Responsibilities: Deliver features end-to-end across the Synapse stack: React/Vite frontend, Node.js/Express/Apollo GraphQL backend, MongoDB/Elasticsearch data layer, and the surrounding Kubernetes deployment. Operate AI coding tools (Claude Code, agentic workflows, LLM-assisted code review) as a first-class part of the workflow — write effective prompts, critically evaluate AI-generated diffs, and know when to override the model. Contribute to HL7 v2 / FHIR / immunization data pipelines, including Kafka-based ingestion and Elasticsearch indexing. Instrument new work with structured logging (Pino), OpenTelemetry tracing, and Prometheus metrics; debug across the Grafana / Tempo / Loki / Pyroscope stack. Handle PHI safely — apply secure coding practices, use PII-safe span attributes, and flag security concerns during code review. Participate in code review, both giving and receiving; provide constructive feedback on correctness, security, and observability. Work independently on defined features and escalate blockers early; drive small-to-medium initiatives from concept to completion. Troubleshoot across the deployment path: application code, MongoDB/Elasticsearch, Kafka consumer, and the Kubernetes / Helm / ArgoCD / Kargo pipeline. The mission of Harris Global Business Services (GBS) is to exclusively serve Harris BUs across all verticals as a turn-key Center of Excellence for global offshoring in different countries around the world. GBS offers services to support Harris BUs in recruiting, hiring, onboarding, training, and retaining highly qualified employees based on BU requirements. We are currently building new or expanding existing offshore teams in Costa Rica, India, Bolivia and the Philippines. GBS creates a customized recruitment campaign to hire Harris FTEs across the full spectrum of services, including R&D, Customer Support, Professional Services and Sales roles, along with corporate services including Finance, CIT, M&A, HR, Payroll, Compliance and Legal. We are committed to supporting our diverse, highly skilled, multi-national workforce with an outstanding corporate culture and strong engagement initiatives for all employees. As part of our recruitment process, we use artificial intelligence (AI) tools during the initial screening phase to help identify candidates whose qualifications most closely align with the requirements of the role. This technology supports efficiency and consistency in the early stages, but it never replaces human judgement. All subsequent evaluations and final hiring decisions are made by our recruitment professionals. AI does not make final hiring decisions.
