Role Overview

We're partnered on an exclusive Tech Lead search with an established, market-leading business operating mission-critical devices deployed at national scale in a regulated, high-volume payments environment.

This is a genuine leadership seat, not a title in waiting. You'll lead a single delivery team of around 5 to 8 engineers (including embedded QA), own its delivery end to end, and grow every person in it. You'll stay technically credible in your domain, run the ceremonies that actually produce outcomes, and represent your team honestly upward. If you want deep technical work with zero people accountability, this isn't the one - and that's the point.

Key Responsibilities

• Own your team's delivery: sprint and quarterly commitments, with risk surfaced early and honestly
• Break complex features into team-sized work and run standups, planning, and retrospectives that produce real outcomes
• Manage capacity properly - explicit space for tech debt, not an invisible tax
• Lead people: regular 1-2-1s, honest development conversations, and hiring against a competency matrix
• Own operational health: your team's on-call rota, incidents in your domain owned to resolution
• Make sound day-to-day technical calls and capture the significant ones as ADRs
• Partner closely with Product on what your team is committing to and why
• Escalate cross-team risk and capacity conflicts before they become a miss

Nice to Have

• Payments exposure: EMV, contactless, and an appreciation of the compliance surface (PCI-DSS, key management)
• Matrix-organisation experience - adopting standards set by roles you don't manage
• Azure DevOps for backlog and pipeline tooling
• Regulated-environment experience (financial services, transport, healthcare)
• Rust and/or Python, or a genuine willingness to learn them
• Leading a team through organisational or structural change without stalling delivery

If you tick every box above, hold ILR or a British passport, and can start ASAP, we'd love to hear from you.
