Staff Software Engineer, CV UX

THE OPPORTUNITY

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.

WHAT YOU'LL ACCOMPLISH

In your first 3 months:

• 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.

In your first 6 months:

• 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.

In your first year:

• 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.

WHO YOU ARE

• A Force Multiplier: You don't just ship great code — you improve the team's overall architecture, developer tooling, and practices, making everyone around you more effective.

• A Learn-it-all: You stay at the forefront of mobile development, computer vision UX, and AI-powered developer tools. You bring "only-now-possible" ideas to the team and turn them into shipped capabilities.

• Accountable: You take owner-operator pride in your code in production. You meet commitments, estimate well, and don't stop before solving the last 10–20% where the messy edge cases lie.

• A Trust Builder: You communicate effectively across engineering, product, design, and data science teams to align on shared goals. You explain complex technical concepts to non-technical stakeholders in a way that is understandable and not condescending.

• Hands-On Leader: You lead at all levels — architecting systems and writing code, reviewing PRs and mentoring engineers, thinking quarters ahead and unblocking teammates today.

BASIC QUALIFICATIONS

• 8+ years of 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

• 2+ years of experience with cloud platforms (e.g., AWS EC2, Lambda, S3, RDS) and containerization tools (e.g., Docker, Kubernetes)

• 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

PREFERRED QUALIFICATIONS

• 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

• Proficiency in both English and French is an asset
