About The Position

Over 1.7 billion people worldwide live with musculoskeletal pain — and Hinge Health is on a mission to help them move beyond it. Our TrueMotion computer vision technology turns everyday mobile devices into powerful motion-tracking tools, giving members real-time feedback and guidance as they work through personalized exercise therapy. The CV User Experience team is responsible for making that magic feel effortless: building deeply interactive, TrueMotion-driven features that monitor movement, coach performance, and track recovery progress.
We're looking for a Staff Software Engineer to serve as the technical leader for this team — someone who can architect end-to-end systems across mobile and backend, tackle complex scaling challenges, and raise the bar on engineering quality. If you're passionate about building high-quality software that directly improves people's health outcomes, this is your role.

• 8+ years of non-internship, full-time professional software engineering experience
• 3+ years of experience building and shipping mobile applications
• 3+ years of experience with backend technologies such as TypeScript, Node.js, NestJS, or GraphQL

• Experience working in distributed systems and microservices architectures
• Hands-on experience with generative AI tools to accelerate development workflows, improve code quality, and streamline debugging

Nice To Haves

• 3+ years of experience building and shipping mobile applications using React Native
• Experience with event-driven architectures and tools such as Apache Kafka
• Proficiency with observability tools such as Datadog and Sentry
• Strong understanding of system design principles, mobile application architecture, and CI/CD pipelines
• Experience with computer vision–driven user experiences on mobile platforms
• Demonstrated track record of mentoring engineers and leading architectural discussions across teams

Responsibilities

• Ramp into the CV User Experience stack (React Native, TypeScript, NestJS, GraphQL, AWS) and build relationships with product managers, designers, data scientists, and computer vision scientists.
• Deliver your first end-to-end feature while auditing the current architecture for scaling and performance bottlenecks.
• Own and lead architectural discussions for TrueMotion-driven experiences, proactively identifying challenges and proposing innovative solutions to complex mobile and full-stack engineering problems.
• Establish stronger system observability using Datadog and Sentry, improving monitoring, logging, and error tracking across the full stack.
• Profile systems to stay ahead of scaling and performance bottlenecks, ensuring a fast, responsive mobile experience for users.
• Act as the primary technical leader for the team's architecture — designing robust, end-to-end solutions including performant APIs, mobile application architecture, and data models that are the foundation for TrueMotion's next generation.
• Mentor engineers and promote a culture of technical excellence and continuous improvement through thoughtful code reviews, design discussions, and knowledge sharing.
• Every quarter, identify, propose, and execute a significant upgrade or innovative change to the team's workflow, tooling, or architecture.
