Join Onyx Security and help build the control plane for autonomous AI in a fast-moving, high-impact environment. Onyx is building the control layer that enables enterprises to safely adopt and scale AI agents across the organization, with the visibility, governance, and operational control needed to understand what agents exist, what they do, how they behave, and what risks they introduce.
About the role
We're looking for an all-round infrastructure engineer who writes production-grade code, designs systems from first principles, and owns everything from infrastructure-as-code to a multi-cloud ML serving stack. You'll be joining a small, elite infrastructure team that owns it all.
What you will do
- Lead infrastructure architecture across the company and take end-to-end ownership across Onyx's infrastructure - cloud environments, platform tooling, internal services, and production uptime
- Design and build production-grade services and internal platform tooling; you write code at the same bar as the product engineering team
- Operate and scale AI/ML Serving Infrastructure systems behind real-time LLM routing, model inference, and AI security enforcement in production
Requirements
What you will bring
- 6+ years in infrastructure, platform, DevOps, or SRE roles - with strong software engineering ability, not just operational experience
- Production-grade cloud expertise (AWS, GCP or Azure) - deep understanding of compute, networking, data services, identity, and security across cloud providers
- Hands-on experience building and running AI/ML infrastructure in production - model serving, inference workloads
- Kubernetes depth - you operate clusters in production, understand the internals, and debug the problems others escalate
- Infrastructure-as-code at scale - you've designed module architectures, managed state across environments, and integrated it all into CI/CD
- Experience building an internal developer platform - you've designed the tooling, pipelines, and abstractions that engineering teams depend on
- Strong coding ability in Go, Python, or Node.js - you build and own services, not just glue scripts
- Security-first thinking embedded in how you design and operate systems
