Mechanical Engineer

About OLIXAI 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 RoleWe are seeking an experienced and highly motivated Mechanical Engineer to design and develop the mechanical systems at the heart of our next-generation compute platforms, from concept and architecture through prototype builds, qualification, and production release.You will work on high-performance, thermally demanding hardware: chassis, cooling integration, rack-scale infrastructure, and complex electromechanical assemblies and collaborating closely across Electronics, Optical, Systems, Software, Manufacturing, and Quality teams.The ideal candidate owns mechanical architecture end to end, balances thermal, structural, and manufacturability trade-offs with confidence, and thrives building breakthrough infrastructure in a fast-moving environment.ResponsibilitiesOwn the mechanical architecture of assigned products and subsystems including: chassis, enclosures, structural assemblies, cooling systems, and rack-integrated hardware. Driving these products from concept through validation, production release, and lifecycle supportDesign solutions that balance thermal performance, mechanical robustness, serviceability, manufacturability, scalability, and costCreate detailed CAD models, engineering drawings, bills of materials, and technical documentation, applying GD&T and DFM/DFA/DFR/DFS principles throughoutDrive thermal management strategies including airflow optimisation, liquid cooling integration, cold plates, and system-level heat rejectionDefine mechanical interfaces between compute, networking, power, optical, and cooling subsystems, and contribute to rack-level integration (structural design, service access, cable and airflow management)Conduct and interpret mechanical, thermal, airflow, and structural analysis (FEA/CFD) to support design decisionsSupport product development from prototype builds and EVT/DVT/PVT through qualification testing and production releaseLead root cause analysis and corrective actions for mechanical, thermal, manufacturing, and integration issuesWork with suppliers and contract manufacturers on component qualification, tooling, manufacturability, and cost optimisationCollaborate across multidisciplinary engineering teams and lead design reviews and system architecture discussionsSkills & ExperienceDegree in Mechanical Engineering or a related discipline, with strong experience developing complex electromechanical products from concept through productionDemonstrated ownership of mechanical systems, chassis, or infrastructure across the full product lifecycleExperience designing products incorporating dense electronics, optical subsystems, networking, or compute hardware with demanding thermal and power-density
