Experience disruption-proof digital banking with Lumin Digital's cloud-native Compounding Growth Platform, offering innovative solutions for financial institutions.
About the role
Build and operate Lumin's security fabric: the foundation other security capabilities depend on, engineered for reliability and scale across hundreds of environments. Build and maintain agentic AI workflows using tools like Claude Code, MCP-based integrations, and custom agent harnesses to automate security platform engineering tasks. Examples include infrastructure code review, configuration drift detection, runbook generation, and incident timeline synthesis.
What they're looking for
- 5+ years of hands-on experience in platform engineering, infrastructure engineering, reliability engineering, DevSecOps, or a closely related technical discipline, 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 operating cloud-native infrastructure in production, with deep familiarity in AWS, Kubernetes, multi-account / multi-region patterns, and CI/CD pipeline integration
- Experience with security telemetry platforms (OpenSearch or similar), GitOps deployment patterns (ArgoCD, Argo Workflows, Kustomize, or similar), or reliability engineering practices in a security or compliance-sensitive context 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 Security Platform Engineer, you will apply reliability engineering to our security-critical infrastructure: building systems that scale gracefully, recover automatically, and converge on correct operation across hundreds of environments. Your scope spans telemetry clusters, GitOps-driven deployment workflows, and the patterns that make security a paved path for the rest of engineering. 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 Platform and Reliability Engineers who treat AI as part of their working medium and have something to teach the rest of us about reliability in an AI-native world. Success means our security fabric scales without us, and our on-call rotations get quieter every quarter.
