Sr Principal Software Engineer - Full Stack

Description

We’re looking for a Full‑Stack Engineer who cares about building usable, reliable software that makes a real difference in healthcare. You’ll ship React/Vite web apps, build mobile apps with React Native or Swift/Kotlin when needed, and build the backend services behind them using Python, TypeScript, or Go with REST APIs. You’ll work closely with product, design, and research to turn ideas into prototypes and production features, and you’ll thoughtfully integrate AI services where they add value. We use Copilot and Cursor to speed up exploration and delivery, balanced with reviews, tests, and sound engineering judgment.

You’ll own features end‑to‑end from architecture and implementation to testing, deployment on OpenShift, and ongoing monitoring. If you like iterating quickly, learning in the open, and collaborating across disciplines, you’ll feel at home at BI X.

• 5+ years of professional experience in both front-end and back-end development, with a proven ability to integrate into seamless, high-quality products.


• Experience building responsive/adaptive web applications and mobile solutions with a user-centric approach.


• Profound experience in engineering practices such as code refactoring, design patterns, test-driven development, and continuous integration.

Core Competencies

• Strong proficiency in at least one modern front-end framework (e.g., React, Angular, Vue) and one back-end framework (e.g., Next.js, Django, Gin/Fiber, Spring).


• Extensive knowledge in building secure, scalable, and reliable software solutions, including experience with database design, API development, and cloud services (AWS & Azure).


• Familiarity with functional programming principles and modern software architecture standards.


• Expertise in software development testing and test automation, including unit testing, integration testing, and regression testing.


• Hands-on experience with version control systems and continuous development and deployment tools (e.g., Git, Jenkins, Docker, Kubernetes).


• Familiarity with container platforms, management systems, and development environments across QA, DEV, STAGING, and PROD phases.


• Knowledge of IT security, operations, and support best practices to ensure robust and secure solutions.


• Effective communication skills to articulate technical concepts clearly, facilitate discussions, and influence innovative solutions.


• Track record of mentoring and guiding junior engineers, fostering knowledge sharing, and promoting best practices within teams.


• Demonstrated thought leadership in driving innovation and contributing to the adoption of best practices across the full-stack development lifecycle.


• Strong ability to collaborate with cross-functional teams, ensuring alignment with business goals and user needs.

Desired Skills, Experience and Abilities
