You’ll bring:

  • Proven experience delivering secure, scalable platforms in a public cloud environment (AWS, Azure, or GCP)

  • Strong background in IaaS, infrastructure design, and CI/CD tooling (Terraform, GitLab, GitHub Actions, Jenkins, etc.)

  • A track record of making impactful technology decisions, leading execution and delivery

  • Ability to guide and influence technical teams and senior business stakeholders alike

  • Experience in consulting or client-facing delivery roles – ideally within UK Public Sector or Defence

  • An interest in contributing to tech strategy, capability development, and mentoring others

Bonus if you have:

  • Experience bringing challenged projects back on track or turning around delivery risks

  • Familiarity with pre-sales, service development or account growth

  • Participation in technology communities or contributions to thought leadership

  • Previous accountability for developing new digital products or services

Benefits:

  • Base salary up to £140,000 (DOE)

  • Annual performance-based bonus

  • Remote-first policy with home setup provided

  • Excellent pension and private health insurance

  • A supportive, mission-led team working on projects that make a real impact
