Software Engineer - System Operations- DevOps

Responsibilities / Tasks

We are seeking a skilled Software Engineer with a strong DevOps focus to join our SystemOperations team. While contributing to core application development, you will take ownership of release automation, CI/CD pipeline evolution, and the automation of development, testing, and integration workflows. You will support and enhance our engineering ecosystem—including GitHub, Atlassian tooling, Nexus, and SonarQube—ensuring secure, efficient, and scalable delivery processes. This role combines hands-on development (NestJS, Angular, GraphQL, SQL, MQTT, event-driven systems) with responsibility for DevOps practices and environment administration.

• Design, build, and optimize CI/CD pipelines for backend and frontend applications.

• Drive release automation, including versioning, packaging, artifact management, deployment workflows, and environment promotion strategies.

• Automate recurring development and testing processes (static analysis, integration tests, end-to-end tests, environment provisioning).

• Administer and maintain core development infrastructure and tooling:

  • GitHub and GitHub Actions

  • Atlassian ecosystem (Jira, Confluence, Bitbucket where applicable)

  • Artifact repositories (e.g., Nexus)

  • Code quality and security scanning tools (e.g., SonarQube)

• Improve developer experience through workflow optimization and tooling enhancements.

• Monitor and enhance pipeline reliability, performance, and observability.

• Design, develop, and maintain features within the SystemOperations application suite.

• Build backend services using NestJS.

• Develop and maintain Angular-based frontend applications.

• Implement and manage GraphQL APIs, SQL databases, and event-driven communication workflows (e.g., MQTT, message brokers).

• Integrate new devices and services into the platform.

• Work with lower-level network protocols such as DHCP and mDNS.

• Use Docker for containerization and local environment standardization.

• Ensure development aligns with IEC-62443-3-3 and IEC-62443-4-1 security standards.

• Collaborate cross-functionally to design and deliver robust solutions.

• Troubleshoot performance, deployment, and environment stability issues.

Your Profile / Qualifications

Essential

• Proven experience as a Software Engineer with exposure to DevOps workflows and tooling.

• Strong knowledge of Docker and automated deployment practices.

• Experience with GraphQL, SQL, MQTT, and event-driven architectures.

• Practical experience with NestJS and Angular.

• Familiarity with IEC-62443-3-3 and IEC-62443-4-1 standards, or willingness to learn.

• Strong problem-solving and debugging skills.

• Excellent communication skills and collaborative mindset.

Nice to Have

• Experience administering GitHub, Nexus, SonarQube, or Atlassian systems.

• Experience with automated testing frameworks (unit, integration, E2E).

• Understanding of networking protocols such as DHCP, mDNS, and local service discovery.

• Exposure to Machine Learning, Generative AI, RAG, or related frameworks.
