Java Full Stack Developer

Full‑Stack Development Engineer (FDE) — Java / Angular / GCPLocation: Remote (US) or Onsite in Brentwood, TN; candidates in CST or MST time zones strongly preferred.

Engagement: Full‑time with CitiusTech

Domain: US Healthcare

Role Overview

As an FDE, you’ll build end‑to‑end solutions—from backend microservices to modern UIs—deployed on Google Cloud Platform (GCP). You’ll embed with client stakeholders, translate business needs into technical designs, and deliver secure, scalable software. The work spans design, development, testing (QA), DevOps, and production deployments (E2E). Healthcare domain familiarity (clinical data, medications, orders, labs, revenue cycle) is a plus.

What You’ll Do (Responsibilities)

• Design, develop, test, and deploy Java microservices on GCP; implement resilient, observable services in a microservice architecture.
• Build responsive front‑end applications using Angular (component‑driven patterns, RxJS).
• Implement messaging/streaming integrations using Kafka and GCP Pub/Sub; design for at‑least‑once/exactly‑once semantics and back‑pressure.
• Work with GCP Kubernetes (GKE) for container orchestration; automate CI/CD and promote builds across environments.
• Model and optimize data access on Cloud Spanner; contribute to schema design, transaction strategies, and performance tuning.
• Own E2E quality: unit, integration, contract, and performance testing; drive high code coverage and automated quality gates.
• Collaborate across architecture, data modeling, security, and product teams; demo features, capture feedback, and iterate quickly.
• Document LLD/sequence diagrams, and contribute to coding standards, architecture guidelines, and re‑usable libraries.
• Support production (SRE/DevOps mindset): monitoring, alerts, incident response, and RCA.

Mandatory Skills (Must‑Have)

• 10+ years of professional software engineering experience; Java 8+ in production.
• 4+ years recent, hands‑on Spring ecosystem (Spring 4/5, Spring Boot 2+, Spring Data, Spring Cloud, Spring Integration, Spring REST).
• Angular/React (recent production experience).
• Event‑driven / asynchronous architecture; 4+ years integrating with brokers (Kafka / Pub/Sub) and applying appropriate design patterns.
• GCP hands‑on: GCS Buckets, Kubernetes (GKE), Pub/Sub, Kafka; infrastructure and services usage in production.
• Cloud Spanner experience (or strong NoSQL exposure with Cassandra/Couchbase and proven ability to ramp).
• Microservices design & implementation at enterprise scale.
• Strong testing discipline: JUnit5, Spring test (unit/integration), isolated layer testing, Hamcrest/AssertJ; mocking & debugging.
• Modern tooling: Git (enterprise workflows), Gradle/Maven, IntelliJ (preferred) or equivalent; CI/CD (Jenkins/GitHub Actions/Sonar).
• Agile delivery experience (Scrum/Kanban) with Jira; epic/story breakdown, estimation, demos, and acceptance.
• Clear communication, stakeholder engagement, and cross‑functional collaboration.

Good to Have

• Capacitor (Mobile iOS/Android) with Angular for cross‑platform apps.
• Windsurf AI (developer productivity/AI‑assisted workflows).
• Spring Boot 3, Reactive Spring (WebFlux), Hibernate/JPA.
• GCP Dataflow (batch/stream processing), CI/CD for mobile.
• React exposure, SCSS/SASS theming; reusable component libraries.
• Experience with Docker, SonarQube, Jenkins, GitHub/GitLab pipelines.
• Performance tuning (frontend and backend), cross‑platform optimization.
• US healthcare context—clinical data, medications, orders, labs.
• Open‑source contributions (plugins/libraries) and internal frameworks.

Nice to Have (Mobile / Capacitor Focus)

• Build and maintain Capacitor plugins to access native device features.
• Debug across web/mobile runtimes; familiarity with Xcode/Android Studio build steps.
• Exposure to hybrid / multi‑framework architectures and mobile testing.
• Gen AI / Agentic AI exposure to build workflows and agents using ADK, A2A and MCP

Education

• Bachelor’s/Master’s in Computer Science, Engineering, or related field.
• Relevant cloud or healthcare certifications are a plus.

How You Work (Mindset & Practices)

• Product‑thinking with a bias for measurable outcomes, reliability, and security.
• Ownership from design through production; E2E accountability for quality.
• Pragmatic documentation (LLD, ADRs) and clean code practices.
• Mentorship: guide junior engineers and contribute to technical direction.
• Curiosity about emerging frontend, mobile, and agentic AI technologies.

Work Hours & Location

• Operate primarily in CST/MST hours; onsite in Brentwood, TN when needed for collaboration is preferred. Remote is supported for qualified candidates.
