Senior Engineer - Application and Product Systems (ASP.NET)

At WISEcode, we're a well-funded, dynamic startup. WISEcode makes personalized nutrition a reality based on the facts – what truly is in our food — and marries this data with your preferences. Powered by AI and the world’s best food and nutrition database, WISEcode embraces the fact that we are all different, have different dietary needs, objectives, and preferences, and should not be at the mercy of market spin or “expert” opinion. Every one of us should have the information we need to make the best decisions for ourselves.

The Opportunity

We are hiring Senior ASP. NET Engineers to work on Code Builder, one of WISEcode’s most strategic and technically interesting products.

Code Builder is a production-grade platform that 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 in ASP.NET Blazor.

This is not a greenfield demo and not a thin UI over APIs. It is a serious 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 a Senior Software Engineer, you will be a hands-on contributor to Code Builder and adjacent platform components, with a strong focus on ASP.NET and 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 to get 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 evolving rich, data-driven Blazor UIs that power Code Builder’s workflows
• Implementing features that combine deterministic nutrition logic with AI-assisted insights
• Working with complex domain models representing foods, ingredients, nutrients, processing, and health signals  
• Extending ASP.NET APIs 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 enjoy thinking through real-world complexity, not abstract toy problems.
