Responsibilities

  • Own the technical delivery of the platform, ensuring the team consistently ships high-quality, production-ready increments.

  • Lead estimation, sprint planning, and decomposition of technical work; proactively identify and manage technical risk, dependencies, and blockers.
  • Collaborate with the Delivery Manager and Product Owner to shape the backlog.
  • Contribute directly to the codebase, particularly on complex features, integration points, and technically critical components, setting the standard for others to follow.
  • Ensure alignment with the solution architecture function, clearly articulating technical constraints, risks, or emerging complexity with architectural implications, supported by evidence and proposed alternatives.
  • Ensure application of secure-by-design principles and validate and refine Figma wireframes.
  • Represent the team's technical work clearly and credibly to non-technical audiences.
  • Define and enforce CI/CD pipeline standards using Azure DevOps, including branch strategy, build validation, deployment gates, and environment promotion.

Qualifications

  • Proven experience as a technical lead on a complex, multi-service platform, with direct responsibility for technical delivery quality and team output.
  • Extensive C# and ASP.NET Core experience, including RESTful APIs, dependency injection, domain modelling, integration patterns, and performance considerations.
  • Experience with Entity Framework Core code‑first migrations and data modelling.
  • Strong front‑end engineering skills in React and TypeScript, including component architecture, state management, and integration with REST/SignalR backends.
  • Solid understanding of event‑driven architectures.
  • Hands‑on experience with PostgreSQL or comparable relational databases.
  • Experience with API and application security.
  • Practical knowledge of Python, including frameworks such as FastAPI.
  • Practical knowledge of the Java stack.
  • Proven experience with deploying and managing Azure cloud services.
  • Experience deploying and operating containerised workloads in Kubernetes.
  • Experience writing and maintaining CI/CD pipelines in Azure DevOps.
  • Engagement with novel technology, such as AI, to maximise output.
  • Experience collaborating with UX designers - reviewing wireframes and providing technical feedback.
  • Agile delivery experience, including sprint planning, backlog refinement, estimation, and working productively with a Product Owner and Delivery Manager.
  • Experience integrating with payment platforms (e.g. Stripe) and electronic signature services (e.g. DocuSign).
  • Experience developing solutions within a regulated industry.
  • Communicate effectively and share thoughts and ideas through methods appropriate to the audience.

Benefits

  • 30 days annual leave (plus bank holidays).
  • Private medical and dental cover.
