We're Looking for a Sr Java Platform Development Engineer Position type: Contract to Hire Duration: Estimated 3-6 Months We are looking for a Senior Software Engineer to join the Platform Development team building and evolving the On-Demand Environments platform - an internal self-service deployment orchestration system used by hundreds of application teams. You will own backend services, command-line tooling, and AI-powered Claude Skills that automate the full deployment lifecycle across Amazon Elastic Container Service (ECS), Kubernetes, and serverless targets. Job Responsibilities Design & Deliver ODE Platform Features: Own end-to-end delivery of ODE command-line tooling, backend services (Java / Spring Boot), and deployment orchestration integrations. Design for correctness, observability, and resilience across distributed cloud deployments. Secure, Production-Quality Code: Write secure, high-quality production code adhering to application security standards (injection prevention, authentication, authorization). Implement deployment prerequisite checks, credential vault integrations, and access management workflows. Architecture & Design Artifacts: Produce and maintain high-level design documents, architecture decision records (ADRs), and deployment architecture diagrams. Ensure design constraints around scalability, availability, and zero-downtime deployments are reflected in code and validated through automated checks. Data & Observability: Build and maintain application performance monitoring (APM) dashboards and structured logging pipelines. Proactively identify deployment failure patterns from telemetry and translate insights into platform improvements. Developer Experience & Community: Contribute to engineering communities of practice around ODE best practices, Claude Skills development, and deployment automation. Share lessons learned from real-world delivery back into shared knowledge bases and team documentation. Inclusive Team Culture: Champion diversity, inclusion, and psychological safety within the team. Actively mentor junior engineers and participate in cross-team platform initiatives. Required Qualifications, Capabilities & Skills Hands-on Java development with Spring Boot, Spring MVC, Spring Data, Spring Security; experience building RESTful microservices deployed to containerised environments.
