Our principles

We learn fast, design for scale, build pragmatically, and treat quality as a team sport. The impact you’ll have You’ll design, build, and operate scalable, secure microservices that power mission‑critical logistics flows. Your work will modernize our backend architecture (APIs, streaming, data access), improve reliability and performance, and raise engineering standards across teams. What you’ll do Design & Development Build robust backend services in Java (21+) with Spring Boot 3 (REST APIs, data access, messaging).

Implement event‑driven streaming with Kafka (KStreams/KConnect), and request/response services. Design, implement, and maintain public APIs (REST/OpenAPI), and integrate vendor APIs with rate limiting & caching. Model and optimize data in MongoDB / PostgreSQL (schema design, indexing, query performance). Refactor legacy monolith components into microservices with clear boundaries and resilient communication. Quality, Observability & Security Write unit/integration/contract tests (JUnit/Mockito/Testcontainers; load tests with Gatling where needed) and embed them in CI/CD.

Ensure logging, metrics, tracing and alerts are implemented (ELK/Prometheus/Grafana/OpenTelemetry) and integrated with central platforms. Follow secure coding practices; implement OIDC/OAuth2/RBAC, data privacy, and audit logging. Delivery & Operations Build, test, and deploy via Jenkins/Argo/Azure DevOps pipelines, containerized with Docker, orchestrated on Kubernetes.
