What the job involves

• We're hiring a Tech Lead for our brand new Payments squad, part of Saldo, our Billing and Payments Service
• Payments at tem works today, but it's a basic service. We're growing fast, and it needs to be built for the scale we're moving towards. You'll be the first tech lead in a squad that already has a senior engineer and three junior engineers, and you'll own the outcome of the squad's delivery and the standards it works to
• This is a hands-on role. You'll write design docs, review code, solve the hardest problems alongside the team, and set the technical direction for payments. The number you'll move is the cost of processing every pound that flows through tem. Your job is to bring it down, and keep it low as we scale
• In your first 12 months, you might:
• Set the architecture direction that takes payments from a functional service to one built for growth
• Define how the squad works, including the balance between speed, quality and resilience that payments demands
• Lift the quality and speed bar for the whole squad, senior and junior engineers alike
• Drive the technical blockers to delivery to resolution, so the squad's work reaches the people who depend on it
• Make payment accuracy and processing efficiency the levers that bring cost-to-process down
• You’ll report into the Service Manager for Saldo
• Own the outcome: Take responsibility for the squad's delivery and the standards it works to, so the team ships work we're proud of
• Lead from the front line: Write specs and design docs, give feedback on ADRs, review pull requests, and solve problems directly through code or workflows
• Set the payments architecture direction: Turn a genuinely ambiguous area into a clear technical strategy, without waiting for someone else to define the problem
• Cut the cost to process: Own payment accuracy and processing efficiency as the direct levers on cost-to-process
• Design how the squad works: Define the squad's operating model and set the pace, rather than waiting for a playbook
• Own the big picture: Manage sequencing and dependencies, diagnose why throughput isn’t improving, and make sure the squad's work is visible to stakeholders
• Build a high-performance team: Coach junior engineers while working the hardest problems alongside our senior engineer, and define what good looks like by working the details with the team
• Partner on people decisions: Flag promotion and hiring gaps to your manager, who keeps line management and performance conversations. Decisions on people are made jointly
