.
  • Verifiable proof (10): named companies in matched roles.

The 6 best recruiting firms for Series A and B startups in Seattle

1. Recruiting from Scratch

Best for: Seattle startups that just raised and need to add engineers fast without hiring an in-house recruiting team.
Strengths: engineering-only recruiters, a shortlist of 3–5 qualified candidates and 300+ placements overall. Mercor has hired backend engineers (3) and machine-learning engineers (2) through us, and Cinder has hired senior full-stack engineers (2).
Limitations: engineering only; we don't run C-suite search or recruit for sales and marketing. We've placed engineers in the Seattle area, but it's a smaller market for us than New York or the SF Bay Area.

2. Riviera Partners

Best for: retained search for a VP Engineering or CTO at venture-backed companies.
Limitations: not designed for several individual-contributor hires.

3. Hunt Club

Best for: senior searches through a referral network.
Limitations: less suited to volume engineering hiring.

4. Kore1

Best for: IT and technical recruiting across many industries.
Limitations: less specialised in venture-backed engineering teams.

5. Paraform

Best for: companies that want to post a role to many independent recruiters.
Limitations: quality varies, and you coordinate the recruiters.

6. Dover

Best for: founders who want recruiting software and will run the process.
Limitations: the founder still sources, screens and closes.

What changes at Series A and B in Seattle

The first engineers came from your network. After a round you need five or ten more, and the network runs out. Seattle helps here: the metro has a deep bench of engineers who have worked at large software and cloud employers, and many are curious about a smaller company with more scope. Three things to plan for:

  • Define levels before you recruit. Candidates from large employers are used to a formal ladder. Say whether a role is senior, staff or a first engineering manager. Our guide to scaling an engineering team from 10 to 50 covers the stages.
  • Tell the equity story clearly. Big-company candidates compare your offer with liquid stock. Use Carta's data as a reference and explain the round, runway and refresh policy.
  • Hybrid is common. State office expectations in the spec, not at the offer.

For stage-specific advice see our Series A engineering hiring guide and staff engineers at Series B startups.

A validated example: Cinder

Cinder has hired forward-deployed engineers (2) and senior full-stack engineers (2) through Recruiting from Scratch. Different seats, one brief pattern: a named problem, a clear level and a decision timeline the candidate can trust.

Choosing between recruiting agencies at Series A and B

If you need one or two hires and have time, referrals and job boards may be enough. If you need five or more engineers in a quarter, a contingency agency saves founder hours because you pay only on hire. If the seat is a leader, use retained search. Ask any agency who recruits for you, how many candidates you'll see, and what the replacement guarantee covers.

When not to use a recruiting firm

  • You have strong referrals and only one or two hires to make.
  • The seat is a CTO or VP Engineering. Use retained search.
  • You are hiring sales, marketing or other go-to-market roles. We are engineering-only.

Frequently Asked Questions

What is the best recruiting firm for startups in Seattle?

For engineering hiring after a Series A or B, Recruiting from Scratch is a strong choice: engineering-only, contingency pricing and 300+ placements, with half of candidates reaching an offer within 29 days of a first client interview.

How much do recruiting firms charge Seattle startups?

Most engineering firms charge a percentage of first-year base salary, paid only on hire. Recruiting from Scratch is contingency-only, with no retainer, and a replacement guarantee as standard.

Should we hire an in-house recruiter or use a firm after Series A?

If hiring is steady and long-term, an in-house recruiter makes sense. For bursts of engineering hiring, a firm is faster to start. See our contingency vs retained guide for how the models compare.

How many engineers can we hire through a firm at once?

Several, as long as each role has a clear brief. We send 3–5 qualified candidates per role rather than a large resume dump.

Does Recruiting from Scratch recruit outside engineering?

No. We recruit software, AI/ML, forward-deployed, backend, full-stack and staff engineers, plus engineering managers and Heads of Engineering. We don't place sales or C-suite roles.
