Senior Software Engineer, Particle Health

• This role is ideal for an experienced backend engineer who pairs strong technical judgment, architectural thinking, and systems-level ownership with curiosity about improving engineering practices and outcomes
• This role is best suited for engineers who have operated at a senior, staff, or technical lead level and are comfortable owning large, business-critical backend systems
• 8+ years of backend engineering experience, with sustained focus on APIs and distributed systems in production environments
• Strong production experience with Golang; comfortable working in Python when needed
• Significant experience using AI-assisted development tools (e.g., Copilot, Cursor, Claude Code) to implement features, improve engineering workflows, with sound judgment around quality, risk and maintainability
• Deep understanding of RESTful API design, scalable service patterns, and backend architecture
• Experience with SQL and/or NoSQL databases and cloud environments (ideally GCP)
• Demonstrated ability to design, build, evolve, and operate complex systems independently, including making architectural tradeoffs
• Strong debugging, analytical, and communication skills
• Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience

Desirable

• As a Senior Software Engineer II, Backend at Particle Health, you’ll play a key leadership role in building and scaling the core services that power our healthcare data platform and improve healthcare for millions of patients
• You’ll work primarily in Golang (with some Python) to design and operate robust, secure, and high-performance APIs that enable customers to reliably access and utilize healthcare data at scale
• Beyond owning complex backend systems, you’ll help shape how the engineering organization builds software, including advancing the team’s use of modern tooling — particularly AI-assisted development tools — to improve code quality, developer velocity, and system reliability
• You’ll collaborate closely with Product, Data, and Engineering teammates to deliver high-quality solutions in a highly regulated, mission-driven environment, operating with meaningful ownership and influence across the backend platform
• Design, develop, and maintain RESTful APIs and backend services using Golang (and some Python)
• Build scalable, secure, and performant services that handle healthcare data with strong privacy, security, compliance, and reliability requirements
• Leverage AI-assisted development tools to improve productivity, debugging, testing, documentation, and code quality; help define best practices and guardrails to ensure correctness, security, and maintainability
• Integrate backend services with data pipelines and processing workflows
• Take end-to-end ownership of complex systems, including architecture, implementation, observability, operational health, and long-term reliability
• Lead or meaningfully contribute to architectural discussions and long-term technical planning, balancing near-term delivery with long-term platform health
• Identify and implement measurable improvements to system performance, efficiency, scalability, and reliability
• Mentor engineers and contribute to improving engineering standards, tooling, and development practices
• Partner closely with Product to translate requirements into durable technical solutions, including supporting customer integrations and production use cases
