Our breakthrough architecture enables highly modular and fully automated electrolyzers that scale to any size and optimize efficiency at all loads. We are on a mission to transition the global energy landscape towards a purely sustainable and emission-free future. ## About the Role We are seeking an experienced Process Engineer to support the successful and reliable design, integration, and deployment of our electrolyzer systems at customer sites. Fourier engineers work in a hands-on, collaborative environment to solve problems and push progress forward. Qualified candidates should have prior hands-on experience working in an industrial setting, ensuring customer success from design through commissioning. Roles and Responsibilities - Lead and optimize the process design of Fourier proprietary Electrolyzer Equipment stack ups and supporting systems. - Design and prototype tools to aid system deployment and commissioning. Plan, integrate, and ensure system compatibility and start up at customer sites. - Ensure that the Fourier Electrolyzer Equipment and processes meet and exceed customer and regulatory safety requirements and performance expectations. - Collect and analyze process field data in partnership with the Software & Controls and Engineering team to identify trends, intercept process issues and improve system performance. - Lead and rapidly troubleshoot engineering projects and resolve on-site issues with a high level of cross functional, problem-solving capability. - Coordinate and oversee third-party certifications (e.g., UL, TÜV SÜD) for hydrogen systems, including preparation of documentation, test plans, and engagement with certifying bodies. ## Qualifications Required - B.S. in Chemical Engineering or equivalent. - 10+ years of relevant experience in process engineering or system integration. - Hands-on work with gas and/or water piping, valve selection, and fluid handling systems. - Experience in the development and deployment of novel chemical or electrochemical systems. - Solid understanding of Process Safety Management requirements (PHA, HAZID, HAZOP). - Familiarity with industry standards and regulations (e.g., API, ASME, OSHA, EPA, NFPA). - Excellent communication skills and ability to execute under high-pressure situations. - Willingness to frequently travel to customer sites. - Experience with or willingness to manage product certification processes (UL, TÜV SÜD, or similar) for hydrogen equipment. ## What we offer - Fully paid Medical, Dental, and Vision coverage - Competitive salary and equity compensation commensurate with experience - 401k - Diverse and inclusive work environment - Paid sick days and vacation - Free lunches on-site ## About Fourier ## Company Overview - **One-liner**: Fourier develops on-site, on-demand hydrogen production systems using modular electrolyzers inspired by data-center architecture to make clean hydrogen affordable and accessible. - **Entity Type**: Private (Series A) - **Headquarters**: Palo Alto, California, United States - **Founded**: 2022 - **Founders**: Siva Yellamraju (Co-founder, CEO), Ali-Amir Aldan (Co-founder) ## Core Business - **Primary industry**: Renewable Energy Equipment Manufacturing / Clean Hydrogen Production - **Target customers**: B2B – pharmaceutical, petrochemical, ceramics manufacturers; heavy transportation; long-term renewable energy storage; industrial feedstock users. - **Mission**: Transition the global energy landscape towards a purely sustainable and emission-free future by making on-site hydrogen universally accessible. ## Products & Services - **Fourier On-Site Hydrogen System**: A modular, fully automated electrolyzer system that produces hydrogen on demand without transportation or storage. Each module contains roughly 20 small electrolyzers called “blades,” fed by a shared water pump and powered by repurposed data-center power supplies. Software manages each blade’s performance, optimizing efficiency and degradation – similar to a battery management system. ## Market Standing - **Valuation/Market Cap**: Not disclosed (private company) - **Key Metric**: Total funding of **$18.6 million** (Series A announced April 2025; seed round in 2023) - **Notable Investors/Partners**: General Catalyst, Paramark Ventures (co-leads Series A), Airbus Ventures, Borusan Ventures, GSBackers, MCJ Collective, Positive Ventures. - **Growth Signals**: - Headcount grew **76% YoY** to 34 employees (as of mid-2025). - Two lab-scale pilots completed with a pharmaceutical manufacturer and a solar energy company. - Two commercial-scale pilot plants underway (Ohio petrochemical plant; Fremont, CA airline parts manufacturer) expected operational by June 2025. - Operates in 5 countries (US, Canada, South Korea, Switzerland, India). ## Competitive Advantages - **Data-center-inspired design**: Uses off-the-shelf, commoditized power supplies and software intelligence to push complexity into a compute layer, dramatically lowering costs. - **Cost advantage**: Claims to deliver hydrogen at **$6–7/kg** versus the market’s $13–14/kg – a ~50% savings for customers without subsidies. - **No transportation/storage**: On-site generation eliminates hazardous logistics and extreme safety measures required for hydrogen distribution. - **Modular & scalable**: System is sized like two server racks; can scale from lab to industrial throughput (targeting 6–20 kg/hour, 300 kW–1 MW capacity). ## Strategic Focus - Scale commercial pilots and move toward broader deployment. - Optimize efficiency through data-driven blade management (treating production as a data optimization problem). - Target industrial customers with high hydrogen demand (pharma, petrochemical, ceramics, aerospace). - Expand into heavy transportation and long-term renewable energy storage use cases. ## Why Work Here - **Culture**: “Engineering Audacity” – the company seeks bold engineers, innovators, and problem-solvers to tackle the world’s toughest energy challenges. - **Work environment**: On-site in Palo Alto, CA (physical office). Small, fast-moving team (~34 people) with a flat, high-impact structure. - **Leadership & team**: Co-founders with deep technical backgrounds; team includes alumni from Apple, Sila Nanotechnologies, Tesla, and other top engineering organizations. - **Growth opportunity**: Early-stage company with strong investor backing, 76% headcount growth, and active hiring across mechanical, electrical, software, and manufacturing roles. - **Active job postings**: 7 open roles as of mid-2025 (e.g., Sr. Mechanical Engineer, Engineering Program Manager, Director Electrical Engineering, Process Engineer).
