Build and automate infrastructure using Terraform and Kubernetes, optimize performance for ML workloads, and ensure security and reliability across hybrid cloud and on-prem environments. ## Job description ## ABOUT OLIX 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. ## THE ROLE 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. ## 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. ## SKILLS & EXPERIENCE - 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. ## COMPENSATION & EQUITY - 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. ## About OLIX ## Company Overview - **One-liner**: OLIX, formerly known as Flux, is building a new compute paradigm using an SRAM-architecture integrated with photonics to solve the fundamental memory, energy, and speed constraints in deploying frontier AI. - **Entity Type**: Private, Series A (raised $220M in February 2026) - **Headquarters**: London, United Kingdom - **Founded**: 2024 - **Founders**: James Dacombe (CEO) ## Core Business - **Primary industry/industries**: Semiconductor Manufacturing, AI Infrastructure, Photonic Computing - **Target customers**: Enterprise AI labs, hyperscalers, and frontier AI model developers requiring high-throughput, low-latency compute - **Mission or purpose statement**: "Solving the most consequential problem in the deployment of frontier AI" by building infrastructure that overcomes the limits of current GPU-based memory architecture. ## Products & Services - **OLIX Compute Platform**: A new hardware architecture combining SRAM-based compute with integrated photonics, designed to surpass HBM-based systems on throughput per megawatt and total cost of ownership (TCO), while delivering significantly better interactivity and latency than silicon-only SRAM architectures. ## Market Standing - **Valuation**: Unicorn status; estimated $1–2.5B (latest round Feb 2026, per Dealroom) - **Key Metric**: $220M in total funding (Series A, led by Hummingbird Ventures, with participation from Crane Venture Partners and others) - **Notable Investors/Partners**: Hummingbird Ventures (Series A lead), Crane Venture Partners (pre-seed lead), and 4+ additional investors across seed and Series A rounds. - **Growth Signals**: Headcount grew 420% YoY to 70 employees; operating in 6 countries (UK, US, Canada, Armenia, Romania, Germany); active job postings surged 188.9% YoY with 26 open roles as of mid-2026. ## Competitive Advantages - **Unique photonic-SRAM architecture**: A contrarian bet that GPU-based approaches cannot simultaneously deliver high throughput and high interactivity at low cost due to physical design constraints. - **Talent density**: Heavy hiring from top compute and AI companies (Apple, Amazon, Arm, Google, Tenstorrent). - **First-mover in inference-era compute**: Targeting a fundamental bottleneck as frontier models require vastly more tokens per inference. ## Strategic Focus - **Scale teams**: Aggressively hiring across engineering (ASIC/photonic design, FPGA, optics, process integration), operations, and legal in London, Austin, Toronto, Bristol, and San Francisco. - **Prototype and productize**: Moving from architecture conception into hardware integration and manufacturing (roles include Process Integration Engineer, Opto-Mechanical Engineer, Layout Engineering Manager). - **Transition from Flux branding**: Rebranded to OLIX in January 2026 to signal a new phase of company identity and scale. ## Why Work Here - **In-person culture**: OLIX is an in-person company. They incentivize living within a 20-minute commute of the office with a £24,000 annual living-local bonus. - **Compensation**: Benchmark-leading base salary, meaningful stock options (early employees build significant ownership), and workplace pension. - **Benefits**: Comprehensive BUPA medical & dental (with Medical History Disregarded), 25 days holiday + UK bank holidays + birthday leave, meals on-site, cycle-to-work scheme, nursery scheme, visa sponsorship and relocation support. - **Engineering environment**: M4 Mac standard (M5 Pro upgrade for engineering), on-site 3D-printing lab, noise-cancelling headphones, fully ergonomic workstation, and a culture of deep focus. - **Impact**: "You will work with some of the best minds in photonics, systems, and compute on one of the defining problems of our era." ## Sources 1.
