System Validation Engineer

Join our project team dedicated to secure identity and document solutions. We are looking for a hands-on System Validation Engineer with strong Linux and deployment knowledge and practical experience validating complex system environments. The primary focus of this role is hands-on validation and integration testing of complete system landscapes — including infrastructure, deployments, APIs, integrations, and environment configurations.

Strong practical experience in system validation, integration testing, or technical end-to-end testing Strong Linux knowledge, including command line usage, administration, and shell scripting Hands-on experience with AWS and Linux-based infrastructure Experience with Docker and CI/CD pipelines Strong troubleshooting and root cause analysis skills Strong scripting skills (Python and/or Bash) Understanding of networking, infrastructure, deployment processes, and environment configuration Experience working with REST APIs, JSON, YAML, XML, and API testing tools Solid SQL knowledge (e.g. PostgreSQL) Ability to understand and validate complex distributed systems Experience with automated testing and validation tools Experience with Kubernetes environments Ability to read and understand Java code (development not required) Experience with Windows environments and administration Experience with secure identity, PKI, authentication, or document management solutions Experience with infrastructure automation and configuration management

Strong engineering mindset with ownership for system stability and quality Passion for testing and validating complex technical systems in real-world environments Comfortable working independently across validation, deployment, infrastructure, and troubleshooting tasks Detail-oriented with strong analytical and problem-solving skills Collaborative and clear communicator
