Top Tech Jobs & Startup Jobs in Austin, TX

Lead development of a compiler toolchain for a custom LLM accelerator: design IR/graph transformations and lowering passes, optimize compute and memory patterns, integrate with PyTorch/JAX/Triton, build test infrastructure, and ensure correctness and performance for hybrid optical-electronic hardware.

Develop hardware-aware post-training quantization and model adaptation methods for LLMs, diffusion models, and other machine learning applications targeting optical inference hardware. The role involves numerical and constrained optimization, controlled experiments, research-quality implementations, model deployment across PyTorch, Triton, and JAX, GEMM optimization, and collaboration with hardware and software teams to co-optimize AI architectures. The engineer will also publish research while protecting company intellectual property.

Lead the architecture, design, simulation, validation, and commercialization of silicon photonic devices (grating couplers, waveguides, SOAs, photodetectors). Develop link budgets, collaborate with foundries using PDKs, perform DFM/DFT, run optical simulations, characterize devices in lab, integrate with electro-mechanical and software teams, lead design reviews, support IP and patent filings, and mentor junior engineers.

Lead full-cycle technical recruiting for hardware, semiconductor, and photonics roles. Source senior and junior candidates, manage interview processes and scheduling, partner with Talent to build hiring workflows, and represent technical credibility to candidates and hiring managers.

Lead Security Engineer to design and defend cloud, network, and systems infrastructure. Implement zero-trust, IAM/PAM, SIEM/EDR, vulnerability management, incident response, vendor/customer security assessments, and drive SOC 2 Type II compliance while partnering with engineering and legal.

Develop low-level firmware for a hybrid optical-electronic LLM accelerator: implement board/system management, hardware interfaces, debugging/profiling tools, validate performance, collaborate on software-hardware integration, and support customer integration.

Lead end-to-end datacenter scale-out networking architecture for the T100 platform: host networking stack to EIC PCIe bridge, NIC integration, and DMA into HBM. Define RDMA/transport/offload (RoCEv2, UET), PCIe P2P/ACS policies, queue/completion semantics, vendor selection, collective communication modeling, DPU roadmap, standards representation, and mentor architecture and software engineers.

Lead and build Neurophos' in-house IT function across Sunnyvale and Austin. Own on-prem Linux compute for EDA/CAD, storage, backup, SSO/IdP (Okta), GitHub Enterprise, cloud (Azure) administration, network design, MSP governance, endpoint fleet management, and insourcing roadmap. Design hybrid connectivity, security/compliance evidence, and scale infrastructure from ~50 to 150+ employees while hiring and mentoring the IT team.

Perform die- and wafer-level optical characterization of metasurface photonic devices. Execute spectral and electro-optic measurements, automate instrument control and data acquisition with Python, analyze large datasets to assess yield and device performance, document campaigns, and improve test setups and measurement throughput.

Lead development of inference servers and racks, owning electrical, mechanical, and systems engineering from boards and interconnects through rack-level power and high-speed channel closure. Build and lead the Systems team, drive integration/bring-up, EVT/DVT/PVT sign-off, system reliability (RAS), and manage schedule and budget for full-scale product delivery.
