About this role

In this role, you will design and build distributed systems and APIs for high-dimensional simulation data, focusing on the machine learning lifecycle. You'll collaborate closely with the infrastructure team, mentor other engineers, and remain hands-on with coding. The position requires strong communication skills and adaptability in a fast-paced environment, as the scope may evolve due to team reorganization.

Scored from the posting itself — how clearly the role is described, how much it says about pay and benefits, and how recently it was listed. Not a judgement of PhysicsX as an employer.

What you need

  • Strong Kubernetes experience, including comfort with CRDs, Operators, and infrastructure configuration tools such as Helm or ArgoCD
  • Strong command of Go, plus working knowledge of Python
  • Experience deploying and supporting services in more than one production environment
  • An ML platform background or prior data science experience
  • Strong communication and organisational skills
  • Prior experience mentoring or developing other engineers

Nice to have

  • Comfort with Rust
  • Experience at an ML focused startup or platform company
  • Understanding of what it takes to build and support software across cloud, on premises, and air gapped environments
  • Experience with big data systems and analytics at scale in production
  • Side projects, open source contributions, or things you have built for their own sake

What you get

  • Equity options
  • 10% employer pension contribution
  • Free office lunches
  • Flexible working
  • Hybrid setup
  • Enhanced parental leave

Worth weighing

  • The role may evolve as team structures settle, so the scope is intentionally broad
  • This is a software engineering role, not an ML research role, so a focus on coding is expected
  • The company is in a fast-paced environment where priorities shift frequently
