This is a role that includes Line Management responsibility for your team of 5-7 Engineers with the assistance of an assigned Engineering Manager.
The Role Technical Leadership Lead the evolution of backend architecture across our PHP platform, Go services, and GraphQL/API layers - balancing delivery speed with long-term maintainability
Guide API and domain design standards - clear service boundaries, consistent contracts, and pragmatic integration between modern services and legacy systems
Shape event-driven and integration patterns so teams can build independently without breaking cross-squad journeys
Champion automated testing, observability, and production readiness for backend services - PHPUnit, Go tests, Datadog, and safe release practices
Oversee database and schema evolution practices - migrations, data integrity, and performance - in partnership with platform and infrastructure teams
Lead incident response for backend-owned systems - triage, escalation, post-incident reviews, and runbook quality
Mentor engineers on PHP (Yii/Yii2), Go, Security, Performance and Optimisation - raising the bar through design review and hands-on contribution when needed
Support production readiness for high-risk changes - coordinated cutovers, rollouts, and cross-team dependencies at the legacy/modern boundary
Delivery Leadership Lead delivery of complex, multi-team initiatives by managing dependencies, resources, and blockers
Define and drive technical strategy, improving engineering practices and delivery processes
Build strong partnerships across product, engineering, security, and business teams
Keep teams focused on priorities while balancing technical debt and operational needs
Drive collaboration across teams and lead cross-engineering initiatives with fellow Engineering Leads.

Strategic and tactical decision-making abilities
Commitment to creating an empowering team environment that prioritises customer experience and engineering productivity
Technical experience
Proven experience as a team lead or technical lead in fast-growing, regulated environments (fintech, pensions, banking, or insurance)
Deep expertise in at least one engineering discipline relevant to your squad - backend, frontend, mobile, quality, or platform operations - with solid breadth across design, build, test, and run Track record of owning production systems end-to-end: implementation, rollout, monitoring, incident response, and follow-up Experience leading technical delivery on complex, ambiguous initiatives involving multiple engineers, dependencies, or teams
Strong architectural judgement - evaluating trade-offs, setting direction, and aligning others on pragmatic, maintainable solutions
Expertise in automated testing, CI/CD, and safe release practices in high-stakes production environments
Familiarity with observability and operational excellence - monitoring, alerting, runbooks, and blameless learning from incidents
Understanding of security, compliance, and non-functional requirements in regulated financial services
Comfortable working across modern and legacy systems - evolving the platform incrementally rather than through unnecessary rewrites
