Employment: Full-time

Description:

Stack Builders is an international software consultancy that helps globally admired companies build exceptional software. We're looking for a collaborative Senior Full-Stack Python Engineer to join our team and help a US healthcare benefits administrator modernize its core systems. You'll build new applications from the ground up with Django and React on Azure, and integrate them with a commercial claims administration platform and an enterprise data lakehouse. Learn more about us here!

This role is ideal for engineers who enjoy owning a feature end-to-end, from the data model and API to the screen a business user works in, and who are comfortable turning complex business rules into well-tested code.

You'll work with the client's IT and business teams and other Stack Builders engineers on several related projects running in parallel, in an environment that handles protected health information and where correctness matters.

What You'll Do

• Build web applications end-to-end with Django, Django REST Framework, and React.
• Design and document versioned REST APIs that other teams and systems build against.
• Implement calculation-heavy business logic, such as insurance rating and renewal rules, and back it with thorough automated tests.
• Integrate with third-party APIs and enterprise data platforms, handling rate limits, retries, and audit trails.
• Contribute to architecture decisions across projects that share services and conventions.
• Work directly with client stakeholders to clarify requirements and validate results.
