Senior Platform Engineer

Introduction to the Role

Are you ready to design secure, plug-and-play platform capabilities that enable engineering teams to build and deliver software safely at speed?

As a Senior Platform Engineer, you will be a senior DevSecOps builder responsible for designing and delivering Golden Pipelines, reusable infrastructure modules, GitHub Actions workflows, and standardized templates. You will turn complex requirements into secure, scalable capabilities that allow product teams to focus on their applications rather than the underlying engineering foundations.

You will act as a subject-matter expert and technical lead, guiding complex designs and helping other engineers grow their capabilities. This is a hands-on senior individual contributor role without formal people-management responsibilities.

Accountabilities

• Golden Pipelines and Templates: Design and deliver secure, compliant Golden Pipelines, GitHub Actions workflows, and reusable infrastructure templates for enterprise use.
• Terraform Module Engineering: Design and build modular, scalable, secure, and reusable Terraform modules using advanced Infrastructure as Code patterns.
• DevSecOps by Design: Embed SAST, DAST, SCA, software bill of materials generation, supply-chain security controls, and protections against pipeline threats.
• Secure Architecture: Lead technical design across serverless, container, compute, networking, and hybrid environments.
• Secure CI/CD Patterns: Define and implement secure CI/CD patterns that can be adopted consistently across engineering teams.
• Automation and Tooling: Build automation and internal tooling using Python or Go, applying appropriate testing and software-engineering practices.
• Testing and Quality: Define and implement testing strategies for Infrastructure as Code, scripts, and automation, using tools such as Terratest where appropriate.
• Technical Leadership: Guide Platform Engineers, review designs and technical work, and help the team make secure, scalable engineering decisions.
• Documentation and Enablement: Produce clear architecture diagrams, technical documentation, and implementation guidance that enable teams to use platform capabilities effectively.
• AI and Innovation: Apply AI tools responsibly to accelerate development, testing, security analysis, and secure design while improving platform quality and delivery speed.

Essential Skills and Experience

• Strong experience designing and building enterprise platform or DevSecOps capabilities.
• Strong experience with AWS across serverless, compute, networking, and security services.
• Advanced expertise in Terraform and Infrastructure as Code design patterns.
• Strong programming or scripting skills in Python or Go, including testing practices.
• Deep understanding of DevSecOps practices, including:
  • SAST, DAST, and SCA
  • Software bills of materials and supply-chain security
  • Secure CI/CD pipeline design
• Experience implementing least privilege and security-by-design architectures.
• Strong knowledge of cloud security, networking, and system design.
• Experience building scalable, reusable, and non-monolithic solutions.
• Ability to lead complex technical work and guide engineers without formal management authority.
• Strong technical communication and documentation skills.

Desirable Skills and Experience

• Kubernetes and container-orchestration experience.
• Hybrid or on-premises architecture experience.
• Azure exposure.
• Knowledge of modern application stacks such as Java, .NET, or React.
• Experience with Terratest or comparable Infrastructure as Code testing tools.
• Experience applying AI tools to development, testing, and secure design.

What Success Looks Like

• Secure, reusable, and scalable platform templates are delivered and widely adopted.
• Security controls are embedded by default across platform solutions.
• Security risks and configuration errors are reduced across engineering teams.
• Platform capabilities are compliant, developer-friendly, and easy to consume.
• DevSecOps capabilities and platform offerings continuously improve.
• Other engineers benefit from effective technical guidance and increase their ownership over time.
