• Job Summary
• As a Senior Software Engineer on the Cloud Security Engineering team, you will design, build, and operate reliable software platforms that transform complex business and technical findings into clear actions teams can take.

This is a senior software engineering role in the cybersecurity space, with opportunities to apply AI where it provides practical value.

You will build systems that ingest information from multiple internal and external tools, apply business logic, and turn that information into workflows, recommendations, automation, and measurable outcomes. You will also help us develop agentic pipelines that coordinate tools, data, and multi-step processes. Prior AI experience is not required. We are looking for a strong engineer who can learn quickly, evaluate new technologies, and apply them thoughtfully.

This is a senior, high-impact engineering role where you will own major technical areas end-to-end. You will design systems of significant complexity, write production-quality code, make sound architectural trade-offs, and lead implementation across services, data flows, workflow automation, and agentic pipelines. You will be expected to reason from first principles, break down ambiguous problems, learn unfamiliar tools quickly, and deliver durable software that can be operated in production.
