Java backend and full-stack engineers. Turning a visit into a claim, checking it against the insurer's rules and tracking the payment is transaction processing on sensitive data. Java engineers build these services at Inovalon, HealthEdge and the claims network Availity, in Spring Boot with React or Angular on AWS and PostgreSQL. They are the most common opening here, in about their usual proportion.

Software Engineer, Healthtech. Many companies here hire under a plain software engineer title. Most of these roles are ordinary product work at HealthEdge, Inovalon and the prior-authorisation company Cohere Health, in JavaScript, React and Python on AWS or Azure, where healthcare is the setting rather than the skill, though many postings still require knowledge of HIPAA, the American law on protecting patient data. A smaller part is defined by healthcare itself and requires HL7 and FHIR, the formats in which health records and claims data are exchanged, mostly at the health-data platform Innovaccer and Availity. Together, healthtech software engineers are several times as common here as at a typical product company.

.NET engineers. The core systems of health insurers and of state health programmes were largely built on the Microsoft stack. .NET engineers build and modernise them, in C# with ASP.NET, Entity Framework and SQL Server, under React or Angular. They are well above their usual weight here, concentrated in The insurer's side, and they are hired almost entirely with experience.

Test engineers. A claim paid wrongly costs real money and breaks rules. Testers are above their usual weight, mostly at Inovalon, and an unusual share of the postings are for manual testing alongside automation in Cypress, Playwright and Selenium, with JMeter for load.

Backend engineers not tied to one language. Inovalon hires almost all of a large group of backend engineers whose postings name security, especially Spring Security, rather than a single language. This group is several times as common here as elsewhere.

Data engineers. Claims and payments produce large data sets for analytics and audits. Data engineers build those pipelines in Python and Java with Spark and Snowflake, mostly at Inovalon.

Frontend engineers. Insurer and provider staff work in claims and authorisation screens all day. Frontend engineers build them in React with TypeScript and Redux, mostly at HealthEdge.

Python backend engineers. Innovaccer builds much of its product in Python, with Django, FastAPI and Kafka, and it hires most of the Python engineers here.

Also present. Full-stack engineers at Inovalon, entry-level application roles and a few Software Engineer, Security roles on identity there, a small group of GenAI engineers at the AI billing agents, like CombineHealth and Arrow, and Innovaccer, and a few cloud engineers, far below their usual weight.

Rare here. SAP, firmware and C/C++ work barely appear.
