Top Tech Jobs & Startup Jobs in NYC, NY

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.

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.

Build software systems for large-scale AI compute operations, including fleet health monitoring, automated repair and RMA workflows, hardware qualification, facility asset management, and structured operational procedures. Develop production features using Go, Python, or TypeScript; integrate LLMs and agentic tools; support on-call operations; and work closely with production engineers and facility operators to improve reliability and deployment speed.

Lead product direction for ontology and data products that model and support compute production. Translate messy operational domains into data models, specs, and product surfaces; drive technical tradeoffs and ship end-to-end; run stakeholder discovery and validate impact; define and track success metrics to optimize product outcomes.

Counsel will lead the structuring, drafting, and negotiation of complex commercial agreements supporting data center development, including supply chain, manufacturing, procurement, and technology transactions. The role manages sophisticated negotiations, oversees outside counsel, coordinates transactions across internal teams, and advises business leaders on legal and commercial risks. Candidates must hold an active law license and demonstrate strong judgment, communication, and experience handling high-stakes agreements.

Build and maintain foundational infrastructure platforms (CMDB, DCIM, asset lifecycle, monitoring, observability, automation). Deliver self-service tooling, workflow orchestration, integrations, and scalable, reliable systems while partnering with operations, security, and product teams. Drive technical direction, CI/CD, IaC, and production readiness for fleet-scale data center infrastructure.

Architect the solid-state transformer platform for gigawatt-scale AI data centers. Select converter topologies and semiconductor strategies, lead power electronics, magnetics, and controls engineers through hardware development, define MVDC system interfaces, create prototype roadmaps, evaluate build-versus-partner options, and develop vendor, laboratory, and university partnerships. Own technical trade-offs involving efficiency, redundancy, manufacturability, device availability, and MW-scale system integration.

Own hardware new product introduction programs from kickoff through rate production for racks, gear, or power conversion products. Manage schedules, stage gates, risks, dependencies, design changes, long-lead components, readiness reviews, and cross-functional decisions across engineering, manufacturing, quality, supply chain, and delivery. The role requires technical judgment, disciplined escalation, and the ability to make difficult scope, schedule, and recovery decisions under significant schedule pressure.
