Job Description


Why Join as a Founding Engineer?

There are plenty of opportunities to join a startup.

Very few let you join one with meaningful scale already behind it, a world-class team already assembled, and still enough surface area left to shape what gets built.

This is one of those opportunities.

We’re working at the intersection of deep technology and modern cloud infrastructure — building systems that push technical boundaries rather than incrementally improving what already exists. The problems are difficult, the engineering bar is high, and the work sits close to the core of the product.

The company has recently raised $30M Series A and, rather than scaling headcount aggressively, has deliberately built a small team of exceptional engineers.

Today, engineering sits at around 10–15 people.


That team includes people who have:

  • built and scaled products at global technology companies
  • founded and exited startups
  • operated in high-performance engineering environments
  • shipped products used at significant scale

The philosophy is simple: keep the team small, keep standards high, and give exceptional people room to do the best work of their careers.


What You’ll Actually Work On

This is a backend-leaning, product-focused role.

You’ll work on:

  • distributed cloud systems
  • highly scalable backend architecture
  • infrastructure and platform capabilities
  • complex system design challenges
  • performance, reliability and developer tooling
  • translating difficult technical problems into products customers use

You’ll work closely with product and founders and be trusted to own problems end-to-end.

This isn’t an environment where engineering operates as a service function.

Engineering drives outcomes.


If your background is in:

  • Python
  • Java
  • Go
  • Rust
  • or similar backend ecosystems

you should absolutely apply.

Strong fundamentals, system design ability, product instinct and the ability to learn quickly matter significantly more than prior experience in a specific language.

Who They’re Looking For

They’re looking for strong senior engineers who want difficult technical work and high ownership.

Typical backgrounds might include:

  • 3+ years of commercial software engineering experience (many hires have more)
  • strong backend engineering fundamentals
  • experience building production systems
  • excellent academic track record
  • ideally a First Class degree (or international equivalent) from a highly regarded university
  • people who enjoy moving quickly while maintaining engineering quality

The common thread across the team isn’t a particular language or company background.

It’s intellectual curiosity, technical depth, and ambition.

The Environment

  • Recently raised $30M Series A
  • Lean engineering team (~10–15 engineers)
  • High technical standards
  • Deep collaboration with founders
  • Visa sponsorship available
  • Office-first environment in a premium workspace
  • Designed for engineers who enjoy working together in person


If you’re excited by working on difficult problems, surrounded by exceptional engineers, with enough ownership to genuinely influence the direction of a company — this is worth a conversation.
