Job Description:

Head of Software Engineering (Engineering Manager) – Native AI & Agentic Workflows, React, C#, AWS

Lead. Elevate. Ship.

Outstanding opportunity to join a cloud native, product centric SaaS business that’s modernising at pace, investing heavily in engineering excellence (native AI & agentic workflows), and giving leaders the autonomy to shape the build of an enterprise platform on a greenfield basis.

You’ll influence culture, delivery, architecture and outcomes, while working with talented people who genuinely care about doing things the right way.

What you’ll be doing:

  • Reporting directly to the VP of Engineering, you’ll take ownership of an engineering group made up primarily of contract resource (c.10–20 engineers). You’ll set the tone for a high‑performance, inclusive culture and ensure teams are aligned, supported, and shipping consistently
  • Leading and line‑managing a multi‑squad engineering group, creating clarity, accountability and momentum
  • Partnering with Product to ensure squads are balanced, aligned to business goals, and delivering value each cycle
  • Championing modern engineering practices across SDLC, CI/CD and QA, automation‑first, test‑first, and “always ship each cycle”
  • Collaborating with Architecture, Security, DevOps and QA to deliver secure, well‑architected services on a shared platform
  • Acting as the principal point of escalation for contract resource and ensuring blockers are removed quickly
  • Support people operations: hiring, onboarding, 1:1s, reviews, leave and contract‑specific considerations.
  • Drive agentic AI development practices across teams
  • Ensure contractors have the right tools, processes and guardrails to deliver consistently and efficiently
  • Report progress, risks and issues to Senior Leadership with clarity and confidence
  • Champion secure‑by‑design principles, data governance and timely CVE remediation in partnership with the CISO team
  • Support GTM with technical insight to strengthen product marketing, sales enablement and customer outcomes

Key requirements:

  • Proven experience as a senior engineering leader, managing multiple squads and c20 engineers across delivery and operations
  • A strong technical foundation, ideally full‑stack, with exposure to AWS, C# .NET, TypeScript, Node & React
  • Deep expertise in modern SDLC, agentic AI‑driven development, testing practices, automation and CI/CD (GitHub Actions experience ideal)
  • A strong grasp of secure software development, data governance and vulnerability management
  • Confident stakeholder management across senior leaders and strategic customers; calm, clear communication under pressure

£105k – £110k + bonus. London & 90% remote. 12-month Fixed Term Contract.
