About Warden AI

Warden AI helps HR Tech vendors, staffing firms, and employers prove and improve the fairness, accuracy, and compliance of their AI hiring systems. In a fast-changing regulatory environment, organizations need a trusted partner to validate their AI, and Warden is quickly becoming the default solution. In 2025, Warden grew from 4 to 40 customers. In 2026, we've already more than doubled ARR and are growing faster every quarter. That growth is driven not just by market demand, but by something rarer: a genuine network effect. Customers want to promote working with Warden because it helps them win their own deals.

About The Role

We are hiring a Full-stack Product Engineer to help build and evolve the core product experiences of Warden's AI assurance platform. The role spans frontend product development and backend services, turning complex analytical and audit workflows into clear, reliable software that customers can trust. You will join an existing engineering team and report to the CTO, working closely with product, data, and customer-facing teams. A strong candidate will bring a solid background in TypeScript and React, helping strengthen the team's full-stack product development capabilities, particularly across TypeScript, React, and Next.js, while contributing to backend systems in Python. Your work will have visible impact on product quality, usability, and reliability across the platform. As one of our early product engineering hires, you will help shape how this role grows over time and take on more responsibility across product development as we scale.

What You'll Do

Here are a few examples of things you might be working on:

• Build end-to-end product features, e.g. design and implement new dashboards, workflows, and UI components that help customers understand and act on AI audit results
• Lead on frontend experiences, e.g. develop polished, accessible interfaces, working closely with product and design to get details right
• Contribute to backend services, e.g. extend services that power audits, reports, and internal tooling, and wire them cleanly into the frontend
• Translate product requirements into working software, e.g. break down loosely defined problems, propose pragmatic solutions, and iterate quickly based on feedback
• Improve product quality and reliability, e.g. fix bugs, reduce edge cases, improve performance, and strengthen type safety and test coverage
• Collaborate cross-functionally, e.g. work closely with data scientists, solutions engineers, and founders to ship features that solve real customer problems
• Continuously improve the codebase, e.g. refactor areas you touch, improve developer ergonomics, and contribute to shared patterns and conventions

What you should bring

• A self-starting, get-it-done attitude. You're comfortable with ambiguity, take ownership, and move from idea to working software without needing constant direction
• Strong TypeScript and React experience. You've shipped real, user-facing features and care about code quality, usability, and maintainability. Experience with Next.js is a plus
• Full-stack mindset. You're happy
