Founded by the creators and core maintainers of vLLM, we sit at the intersection of models and hardware, a position that took years to build. ## About the Role We're looking for a Forward Deployed Engineer to make Inferact successful inside real customer environments. You'll work directly with customers to deploy, integrate, debug, and optimize vLLM-powered inference systems across cloud, Kubernetes, GPU, networking, and model-serving environments. This is a hands-on engineering role, not a traditional pre-sales position. You'll move from architecture discussions to implementation, own difficult production problems end-to-end, and work closely with core product and engineering teams to turn what you learn in the field into reusable product capabilities. Your work will directly affect customer time-to-value and how Inferact's platform evolves. ## Skills and Qualifications Minimum qualifications: - Bachelor's degree or equivalent experience in computer science, engineering, systems, machine learning, or similar. - Strong software engineering ability in Python, Go, TypeScript, or similar, with experience building production-quality integrations, tooling, services, automation, or prototypes. - Hands-on experience deploying or operating ML systems, model serving, AI infrastructure, cloud platforms, Kubernetes, or high-scale backend systems in production. - Ability to work directly with sophisticated customer engineering teams, understand ambiguous technical environments, and personally drive implementations and debugging to resolution. - Strong systems debugging skills across application, runtime, infrastructure, networking, identity, storage, observability, and distributed-system boundaries. - Ability to reason about latency, throughput, batching, model/runtime compatibility, scaling, reliability, and cost tradeoffs in production inference environments. - High ownership and strong technical communication, with the judgment to distinguish one-off customer work from problems that should become reusable product capabilities. Preferred qualifications: - Experience with vLLM, SGLang, TensorRT-LLM, TGI, Ray Serve, BentoML, or other LLM inference and model-serving systems. - Experience with NVIDIA or AMD GPUs, CUDA / ROCm, GPU scheduling, multi-GPU serving, or accelerator-backed infrastructure. - Experience deploying infrastructure software into enterprise, regulated, security-sensitive, or bring-your-own-cloud environments. - Experience building APIs, SDKs, CLIs, developer tooling, deployment platforms, control planes, or infrastructure products used by technical teams. - Experience profiling latency, throughput, concurrency, GPU utilization, bottlenecks, and performance regressions. Bonus points if you have: - Contributed to open-source ML systems, inference infrastructure, cloud infrastructure, Kubernetes, or developer tooling. - Worked in a forward-deployed, customer engineering, field engineering, or highly technical solutions role where you personally wrote and shipped code. - Built deployment playbooks, reference architectures, automation, or tooling that materially reduced customer time-to-production. - Resolved severe customer-facing production issues that crossed multiple technical layers and required close partnership with core engineering. - Turned repeated customer problems into reusable product features, abstractions, documentation, or platform improvements. Logistics - Location: This role is based in San Francisco, California. Will consider remote in the US for exceptional candidates. - Compensation: Depending on background, skills, and experience, the expected annual salary range for this position is $200,000 - $400,000 USD + equity. - Visa sponsorship: We sponsor visas on a case-by-case basis. - Benefits: Inferact offers generous health, dental, and vision benefits as well as 401(k) company match. ## About Inferact ## Company Overview - **One-liner**: Inferact is a startup founded by the creators of vLLM, the leading open-source LLM inference engine, dedicated to making AI inference cheaper and faster at global scale. - **Entity Type**: Private (Seed stage; raised $150M in seed funding) - **Headquarters**: San Francisco, California, United States (with a second office in Singapore) - **Founded**: 2025 - **Founders**: Simon Mo (CEO), Woosuk Kwon, Kaichao You (Chief Scientist), Roger Wang, Joseph Gonzalez, Ion Stoica ## Core Business - **Primary industry**: AI infrastructure / open-source inference engine for large language models - **Target customers**: AI labs, hyperscalers, startups, and enterprises deploying large-scale AI models (B2B, primarily technical teams) - **Mission**: Grow vLLM as the world’s AI inference engine and accelerate AI progress by making inference cheaper and faster. ## Products & Services - **vLLM (Open-Source Inference Engine)**: The core product – an open-source LLM inference engine that supports 500+ model architectures and runs on 200+ accelerator types. Inferact stewards and supercharges vLLM, with all optimizations flowing back to the community. - **Managed Inference Infrastructure (in development)**: Inferact is building infrastructure to absorb the complexity of deploying frontier models at scale, aiming to make it as simple as spinning up a serverless database. ## Market Standing - **Valuation/Market Cap**: Not disclosed (private company) - **Key Metric**: Total funding of $150M (seed round, announced 2026) - **Notable Investors/Partners**: Lightspeed Venture Partners (lead), Redpoint Ventures, Andreessen Horowitz, Altimeter Capital, Sequoia Capital, The House Fund, GC&H Investments, and others. Partnerships include NVIDIA, Red Hat, DigitalOcean, and Cohere. - **Growth Signals**: - $150M seed round – one of the largest seed rounds in AI infrastructure. - 22 employees with +27.3% monthly headcount growth. - vLLM ecosystem: 2,000+ contributors, 500+ model architectures, 200+ accelerator types. - Day-zero support for new model architectures (e.g., Cohere’s Command A+) and hardware integrations. - Active hiring with 5 open positions across inference, performance, kernel engineering, and cloud orchestration. ## Competitive Advantages - **Deep ecosystem moat**: vLLM is the de facto standard open-source inference engine, with a massive community and integrations across models and hardware that took years to build. - **Founding team credibility**: Creators and core maintainers of vLLM, with experience deploying at frontier scale (research and production). - **Hardware-software co-optimization**: Positioned at the intersection of model innovation and hardware diversity, enabling day-zero compatibility and performance optimizations. - **Open-source commitment**: All improvements flow back to vLLM, ensuring community trust and rapid adoption. ## Strategic Focus - **Current priorities**: Push vLLM performance further, deepen support for emerging model architectures (MoE, multimodal, agentic), expand hardware coverage (200+ accelerators), and build managed infrastructure to simplify deployment. - **Growth direction**: Close the capability gap between models and serving systems; absorb complexity so teams can focus on innovation rather than infrastructure. ## Why Work Here - **Culture**: High-caliber engineering team with roots in vLLM, PyTorch, and top AI labs. Emphasis on open-source contribution and cutting-edge inference research. - **Work policy**: Hybrid with a San Francisco HQ; at least one open role (Member of Technical Staff, Exceptional Generalist) is listed as Remote. - **Notable perks**: Opportunity to work at the frontier of AI inference, directly impact the open-source ecosystem, and collaborate with partners like NVIDIA, Red Hat, and major AI labs. - **Engineering culture**: Strong focus on systems engineering, kernel optimization, and cloud orchestration – ideal for engineers passionate about performance and infrastructure. ## Sources 1.
