Job description

The role

This company builds AI agents that automate customer acquisition and retention for major banks and financial institutions. They’re tackling a complex problem in a critical sector, backed by leading investors and showing strong traction towards their Series A. The team is small, fast-moving, and highly academic, with many ex-founders.

This Product Engineer role is for a full-stack builder who ships AI-powered products directly to enterprise partners. You'll own features end-to-end in a Node and TypeScript environment, working with genuine autonomy. This isn't a generalist role; it's for an IC who goes deep, executes with velocity, and brings a sharp product instinct to complex AI challenges.

The work

• Design, build, and ship full-stack features for AI agents, directly impacting major financial institutions.
• Own product development end-to-end, from initial concept and user instinct to production deployment.
• Integrate AI capabilities into core product features, moving beyond experimentation to live, user-facing solutions.
• Leverage AI tooling in your own development workflow to maximize execution velocity.
• Work in short cycles, seeing your contributions reach live partners rapidly.

What You Bring

• Proven full-stack engineering experience with Node and TypeScript, owning features from concept to production.
• A track record of shipping AI-powered products to users, not just experimenting.
• Fluent use of AI tools in your personal development workflow.
• Strong product and user instinct; you build with the end-user and customer context in mind.
• Ability to thrive in a pre-product-market-fit startup environment: self-structured, high-pace execution.
