Mechatronics Engineer
About Us
Wastewater Fuels Ltd is a UK-based clean technology company pioneering next-generation wastewater treatment and renewable energy systems. Founded in 2021 and headquartered in Coventry, West Midlands, we develop bio-electrochemical systems (BES) that convert wastewater into treated water and renewable fuels.
Driven by a mission to revolutionise wastewater treatment through low-energy, sustainable technologies, we aim to recover energy and protect natural resources. Our vision is to create a world where every drop of wastewater contributes to a circular, decarbonised economy — transforming what was once waste into a valuable source of clean energy and environmental resilience.
The Role
We are seeking a Mechatronics Engineer to join our growing engineering team, developing cost-effective and intelligent systems that transform how we control, monitor and optimise our bio-electrochemical systems.
This role involves mechanical design, electronics, and control systems, driving innovation in sustainable, automated technology. You will design, prototype, and implement smart electromechanical and control systems from lab-scale rigs to full-scale operational equipment working closely with process, electrical, and software engineers to deliver efficient, reliable, and data-driven systems.
Key Responsibilities
- Design and develop electromechanical and electronic systems, including sensors, actuators, and control components.
- Work with microcontrollers, Raspberry Pi, Arduino, and embedded systems to create custom automation solutions.
- Build and test IoT-enabled devices that integrate seamlessly with larger energy and treatment systems.
- Design and verify electronic circuits using lab tools (oscilloscopes, multimeters, etc.) and simulation software (e.g. LTspice).
- Develop and optimise automation and control algorithms for process efficiency and reliability.
- Collaborate on mechanical prototyping using 3D printing and rapid fabrication tools.
- Support installation, commissioning, and ongoing performance improvement of deployed systems.
- Maintain thorough technical documentation, schematics, and test reports.
- Contribute to the development of power and energy management systems for scalability.
- Ensure all designs meet safety standards and engineering best practices.
Desired Skills and Qualifications
- Degree in Mechatronics, Electrical, Mechanical, or Control Engineering (or a related field).
- Strong understanding of embedded systems, sensors, and control theory.
- Proficiency in CAD (SolidWorks, AutoCAD) and simulation tools (MATLAB/Simulink).
- Experience with PLC programming, Python, or C/C++ for automation and control.
- Familiarity with IoT technologies and system integration.
- A creative, hands-on, and experimental mindset, with strong problem-solving skills.
- Passion for sustainability, innovation, and clean technology.
