About the Team

We aren’t looking for someone to monitor dashboards or hunt for alerts—we need the engineer who builds the "observatory" itself. As a member of our Platform Security Engineering team, you will be responsible for the architecture, engineering, and maintenance of the systems that protect the Workday product.

Operating entirely within AWS, you will treat "Security as Code," ensuring our Vulnerability Management, SIEM, and SOAR tools are robust, scalable, and automated. You are the primary engineering partner to our SOC, building the high-fidelity tools they rely on to keep our customers safe.

About the Role

This role will support one or more direct or indirect contracts with the U.S. Federal Government which, due to federal government security requirements, mandates that all Workday personnel working on the contracts be United States citizens (naturalized or native).

• Design and maintain the lifecycle of our core security stack (Vulnerability Management, SIEM, and SOAR) in a native AWS environment.

• Secure, manage, and monitor Kubernetes clusters and containerized workloads. You’ll ensure our tooling scales alongside our containerized infrastructure.

• Use tools like Terraform, CloudFormation, or CDK to deploy and manage security infrastructure, ensuring our environments are version-controlled and immutable.

• Leverage Python to bridge the gaps between commercial tools. When a tool hits its limit, you build the integration or custom logic to fix it.

• Actively use AI tools and LLMs as a "force multiplier" to accelerate development, optimize code, and automate repetitive tasks.

• Transform complex security telemetry into actionable, visual insights. You’ll build dashboards that show our partners exactly where we stand and where the gaps remain.

• Work to integrate security tooling into the developer workflow, ensuring our engineering is as agile as the product it protects.

About You

This role may require a security clearance at the TS/SCI w/CI Poly level. Applicants must have the ability to obtain and maintain a U.S. government issued security clearance. An active TS/SCI w/CI Poly is preferred.

You are a highly organized, technically fluent program leader who thrives in complex, fast-paced environments, managing ambiguity, aligning stakeholders, and driving execution. You balance technical understanding with program management expertise to anticipate risks and maintain momentum. You break down complex problems into actionable plans and possess a proactive, ownership-driven, and results-focused mindset.

May be required to be on site at client locations in the DC, MD, and VA (DMV) area

• You don’t over-engineer for the sake of complexity. You choose the most reliable, scalable path to get the job done and hate manual repetition.

• You don’t wait for a ticket to fix a glaring gap. You see a problem, research it from first principles, and propose the solution.

• You excel in the "gray area." If you’re dropped into a problem set you’ve never seen before. Whether it's a new K8s vulnerability or a custom API, you have the intellectual agility to figure it out and deliver.

• You treat the organizational partners as your customer. Your success is defined by how well your tools empower them. You take the time to understand their goals so you can better serve them.
