About this role
We are looking for a Java Software Developer to join our team in Indaiatuba. You will work in a global, agile environment to design, build and operate cloud‑native, AI‑enabled backend services that power Ericsson BOS products. This is a hands‑on development role focused on Java (with additional Python), where you will design and implement features, APIs and microservices on Kubernetes‑based platforms, collaborating closely with other developers, architects and SREs across sites.
What you will do
-
Design, develop and maintain Java‑based backend services for BOS products, from requirements and architecture through deployment and operations.
-
Implement RESTful APIs, microservices and integrations using Java, and where relevant Python.
-
Write clean, testable, well‑documented code (including unit and integration tests), following engineering best practices and code review standards.
-
Build and operate services on Kubernetes‑based platforms on AWS and Azure, ensuring scalability, reliability, security and cost‑efficiency.
-
Contribute to and consume CI/CD pipelines and GitOps workflows to enable frequent, safe deployments.
-
Use and continuously improve observability for your services with tools such as Prometheus, Grafana, OpenTelemetry, Jaeger/Zipkin and ELK/EFK.
-
Apply secure‑by‑design principles in code and configurations, working with platform teams on IAM, TLS, secrets management (Vault/KMS) and service meshes (Istio/Linkerd).
-
Participate in technical design discussions, code reviews and architecture decisions, collaborating closely with platform engineers and SREs to onboard and evolve services on the platform.
The skills and knowledge you will bring
-
Proven experience as a Java Software Engineer / Backend Developer working on cloud‑native systems.
-
Strong coding skills in Java (Java 8+; ideally Java 11 or later) and solid experience with Python for backend and tooling.
-
Fluent technical english
-
Experience with Java frameworks such as Spring / Spring Boot (or similar) for building microservices and REST APIs.
-
Strong hands‑on experience with Kubernetes architecture and core objects (Deployments, Services, etc.), including operators/CRDs.
-
Practical experience with containerization and runtime tooling: Docker, Containerd.
-
Hands‑on experience with Helm/Helmfile for packaging and deploying services on Kubernetes.
-
Practical experience with AWS and/or Azure and core cloud services (containers, networking, storage, managed databases).

Background in CI/CD using tools such as Jenkins, GitLab CI and/or Spinnaker, plus exposure to GitOps practices.
-
Solid communication skills in English, comfortable working in a distributed, global engineering community.
-
Experience working in Agile teams, with strong collaboration skills and the ability to take ownership of features and support production services.
Good to have
-
Experience with observability tools such as Prometheus, Grafana, OpenTelemetry, Jaeger/Zipkin and ELK/EFK.
-
Good understanding of cloud security fundamentals: IAM, TLS certificate handling, secrets management (Vault, KMS) and service meshes (Istio/Linkerd).
-
Demonstrated interest or experience in applying AI/ML techniques to software engineering challenges.
-
Familiarity with automated testing practices and frameworks.
-
Experience mentoring more junior engineers and contributing to technical roadmaps and standards for Java services.
