# Fall 2026 R&D Engineering Intern – Hydrogen Systems at Fourier

- **Company:** Fourier
- **Location:** HQ
- **Employment:** internship
- **Work type:** onsite
- **Posted:** 2026-08-06
- **Last confirmed live:** 2026-09-12
- **Apply:** https://jobs.ashbyhq.com/fourier/5b8d0c16-3b74-40ff-b5e6-9fdde6db0e86

## Job description

## About the role

This internship will involve supporting the design and validation of our commercial product. The intern will contribute to the design of a regenerative drying and purification system to enable efficient and continuous production of high-purity hydrogen. Working closely with an R&D engineer, the intern will characterize thermal/separation processes, develop control systems, and optimize operating parameters to satisfy key reliability and cost constraints. As the directly responsible individual overseeing an experimental test station, the intern will develop a data analysis framework to provide key insights into long-term physicochemical phenomena. The role may involve working with vendors to design and develop custom components.

## Requirements

- Currently pursuing or recently completed a B.S. or M.S. in Chemical / Materials / Mechanical / Environmental Engineering, Chemistry, Physics or similar
- Comfortable rolling up their sleeves to work with basic mechanical/electrical components, troubleshoot independently, and motivated to take ownership (agency) of hands-on lab work
- Strong fundamentals and problem-solving intuition in one or more of the following areas: thermodynamics, fluid mechanics, heat and mass transfer, reaction kinetics, phase equilibria
- Thrives in a fast-moving environment and can learn, iterate, and execute with velocity
- Must be available to start in August/September 2026 and work on-site in Mountain View, CA
- Highly organized with strong attention to detail and a commitment to following through (accountability)
- Clear, thoughtful communicator who works well on small, collaborative teams

## 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). Apply via [jobs.ashbyhq.com/fourier](https://jobs.ashbyhq.com/fourier).
