Be hands-on in both coding and architecture, leading from the front.

Partner closely with Engineering and Product leadership to shape roadmaps and make high-quality trade-offs that maximise business and customer impact.

Mobilise the team around high-impact problems, creating clarity, alignment and momentum, injecting urgency when needed, or slowing things down to ensure safety and long-term sustainability.

Lead and influence architectural direction for the most complex systems, ensuring cohesive and scalable designs

Set and uphold a high bar for technical excellence across the team, driving improvements in quality, readability and scalability, and fostering a culture where engineers hold each other to that standard.

Proactively mentor, sponsor and develop senior engineers, multiplying your impact by enabling others to operate at a higher level.

Leading and influencing engineers in the team without direct authority – through code, design reviews and technical mentorship

Champion the adoption of AI-assisted development practices and tools across the team, helping raise the bar on engineering velocity and code qual

Demonstrable experience operating at staff or principal level

Deep backend engineering expertise with a track record of designing and building distributed systems at scale

Solid understanding of Core account infrastructure and geolocation flows

Strong written and verbal communication; you can make complex technical decisions legible to non-technical stakeholders

Hands-on experience using AI-assisted development tools (e.g. GitHub Copilot, Claude Code, Cursor) in your day-to-day workflow, with a genuine enthusiasm for how AI is changing software engineering, and a track record of championing AI-assisted practices — in software development, system design, testing, operations, or troubleshooting — while understanding their limitations and trade-offs.
