Backend Software Engineer

About us Corner Health is an early-stage technology company building the operating system for independent primary care. We give Nurse Practitioners (NPs) everything they need to start and run their own practices — from billing and insurance infrastructure to AI-powered workflow automation. We’re positioned to be the fastest growing in-person primary care company ever. Corner Health was co-founded by Lava Sunder and Anne Gifford and has raised $32.5m backed by Oak HC/FT, First Round Capital, Homebrew, Zigg Capital, Wischoff Ventures, as well as the founders of DoorDash, Commure, Grow Therapy, Kindred, Culdesac & more. About the Role We're looking for a senior backend engineer to help build and scale the core infrastructure behind Corner's practice operating system. Today we process thousands of appointments per week across a growing network of independent practices. Behind each appointment is a web of interconnected systems — insurance eligibility checks, patient intake orchestration, claims submission and lifecycle management, payment reconciliation, and provider payouts. These workflows involve coordinating across EHRs, clearinghouses, and payment processors, each with their own quirks and failure modes. Some of the problems you'd work on: Intake orchestration : Our pre-appointment flow handles patient texting, intake form completion, and follow-up cadences — with edge cases for same-day and next-day bookings where the standard timing doesn't apply. This is a real state machine problem with a lot of nuance. Claims and billing infrastructure : Building reliable, high-throughput services for the full claims lifecycle — from eligibility verification through submission, adjudication tracking, and remittance processing. Analytics and observability : Designing our data layer so we can actually measure what matters — tracking KPIs like insurance failure rates, surfacing trends across practices, and making sure the backend is shaped in a way that makes improvement measurable. We need someone who thinks about data shape and accessibility as a first‑class concern. Workflow automation : Designing and extending orchestrated, multi‑step backend workflows that reduce administrative burden for providers and improve the accuracy and speed of reimbursements. You’ll work closely with product and operations to translate complex, real‑world healthcare workflows into scalable, intelligent infrastructure. As one of our first engineering hires, you’ll work directly with the co‑founders, have real ownership over the product, and help shape both the codebase and the culture. What you’re like You are hard‑working, kind, curious, and intelligent. You have a high degree of autonomy and the ability to scale from 10 to 1000. You are excited about working in a dynamic, constantly changing environment. You are pragmatic about incorporating agents and LLMs in your work. You have 4+ years of backend engineering experience, ideally with TypeScript, Node.js, and SQL‑heavy environments (familiarity with BigQuery, GraphQL, or workflow orchestration tools like Inngest is a plus). What would set you apart You’re excited by the idea of creating more independent medical providers. You are product‑first → you’re familiar with driving end to end execution, including QAing your work. You’re excited about workflow automation & designing systems from first principles. You have experience with data warehousing and API design. You enjoy working in‑person (our office is in Santa Monica, CA); you either live in LA or are excited to move to LA. You have healthcare compliance experience (a plus but not must‑have). Benefits Competitive salary & equity compensation. Top‑tier health and dental. Health & wellness stipend. Eligible to participate in company‑sponsored 401(k) plan. What We’re Like You’re joining an early‑stage company - it’s important to learn more about what we’re like! Here are some of our engineering principles — they are all important, but we’re excited for this hire to contribute to them as well. Ship early, ship often We prioritize frequent deployments to maintain momentum and learn quickly. Small PRs are faster to review, easier to roll back, and create positive feedback loops. We use feature flags for gradual rollouts and invest in robust CI/CD with comprehensive testing. Merging to main should be routine, not stressful. Choose boring technologies (mostly) We default to established, battle‑tested technologies with strong ecosystem support and good LLM integration (Prisma, WorkOS, Node.js, etc). We have limited innovation tokens—spend them on problems that differentiate us or bring genuine joy to the team. Strong foundations let us move fast and experiment at the edges where it matters, whether that's core product features or fun internal tooling. Work with the garage door up We build transparency into our development process. PRs are reviewed by the team—not just for code quality, but to share knowledge and create visibility into what we're building. We document decisions, share work‑in‑progress updates, and make our process discoverable. This enables early feedback, prevents duplicate work, and helps everyone learn from each other's approaches. Great ideas emerge from collision, not isolation. Code as documentation In the LLM era, clear code, consistent patterns, and well‑ documented systems are force multipliers. We document our patterns, conventions, and common workflows. We automate repetitive tasks through scripting and templates. When AI tools repeatedly make the same mistakes, we update our rules and guidelines. Enforcing consistency today saves hours tomorrow. Own your code LLMs are powerful tools that can accelerate development, but every line of code you submit should be code you understand, can defend, and have proven to work. When you open a PR, you're putting your name on that solution—be ready to explain how it works, why you chose that approach, and what trade‑offs you considered. Use AI to explore ideas and generate starting points, but take the time to understand, refine, and truly own what you're shipping. We build trust through craftsmanship, not through volume. We’re a small team with high ownership and high autonomy. AI tools let us punch way above our weight, but we care deeply about the quality of what we ship — no vibe coding, no slop. You’ll spend your days building, not waiting on approvals or sitting in meetings. Lastly - one of our team values is “Life is short - it’s OK to laugh”. Whether it’s late-night team dinners, mini golf, or just jamming on new product ideas for our customers - we work hard and have fun doing it.
