What you'll do

  • Partner with Engineering Directors to shape the technical and product direction of a collective, providing leadership across multiple squads (30–70+ engineers) and ensuring alignment with company-wide priorities

  • Partner closely with Product and Design leadership to define strategy, shape roadmaps, and make high-quality trade-offs that maximise business and customer impact across the collective
  • Mobilise teams across your collective 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, scalable designs across multiple teams and aligning local decisions with the broader system strategy
  • Set and uphold a high bar for technical excellence across the collective, driving improvements in quality, reliability and scalability, and fostering a culture where engineers hold each other to that standard
  • Proactively mentor, sponsor and develop senior engineers and future leaders, multiplying your impact by enabling others to operate at a higher level

What we're looking for

  • A track record of leading complex, high-impact systems and driving technical direction across multiple teams

  • Comfortable operating in ambiguous problem spaces, helping teams define direction and execute
  • Ability to influence and align senior stakeholders across engineering, product and beyond
  • Care about outcomes and impact, using data to guide decisions
  • Enjoy mentoring and raising the bar for other engineers
