Staff Software Engineer, Growth

The posting, as Hinge Health wrote it

THE ROLE

We're looking for a Staff Engineer to join our Referrals team and help us build a unified Incentive Platform. The domain that tracks eligibility, entitlement, and fulfillment state for incentive rewards. Our team owns and operates this platform: the system of record for what a member is owed and when.

This is a high-ownership, systems-first role within the team. You'll set technical direction for a platform that's mid-consolidation. Carving a clean domain boundary out of an existing service, closing known correctness gaps, and negotiating the contracts that other teams build against. You'll work closely with product and data science, and have a direct line to business outcomes like referral conversion and cost-per-acquisition.

WHAT YOU’LL DO

• Own the technical direction for the Incentive Platform. Carve a dedicated domain out of its current home, with enforced boundaries and a facade other services call instead of reaching into internals.
• Generalize eligibility and entitlement logic into real, owned APIs, replacing duplicated caps and ad hoc scripts with a single source of truth for what a member has earned and is owed.
• Run production data migrations. Dual-write, backfill, cutover on a system with financial and compliance stakes, where correctness during the transition matters as much as the end state.
• Negotiate and build the technical contract with Fulfillment: idempotent order creation, failure handling, real-time inventory, and reserve/release semantics. You're the technical counterparty other teams negotiate with, not just an implementer of their asks.
• Find and close correctness gaps in the current system. Places where real dollar-value entitlements are miscounted, under-specified, or rely on an undocumented assumption.
• 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.
• Mentor engineers on the team, growing their judgment on architecture and cross-team tradeoffs over time.
• 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

• Domain modeling under legacy constraints - You've carved a bounded context out of a service with accreted responsibilities, without a rewrite, while it kept shipping.
• Production migration experience - You've run a dual-write/backfill/cutover on a real data model, ideally with financial or compliance stakes where getting it wrong is expensive.
• 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 leaders
