About Particle

Particle Health is revolutionizing healthcare data analytics and interoperability. Our mission is to unlock the power of medical records in an intelligent platform that focuses health back on the patient.

Through our modern data platform, we enable healthcare innovators—ranging from value-based care providers and payers to digital health companies and health systems—to access standardized, real-time patient data. By bridging fragmented data silos, Particle empowers organizations to tackle critical use cases such as care coordination, risk stratification, patient identity management, and regulatory compliance with ease and precision.

Our solutions of Snapshot, Signal, Navigator, and Workbench address the complex challenges of healthcare data analytics and interoperability, helping our customers transform data into actionable insights, improve patient outcomes, and streamline workflows.

About the Role

As a Senior API / Backend Engineer (Sr SWE II) at Particle Health, you'll play a key leadership role in building and maintaining the core services that power our healthcare data platform.

You’ll take ownership of major systems, contribute to architectural decisions, mentor other engineers, and help shape the evolution of our backend platform as we scale. You’ll collaborate closely with teams across engineering, product, and data to deliver high-quality solutions that serve the evolving needs of our healthcare partners.

  • Partner with product teams to translate requirements into technical solutions and support customer integrations.
  • What We Seek

    Required :

  • 7+ years of backend development experience focused on APIs and distributed systems.
  • Strong production experience in Golang; comfortable working in Python when needed.
  • Deep understanding of RESTful API design and scalable service patterns.
  • Experience with SQL / NoSQL databases and cloud environments (GCP, AWS, or Azure).
  • Hands-on experience with Docker, Kubernetes, and modern CI / CD tooling.
  • Demonstrated ability to design, build, and operate end-to-end systems independently.
  • Strong debugging, analytical, and communication skills.
  • Experience using AI-enhanced coding tools (Claude Code, Copilot, Cursor, etc.).
  • Bachelor's degree in CS / Engineering or equivalent experience.
  • Nice to Have :

  • Experience with healthcare data standards (FHIR, HL7, CCDA).
  • Familiarity with Data Engineering / ETL workflows or data engineering pipelines.
  • Experience with GCP
  • Experience with Infrastructure as Code, specifically Terraform
  • Event-driven architectures, message queues.
  • API security and authentication patterns (OAuth, JWT).

  • Knowledge of healthcare compliance frameworks (HIPAA, SOC2).
  • What You Bring :

  • A passion for building reliable, well-designed APIs.
  • Strong attention to detail and commitment to code quality.
  • Ability to balance technical excellence with delivery timelines.
  • Curiosity about healthcare tech and willingness to grow domain expertise.
  • Collaborative mindset and ability to support and guide teammates.
  • Initiative and ownership across complex technical areas.

  • Employer-funded 401(k) contribution to help you build a secure future.
  • Mental health benefits to support your well-being.
  • Invest in Your Future : Receive employee equity, ensuring you share in the company’s success.

  • At Particle Health, your contributions don’t just impact the company—they shape the future of healthcare. Join us, and let’s make a difference together!

    Compensation Range : For this role, we’re targeting a salary range of $190,000-220,000 annually, depending on experience and qualifications. If your background aligns more closely with a higher or lower level than the scope outlined here, compensation may vary accordingly.
