Ready to shape the infrastructure that powers engineering at scale? As our Engineering Lead - Infrastructure Operations, you'll lead the platforms, tooling, and operations that keep our teams shipping safely and efficiently.

Our vision is to bring tech revolution to the financial services industry.

To support us in this mission, we are looking for an Engineering Lead - Infrastructure Operations to provide technical leadership for our AWS base platform operations team. You will help set direction for shared infrastructure and engineering operations - the production hosting, security perimeter, release pipelines, observability, and developer tooling that every engineering squad depends on to ship safely. This role includes Line Management responsibility for your team of 5-7 Engineers with the assistance of an assigned Engineering Manager.

The Role

• Delivery & technical leadership
  • Lead delivery of complex infrastructure and platform initiatives, managing dependencies and removing blockers.
  • Define and evolve the DevOps and infrastructure strategy, ownership model, and team boundaries.
  • Partner with engineering teams to deliver reliable, high-quality solutions aligned with business and regulatory requirements.
  • Collaborate with Engineering Leads to drive innovation, knowledge sharing, and continuous improvement.
  • Build strong relationships across product, engineering, security, and business stakeholders.
  • Enhance engineering practices across CI/CD, releases, incident management, and operational readiness.
  • Balance delivery priorities with technical debt, security requirements, and operational responsibilities.
  • Foster collaboration and alignment on shared platform and infrastructure initiatives.
• Infrastructure, reliability & security
  • Lead the evolution of deployment pipelines and system reliability across our monorepos and legacy platform (CircleCI, NX, Docker).
  • Guide AWS cloud strategy - hosting, networking, scalability, performance, and cost-efficiency across production environments.
  • Oversee Infrastructure as Code practices (e.g. Terraform) and ensure environments are consistent, auditable, and secure.
  • Shape monitoring, observability and alerting across the engineering organisation (e.g. Datadog, CloudWatch) so issues are detected and resolved before customers are impacted.
  • Lead incident management practices - on-call, triage, escalation, post-incident reviews, and runbook quality.
  • Champion security best practices - IAM, WAF, encryption, VPC configuration, and compliance with industry and regulatory standards.
  • Support capacity planning, cost optimisation, and production readiness for high-risk changes and coordinated cutovers.
• People & developer experience
  • Coach and mentor Operations Engineers, fostering technical leadership, delivery excellence, and strong operational practices.
  • Remain hands-on when needed, contributing to designs, code, configuration, and runbooks while empowering the team to take ownership.
  • Enhance developer experience through self-service tools, streamlined environments, improved documentation, and effective onboarding.
  • Support hiring efforts and help raise the bar for engineering talent across the team.

Qualifications

  • Ability to balance architecture, delivery, reliability, and business priorities.

  • Excellent stakeholder management and communication skills.
  • Proven people leader with a passion for coaching and developing engineers.
  • Strong strategic thinking and pragmatic decision-making.
  • Committed to building high-performing teams focused on customer and engineering outcomes.
  • Supporting a move across engineering to YBIYRI - “You build it, you run it” DevOps practices enabling teams to support anything they build in their domains.
  • Building FinOps frameworks and monitoring, focusing on cost optimization.
• Technical experience
  • Experience in Operations, DevSecOps, SRE, or Cloud Infrastructure roles in fast-growing, regulated environments.
  • Proven experience leading or acting as technical lead for a platform or operations team.
  • Strong AWS infrastructure experience, including cost optimisation, performance tuning, and production troubleshooting.
  • Proficiency with Infrastructure as Code tools such as OpenTofu, Terraform, or Cloud formation (OpenTofu preferred).
  • Expertise in observability - monitoring, logging, alerting, and APM (e.g. Datadog, Prometheus, Grafana, CloudWatch).
  • Solid understanding of Docker and containerisation technologies.
  • Deep CI/CD pipeline ownership and release governance in high-stakes environments.
  • Knowledge of AWS security best practices, including IAM, VPCs, WAF, and encryption standards.
