Senior Java Backend Engineer

Praia Health

About The Position

Praia is seeking a Senior Software Engineer to take on a high-impact role with significant autonomy. In this role, you will establish deep, end-to-end architectural ownership of our platform, primarily driving high-performance Java backend services (80–90% of the focus) while supporting client-side integrations and platform needs in JavaScript (10–20%). This senior-level scope pairs you closely with engineering leadership to deliver resilient software at a steady, well-defined pace. You will ensure the delivery of secure, well-documented APIs used by internal teams and external health system partners. If you thrive on building scalable distributed services, collaborating on light front-end touchpoints, and tackling complex enterprise integrations, we want to hear from you.

Requirements

6+ years of experience building and operating production software, with demonstrated senior-level scope and clear ownership of distributed, high-throughput systems.
Expert-level software development skills in Java and the modern Java ecosystem (Quarkus or Spring Boot, concurrency, microservices).
Strong working knowledge of JavaScript/TypeScript and modern client-side architectures, comfortable owning light frontend integrations and UI-facing platform touchpoints.
Practical experience integrating with EMR/EHR systems and healthcare interoperability standards (FHIR, HL7, SMART on FHIR); equivalent background in heavily regulated sectors like FinTech is also valued.
Experience delivering cloud-native services (AWS, Azure, or GCP), container orchestration (Kubernetes/Docker), and Infrastructure as Code (Terraform).
Deep understanding of OAuth2, OIDC, mTLS, JWT, secrets management, and secure SDLC practices.
Hands-on experience with modern observability tooling (metrics, distributed tracing, APM, log aggregation) and operational triage.
Exceptional written and verbal communication skills; proven ability to write crisp technical design documents and articulate architecture trade-offs.
Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.
Must permanently reside in either the United States or Canada.
Must be currently authorized to work in the United States or Canada on a full-time basis.

Nice To Haves

Prior exposure to or hands-on experience with Databricks, Apache Spark, or distributed data processing is a plus, but not required.

Responsibilities

Architect, build, and scale core Java backend services powering Praia's consumer experience and platform ecosystem.
Collaborate on the frontend by developing and maintaining JavaScript components, UI workflows, and client-side integration hooks (10–20% of scope).
Build and operate enterprise integration services for EMRs (Epic/MyChart and others) utilizing HL7 FHIR APIs and modern interoperability patterns.
Leverage Databricks and Apache Spark to build or support data pipelines, workflows, and analytical workloads when integration needs arise.
Develop and maintain secure REST/event-driven APIs featuring robust authentication/authorization (OAuth2/OIDC), auditing, and least-privilege controls. Author clear developer documentation, OpenAPI specs, and runbooks.
Champion a modern DevOps mindset by owning CI/CD pipelines, automated testing (unit/integration/E2E), infrastructure-as-code, structured logging, and incident response.
Partner directly with Product, Design, and partner-facing teams to translate technical requirements into robust, frictionless solutions.
