Skill Requirements
  • Javascript Developer
  • Software Engineering
  • Full Stack Developer

We’re partnering with a rapidly scaling B2B SaaS company building a modern compensation intelligence platform used by fast-growing and enterprise organisations globally. The product sits at the intersection of data, finance, and people — and the engineering challenges are genuinely non-trivial.

They’re looking for experienced TypeScript engineers who want more than just a “senior title” — this is a role for someone who wants ownership, influence, and a clear path to Staff / Lead responsibilities as the company scales.

What you’ll be doing

  • Building and owning core product features end-to-end using TypeScript

  • Designing scalable, maintainable systems in a high-growth environment

  • Working across the stack (primarily backend, with frontend exposure if desired)

  • Collaborating closely with product and leadership on technical direction

  • Mentoring junior engineers and raising the bar for code quality and best practice

  • Taking increasing responsibility for architecture, delivery, and decision-making

What they’re looking for

  • Strong commercial experience as a software engineer in a product-led company

  • Deep experience with TypeScript (Node.js and/or modern frontend frameworks)

  • Proven ability to design and build production systems at scale

  • Comfort taking ownership and making pragmatic technical decisions

  • Clear communication and a collaborative mindset

Why this role stands out

  • Fast progression — genuine opportunity to move into Staff / Lead scope

  • High trust environment with real autonomy

  • Strong product-engineering alignment (engineers influence what gets built)

  • Modern tech stack, clean codebase, and sensible engineering standards

  • Competitive salary, meaningful equity, and strong benefits

This is an ideal role for a senior engineer who’s outgrown their current scope and wants to play a bigger part in shaping both the product and the engineering function as the business scales.
