- Hybrid About Cloud Bees Cloud Bees  helps organizations build, run, and govern software factories, giving enterprises the confidence to ship software better, faster, and safer.

Writing code is no longer the bottleneck. Governing what reaches production and validating its impact is. As enterprises adopt agentic coding, software is created faster than most teams can review, secure, and validate. Without consistent governance, organizations risk shipping code they cannot explain, audit, or trust.

Cloud Bees addresses this challenge without asking teams to replace the tools they already use. Across every toolchain a customer runs, Cloud Bees makes each change, human or AI, visible, auditable, and accountable before it reaches production. Cloud Bees Unify is the product behind this: a governance layer, with context and control-plane capabilities, that enforces consistent policy and evidence across every tool, team, and workflow.

Founded in 2010, Cloud Bees is backed by Goldman Sachs, Morgan Stanley, Bridgepoint Capital, HSBC, Golub Capital, Delta-v Capital, Matrix Partners, and Lightspeed Venture Partners.

Visit us at .About the Role We're looking for a motivated engineer to help secure the most critical AI initiatives across the business.

Most application security engineers spend their careers on the product side. This role puts you on the other side: AI-era security for the business itself, not the product customers use. You'll work alongside the CISO on problems most companies don't have a playbook for yet.

The work is product security with an enterprise scope. Internal apps, AI tools, and agents are products that need the same threat modeling, secure design, and engineering rigour as anything customer-facing.

Alongside enterprise security work, you'll build tooling, automation, and agents that help the broader security team scale with AI.You're curious, proactive, and hands-on. We'll back you with the resources and exposure to do your best work.

This is a hands-on role. Bring initiative. We'll give you the problems worth solving.
