Job description

ModMed is hiring a driven Senior Software Engineer to join our Platform Foundations team. This is an exciting opportunity to join a fast-paced healthtech company that is truly Modernizing Medicine!

The Role

You'll be building for other engineers, not end users. Our \"customers\" are internal product teams. This reframes everything: API ergonomics, backward compatibility, and documentation aren't nice-to-haves—they're the core of the job.

Responsibilities:

• Own features/libraries end-to-end: design, implementation, documentation, and rollout.
• Design APIs with the consumers in mind, weighing backward compatibility and API ergonomics.
• Develop robust, scalable foundational services (e.g., enterprise-sharding, ema-hub) and maintain the internal Java/Spring Boot microservice framework (nicknamed Ragnarok).
• Debug across service boundaries and provide support to teams consuming the framework.
• Drive technical direction for foundational components and cross-cutting concerns, making architectural decisions with org-wide impact.
• Mentor engineers, raise the bar in code reviews, and lead developer-enablement efforts (patterns, docs, tooling).
• Build strong relationships across teams; explain complex tradeoffs to non-platform engineers.
• Maintain a support mindset, treating unblocking other engineers as a primary responsibility.

Skills and Requirements:

• Education: Bachelor's or Master's degree in Computer Science or a related field.
• Java: Strong proficiency with modern Java (records, sealed types, streams, concurrency); comfortable reading and reasoning about others' code.
• Spring Boot/Spring: Deep knowledge of auto-configuration, @Conditional beans, starters, and @ConfigurationProperties.
• Library/Framework Mindset: Experience designing clean public APIs, managing semantic versioning, deprecation paths, and mitigating breaking changes.
• Testing Rigor: Strong TDD approach using JUnit and Testcontainers; treats tests as first-class deliverables.
• Distributed Systems: Understanding of idempotency, at-least-once delivery, retries, backoff, distributed locking, and eventual consistency.
• Multi-tenancy: Knowledge of tenant/source-context propagation across HTTP/Kafka/SQS boundaries (relevant to enterprise-sharding).
• Data & Infrastructure:
• AWS (SDK v2): DynamoDB, S3, SQS, Athena, MySQL with IAM auth.
• Observability: Structured JSON logging, Micrometer/Prometheus metrics.
• Containers: Docker, docker-compose, Jib-based image builds.
• Soft Skills: Developer empathy, documentation discipline (cookbook-style), backward compatibility focus, and excellent communication.

Nice-to-Haves:

• OAuth2/scope-based authorization, security filter chains.
• Resilience patterns (Resilience4j).
• OpenSearch / Elasticsearch.
• Prior experience building internal platforms, SDKs, or developer tooling.
