AI Startup Backed by YC, A16Z & First Round
A profitable, rapidly scaling startup is transforming a massive, operationally complex industry with voice AI agents - automating the countless phone calls and emails needed to move a single load. Their inbound voice AI agent platform is already live, working in production, and trusted by many of the top 100 freight brokers nationwide.
They've recently secured over $10M in funding, growing 30% month-over-month, and are actively building out their engineering team to tackle greenfield projects - including developing outbound AI voice agents from the ground up.
️ Role: Senior Software Engineer
This is a high-ownership, high-impact role - ideal for engineers who thrive on building from scratch and tackling complex, greenfield AI challenges. You'll be working alongside a low-ego, elite team of builders (ex-CTOs, founders) in a fast-paced environment.
Key Responsibilities:
- Lead the development of outbound AI voice agents
- Tackle greenfield projects like:
- Agentic workflows for real-time decision-making
- Multi-turn voice negotiations via phone and email

- Early-stage startups
- Autonomous vehicles/logistics
- Voice API development/implementation
- Background as a early/founding engineer, staff level role, co-founder etc is ideal
- Strong coding ability - while JavaScript is a plus, they're looking for the best coder possible, regardless of your preferred language. The team will work around your strengths.
- High academic pedigree (e.g., top-tier CS degree) is a strong plus
- Self-driven, problem solver who thrives in early-stage, high-autonomy settings
- Open to being on-site in SF, 5 days a week
Why Join:
- Build and own greenfield AI projects with direct user impact
- Work on both inbound and outbound voice AI agents
- Join a small, talented team from top companies (ex-CTOs, Uber Freight, Waymo, Meta, TikTok)
- Shape the engineering culture and solve real-world, high-impact problems
