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., * 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)., * 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. ## Description 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., * 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. ## Related Videos - [Recruitment Reinvented: Bold strategies and the $10K signing incentive](https://www.wearedevelopers.com/videos/1068-recruitment-reinvented-bold-strategies-and-the-10k-signing-incentive) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Reducing LLM Calls with Vector Search Patterns - Raphael De Lio (Redis)](https://www.wearedevelopers.com/videos/1714-reducing-llm-calls-with-vector-search-patterns-raphael-de-lio-redis) - [Streaming AI Responses in Real-Time with SSE in Next.js & NestJS](https://www.wearedevelopers.com/videos/1630-streaming-ai-responses-in-real-time-with-sse-in-next-js-nestjs) - [Docker build without Docker](https://www.wearedevelopers.com/videos/100114-docker-build-without-docker) ## Related Articles - [How to Answer the Interview Question: “Why Do You Want to Be a Software Engineer?”](https://www.wearedevelopers.com/magazine/392-how-to-answer-the-interview-question-why-do-you-want-to-be-a-software-engineer) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again)
