• Strong understanding of RESTful API design, layered architecture patterns, and ORM frameworks (NHibernate, EF Core, or similar)
• Solid SQL Server experience: complex queries, schema design, and performance tuning

Three philosophies we run by:

You’ll love this job if you already operate this way. If you don’t, we’re not the right fit for you.

Beyond that, you’ll thrive here if you’re a problem solver who prefers new problems to familiar formulas, comfortable in a small team that moves fast and wears many hats, and someone who ships.
