IonQ is the world's leading quantum computing platform and merchant supplier, delivering integrated quantum solutions across computing, networking, sensing, and security. The company operates globally with headquarters in College Park, Maryland, and offices across North America, Europe, and Asia.
The Platform Engineering team builds, secures, and operates scalable infrastructure supporting cloud-managed SaaS products with on-premises components deployed at customer sites. As Staff DevSecOps Engineer, you will provide technical leadership for the software factory, defining how software is built, secured, and released across the organization.
You will own the roadmap, architecture, and tooling that enable every engineering team to deliver software securely, consistently, and at scale, while remaining hands-on with automation, infrastructure, and platform engineering. Working closely with Architecture, Site Reliability Engineering, Cloud Operations, and Product Development teams, you will drive an automation-first culture where secure software delivery, developer experience, and operational excellence are embedded into every stage of the software lifecycle.
Key responsibilities include defining and evolving the software factory (CI/CD platforms, release engineering, developer tooling, Infrastructure as Code, dependency management, and software supply-chain security); delivering secure-by-default engineering practices through automated security controls, policy enforcement, vulnerability management, and compliance automation; mentoring engineers and establishing engineering standards; and leading the design, implementation, and operation of the organization's DevSecOps platform.
You will develop reusable CI/CD pipelines, Infrastructure as Code modules, and self-service developer capabilities that improve productivity while maintaining the highest security standards. You will own release management, dependency and supply-chain security, security operations, and hybrid infrastructure consistency across cloud and on-premises environments. You will also drive adoption of agentic automation and AI-enabled workflows to reduce manual effort, improve operational efficiency, and enhance software delivery.
