Very strong object-oriented design skills with proven track record of well-engineered design.
Proven skill writing clean, readable, reusable C# libraries and familiarity with a wide variety of design and architectural patterns.
Fluent in a broad swath of C#, including memory storage, Generics with Type Constraints, Custom Events, Custom Attributes, Generic Delegates, Multi-threading, Reflection, Extension Methods, lambda expressions, fluent with the primary file system operation classes, understands the garbage collection architecture and techniques for monitoring.
Demonstrated experience building and supporting hosted client server applications, including strong skills with relational databases (Entity Framework, LINQ) and source control (Git preferred).
Proven engineering discipline with unit testing, effective collaboration with QA, and strong estimation and organizational skills to deliver reliably.
Commitment to collaborative problem solving, thoughtful design, and delivering quality products, with the ability to partner effectively across business and technology teams, ramp quickly on complex architectures, contribute at both the architectural and coding levels, and mentor peers and junior team members.

We’re Even More Excited If You Have:

Experience building web applications or internal tools with React
Experience with Functions-as-a-Service (FaaS) – especially Azure Functions
Experience with automated deployment tools like Azure DevOps Pipelines
Experience using NoSQL databases
Knowledge of caching solutions (e.g. Redis)
