Top Tech Jobs & Startup Jobs

Design and build end-to-end software primitives for AI infrastructure: domain modeling of power/datacenters/chips, authorization, audit, orchestration, vendor data ingestion (KMZ/BIM/Revit), and agent integration to enable safe, auditable agent operators. Ship production-quality systems and work across ambiguity to turn unstructured data into durable, composable entities.

Design end-to-end datacenter network architectures for AI training and inference: topology, IP/routing, RDMA/lossless fabrics, physical integration (rack, power, cabling), and comprehensive HLD/LLD documentation. Collaborate with hardware, operations, cabling, software, and validation teams to produce deployable, scalable, and performance-validated designs.

Own Fluidstack’s global insurance programs across property, construction, liability, and cargo. Manage broker and carrier relationships, renewals, budgets, claims, loss control, property risk engineering, exposure data, and contractual insurance requirements. Coordinate with Legal, Construction, HSE, Data Center Operations, TPAs, adjusters, and executives to resolve claims, close risk gaps, and maintain compliant, audit-ready coverage as the company scales its data center infrastructure.

Serve as a people partner for client organizations while owning the company’s immigration and visa sponsorship program. Manage immigration cases and outside counsel, handle employee relations investigations, run onboarding and performance processes, and coach managers through rapid organizational growth. The role requires expertise with employer-sponsored immigration programs, HR business partnering, employment law, and sensitive employee relations matters.

Provide hands-on IT support for in-office and remote employees, manage macOS, iOS, and Windows devices, administer Okta and SaaS tools, and maintain identity and access controls. Own hardware procurement, asset lifecycle tracking, onboarding, and offboarding. Troubleshoot network and A/V systems, build automations, conduct access reviews, and create clear technical documentation.

Design and validate thermofluids systems for large-scale AI data center cooling. Responsibilities include developing cycle models, selecting working fluids, designing heat exchangers and piping, sizing valves and relief systems, analyzing coupled thermal and fluid trades, and validating predictions against test-stand data. The role requires rigorous model calibration, honest reporting of discrepancies, and technical analysis that drives machine design decisions.

Own control architecture for rotating machinery and test rigs, including compressors, motor drives, expansion turbines, and thermofluid loops. Develop safety interlocks, fault handling, speed-based capacity control, and hardware-in-the-loop validation. Tune controls on live machines, investigate model-to-plant discrepancies, integrate production chillers with site BMS and plant systems, and document systems for operations teams.

Own compressor testing from test-cell commissioning through validated performance mapping. Responsibilities include specifying test cells and instrumentation, defining measurement chains and uncertainty budgets, writing test plans and safety interlocks, analyzing data, supporting design changes, and conducting failure investigations. The role focuses on high-pressure, high-speed rotating machinery, thermofluids, refrigeration performance, and data acquisition.

Owns end-to-end aerodynamic and mechanical design of high-speed turbomachinery, including centrifugal compressors, expansion turbines, rotordynamics, magnetic bearing integration, stress analysis, and machine architecture. The engineer will take designs from mean-line analysis and CFD through geometry release, build, test-stand validation, performance-map analysis, and iterative redesign. Work spans advanced cooling systems, novel working fluids, high-speed motor-driven machines, and rapid development from concept to production.

Own the electrical design and integration of high-power machines, including DC buses, inverters, motor drives, magnetic-bearing amplifiers, test-cell power systems, and load banks. Lead EMC, harmonics, bearing-current, insulation, arc-flash, and electrical-safety work through installation and commissioning. Develop safe work practices for energized equipment and bring first-of-a-kind systems to full-rating operation.
