Role Overview:
As a Senior Cloud Native Software Engineer at TenneT, your key responsibilities will include:
Designing, developing, and maintaining robust Java/Python applications, focusing on performance, reliability, security, observability, and scalability.
Containerizing and deploying workloads to Kubernetes clusters using best practices for CI/CD, monitoring, and fault tolerance.
Implementing comprehensive test coverage, including unit, integration, and system tests to ensure code quality and stability.
Diagnosing and resolving issues uncovered during testing or reported in production, with an emphasis on root cause analysis and sustainable fixes.
Continuously improving codebases, deployment pipelines, and team practices through proactive suggestions and hands-on implementation.
Actively collaborating in design discussions, code reviews, and knowledge-sharing sessions to foster a strong engineering culture.
Participating in periodic standby/on-call rotations, approximately once every two months, to support mission-critical services during off-hours.

Experience in developing and operating production-grade backend applications, preferably in Java or Python. A solid understanding of cloud-native design principles, distributed systems, and microservice architectures. Proven experience in deploying containerized applications on Kubernetes in production environments.
Comfort working with streaming platforms like Apache Kafka, and ideally familiarity with one or more stream processing frameworks such as Apache Flink, Kafka Streams, or Apache Beam.
Experience with infrastructure-as-code, CI/CD pipelines (e.g., ArgoCD, Terraform, Tekton, GitHub Actions), and modern DevOps practices (e.g., GitOps, observability, auto-scaling).
Familiarity with cloud object storage (e.g., MinIO, S3) and modern databases (e.g., MongoDB, PostgreSQL/TimescaleDB).
Bonus points for experience in data-intensive applications, including time-series data, analytics, or real-time processing.
Comfort working in an agile, cross-functional team and taking ownership across the software delivery lifecycle.

Willingness to participate in a night-time standby/on-call rotation (approximately once every two months) to support business-critical systems.
A bachelor’s or master’s degree in a technical field (e.g., engineering, mathematics, physics, computer science).
