Senior Product Engineer | £80-100k + Equity | Series A SaaS | London


We’re working with a high-growth Series A SaaS company that’s building a genuinely exciting product for modern organisations.


They’re taking complex internal processes and making them simpler, smarter and easier to manage, combining great product design with powerful integrations and a highly scalable technical platform.


Having recently reached Series A, they’re at a really exciting stage of growth. The engineering team is still small enough for you to have a real impact on the product and technical direction, but with the backing and momentum to build something at scale.


🚀 The Role

This is a hands-on Senior Product Engineer role for someone who enjoys having ownership across the stack and being close to the product.


You’ll:

  • Own features from initial idea through to production
  • Build end-to-end functionality across the product
  • Work primarily with React and Node.js
  • Contribute to architecture and technical decisions as the platform scales
  • Work closely with Product and Design to turn ideas into high-quality products
  • Have a genuine voice in how the engineering team and product evolve


What They’re Looking For

  • 7+ years’ experience as a Full Stack / Product Engineer
  • Strong React and JavaScript/TypeScript experience
  • Node.js experience is ideal, but they’re open to engineers from other backend language backgrounds who are happy to work with Node
  • Experience working in a SaaS, startup or other fast-paced product environment
  • Comfortable taking ownership and operating with a high degree of autonomy
  • Strong product mindset and an interest in working closely with Product and Design
  • Someone who wants to make a tangible impact rather than simply picking up tickets


What’s On Offer

  • £80-100k + Equity
  • Series A SaaS company with strong growth trajectory
  • 3 days a week in Central London
  • Significant ownership over product and technical direction
  • Opportunity to join at an exciting stage before the team scales further


If you’re a Senior Full Stack / Product Engineer with strong React experience, and you're open to working with Node.js regardless of your current backend language, this is a great opportunity to join a Series A product team at a pivotal stage of growth.
