Platform Security Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Platform Security Engineer based in Switzerland. We are looking for a senior Platform Security Engineer to strengthen cloud security, platform reliability, and secure engineering practices in a fully remote European environment. In this individual contributor role, you will join a platform engineering team focused on building reliable infrastructure and improving the developer experience. You will design and implement secure-by-default workflows that protect sensitive personal and compensation data across multiple countries. Your work will span cloud infrastructure, Kubernetes, CI/CD security, identity management, observability, and disaster recovery. You will collaborate closely with engineers to embed security into everyday workflows without compromising delivery speed or usability. By combining hands-on engineering, automation, and pragmatic risk management, you will help build a resilient platform where security becomes the easiest path. This is an opportunity to shape platform security strategy while delivering measurable improvements in a collaborative, remote-first team. Accountabilities: As a Platform Security Engineer, you will take ownership of production security improvements while contributing to the broader platform engineering roadmap. You will focus on practical solutions that improve security, reliability, and developer productivity. - Design and implement secure-by-default workflows for production operations, ensuring access is controlled, auditable, and straightforward for engineers to use. - Strengthen cloud security practices, including identity and access management, SSO/OIDC, secrets management, and least-privilege access controls. - Secure and operate production Kubernetes environments, implementing appropriate workload security and access restrictions.

- Integrate security checks and automated scanning into CI/CD pipelines to identify and resolve vulnerabilities early in the delivery process. - Improve infrastructure-as-code practices, developer tooling, and self-service guardrails to make secure engineering workflows easy to adopt. - Manage cloud networking and edge protection, including VPC boundaries, DNS, TLS, load balancing, CDN, and Web Application Firewall (WAF) configuration. - Define and improve security priorities, response targets, incident workflows, threat modeling, and post-incident reviews. - Strengthen platform reliability through service-level objectives (SLOs), observability, on-call practices, and incident troubleshooting. - Design, implement, and regularly test backup, restoration, and disaster recovery procedures to support business continuity. - Lead resilience exercises and refine recovery playbooks to ensure recovery objectives are clear and achievable. - Use AI-powered engineering tools and automation, including agents and Model Context Protocol (MCP) integrations, to accelerate engineering work and improve platform operations. - Collaborate with platform engineers and engineering leadership to balance risk, delivery speed, developer experience, and operational stability. - Document technical decisions, communicate trade-offs clearly, and use feedback and adoption metrics to continuously improve platform security. Requirements: You should be a hands-on platform engineer with strong production security expertise and the ability to turn security requirements into practical, measurable improvements. Evidence of what you have built, improved, and influenced is more important than a specific number of years of experience. - Demonstrated ownership of application or platform security in a production cloud environment, with clear examples of impact. - Strong cloud security fundamentals, including IAM, SSO/OIDC, secrets management, identity integrations, and least-privilege access.
