Senior Software Engineer

Quick Facts

• Role: Senior Software Engineer (Cost Engine team)
• Focus: Core backend services and REST APIs for healthcare cost, rate, eligibility, benefits, and related data
• Work style: Hands-on engineering with mentoring and technical leadership; Agile delivery; on-call incident response

Description

You will design, build, and run the core API and backend service that standardizes and serves healthcare procedure cost and related data for downstream products. This is a hands-on senior role where you write and review production code, raise engineering standards, and help turn the roadmap into shipped, reliable software.

Responsibilities

• Mentor and influence technical direction in partnership with the Principal Engineer and architecture; lead by example via thoughtful design and code reviews
• Write and review production code across .NET REST APIs, C# services, Rust microservices, and ETL/data-movement pipelines
• Set and uphold engineering standards for code quality, testing, and observability
• Own complex/high-risk work, including design decisions and thorny production issues
• Deliver end-to-end features: API contracts, data models, deployment, and monitoring
• Tune performance of high-throughput APIs and SQL queries serving cost and rate data
• Participate in on-call rotation, lead incident response, and drive root-cause fixes
• Support Agile planning and delivery predictability; break work into scoped tasks, estimate effort, and flag risks early
• Balance new feature delivery with platform health (security, reliability, and maintenance)
• Communicate progress, delivery risk, tradeoffs, and decisions early with Product and Principal Engineering

Requirements

• 5+ years of software engineering experience with strong hands-on coding (BS + 5 years or MS + 3 years)
• Experience mentoring engineers and leading technical design and code reviews
• Depth in C#/.NET for production REST APIs and backend services
• Experience with relational databases (SQL Server and/or PostgreSQL)
• Experience with cloud-hosted services on AWS
• Comfort operating in Agile environments (sprints, PI planning, commitment-based delivery)
• Ability to work across hybrid legacy and modern codebases with security and reliability in mind
• Strong fundamentals in software design, automated testing, and CI/CD
• Low-ego, collaborative mindset

Preferred

• Healthcare IT experience (member cost, claims, benefits, or price transparency; X12 EDI 270/271 and 837; No Surprises Act; Transparency in Coverage)
• Experience modernizing legacy systems and service decomposition/migrations
• Familiarity with Rust, distributed caching (Redis/Valkey), messaging (SQS/RabbitMQ), and observability (Datadog, OpenTelemetry)
• Experience with containers and infrastructure as code (Docker, ECS/Kubernetes, Terraform)
• Knowledge of healthcare data privacy and security (PHI/PII)
• Experience with Jira and Confluence
