Senior Software Engineer, Billing Workflow

Join us as we work to create a thriving ecosystem that delivers accessible, high-quality, and sustainable healthcare for all.

Role summary:

This Senior Software Engineer will design and build scalable, secure, and maintainable software that powers athenaCollector’s revenue cycle management features. This role is based in Boston, MA as a hybrid position. The engineer will collaborate across product, design, and operations teams to deliver high-quality services and will report to the Senior Manager.

Team summary:

In athenaCollector we build technology solutions that automate Revenue Cycle Management (RCM). This Collector team is implementing the underlying medical back-office processes to automate and integrate the unique claims cycle requirements.

The athenaCollector product builds a critical part of the athenaOne platform, which helps our medical provider clients manage their business and revenue cycle (RCM), automating claims and billing for well over $200 billion in client revenue. This team focuses on providing both clients and athena teams with the right features and tools to minimize cash flow delays and operational costs, increase scalability, and help clients maximize the value they get from athenaOne.

On this team you will work on services and user experiences that directly impact claims processing, billing, and client operations. You will help reduce manual work through automation, improve system observability and reliability, and deliver features that drive measurable business outcomes for provider clients. Collaboration with product managers, QA, SRE, and other engineering teams is central — you’ll participate in design discussions, code reviews, and delivery planning while mentoring more junior engineers and contributing to technical roadmaps.

Essential Job Responsibilities:

• Design and implement frontend user interfaces using React, JavaScript, HTML, and CSS that deliver performant and accessible experiences.

• Develop and maintain backend services using Java and Spring Boot to support core RCM workflows and APIs.

• Build and consume GraphQL APIs to efficiently fetch and manipulate data across services.

• Create, optimize, and maintain SQL-based data models and queries for Oracle and PostgreSQL databases.

• Deploy and run containerized services on AWS (ECS, EKS) and collaborate with platform/SRE teams to improve reliability and observability.

• Implement infrastructure-as-code patterns and collaborate on DevOps automation, familiarity with Terraform is a plus.

• Apply Agile methodologies: participate in sprint planning, refine requirements, estimate work, and deliver high-quality increments.

• Integrate and evaluate AI capabilities into engineering workflows and product features, prototype LLM-assisted features, and help define safe, usable ways to leverage AI to improve developer productivity and client outcomes.

• Collaborate in cross-functional teams: perform design reviews, code reviews, and mentor peers to raise overall engineering quality.

• Troubleshoot production issues, perform root-cause analysis, and implement long-term fixes that reduce operational risk.

Additional Job Responsibilities:

• Contribute to architectural discussions and help drive technical strategy for the product area.

• Participate in on-call rotation and support incident response processes when needed.

• Produce technical documentation, runbooks, and API documentation for internal and external stakeholders.

• Support performance tuning and scalability testing of services and queries.

• Prototype new ideas and present findings to product and engineering leadership.

• Help onboard new hires and support team learning sessions.

Expected Education & Experience:

• Bachelor’s degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.

• 4–8 years of professional software development experience.

• Strong experience building frontend applications using React, JavaScript, HTML, and CSS.
