The Role
Design, program, and maintain PLC-based control systems for lab and industrial electrolyzer units. Install, wire, and troubleshoot sensors, actuators, and electrical panels. Integrate HMI graphics with control logic, retrofit legacy systems, and collaborate with software engineers. Support deployment standardization and occasional interfacing with existing C-based code.

About Dioxycle
Dioxycle is pioneering breakthrough carbon utilization technologies that convert industrial emissions into sustainable chemicals with unprecedented energy and cost efficiency. By displacing fossil fuels for the production of key chemicals, Dioxycle has the potential to ultimately reduce over 800 million tons of CO2 per year, representing over 2% of the world's emissions.
At the core of our process is a novel "carbon electrolyzer", a machine capable of using just electricity and water to convert carbon emissions back into valuable everyday essential chemicals. Our team is innovating across chemical, mechanical and system engineering to turn carbon transformation into an economically feasible, industrial reality through this completely novel technological approach. Having completed our industrial-scale electrolyzer prototype, we are now working with our chemical and downstream offtakers towards First-of-a-kind plant deployment and subsequent commercial roll-out.
We are supported by world-class funders including Bill-Gates-founded Breakthrough Energy Ventures, Lowercarbon Capital and Gigascale Capital and have raised $40M to date. We operate from two centers in Paris and California (so whether you are passionate about outdoors or good food/art scenes, we have a location for you to join!)
Your Mission
Dioxycle is seeking a hands-on Automation & Electrical Engineer to join our hardware team. You'll be working directly on the control systems that operate our electrolyzer stacks - programming PLCs, maintaining wiring and instrumentation, and helping us build a scalable deployment architecture as we grow from 40 systems to many more.
This is a role for someone who loves being close to the hardware, is comfortable picking up new tools quickly, and wants to see the direct impact of their work on real physical systems. You'll have real ownership over a critical part of our systems, at a moment when the team and the fleet are both growing fast. The problems are hard, the impact is direct, and the work is never boring.
Your key responsibilities will center around:
- Program and maintain PLC-based control systems (Beckhoff) on our lab and field electrolyzer units. This covers lab-scale test units of small and medium size but also includes onsite industrial-scale pilots (that are so big you need to lift them with a crane)
- Wire, install, and troubleshoot sensors, actuators, and electrical panels
- Work with our team to configure new systems and contribute to how we standardize deployments going forward
- Collaborate with Dioxycle's software engineers to integrate HMI graphics with control logic
- Participate in the retrofitting of legacy systems with new-generation PLCs
- Occasionally interface with existing C-based code on older systems
We're open to a few different profiles - what matters is curiosity, hands-on instinct, and a real interest in automation work. Experience with PLCs is a huge plus.
Abilities and expertise we are looking for
- Diploma (e.g. DUT) or degree in electrical engineering, automation, or a related field - or equivalent hands-on experience
- 3+ years of experience (internships/apprenticeships and personal projects all count, however, candidates with more experience are warmly encouraged to apply)
- Some exposure to PLC programming (Beckhoff, Rockwell, Siemens, or Schneider - any is fine; you'll learn Beckhoff on the job)
- Comfort with at least one programming language (e.g. Structured Text, Python, C)
- Understanding of version control (Git) for collaborative code work
- Familiarity with electrical panel design and reading wiring diagrams
- Hands-on experience with sensors, actuators, and basic electronics troubleshooting
- Comfortable using an oscilloscope and basic electronics measurement tools
Bonus: experience with eCAD tools, and/or a background in industrial settings like packaging, robotics, or process control.
Mindset we are looking for
- Exemplary work ethic and self-driven attitude: you get things done fast and to a high standard and you don't drop the ball
- "Street-smart": you don't take no for an answer and will figure out a way to solve anything with the means available
- Commitment to the mission and ambition and to creating a kind, high-performance and fun atmosphere at work (100% on-site role)
- Passion for innovation and problem-solving attitude
- Dedication to investing time and effort for the betterment of the team
- Going the extra 20% that makes a good deliverable into an outstanding deliverable
- Humble, low-ego and curious
What we have to offer
- Unique journey: We are an early-stage company with a world-class team and a flat structure.
- Impact: We are building a product that will reshape century-old industrial processes to build a better, more sustainable and resilient world
- People-first: We love our people. We are excited to see one another every morning when coming to work. We choose people and they choose us to share a similar excitement.
- Feedback over ego: We are self-improving whilst helping others grow. We are no-ego doers and we are all responsible for shaping the company.
- International team: We are an international team made up of over 17 nationalities, and hopefully many more soon!
- Fun: We constantly strive to cultivate a great work atmosphere and organize regular team events.
- Competitive compensation packages
- Generous Employee Stock Ownership plans
- Health Insurance: Medical, dental, and vision coverage.
- Ergonomic work stations & state-of-the-art equipment
Our process
- An initial video call with Grace, Director of People, to discuss Dioxycle's mission, get to know you, understand your career expectations, and answer your questions (30 mins)
- Expert screening call with Peter, Head of Systems (30 mins)
- Technical deepdive interview/case study with Peter, Head of Systems (1 hour)
- Onsite interview including Cofounder interview & opportunity to tour our technology & meet the wider team (2-3 hours)
- A series of reference calls with provided contacts
Skills Required
- Diploma or degree in electrical engineering, automation, or related field, or equivalent hands-on experience
- 3+ years of relevant experience (including internships, apprenticeships, personal projects)
- Exposure to PLC programming (Beckhoff, Rockwell, Siemens, or Schneider)
- Comfort with at least one programming language (Structured Text, Python, or C)
- Understanding of version control (Git)
- Familiarity with electrical panel design and reading wiring diagrams
