Experience disruption-proof digital banking with Lumin Digital's cloud-native Compounding Growth Platform, offering innovative solutions for financial institutions.
About the role
Engineer the security infrastructure the rest of the company depends on across AWS and Kubernetes: telemetry pipelines, cryptographic material lifecycle, compliance automation, and the architecture patterns that scale across hundreds of environments.
What they're looking for
- 5+ years of hands-on experience in security engineering with a strong emphasis on building engineered systems rather than operating manual processes
- At least 1 year of production experience with at least 2 agentic coding tools, such as Claude Code, Gemini, Cursor, Codex, AMP, or OpenCode
- Demonstrated experience building and shipping production code in Python or a similarly capable language, with infrastructure-as-code tools such as Terraform
- Proven track record of working in cloud-native environments, with deep familiarity in AWS, Kubernetes, containerized workloads, and CI/CD pipeline integration
- Experience with security telemetry platforms (OpenSearch or similar), PKI / certificate lifecycle management, or compliance automation preferred
- Hands-on experience shipping at the agentic tool layer: MCP integrations, custom agent harnesses, or AI tool-use pipelines
More about this role
Lumin Digital's Security Engineering team is a true engineering organization that protects a cloud-hosted digital banking platform serving financial institutions and their members. As a Cybersecurity Engineer, you will build software and infrastructure that heals itself, automatically enforces controls at scale, and converges on correct operation across hundreds of environments. Your scope includes the lifecycle of our cryptographic material and the architecture of our security telemetry. You will work in AI-assisted engineering tools every day: agentic coding assistants like Claude Code, MCP-based integrations, and custom agent harnesses. This role exists for engineers fluent in AI tools who have something to teach the rest of us about working with them. Success means our security infrastructure doesn't go bump in the night.
