Software Developer (Microservices) (Remote)

Overview

The Microservices Developer will be responsible for designing, building, and maintaining scalable backend services that power the platform's RESTful APIs. The role involves developing production‑grade microservices using Java 21 and Java 25, implementing clean and consistent API contracts, and ensuring secure, reliable integration with internal and external systems. The developer collaborates closely with product, architecture, and QA teams to deliver high‑quality releases, support deployment and validation in staging and production, and troubleshoot issues across distributed environments. Over time, the developer will drive improvements in service performance, resiliency, and observability while contributing to shared engineering standards, reusable components, and automation across the microservices ecosystem. Strong problem‑solving skills, clear communication, and a commitment to continuous improvement are essential for success in this role.

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.

Required Skills and Experience

• Minimum of eight (8) years of relevant experience.
• A degree from an accredited college or university in the applicable field. If the degree is not in the applicable field, four additional years of related experience are required.
• Typically performs all functional duties independently.
• Special credentials (licenses and/or certifications) may be required on a task‑order basis.
