RSSB are now seeking an experienced Principal Technical Lead to drive the hands-on technical delivery of a new greenfield industry services platform. This is an exciting delivery-focused role for a senior engineer who can lead by doing: making confident technical decisions, setting the quality bar, and guiding a multi-disciplinary sprint team to build and ship a complex system.
As Principal Technical Lead, you will deliver a suite of capabilities including workflow automation, document management, scheduling optimisation, real-time notifications, and integrated reporting. A range of internal and external systems including CRM, ERP, payment, and document signing services will be integrated.
Responsibilities

- Ensure engineering standards are followed across the team: coding conventions, API design, security practices, and code review processes.
- 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.
