Senior / Staff Platform Security Engineer
Colossus Technologies Group is partnering with a rapidly growing financial technology company to build out a highly technical Platform Security organization.
We’re looking for security-minded software engineers who want to build the systems, tooling and guardrails that secure a large-scale cloud production environment.
This is not a traditional cloud security or DevSecOps position. The strongest candidates will be engineers who can write production software, understand cloud infrastructure deeply and build security capabilities rather than simply configure security products.
What you’ll work on:
- Building security services and internal tooling in Python and/or Go
- Securing large-scale AWS environments and cloud-native infrastructure
- Kubernetes and container security
- IAM, authentication, authorization and least-privilege architecture
- Infrastructure-as-code security and automated policy enforcement
- Security controls embedded into CI/CD and engineering workflows
- Vulnerability detection, prioritization and automated remediation
- Developing scalable security guardrails for engineering teams
- Applying AI and automation to cloud security, vulnerability management and detection
- Designing security systems that are reliable enough to operate as production infrastructure
What we’re looking for:
- Strong software engineering fundamentals
- Production experience with Python, Go or another modern backend language
- Deep AWS or comparable cloud infrastructure experience
- Experience building security systems, platforms or automation
- Understanding of distributed systems and production infrastructure
- Experience with Kubernetes, containers and modern deployment environments
- Terraform or comparable infrastructure-as-code experience
- Ability to own a technical problem from architecture through production
We’re particularly interested in engineers coming from:
- Platform or infrastructure security
- Cloud security engineering
- Security-focused backend/software engineering
- Infrastructure engineering with significant security ownership
- Security product engineering
