Job description

We’re partnering with an early-stage SaaS startup that’s building an AI platform designed to help organisations operating in regulated industries manage risk, improve compliance and make better decisions as AI adoption continues to accelerate.

With growing customer demand and an ambitious product roadmap, they’re now looking to hire a Product Engineer to join their team over the coming weeks.

This is an opportunity to join a small, highly collaborative team where you’ll work directly with the founders to shape the future of the product. You’ll have real ownership from day one, building features end-to-end and helping influence technical decisions as the platform evolves.

• Building and shipping product features across both the frontend and backend
• Working closely with the founders to shape product direction and technical decisions
• Designing scalable, maintainable solutions that solve real customer problems
• Collaborating with product and engineering to deliver high-quality software
• Taking ownership of projects from idea through to production
• Contributing to architecture, code reviews and engineering best practices
• React, TypeScript, Node.js
• Redis
• AWS

What we’re looking for

• Strong experience building modern web applications across both frontend and backend
• Commercial experience with React and TypeScript
• Experience working with Node.js or similar backend technologies
• Cloud experience (AWS preferred)
• Someone who enjoys solving complex technical problems
• Startup mindset with a willingness to take ownership
• Comfortable working in a fast-paced, collaborative environment

Experience working within SaaS, cybersecurity, AI or regulated industries would be beneficial but isn’t essential.

What’s on offer

• Salary of £60,000-£90,000
• Hybrid working (2-3 days per week in London)
• Opportunity to help shape an AI product from an early stage
• Direct exposure to founders and real influence over the product roadmap
• Small, collaborative engineering team where your work will have immediate impact

If you’re looking for a role where you’ll have genuine ownership, work closely with founders and build technology that solves meaningful challenges for customers, we’d love to hear from you.
