Why this role is remarkable

• Rare opportunity to join as a founding engineer and shape the technical direction of a seed-stage venture from the ground up.
• Backed by top-tier VCs, providing a stable foundation with the agility of a tiny, high-performance team.
• Direct impact on product strategy, working alongside founders to solve complex problems without the overhead of a large platform team.

• Design, build, and deploy production-grade AI systems and LLM-powered features from scratch.
• Collaborate directly with founders to define product roadmaps and translate customer needs into technical solutions.
• Manage the entire engineering lifecycle, from rapid prototyping to maintaining scalable, customer-facing infrastructure.

• Proven track record of shipping production AI systems in a startup environment or small, high-growth team.
• High degree of technical autonomy with the ability to own large, ambiguous product surfaces independently.
• Pragmatic approach to engineering, focusing on speed-to-market and building robust systems without needing a large supporting cast.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
