Job summary

Radiant Hybrid in London is seeking a Head of Engineering to lead the engineering organisation and ensure execution, quality, reliability, and scalability of AI infrastructure.

You'll build a 30-35 engineer team today, growing to 150-200+ as we expand internationally, collaborating with Product, the Customer team, Infrastructure, SRE and Operations.

This senior role requires building high-performing teams and shaping the roadmap, while maintaining hands-on involvement in design reviews.

Qualifications

• Senior leadership of engineering orgs with 20+ engineers
• Experience hiring and developing engineering managers and senior engineers
• Proven track record delivering large-scale AI infrastructure
• Ability to design scalable operating models
• Strong collaboration with product and operations

Responsibilities

• Hire and scale the engineering organisation with a leadership layer across Engineering Managers, Principal Engineers, and senior technical leaders.
• Own engineering hiring, performance, leadership development, succession planning, and organisational health.
• Design and evolve the engineering organisation as the company scales across teams, sites, and regions.
• Own the engineering strategy, operating model, and execution in alignment with company and product objectives.
• Translate business priorities into clear technical plans, sequencing, investment decisions, and delivery commitments.
• Establish clear ownership, decision-making, and accountability across engineering teams.
• Drive predictable, high-quality delivery, identifying risk early and intervening where execution drifts.
• Ensure systems are designed and delivered to be production-ready, reliable, observable, maintainable, and supportable.
• Strengthen collaboration with infrastructure, SRE, and operations, including effective handover and incident learning.
• Set and uphold standards across architecture, engineering quality, security, scalability, and operational maturity.
• Own the roadmap jointly with Product: Product owns what is built, and you own how and when.
• Act as the senior escalation point for critical technical, architectural, and delivery decisions, brokering decisions between peers and escalating to the CTO when needed.
• Improve engineering maturity and processes while avoiding unnecessary bureaucracy or loss of delivery momentum.
• Represent engineering in executive and partner discussions, and join customer escalation reviews with the Customer team.
