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 Corporate Controller to build and lead the accounting and financial operations that support Inferact's growth. You'll establish dependable books, a disciplined close, and reporting that leadership can trust, while translating customer agreements, infrastructure spending, and international operations into clear accounting policies and reliable workflows. This is a hands-on role for someone who can resolve a difficult accounting issue themselves and build the processes, systems, and team capacity around it. You'll oversee financial reporting, technical accounting, audit coordination, and the transaction processes behind payments, payroll, equity records, billing, collections, and cash controls. Working with engineering, GTM, Legal, People, external advisors, and the Strategic Finance Lead, you'll connect contracts and product usage to accurate invoices and revenue records, strengthen controls as complexity increases, and automate repetitive work without sacrificing review. The Strategic Finance Lead will lead planning and forecasting; you'll provide the accounting foundation and financial operations that make those plans credible. ## Skills and Qualifications Minimum qualifications: - Progressive accounting experience with meaningful ownership as a Controller, Assistant Controller, Head of Accounting, or equivalent leader in a growing company. - Strong US GAAP knowledge and practical technical-accounting judgment, including revenue recognition, stock-based compensation, accruals, and the accounting implications of commercial agreements. - Personal ownership of a complete close and financial statements, including reconciliations, journal-entry review, consolidation, and resolution of material accounting issues. - Hands-on experience across financial operations, including payables, receivables, billing, collections, payroll coordination, and cash-management controls. - Experience coordinating external audits and building documented policies, supporting schedules, review procedures, and effective internal controls. - Experience implementing or improving an accounting system and related workflows, with a track record of making financial data more reliable and reducing manual work. - Clear communication, sound judgment, and the ability to work independently with operational leaders, external accountants, legal advisors, and a small internal team. Preferred qualifications: - CPA or equivalent professional accounting qualification; public-accounting experience combined with hands-on operating experience is valuable. - Experience in AI infrastructure, cloud, developer tools, software, or another technology business with complex commercial terms or consumption-based billing. - Experience with international entities, intercompany accounting, foreign currency, and coordination with local accounting, payroll, or tax advisors. - Experience evaluating leases, fixed assets, infrastructure commitments, and other material arrangements relevant to a compute-intensive business. - Experience working with FP&A on management reporting, cost classification, and cash visibility while maintaining a clear distinction between accounting conclusions and forecast assumptions. Bonus points if you have: - Built a company's accounting function through a period of rapid growth rather than only administering an established process. - Connected contract terms and usage data to accurate invoicing, revenue accounting, and collections in a technical product business. - Led an ERP migration or financial-system integration without disrupting reporting, controls, or day-to-day operations. - Improved close quality, audit preparedness, or financial operations through automation while maintaining a clear review trail. Logistics - Location: This role is based in San Francisco, California and is on-site. - Compensation: The compensation package, including base salary and equity terms, is to be determined based on the final role scope, background, skills, and experience. - 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.
