• Work closely with product and engineering groups to ensure platform consistency

What You’ll Bring:

• Demonstrated leadership experience in scaling technical teams within fast-moving environments
• 10+ years of hands-on engineering experience, with extensive use of AWS
• Deep familiarity with platform engineering or infrastructure roles in a SaaS business ideally
• Proficiency with modern DevOps practices, container orchestration (e.g. Kubernetes), infrastructure-as-code, and monitoring stacks
• History of managing teams, ideally remote
• A track record of delivering complex technical initiatives at speed
• Excellent written and verbal communication, with the ability to align technical and business goals

? Bonus if you have:

• Familiarity with Python, Django, or Golang
• Contributions to open-source communities or tools
• Working knowledge of Postgres, Terraform, and CI/CD pipelines (e.g. GitHub Actions)
• Interest or experience in developer productivity tools and AI-assisted engineering
• Understanding of network systems, protocols, or distributed computing challenges

What's on Offer ?

• Salary up to £125k + equity + bonus
• 100% remote from anywhere in the UK
• Unlimited holiday
• Company wide events and team socials
• High-trust, high-impact culture
• Work with cutting-edge open-source tools in a collaborative, fast-moving environment
