Hinge Health blends licensed care providers with AI solutions and medical-grade hardware to deliver a complete experience that improves user health.

Responsibilities

• First 3 months:
  • Contribute to defining the GI product line from scratch.
  • Deliver at least 1 large project introducing new product capabilities, often acting as a maintainer for key code repositories.
  • Break down complex problems into manageable tasks, ensuring steady and predictable delivery while identifying and resolving root causes of incidents.
  • Exhibit strong user and business judgment, grounding decisions in customer needs and business priorities.
  • Communicate technical ideas clearly to both technical and non-technical partners, and document solutions for future reference.
• First 6 months:
  • Implement key functionalities of the new GI product, delivering high-quality, bug-free, high-performance software on a tight schedule.
  • Drive 3+ high-complexity projects from the roadmap as their engineering leader.
  • Implement engineering best practices such as CI/CD, automated testing, monitoring, or client performance across the code repo you support.
  • Proactively improve the maintainability, availability, and performance of the team’s features, and contribute to the team’s overall architecture and developer tooling.
  • Integrate and leverage AI technologies to automate processes and enhance product features.
  • Mentor and support junior engineers through code reviews and real-time pairing.
• First year:
  • Launch the new product and iterate based on real member feedback post-launch.
  • Drive cross-team initiatives to improve the end-to-end journey for GI end users.
  • Continuously raise engineering standards (testing, observability, reliability, accessibility, performance) and help scale the team’s impact as the product and membership grow.

Requirements

• A minimum Bachelor’s Degree (or equivalent) in Computer Science, Engineering, or a related technical field.
• A minimum of 3+ years of non-internship full-time professional software development experience.
• 4+ years of experience with at least one software programming language.
• 4+ years of experience in the full software development life cycle.
• Experience delivering large software projects or features in a production environment.
• Proficiency in at least one modern programming language (e.g., Python, Java, JavaScript).

Qualifications

Preferred:

• Technologies: Experience building in large React Native codebases, TypeScript/Node.js & Go backends, GraphQL, AWS services (e.g., Lambda, SQS, SNS, SageMaker), tooling for client performance, render optimization, devops, and app architecture patterns.
• Product Integration mindset: History operating a product surface that integrates across multiple platforms owned by different teams.
• Track record of running experiments (e.g., A/B tests or multivariate tests) on core product surfaces and using results to drive roadmap decisions.
• Strong proficiency with TypeScript/JavaScript, React Native, and modern mobile development tooling; familiarity with backend services (e.g., Node/TypeScript, GraphQL, or similar) is a plus.
• Demonstrated ability to mentor and grow other engineers through code reviews, design collaboration, and technical guidance.
• Comfort collaborating with product, design, and data/analytics partners to define metrics, interpret results, and refine experiences.
• Experience developing consumer-facing apps used by millions/billions of users.
• Experience working within healthcare (HIPAA) or other highly regulated domains involving sensitive member data.

Skills

• 0->1 Builder: Track record of building brand-new products from scratch.
• AI-Driven development: Experience using the latest AI software development techniques (e.g., teams of AI Agents) and continuously seeking new AI techniques to improve productivity.
• Hands-on engineer: Ability to read and write code across the tech stack (e.g., React Native, BFF/full-stack web, GraphQL, AI Agents, Computer Vision, Medical Device Integration) and use that fluency to coach, review, and set technical direction.
• Experiment-driven operator: Ability to think in terms of hypotheses, sample sizes, and decision rules, and run a dense A/B experimentation roadmap without sacrificing quality.
• Team mentor and collaborator: Enjoy leveling up a strong but more junior team through pairing, code reviews, design discussions, and clear written communication.
• Owner mindset: Think in terms of systems and business impact, not just tickets—comfortable taking a problem from idea through launch, measurement, and iteration.
• Inclusive team builder: Create clear expectations, give direct feedback, and foster a culture where engineers can do the best work of their careers.
