Role

Who you are

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

What the job involves

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
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 play

Our take

Migrating on-premises infrastructure to a hybrid or fully cloud-based setup is a complex process that requires network understanding, resources, and time. Whilst some companies aid in making this switch simpler, the challenges of migrating high-performance computing (HPC) systems to the cloud are significantly more complex and remain unaided.

Rescale provides sets of HPC resources to help customers optimise their applications for maximum performance within hybrid or fully cloud-based infrastructures. This is achieved through the application of full-stack automation to minimise the complexity of migration, fine-tuning the infrastructure to optimise the performance of the specific application.

Various startups are tackling infrastructure migration for small businesses and enterprises to support industry-wide moves to cloud computing. Rescale presents itself as a unique competitor by focusing on aiding companies that require HPC for industries such as engineering, aerospace, and scientific research. Impressive 2025 funding will be used to accelerate the development of Rescale's digital engineering platform, and comes at a time when more companies are investing in technology that quickens their products' time to market.
