Rescale is pioneering the future of engineering and scientific discovery. As the leader in digital engineering, we’re transforming how products are developed—through intelligent automation, applied AI, data management, and the integration of the world’s largest network of engineering and R&D applications. Joining Rescale means becoming part of a diverse, collaborative, and mission-driven team that’s unlocking faster innovation across industries like aerospace, energy, life sciences, and manufacturing. We’re solving complex challenges that traditional HPC can’t—and we’re seeking passionate, curious minds to help build the next wave of breakthroughs. We’re hiring a Senior Cloud Security Engineer to help secure the cloud infrastructure, identity systems, and internal tooling that our platform and our company run on. You’ll work across AWS, Okta, GitHub Enterprise, and increasingly AI-assisted and agentic tooling our employees use daily. This is a hands‑on role: you’ll be writing Terraform, querying logs, and designing IAM policy, not just reviewing other people’s work.

What You’ll Work On

• Design, build, and harden cloud infrastructure and identity systems
• Build and maintain security automation and detection pipelines
• Evaluate and help secure the growing set of AI‑assisted and agentic tools used internally (e.g., Claude Code, MCP servers, LLM‑driven automation)
• Investigate and respond to security findings, including triaging authentication anomalies, reviewing access logs, and querying data via tools like Athena, CloudTrail Lake, or Superset.
• Contribute to Infrastructure-as-Code (Terraform) for security controls, identity provisioning, and compliance‑relevant configuration and monitoring.
• Support secure network and cloud deployment designs for enterprise customer environments, partnering with engineering and customer‑facing teams on requirements.
• Research emerging cloud‑native and AI security capabilities (including AI‑enabled attack techniques) and translate findings into practical controls and internal guidance.
• Write internal documentation, runbooks, and playbooks to scale security practices across the team.

What We’re Looking For

• 5+ years of experience in cloud‑native security or DevSecOps.
• 3+ years of experience with Bash or Python.
• Deep, hands‑on experience with a major cloud provider (AWS, Azure, GCP, or OCI.
• Experience with Infrastructure-as-Code (Terraform or similar) and identity/access management platforms (Okta, Azure AD, or similar).
• Real exposure to at least one of: OAuth/token architecture, AI/LLM-assisted tooling security, or agentic workflow design
• Solid understanding of operating systems and networking fundamentals.
• Bachelor’s degree in Computer Science or related field, or equivalent practical experience, but not required if you have the experience above.
