As a Java Backend Developer, you need to develop and maintain the back end / server-side parts of an application, typically consisting of APIs, databases and other services containing business logic. They work with various languages and tools to create and maintain services on-prem or in the cloud.

Responsibilities Architect, develop, and operate highly performant and scalable asset management and access control services that handle massive data volumes and user demands. Utilize and contribute to a modern technology stack, designing, building, and deploying software solutions with technologies such as Kubernetes, Kafka, PostgreSQL, gRPC, and REST.

Leverage your strong technical acumen in cloud computing platforms and technologies to build resilient and efficient systems.

Contribute to the evolution and maintenance of a robust and intuitive data taxonomy, ensuring clarity and consistency across our platforms.

Demonstrate excellent coding skills and a passion for crafting high-quality, maintainable, and well-tested code that adheres to best practices.

Develop and maintain comprehensive monitoring and alerting systems to ensure the reliability, performance, and security of our services, minimizing customer impact during deployments and operational changes.

Experience Required A minimum of 8+ years of professional software development experience.

Java Strong experience in developing and maintaining microservices written in Java, ideally within a distributed, event-driven architecture. Our services handle vehicle command / control flows, provisioning, and metadata management, so solid understanding of concurrency, error handling, and performance tuning in Java is essential.

Spring Boot Developers are expected to design and implement Spring Boot-based REST or gRPC services, integrating with other platform components through APIs and Kafka topics. Experience with dependency injection, configuration management, and secure inter-service communication (e.g., OAuth2, mTLS) is key. Familiarity with Maven builds and CI / CD pipelines (Concourse, ArgoCD) is a plus.

Experience Preferred JavaScript Used primarily for internal dashboards / tools. Candidates should be able to understand and extend existing front-end or API middleware codebases when needed.

AWS / Kubernetes Strong knowledge of AWS services (EKS, RDS, MSK, IAM, ECR, etc.) and Kubernetes concepts (Helm, IRSA, networking, resilience) is preferred. Our workloads are containerized and run on AWS EKS, with infrastructure managed through Terraform. Candidates with experience troubleshooting production workloads in cloud-native environments will be highly valued.

Python Useful for automation and scripting tasks, such as CI / CD helpers, data processing scripts, or infrastructure tooling. Familiarity with boto3 (AWS SDK for Python) and API integration scripts is beneficial.

C# While not a core language for new development, some legacy services and calibration tools in the broader ecosystem are written in .NET. Ability to understand or support C# components for integration or migration purposes would be helpful.
