London - Ideally 2 days/week

£130k - £150k base + equity + bonus + benefits

We have partnered with a scale up company who are building cutting edge physical AI systems. They've seen rapid growth (600%+ revenue growth over 3 years), raised significant funding (~$170M), and are working on genuinely mission critical systems.

They're hiring a Principal Engineer to lead a small team while remaining highly hands on.

Key details:

• Proficiency in TypeScript, React, and state management (Zustang, Jotai, Redux, MobX).
• Proficiency in Python and Go, with experience in other languages a plus (Rust, C++)
• Strong experience deploying applications on Kubernetes, leading to a high level of independence in writing IaC (Helm, Terraform, Crossplane) and CI/CD workflows.
• Experience with workflow orchestration, event-driven systems, and messaging (NATS, ArgoWorkflows)
• Proven track record building web-based user interfaces using a variety of architectural approaches - SPAs, server-rendered applications, hybrid architectures, micro-frontends - with a critical perspective on when each is the right choice.
• Some team lead/management experience, will be leading a team of 4/5 engineers, must be super hands on though
