Founding Product Engineer

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.

This company is building a platform that automates mission-critical workflows for enterprise applications that don't support standard SSO. This isn't just automation; it's about securing the long tail of enterprise access, protecting against sophisticated threats for major financial and insurance clients. They are defining a new category, building browser-using agents for work where reliability is non-negotiable.

This is a founding product engineering role. You'll own significant surface area across the on-device browser agent, the browser extension, and the web dashboard. You'll build the core automation engine, the user-facing workflow builder, and critical security infrastructure. This isn't a role where you're handed specs; you'll work directly with enterprise customers, identify problems, and ship solutions to production within days.

• Design and build the core browser automation engine, ensuring extreme reliability for mission-critical enterprise workflows.
• Develop the user-facing workflow builder, enabling non-technical users to configure complex automation sequences.
• Strengthen end-to-end encrypted infrastructure, protecting sensitive customer data against sophisticated threats.
• Own features end-to-end, from direct customer feedback to production deployment within days.
• Contribute across the full stack: on-device browser agent, browser extension, and web dashboard.

• 1+ year of experience building client-side software (desktop, browser, or web) with end-to-end product ownership.
• A strong product mindset: you care deeply about UX, design, and the user experience of what you ship.
• Eagerness to engage directly with enterprise customers, translating their problems into rapid, impactful solutions.
• Proven ability to thrive in a high-ownership, high-intensity environment, shipping fast and inventing new solutions.
• Hands-on experience with or a strong desire to master technologies like Type Script, Electron, browser extensions, Puppeteer/Selenium, or E2E encryption.
• Eligible to work in the UK or US.

This is a rare founding role, not one you'll find easily or apply to cold.
