Role Overview

We are looking for a Senior DevSecOps contractor to support the modernization of our application deployment and delivery landscape. This is a highly hands-on role: the selected contractors must have extensive practical experience and be able to contribute from day 1 with minimal ramp-up.

The main focus will be migrating an existing application from Docker Compose to Kubernetes workloads running on k3s.

This is a delivery-focused role. We are looking for engineers who can assess the current setup quickly, propose pragmatic improvements, and implement them directly.

Important: we will only consider candidates whose primary professional experience is as a DevSecOps Engineer. Profiles coming mainly from software development, infrastructure, system administration, or security roles with only partial DevSecOps exposure will not be considered.

Key Responsibilities

• Migrating containerized applications from Docker Compose to Kubernetes (k3s)
• Designing, building, and maintaining secure CI/CD pipelines in Azure DevOps, GitLab CI/CD, or Jenkins
• Integrating security controls into the delivery process, including static code analysis, dependency scanning, container image scanning, secrets detection, image signing, vulnerability management, and release gates
• Supporting deployment automation, environment promotion, rollback, traceability, and release reliability
• Working closely with development, infrastructure, and security teams to improve automation, resilience, and secure delivery practices
• Troubleshooting and resolving build, deployment, and runtime issues across CI/CD and Kubernetes environments
• Documenting implemented solutions and contributing to good DevSecOps practices across the team .
  
  

Required Experience And Skills

• 6 years of professional experience in DevSecOps , Platform Engineering, or closely related roles, with DevSecOps as the main professional focus.
• Strong hands-on experience with Docker and Kubernetes; experience with k3s is highly desirable.
• Proven experience transitioning workloads from Docker Compose to Kubernetes.
• Strong practical experience implementing CI/CD pipelines in Azure DevOps, plus GitLab CI/CD or Jenkins.
• Strong hands-on experience with DevSecOps and software supply chain security practices, including SAST, dependency scanning, container/image scanning, secrets handling, and image signing.
• Good understanding of cloud or hybrid infrastructure, Linux environments, and automation/scripting.
• Experience with Git-based workflows, Agile/Scrum delivery, and collaboration tools such as Azure DevOps, GitLab, and Jira.
• Strong troubleshooting, communication, and documentation skills.
• Good spoken and written English.
