Job description

This role is with one of Dex's trusted partner companies. We work closely with their teams to truly understand their culture, goals, and what they're looking for, so we can match you with the right opportunity and give you context about the role before you commit to a process.

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.
