The role

We are pursuing a multi-year State of Michigan contract to maintain, support and enhance five public-health applications used for lead-poisoning surveillance, lead-abatement certification, toxicology and environmental sampling.

- Estimate, design and deliver State-requested enhancements through a formal change-control process

- Keep code, documentation and deployments aligned with State security standards (NIST controls, MFA, encryption) and WCAG accessibility

- Mentor developers, review code and own release quality

Must have

- 5+ years as Technical Lead on an application-support or development project of similar size and complexity

- 5+ years of hands-on work in .NET and SQL Server environments (C#, ASP.NET, T-SQL, stored procedures, query tuning)

- Experience supporting production systems under a service-level agreement

- Excellent communication and organization skills; comfortable presenting to government stakeholders

- Must live and work in the United States

Nice to have

- .NET 8 / ASP.NET Core and SQL Server 2022
