About the Role
As a Principal Engineer, you will help teams do their best work by improving engineering practices, reducing delivery risk, and fostering a culture of trust, learning, and high standards. You will lead through influence, collaborate across disciplines, and connect technical decisions to meaningful customer and business outcomes. This role combines technical leadership, hands-on contribution, and partnership with product, engineering, and architecture leaders. We value different career paths and welcome candidates who bring varied experiences and perspectives.
Responsibilities
- Own the technical direction and long-term health of a critical business domain spanning multiple delivery teams.
- Act as the senior hands-on technical authority, setting a high bar for architecture, security, reliability, and maintainability.
- Shape and co-own a 12–24 month domain technical roadmap with Product and Engineering leadership.
- Drive sound architectural decisions and trade-offs across scalability, resilience, cost, and time-to-market.
- Define and evolve domain architecture, service boundaries, and integration patterns that enable team autonomy.
- Influence and align teams through strong engineering judgement, data, and clear communication rather than authority.
- Lead complex technical initiatives including system modernisation, risk reduction, and legacy decommissioning.
- Raise the engineering bar by mentoring senior engineers and emerging technical leaders.
- Take hands-on ownership of high-risk or high-impact technical work when it matters most.
- Champion operational excellence, including reliability, observability, incident learning, and cloud cost optimisation.
