Job details
Description: Client is seeking a highly motivated Senior Software Engineer (Golang) on a contract basis to contribute to strategic initiatives in supply chain security and cloud-native security. This role requires technical expertise in the implementation and continuous improvement of security controls across infrastructure supply chain, containerized environments, and security automation (including AI/ML/LLM solutions). You will be a key contributor in implementing security best practices for our containerized environments and maturing our overall security posture. Provide technical support and engineering solutions for securing Kubernetes (K8s) and containerized workloads, including runtime security, network policies, and admission controllers. Our Ideal Candidate Will Have: Strong practical experience in building and operating security automation specifically in Golang (Go). Deep, proven experience with container security, including designing, deploying hardened container images, and securing Kubernetes clusters. Advanced knowledge of Application security (OWASP Top 10). Experience with Infrastructure as Code (IaC) tools, especially Terraform, for provisioning security controls. Expertise in using GitHub, and CI/CD systems (GitHub Actions, Jenkins) from an architectural and engineering perspective. Expert-level proficiency in Software Composition Analysis (SCA) and hands-on experience in the practical remediation of third-party and open-source dependency vulnerabilities at scale. Direct experience or strong conceptual understanding of applying AI/ML, Large Language Models (LLMs), or MCP techniques to security challenges (e.g., automated vulnerability fixing, intelligent alert grouping). Expert familiarity with cloud platforms (AWS, Azure) and their security services, with a focus on container orchestration. Experience with supply chain security frameworks (e.g., SLSA).
What you’ll do
Build and improve security automation and controls for infrastructure supply chains, containerized environments, and cloud-native systems. Engineer security solutions for Kubernetes and container workloads, including runtime security, network policies, admission controllers, and security automation.
Requirements
Requires strong practical experience building and operating security automation in Golang, deep container and Kubernetes security expertise, and advanced application security knowledge. Candidates should also have experience with Terraform, GitHub and CI/CD systems, large-scale dependency vulnerability remediation, cloud security on AWS or Azure, and supply chain security frameworks; familiarity with AI/ML, LLM, or MCP security applications is expected.
