We are looking for a Senior Backend Developer for an important U.S.-based client.
Project: Acceleration of platform alignment and deployment repeatability to support large, complex customer engagements and regulated environments, with an emphasis on improving release velocity, architectural consistency, and time-to-market.
What you’ll do

Build and enhance Java microservices running on Kubernetes (EKS strongly preferred)
Implement APIs and service workflows with production-grade quality (tests, telemetry, docs)
Help scale services (autoscaling, performance tuning, resilience patterns, safe rollouts)
Integrate with AWS services (commonly DynamoDB, S3, ELB/ALB/NLB, Route 53, KMS)
Improve reliability and operability: logging, metrics, tracing, dashboards, alerts, runbooks
Participate in code reviews and collaborate with staff engineers on designs and implementation details

Must-haves

6 to 8+ years' experience
Quarkus or Helidon experience (strong preference)




Strong Kubernetes experience (deployments, debugging, resource tuning); EKS experience is a big plus
Hands-on experience with microservices patterns: retries/timeouts, idempotency, async workflows, backward-compatible APIs
Strong communication and ability to deliver independently with minimal ramp time

Nice to have (strongly preferred)

Observability tooling (OpenTelemetry, Prometheus/Grafana, Coralogix, ELK, etc.)
Experience with CI/CD pipelines and release strategies (blue/green, canary, feature flags)

What success looks like (examples)

Ship production changes within the first 1–2 weeks (after access + brief onboarding)
Deliver services/features with tests + instrumentation + deployment artifacts
Reduce incidents/toil and improve SLO posture via operational improvements
