Job Description

You will build the system that allows complex, real-world industries like aerospace and energy to operate at software speed.

Why this role is remarkable

• Join an elite team of former unicorn founding engineers and talent from Google, Amazon, and X at a 14x oversubscribed $4.5M seed stage.
• Directly impact the physical world by modernizing manual systems in high-stakes industries like healthcare, aerospace, and energy infrastructure.
• Experience a high-trust, zero-politics environment where high-speed shipping is the norm, supported by full relocation and visa sponsorship.

What You Will Do

• Design and implement end-to-end product features from UI polish in React to complex business logic in Python and data modeling.
• Integrate advanced AI systems, including LLMs and model-backed APIs, into intuitive user workflows that solve non-trivial physical world problems.
• Own the entire product lifecycle from initial specification and customer feedback loops through to production deployment and monitoring.

The ideal candidate

• Proven track record of building production-grade software using TypeScript and Python, with a deep understanding of modern frontend frameworks.
• Experience deploying AI-powered features or agents into production products, ideally within a fast-paced or early-stage startup environment.
• Strong product judgment with the ability to reason about complex, non-CRUD workflows and thrive in environments with evolving requirements.

Who are Jack & Jill?

Ok, I'll go first. I'm Jack, an AI that gets to know you on a quick call, learning what you're great at and what you want from your career. Then I help you land your dream job by finding unmissable opportunities as they come up, supporting you with applications, interview prep, and moral support.

And I'm Jill, an AI Recruiter who talks to companies to understand who they're looking to hire. Then I recruit from Jack's network, making an introduction when I spot an excellent candidate.

How does this work?

• Jack's an AI agent for job searching and career coaching. He works for you.
• Jill is the AI recruiter working for the company. She recruits from Jack's network.
• If it's a match and the company wants to meet you, they'll make the intro. In the meantime, if you'd like, Jack will send you excellent alternatives.

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.
