Job description

Senior Platform Engineer

Location: Hybrid

Team: Platform Engineering

Reports to: Senior Director

Type: Full-time

About the Role

We're building a next-generation Healthcare App Platform - a flexible foundation that enables rapid development of high-quality, customizable healthcare applications. This is not your typical role - we're building the platform that builds the products.

Healthcare apps share a lot of the same DNA - appointments, care plans, status tracking, forms, communication, reporting. The challenge is in allowing for workflow customization without sacrificing developer productivity or runtime performance.

We're looking for Senior Engineers to help define and build the service-oriented architecture that powers this platform, in collaboration with in-house SMEs, product, and design partners.

What You'll Be Doing

  • Build Domain-Agnostic Services: Design, build, and maintain highly reliable, scalable, and shared backend services, APIs, and libraries used across multiple product domains.
  • Develop Platform UIs: Build clean, intuitive front-end interfaces (e.g., internal dashboards, developer portals, configuration hubs) that allow product teams to self-serve, monitor, and manage their usage of platform services.
  • Champion Developer Experience (DevEx): Treat internal developers as your primary customers. Actively identify friction points in the engineering lifecycle and build tools or services to eliminate them.
  • Standardize and Scale: Create paved roads and golden paths for product engineers. Ensure that the easiest way to build at Chorus is also the most secure, scalable, and compliant way.
  • Cross-Team Collaboration: Partner closely with product engineering teams to understand their upcoming needs, ensuring the platform evolves ahead of product requirements.  
  • Operational Excellence: Drive the reliability and observability of core platform services, establishing robust monitoring, alerting, and automated recovery processes.

What We're Looking For

  • 8+ years of engineering experience, with a strong background in platform or internal tools development
  • Deep experience with: 
    • Node.js + NestJS
    • PostgreSQL (including strong data modeling skills)
    • React (used in the context of platform UI libraries and applications)
  • Strong cross-functional collaborator: You live and breathe platform engineering, and you evangelize the power of a well-built platform.
  • Strong systems thinking: you've built frameworks, SDKs, design systems, or internal platforms that scale
  • A pragmatic, product-oriented mindset - you're focused on empowering other engineers through elegant abstractions
  • Demonstrated product sense: understands user needs (internal teams), avoids overengineering, and builds with a clear value proposition
  • Comfortable building and owning services in a service-oriented architecture
  • The strongest candidates have:
    • Experience in healthcare, workflow engines, permissions/RBAC systems, rules engines, or multi-tenant architectures
    • Experience maintaining a fleet of applications built on a common platform
    • Previous Product Management experience
    • Previous consulting or external customer facing experience

Nice to Have

  • Experience migrating mission-critical systems onto a new architecture
  • Familiarity with Domain Driven Design
  • Previous Python development experience

Why Join Us?

  • Work on important, meaningful problems in healthcare
  • Shape the foundation of a platform that will power dozens (eventually hundreds) of applications
  • Collaborate with a team that values design, pragmatism, and velocity
  • Competitive compensation, equity, and full benefits

Compensation Disclosure
The anticipated base salary range for this position is $170,000 - $190,000 in the Los Angeles market. Actual offers depend on skills, experience, and location, and may include additional components such as performance bonuses, stock options, and benefits.

Chorus Innovations is proud to be an equal-opportunity employer committed to building a diverse team. We welcome applicants of every background and provide reasonable 
accommodations throughout the hiring process. If you need assistance, email careers@joinchorus.com
