Senior Engineers — SF | YC AI Startup | Backed by A16Z & First Round

I've been retained by the founders of a YC startup that's raised $17M+ from A16Z and First Round to help them find a few strong senior engineers.

The product:

AI voice agents that automate freight booking — replacing the repetitive, manual work brokers do to move a single load. It's live in production, and already being used by many of the top 100 brokerages in the U.S..

They are already profitable, and growing 30% month-over-month.

They've already built the internal agent platform. Now they're starting fresh on a new outbound voice product — and this is where you come in.

What you would be doing:

• Developing multi-turn negotiation capabilities for both voice and email.
• Designing agentic workflows with true autonomy.
• Crafting high-quality, believable voice synthesis.
• Building real-time infrastructure for critical AI systems

This is core product, not support tooling. You'll be building things that ship — fast — alongside a team of ex-CTOs and early engineers from Waymo, Uber, Meta, etc. It's a low-ego, high-agency environment where you'll own what you build.

What they're looking for:

• Experience in an actual engineering role (not school, not internships)
• Strong technical fundamentals — language doesn't matter
• Startup experience is a big plus

Location: SF (SoMa) — in-office, 5 days/week

This isn't for everyone — but if you're someone who wants to build hard, useful, hard-to-replicate systems with a sharp, focused team, reach out to ...@alexanderchapmanltd.com or apply directly here.
