Olix Computing builds optical AI accelerators from London, combining photonics with an SRAM-based memory architecture. They're hiring an Infrastructure Engineer in London to build the compute and tooling its chip teams depend on, working on-site. This software engineering role sits within the UK's semiconductor and photonics sector.
AI is growing faster than any technology in history and the explosion in demand has created a massive infrastructure gap; we can no longer build chips or power stations fast enough to keep up. The industry is still leaning on a ten-year-old hardware blueprint that has reached its limit. A new paradigm that is faster and more efficient will be the biggest economic opportunity of the next century and create the most important company of the next decade. The OLIX Decode Accelerator 1 (DX-1) is the first accelerator architected specifically for decode. Rack-scale co-design of logic, data movement, packaging, optics and interconnect enables a step change in system level performance.
We're hiring a senior infrastructure engineer to own the internal platform our engineering teams build, test, and collaborate on, spanning compute, storage, networking, build and CI/CD systems, and the security that protects all of it, while partnering with our IT function on identity, devices, and access across the company. You'll turn slow, manual, loosely secured workflows into fast, reproducible, and genuinely secure ones. This is a hands-on, high-ownership role with the freedom to define how internal infrastructure, security, and the technical side of IT work here from the ground up. If you care about engineering velocity, solid networking, best-in-class security, and a well-run technical environment in equal measure, there's a lot to dig into.
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.
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.
Competitive Salary: Commensurate with your experience, skills, and location
Equity & Ownership: Meaningful stock options. You’re not just joining the mission; you’re owning a piece of it
Proximity Bonus: We value your time. To minimise your commute and maximise your life, we offer an annual Living-Local Bonus if your residence is within 20 minutes of the office
Retirement Benefits: Employer-contributed retirement plans to help you build long-term financial security.
Due to U.S. export control regulations, candidates’ eligibility to work at OLIX depends on their most recent citizenship or permanent residency status. We are generally unable to consider applicants whose most recent citizenship or permanent residence is in certain restricted countries (currently including Iran, North Korea, Syria, Cuba, Russia, Belarus, China, Hong Kong, Macau, and Venezuela). Applicants who have subsequently obtained citizenship or permanent residency in another country not subject to these restrictions may still be eligible.
Olix Computing is a London-based startup developing the Optical Tensor Processing Unit (OTPU), a new type of AI accelerator that uses photonics rather than traditional GPU architecture for AI inference. The company integrates photonics with an SRAM-based memory architecture, which it claims can outperform high-bandwidth memory systems in efficiency, throughput per watt, and overall cost. Originally registered as Flux Corp Ltd in March 2024, the company rebranded to Olix Computing. Founded by 25-year-old serial entrepreneur James Dacombe, who also runs brain-monitoring company CoMind, Olix has grown to over 70 employees and plans to ship its first products by 2027. Valued at over $1B.
