Senior Mechanical Engineer Opportunity at Aquablu

Job Description

🌊Who are we?

At Aquablu we’re disrupting the marketplace with a revolutionary (flavored) water system. Brought to life in 2018, our founders Marnix and Marc promised a healthy but tasty alternative to soft drinks. Today, our water is tapped in almost 16 countries. And we continue to make waves by teaming up with industry leaders like Heineken, Adyen and Marriott Hotels. Join us in our mission to save one billion plastic bottles by 2030!

“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

Are you ready to revolutionise the water industry with smarter, more innovative cooling systems? At Aquablu, we’re on a mission to redefine sustainability with cutting-edge solutions. As our Senior Mechanical Engineer, you’ll play a critical role in developing next-gen cooling, carbonation, and dispensing systems while helping professionalize and future-proof our mechanical engineering expertise.

By joining Aquablu, you’ll empower the tech team to not only meet current demands but also plan for long-term growth. Your work will directly support the development of smarter, more efficient systems while setting the foundation for a structured, scalable mechanical engineering team.

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. Offer guidance on creating structure, defining workflows, and setting team priorities.
• 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 and guide our mechanical engineer and 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

• 6+ 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.
