About the Role
As Head of Engineering, you will lead Radiant's engineering organisation and be accountable for its execution, technical quality, reliability, and scalability. You'll lead software engineering, platform security engineering, and architecture, growing the team from 30-35 engineers to 150-200+. This senior leadership role focuses on building a high-performing engineering organisation capable of delivering and operating complex AI infrastructure at scale, while staying close to the work through design review.
Responsibilities
- Hire and scale the engineering organisation, building a strong leadership layer.
- Own engineering hiring, performance, leadership development, succession planning, and organisational health.
- Design and evolve the engineering organisation as the company scales.
- Own the engineering strategy, operating model, and execution.
- 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.
- Set and uphold standards across architecture, engineering quality, security, scalability, and operational maturity.
- Own the roadmap jointly with Product.
- Act as the senior escalation point for critical technical, architectural, and delivery decisions.
- Improve engineering maturity and processes while avoiding unnecessary bureaucracy.
- Represent engineering in executive and partner discussions.
- Join customer escalation reviews with the Customer team.
Requirements
- Significant experience leading and scaling engineering organisations of 20+ engineers through multiple stages of growth.
- Experience managing managers, with a strong track record of hiring and developing Engineering Managers, senior engineers, and technical leaders.
- Proven experience evolving a smaller engineering group into multiple teams with clear ownership, leadership, and consistent delivery.
- Experience designing organisational structures, team boundaries, and operating models for increasing scale and complexity.
- Demonstrated success improving delivery predictability, engineering quality, throughput, and organisational effectiveness.
- Strong technical background across modern software engineering, distributed systems, cloud platforms, or infrastructure-heavy products.
- Experience owning production systems where reliability, observability, scalability, and operational readiness are critical.
- Comfortable working closely with Product, Infrastructure, SRE, Operations, and Commercial teams.
- Experience operating across multiple teams, locations, or time zones.
- Able to communicate technical risk, trade-offs, and opportunity clearly at executive level.
- Experience with cloud or infrastructure platforms, scaled SaaS, AI/ML platforms, or infrastructure-heavy technology businesses is strongly preferred.
