Senior Engineer - Application and Product (ASP.NET)

The Opportunity We are hiringSenior ASP. NET Engineersto work onCode Builder, one of WISEcode’s most strategic and technically interesting products. Code Builder is aproduction-grade platformthat allows complex nutrition logic — rules, formulas, thresholds, transformations, and AI-assisted interpretation — to be assembled, executed, and evolved across hundreds of thousands of real foods. It sits at the intersection of: •Large-scale, proprietary nutrition data•Deterministic computation and scoring pipelines•AI-assisted data acquisition and interpretation•Rich, stateful, data-intensive user interfaces built inASP.NETBlazor. This is not a greenfield demo and not a thin UI over APIs. It is aserious system, already in active use, with real architectural depth and room to grow.We are looking for senior engineers who enjoy stepping into sophisticated systems, understanding how they work, and making them better. About the Role As aSenior Software Engineer, you will be a hands-on contributor to Code Builder and adjacent platform components, with a strong focus onASP.NETand Blazor. You will work in a mature, evolving codebase where: •Architectural patterns already exist•Data models are deep and nuanced•Correctness matters•Performance matters•Changes must be thoughtful, not reckless Senior Engineers at WISEcode are expected toget productive quickly, navigate complexity confidently, and deliver high-quality features without needing constant direction. You will collaborate closely with Principal Engineers who define system direction, while owning meaningful pieces of execution yourself. What You’ll Work On •Building and evolvingrich, data-driven Blazor UIsthat power Code Builder’s workflows•Implementing features that combinedeterministic nutrition logicwithAI-assisted insights• Workingwith complex domain models representing foods, ingredients, nutrients, processing, and healthsignals•ExtendingASP.NETAPIs and services that execute and orchestrate nutrition computations at scale•Integrating AI outputs responsibly into user-facing and internal workflows•Navigating and improving a large, long-lived production codebase•Debugging and optimizing behavior across UI, application logic, and database boundaries This is a role for engineers who enjoythinking through real-world complexity, not abstract toy problems. What Success Looks Like Within the first few months, you are: •Comfortable navigating a large, sophisticated codebase•Shipping production features independently•Confidently working in Blazor without friction•Making sound decisions about when to refactor vs. extend existing systems•Contributing to a shared understanding of how Code Builder works and how it should evolve Required Qualifications •6–10+ years of professional software development experience•Strong, hands-on experience withASP.NETand modernC#•Production experience withASP.NETBlazor(Server or WebAssembly)Experience working inlarge, long-lived codebases•Solid understanding of application architecture and layered systems•Experience with relational databases, ideallyPostgres•Familiarity withEntity Framework Coreor similar ORMs•Comfort reasoning across UI, API, and database layers•Ability to work independently while collaborating effectively with senior technical peers•Pragmatic engineering judgment — you value correctness, clarity, and maintainability Nice to Have •Experience working with complex domain models or rule-based systems•Exposure to AI/ML-powered features or data pipelines•Experience with performance tuning or profiling inASP.NET/ Blazor•Background in data-intensive or analytics-heavy products•Enterprise authentication and authorization systems•Microsoft Semantic Kernel, MCP Server SDK,Agent Framework Why This Is a Great Place for a Senior Engineer •Work on amission-critical productbuilt inASP.NETBlazor, not a side UI•Solve real problems at the intersection ofAI, data, and deterministic systems•Learn how large-scale, high-stakes computation platforms are designed and evolved•Collaborate with Principal Engineers who care deeply about architecture and clarity•Build systems that help make nutrition — and health — more transparent and understandable•Competitive compensation, benefits, and clear paths for growth WISEcode is an equal opportunity employer.
