Job description

Join our engineering team and help build the backend platform that powers Jacobian's AI-driven radiology reporting solution. In this role, you'll design and develop the cloud-native backend services and APIs that product teams build on - establishing the patterns, boundaries, and foundations that make our platform secure, observable, and scalable.

You'll work across backend engineering, data architecture, security, and cloud runtime - contributing to both greenfield platform work and the ongoing transition from legacy systems to cloud-native infrastructure.

This is a hybrid role based out of our Pittsburgh, PA office, with an expectation of 2–3 days onsite per week.

What you'll do

• Design and build foundational backend services and APIs using Java and Spring Boot, enabling secure and configurable product workloads in the cloud
• Define clean API contracts, versioning strategies, and service boundaries to reduce coupling across systems
• Design schemas and data access patterns using PostgreSQL, and apply object storage (S3 / MinIO) for large payloads, exports, and artifacts
• Implement authentication and authorization using OAuth2 / OIDC, and define RBAC and entitlement models at the service level
• Integrate with enterprise identity providers and ensure secure service-to-service credential handling
• Build services intended to run on Kubernetes, including readiness/liveness probes, scaling behavior, and resource profiles; collaborate on deployment manifests and Helm charts
• Lead Architecture Decision Records (ADRs) for platform and cross-team decisions, and review designs with a long-term systems perspective
• Partner with frontend, reliability, CI/CD, and security engineers to help product teams adopt platform patterns safely and consistently
• Evaluate and apply NoSQL systems where appropriate for high-scale reads, events, or specialized workloads

What you bring

• Strong backend engineering experience in Java with hands-on Spring / Spring Boot
• Solid fundamentals with relational databases, preferably PostgreSQL
• Experience with object storage systems such as S3 or MinIO
• Solid understanding of OAuth2 / OpenID Connect and service-to-service authentication
• Experience designing or operating multi-tenant SaaS systems
• Experience deploying and operating services on Kubernetes
• A track record of supporting and improving production systems

Nice to have

• Experience with NoSQL databases such as Cassandra or MongoDB
• Experience with configuration or control-plane systems
• Familiarity with observability tooling across metrics, logs, and tracing
• Prior exposure to architectural governance or ADRs

• Join a fast-growing healthcare technology company shaping the future of AI in radiology
• Work on meaningful products that improve radiology workflows and support better patient outcomes worldwide
• Be part of a mission-driven team that values trust, quality, collaboration, and innovation
• Enjoy flexible working hours and a hybrid work arrangement
• Competitive compensation and benefits package, including comprehensive health insurance, and a 401(k) with employer contributions
