Job Summary

As a Software Engineer 3 on the Cloud Security Engineering team, you will design, build, and operate software platforms that help turn cloud security-related data into clear actions teams can take. The work sits in the cybersecurity space, but this is primarily a software engineering role focused on backend systems, data pipelines, workflow automation, cloud infrastructure, and production service ownership. 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. These platforms help teams investigate issues, understand next steps, automate intermediate work, and implement repeatable processes across engineering organizations. This is a high-impact engineering role where you will own meaningful technical areas end-to-end. You will design systems of medium complexity, write production-quality code, make sound technical trade-offs, and contribute across services, data flows, and workflow automation. You will be expected to break down ambiguous problems and deliver durable software that can be operated in production. You will work closely with software engineering teams, platform teams, product partners, and security stakeholders to translate unclear problem spaces into usable internal products. Successful candidates bring strong engineering
