Job description

At Aquablu, we’re transforming drinking habits by replacing single-use plastics with innovative, sustainable hydration solutions. Are you ready to revolutionise the water industry with smarter, more innovative cooling systems? As our Mechanical Engineer, you’ll play a critical role in developing next-gen cooling, carbonation, and dispensing systems.

“That might sound really ambitious, but our team is part of an inspiring movement in an industry that’s thirsty for change.”

Marc, Co-founder of Aquablu

What You’ll Be Doing

  • Take ownership of designing and continuously improving cooling, carbonation, and dispensing systems, ensuring system reliability and efficiency.
  • Help us continuously evolve to a stable, scalable mechanical engineering framework.
  • Seamlessly incorporate thermal and cooling system designs into broader product development objectives.
  • Define initial parameters, oversee iterative testing, and refine prototypes for optimal performance.
  • Use in-field feedback and performance data to identify, research, and implement design improvements.
  • Work closely with the wider engineering team to develop factory tests, tackle multidisciplinary challenges, and share your expertise.
  • Apply a relevant level of project management, creating realistic timelines and delivering solutions that align with Aquablu’s mission.
  • The water industry is notoriously old-fashioned—we’re here to change that. Be bold, experimental, and ready to challenge the status quo.

About You

  • 3-5 years of hands-on experience in mechanical engineering, with a proven ability to innovate and troubleshoot in complex, multidisciplinary environments.
  • Solid, in-depth understanding of mechanical, fluid, and thermal systems, with practical experience in mechatronics and hydraulics.
  • Able to zoom out and create scalable, future-proof solutions that anticipate challenges we haven’t faced yet.
  • Skilled at prioritizing tasks and projects to ensure the team focuses on what matters most.
  • Comfortable with mCAD software and working directly on system designs and prototypes.
  • Fluent in English; Dutch is a bonus for local manufacturer collaborations.
  • Degree in mechanical engineering or similar degree with a strong theoretical background.

Nice-to-Haves:

  • Experience with HVAC or cooling system development.
  • Proficiency in simulation tools (e.g., CFD software) and testing methodologies.
  • Background in both start-ups and structured organizations, with expertise in setting up engineering workflows.
