Job summary

OLIX seeks a senior infrastructure engineer to own and improve the internal platform used by engineering teams, covering compute, storage, networking, CI/CD, and security. This hands-on role focuses on fast, reproducible workflows and a secure, scalable environment across hybrid cloud and on-prem resources.

You'll automate with Terraform and CI/CD pipelines, collaborate with hardware and ML engineers, and drive reliability and security across the stack.

Qualifications

• 5+ years in infrastructure, platform, or DevOps/SRE engineering, with a track record of owning systems end to end.
• Strong infrastructure-as-code and automation skills: Terraform, Ansible, and scripting in Python and Bash.
• Solid networking fundamentals.
• Experience operating across hybrid cloud and on-prem/bare-metal environments.
• Strong grasp of infrastructure security: IAM, secrets management, network security, and hardening across cloud and self-hosted systems.
• Excellent problem-solving skills, with the ability to diagnose and resolve complex, cross-layer issues in a fast-moving environment.
• A collaborative communicator who can work with hardware and ML engineers and explain infrastructure trade-offs clearly.
• Bachelor's degree in computer science, a related field, or equivalent practical experience.

Responsibilities

• Build and operate the platform: design, provision, and run the Kubernetes and bare-metal infrastructure that powers development, simulation, and testing workloads.
• Automate everything: own infrastructure-as-code (Terraform) and provisioning pipelines so environments are reproducible, version-controlled, and fast to stand up or tear down.
• Improve the developer platform: build and maintain CI/CD, internal tooling, and self-service workflows that let hardware, software, and compiler engineers ship without waiting on you.
• Tune for performance: optimise networking (VLANs, firewalls, VPNs, and low-latency/high-bandwidth fabrics) and storage for the throughput and latency that ML and hardware workloads require.
• Own reliability and observability: implement monitoring, alerting, and capacity planning, and drive availability and performance across hybrid cloud and on-prem environments.
• Own platform security: implement identity and access management, secrets management, data protection, and threat detection across self-hosted and cloud infrastructure.
• Drive continuous improvement: proactively find and fix the bottlenecks, manual steps, and reliability gaps that slow the wider engineering team down.
