Back End Developer

Stanford Black Limited

London · England · United Kingdom

Location: London, UK - 5 days a week onsite

I'm partnered with a leading global financial institution that is looking to hire a Backend Developer with Java / Kotlin expertise as a de facto Founding Engineer to help launch a greenfield initiative.

This is an opportunity to join at an early stage and play a key role in designing, building, and scaling a new platform from the ground up, with significant ownership across architecture, engineering, and technical direction.

The successful candidate will have a strong track record of working at significant scale , building distributed systems that support a large number of end users and operate reliably in complex, high-availability environments.

Key Responsibilities

  • Architect and build at scale — design highly scalable, distributed systems capable of supporting a large and growing user base.
  • Own the engineering from the ground up — make high-impact decisions around architecture, technology, and technical direction.
  • Build for resilience — engineer systems that are fault-tolerant, secure, highly available, and built to perform under pressure.
  • Solve genuinely hard engineering problems — identify performance bottlenecks, tackle complex production issues, and continuously improve the platform.
  • Raise the engineering bar — champion modern technologies, pragmatic design patterns, and best practices across the development lifecycle.
  • Ideal opportunity for an engineer who wants genuine 0→1 ownership.

What We're Looking For

  • Strong backend engineering experience with Java and/or Kotlin, building production-grade systems.
  • Proven experience working at significant scale , building platforms used by a large number of end users.
  • Deep understanding of distributed systems , scalability, reliability, and system design.
  • A pragmatic, high-ownership mindset — comfortable making decisions, navigating ambiguity, and solving complex problems.
  • A team-first engineer who shares knowledge, maintains high standards, and helps raise the technical bar around them.
