Sr. DevSecOps Engineer

Full Time JOB SUMMARY We are seeking a Senior DevSecOps Engineer to operate the cloud infrastructure our engineering teams depend on today and to build its successor from the ground up. The current environment spans AWS, Kubernetes, and CI. The next one is a new AWS GovCloud organization defined entirely as code, with the networking, identity, and software supply chain that a regulated engineering organization needs. You will keep the existing environment healthy while the new one takes shape, then move workloads into it. You will also run the tooling that gives our engineers governed access to AI models and coding agents. This is a building role on a small team, and the scope is broad by design. You will not maintain a compliance binder; you will turn security requirements into code that produces its own evidence. Key Responsibilities Operate and improve our existing AWS environments, Kubernetes clusters, and CI platform, and migrate workloads into the new organization as it comes online Build a new multi-account AWS GovCloud organization as code Build and operate segmented network planes: Transit Gateway, Firewalls, IPAM, PrivateLink, and VPNs to our facilities Deliver secure environment ingress / egress Own the software supply chain from commit to cluster: CI/CD runner fleets, FIPS-validated images, signed artifacts, replicated registries, private PKI Partner with security and compliance to translate NIST SP 800-171 and CMMC controls into automated guardrails and evidence, and to triage and burn down security findings Write clear design notes, merge request reviews, and runbooks, and help improve the shared AI-assisted workflows the team uses every day Roll out and support AI developer tooling (Claude Code and similar) with managed settings, and review, harden, and operate the MCP servers and agent runtimes our teams depend on Required Skills and Experience Production Terraform or OpenTofu: reusable modules, state management, imports and refactors, and careful plan review Proficiency in Python and/or Go, plus shell scripting Clear, concise technical writing Deep hands-on AWS experience in a multi-account organization: IAM policy evaluation, Organizations and service control policies, and Identity Center or equivalent federation with an external IDP Cloud networking you can debug under pressure: VPC design, Transit Gateway routing and segmentation, firewalls and inspection, DNS, PrivateLink, and site-to-site VPN with BGP; you can answer “why can’t X talk to Y” across accounts CI/CD and container supply chain experience, including image builds, signing and verification, secrets management, and vulnerability scanning Hands-on experience running access to a hosted model service (Amazon Bedrock, Azure OpenAI, Vertex AI, or similar) or an LLM gateway Experience with AI coding agents (Claude Code or equivalent), with a working understanding of its risks: prompt injection, excessive agency, token and secret exposure, and untrusted tool servers Desired Skills and Experience AWS GovCloud experience, or work inside FedRAMP, NIST SP 800-171, CMMC, or ITAR-controlled environments Greenfield landing-zone or account-vending work, including AWS Network Firewall and IPAM Private PKI (for example AWS Private CA), HSM-backed key management, and mTLS Service mesh (Istio or similar) and GitOps tooling (Argo CD, Flux, or similar) LLM gateway operations (LiteLLM or equivalent), per-user cost attribution, and model invocation logging Building or securing MCP servers and agent workflows Shared AI workflows you built that other engineers adopted: hooks, commands, rules files, skills, or agent pipelines Operating Kubernetes in production, preferably EKS FIPS 140-3 validated cryptography and hardened container images Experience in aerospace, defense, or other export-controlled programs Education & Work Experience BS in Computer Science, Computer Engineering, or a related field, or equivalent practical experience 7+ years in infrastru…
