Staff Software Engineer, Growth

The Role

We’re looking for a Staff Engineer to join our Growth team and scale the programs that bring new members into Hinge Health. This team owns our member-to-member referral program end-to-end — the incentive mechanics, referral flows, and personalization systems that motivate existing members to refer colleagues and family members.

This is a high-ownership, full-stack role. You’ll set technical direction, work closely with product and data science, and have a direct line to business outcomes like referral conversion, cost-per-acquisition, and incremental bookings.

What You’ll Do

• Own the technical direction and roadmap for the member referral platform across the full stack — from frontend experiences to backend services and data pipelines.

• Scale incentive and referral systems to handle growing member volume and complexity without degrading conversion or user experience.

• Integrate ML model outputs (for example, propensity scores, personalized offers, and targeting signals) into referral surfaces to improve effectiveness.

• Design, instrument, and analyze A/B experiments; work with data science to close the feedback loop between model outputs and product outcomes.

• Partner with product, design, and analytics to define what to build and why, balancing short-term wins with long-term platform leverage.

• Raise the engineering bar by driving code quality, system design standards, observability, and technical decision-making on the team.

• Participate in the team’s weekly on-call rotation, helping ensure the reliability and timely support of the systems we build.

What We’re Looking For

• Incentive & growth experience — a track record of designing or evolving systems that measurably shift user behavior through incentives, rewards, or social mechanics. Domain background matters less than demonstrated growth impact.

• Personalization at scale — experience operationalizing ML model pipelines, model serving, A/B testing infrastructure, and feedback loops that connect model performance to product outcomes.

• Full-stack depth — strong skills across technologies such as React, React Native, TypeScript, NestJS, GraphQL, Node.js, relational and non-relational databases, Docker, Kubernetes, AWS, and Redis. We don’t expect a perfect match on every technology, but you should be fluent in most.

• Staff-level leadership — you’ve set technical direction for a team, influenced cross-functional roadmaps, and made architectural decisions that have held up over time.

Basic Qualifications

• Bachelor’s degree (or foreign equivalent) in Computer Science, Engineering, or a related technical field.

• 4+ years of professional software engineering experience, including meaningful time working on production systems at scale.

• Hands-on experience building and operating full-stack applications (for example, using React/React Native on the frontend and Node.js/TypeScript or similar on the backend).

Preferred Qualifications

• Experience designing and scaling incentive, rewards, or referral systems that drive measurable user and business outcomes.

• Experience integrating ML models into production systems (for example, model serving, feature pipelines, experimentation, and feedback loops).

• Depth with modern web and service technologies such as React, React Native, TypeScript, NestJS, GraphQL, Node.js, relational and non-relational databases, Docker, Kubernetes, AWS, and Redis.

• Proven experience setting technical direction for a team, owning architectural decisions, and driving high-quality execution in partnership with product and data science.

• Experience with experimentation platforms, A/B testing frameworks, or ML feature stores.

• Prior work at a consumer growth-focused company (for example, e-commerce, marketplaces, or consumer apps) and/or experience with viral or referral growth mechanics.

• Experience working in healthcare or other regulated-data environments.

Why This Role

• High ownership, low bureaucracy — this team moves quickly and ships iteratively while maintaining high technical standards.

• Direct, measurable impact — your work has a clear line of sight to how many people access MSK care through Hinge Health.

• Greenfield technical challenges — including scaling referral infrastructure, integrating personalization, and evolving experimentation capabilities as member volume grows.

• Deep collaboration — you’ll work closely with strong data science, product, and marketing partners who are embedded with the team.

Hinge Health Hybrid Model

We believe that remote work and in-person work have their own advantages and disadvantages, and we want to be able to leverage the best of both worlds. Employees in hybrid roles are required to be in the office 3 days/week.
