• Partnering with product to break down and deliver meaningful work

• Experience working with serverless architectures (AWS, Lambda, APIs)
• Track record of building and scaling production systems
• Solid testing mindset (unit + end-to-end)
• Comfortable working in environments where security and reliability matter
• Someone who enjoys collaborating, mentoring, and raising the bar

Package

• Up to £110k + meaningful equity
• 9% employer pension
• Private medical, dental, and life assurance
• Annual learning budget + home setup allowance
• Enhanced family leave
