Job description

Overview
  • Tier One Technologies is seeking a Microservices Developer to support our US Government client.
  • This will be a 100% remote contract-to-hire position.
  • SELECTED CANDIDATES WITHOUT REQUIRED CLEARANCE WILL BE SUBJECT TO A FEDERAL GOVERNMENT BACKGROUND INVESTIGATION TO RECEIVE IT.

Responsibilities
  • Design, build, and maintain Spring Boot microservices using Java 21 and Java 25.
  • Create and evolve RESTful APIs with clear contracts, versioning, and backward compatibility.
  • Implement input validation, error handling, idempotency, and standardized response models.
  • Integrate services with on-prem and AWS-hosted databases during migration phases.
  • Plan and execute data-access changes to support hybrid connectivity (on-prem to AWS) safely.
  • Optimize database interactions, including query tuning, connection pooling, and transaction boundaries.
  • Containerize services and maintain production-ready Docker images.
  • Deploy and operate services on Kubernetes with health probes, resource limits, and autoscaling.
  • Build and maintain CI/CD pipelines for build, test, security scan, and deployment automation.
  • Implement secure service-to-service and client authentication/authorization.
  • Manage secrets and configuration using AWS-native and Kubernetes-native approaches.
  • Add observability: structured logging, metrics, distributed tracing, dashboards, and alerting.
  • Troubleshoot incidents across application, container, cluster, network, and database layers.
  • Improve resiliency with retries, timeouts, circuit breakers, and graceful degradation patterns.
  • Participate in migration planning from on-prem infrastructure and data stores to AWS.
  • Support release validation in staging and production, including rollback readiness.
  • Write and maintain unit, integration, contract, and performance tests.
  • Address vulnerabilities by upgrading dependencies and remediating CVEs in application libraries.
  • Collaborate with QA, platform, security, and architecture teams on standards and best practices.
  • Document APIs, operational runbooks, and service ownership responsibilities.

Qualifications
  • A degree from an accredited College/University in the applicable field of services is required. If the individual's degree is not in the applicable field, then 4 additional years of related experience is required.
  • 8+ years of experience in IT software development.
  • Strong knowledge of Spring Boot microservices.
  • Hands-on experience with Java 21 and Java 25.
  • Excellent communication skills.
  • Must be a US Citizen or have Permanent Residence status (Green Card).
  • Must be able to obtain a Position of Public Trust Clearance.
  • Must be able to pass a drug screening, criminal history, and credit checks.
  • Must have lived in the United States for the past 5 years.
