For a Los Angeles defense or aerospace startup hiring software engineers between Seed and Series C, Recruiting from Scratch is a fit for the engineering roles that don't require an active clearance: 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. For roles that need a clearance in hand, a cleared-talent specialist is the better choice.

Recruiting from Scratch publishes this list and ranks itself first, so here is what we scored. We don't claim cleared-recruiting specialization. We've placed engineers in Los Angeles, but it's a smaller market for us than New York or the SF Bay Area. Five criteria:
| # | Firm | Best for | Stages | Roles | Model |
|---|---|---|---|---|---|
| 1 | Recruiting from Scratch | Software engineers without a day-one clearance requirement | Seed to Series C | Backend, full-stack, AI/ML, forward-deployed | Contingency, replacement guarantee |
| 2 | Cleared-talent search specialists | Roles needing an active clearance | Any | Cleared engineers and analysts | Specialist agency fee |
| 3 | Riviera Partners | Engineering leadership | Venture-backed, seed to late stage | VP Eng, CTO | Retained search |
| 4 | Motion Recruitment | Broad IT placement | Growth and enterprise | Wide range of technical roles | Agency fee |
| 5 | Hunt Club | Senior hires via referrals | Venture-backed and growth | Senior and leadership roles | Search fee |
| 6 | Veteran and transition networks | Separating service members with technical skills | Any | Entry to mid-level technical roles | Programs and job boards |
Best for: Los Angeles defense, space and national security startups building a software team from Seed through Series C.
Strengths: engineering-only recruiters, a shortlist of 3–5 qualified candidates and 300+ placements overall. We place software engineers at defense companies, and Cinder has hired forward-deployed engineers through us, a role that maps to the field-facing seats these startups fill.
Limitations: we are not a cleared-recruiting specialist. We don't hold a facility clearance or run cleared-only searches, Los Angeles is a smaller market for us than New York or the SF Bay Area, and we don't recruit non-engineering or C-suite roles.
Best for: roles that require an active Secret or higher clearance on day one.
Limitations: the cleared pool is small, and these firms are rarely startup-specific.
Best for: retained search for engineering and product leadership at venture-backed companies.
Limitations: not designed for a run of individual-contributor hires.
Best for: broad IT and technical placement.
Limitations: breadth over defense-startup depth.
Best for: senior and leadership hires through a referral network.
Limitations: less suited to volume engineering hiring.
Best for: separating service members, many of whom carry mission context and sometimes a clearance.
Limitations: not a recruiting partner. You run the process yourself.
Southern California has long been a center of aerospace and defense work, with activity concentrated around El Segundo, Hawthorne and Long Beach. A newer generation of venture-backed startups now hires alongside established primes, which shapes the market in three ways: engineers with flight, satellite and embedded backgrounds are around, startups compete with large established employers for them, and many candidates weigh mission against stability.
Startups here hire backend and full-stack engineers, embedded and systems engineers, ML engineers for perception and autonomy, and forward-deployed engineers who deploy software to operators. Some roles carry constraints that change the search:
Be honest about which category each req falls in. Our guide to defense tech startups covers the national picture, and software engineers at defense companies covers roles. For firmware and systems seats, see embedded engineers.
Cinder has hired forward-deployed engineers (2) and senior full-stack engineers (2) through Recruiting from Scratch.
Split your reqs in two. Use a cleared specialist for roles requiring an active clearance, and a contingency engineering agency for the rest, so you pay only on hire. Ask each agency how it verifies citizenship and clearance status and at which stage.
For software engineers without an active-clearance requirement, Recruiting from Scratch: engineering-only, contingency pricing and half of candidates reaching an offer within 29 days of a first client interview. For cleared roles, start with a cleared-talent specialist.
We place software engineers at defense companies, but we are not a cleared-recruiting specialist. If a role requires an active clearance on day one, start with one.
It is the Department of Defense program for contractor cybersecurity. It affects how you handle controlled data, including during recruiting, so involve your compliance lead early.
Only for roles with no export-control or citizenship restriction. Check requirements with counsel before searching.
Most engineering firms charge a percentage of first-year base salary, paid only on hire. Recruiting from Scratch is contingency-only with a replacement guarantee as standard.
