.NET Tech Lead

About the role:

Are you a hands-on .NET engineer who has grown into technical leadership and wants to make a real difference in healthcare? We are looking for someone who can own the technical direction of a large .NET production system, keep quality high, and increasingly guide how the product evolve and adopts AI and agentic capabilities.

You will work on the .NET Core production of a large system alongside a strong and friendly team. You will spend most of your time on architecture, design, and coding, with a meaningful slice of team-lead responsibility — mentoring engineers, contributing to estimation and planning, and coordinating technical work across the back-end team. This is a tech lead role with *some* team lead responsibilities, not a pure management position.

Team: 5 back-end and data engineers, 1 front-end engineer, and 4 QA/BA.

Skills & Experience:

- Background in software engineering; a degree in Computer Science or a related technical discipline;

- 7+ years of commercial experience with .NET (strong .NET Core, ASP.NET Core);

- Proven track record as a technical owner — architecture, design decisions, and hands-on delivery on large, long-lived systems;

- 3+ years of leadership experience (tech lead, senior/mentor role, or similar) — comfortable guiding engineers with and without being a full-time people manager;

- Strong SQL skills (understanding of how SQL queries work in order to suggest consistent engineering solutions);

- Experience with large enterprise projects;

- In-depth understanding of Entity Framework / EF Core;

- Solid grasp of testing discipline — unit, integration, and performance testing as part of the development process;

- Self-starter who's able to see a piece of work through from A to Z;

- Upper-intermediate English or above.

Nice to have:

- Practical exposure to building or integrating AI/agentic features into production applications (LLM APIs, tool calling, RAG, or similar);

- Azure DevOps skills and CI/CD experience (Azure DevOps / GitHub Actions);

- Advanced front-end JS skills;

- Experience with JS frameworks (React / Angular / Ember, etc.);

- Experience in building SPAs;

- Experience in a regulated domain (healthcare, life sciences) and awareness of data-privacy/compliance considerations;

Responsibilities:

Technical leadership

- Own the technical design and architecture of back-end and AI/agentic components; make and document pragmatic build/buy and framework decisions;

- Stay hands-on: participate in design, development, and integration, and write production code for the most critical or complex parts of the system;

- Define, advocate, and enforce best practices and coding standards; lead code review and refactoring;

- Cover code with unit, integration, and performance tests, and build evaluation/testing approaches for AI-driven features;

- Investigate performance bottlenecks and drive code optimization proactively;

- Be a key contributor to new release deployments and the technical health of the delivery pipeline.

Team lead responsibilities 

- Mentor back-end engineers and help grow their .NET, SQL, and AI/agentic capabilities;

- Help distribute and coordinate back-end technical work; provide direction on how work should be built;

- Participate in grooming, estimation, and planning sessions; help plan and implement change requests;

- Support product owners and stakeholders in making sound technical decisions, and provide status updates on back-end development when needed;

- Collaborate with other team members and roles (front-end tech lead, TDM, BSA, architect, DevOps, DBAs, etc.) and troubleshoot issues as they arise.
