What you'll do
- Hire and scale the engineering organisation, building a strong 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.
- Stay close to the work through design review.
What we're looking for
- 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.
- Engineering leadership: you build strong teams, strong leaders, and clear accountability.
- Execution: you create predictability and drive complex programmes through to completion.
- Technical judgement: you can guide architecture and challenge senior engineers without becoming a bottleneck.
- Systems thinking: you understand organisations, platforms, and operating models as interconnected systems.
- Operational mindset: you expect engineering output to be reliable, supportable, and production-ready.
- Organisational design: you know when structures, processes, or ownership models need to evolve.
- Calm leadership: you remain decisive under pressure and make clear trade-offs when required.
- Ownership: you take responsibility for engineering outcomes, organisational health, and long-term capability.
Nice to have
- Experience with cloud or infrastructure platforms, scaled SaaS, AI/ML platforms, or infrastructure-heavy technology businesses is strongly preferred.
