Senior Platform Lead — Java/Kotlin

About Plexis

Plexis lets healthcare teams visually build and deploy governed workflows across EHR, ERP, scheduling, lab, messaging, and internal systems.

What you’ll build

You’ll own the workflow definition engine and agent runtime that executes workflows across systems.

Responsibilities

• Design and implement the core backend services (Kotlin/Java, Spring Boot).

• Build durable workflow execution (timers, retries, idempotency, compensation) using a workflow engine (Temporal preferred).

• Implement governance primitives: RBAC, policy checks, approval gates, audit logging, versioning/rollback.

• Define the platform’s internal APIs (REST external, gRPC internal) and service boundaries.

• Own reliability: observability, on-call hygiene, incident response patterns, performance and scaling.

• Partner with integration/data engineers to consume normalized episode/event streams safely and consistently.

Requirements

• 8–12+ years backend/platform engineering experience.

• Deep production experience in Kotlin/Java + Spring Boot (or equivalent JVM stack).

• Strong distributed systems fundamentals (consistency, idempotency, retries, async patterns).

• Experience designing secure enterprise software (authn/authz, secrets management, audit logs).

• Comfortable working in a small team: you can ship and you can design.

Nice to have

• Temporal/Cadence/Conductor/Airflow-like orchestration experience.

• Healthcare integration familiarity (HL7/FHIR) — not required.

• Experience building multi-tenant SaaS.
