Energy Engineer

You've built a solid foundation in HVAC engineering. Now you're ready to take it further.
At Hysopt, you'll combine your technical expertise with powerful simulation software to make HVAC systems smarter, more efficient and more sustainable. You'll work on real-world projects, collaborate with clients, and grow into a role where you're not just solving engineering challenges, but you're helping others solve them too.
With growing demand for our HVAC software, we're looking for an Energy Engineer with 3-5 years of hands-on HVAC experience to join our team.
WHAT YOU’LL BE DOING
First, you'll put your technical expertise to work:

• Assist our clients to optimise their HVAC installations and heat network projects, for both new construction and renovation projects.
• Analyse existing energy systems, identify inefficiencies, and develop smarter, more energy-efficient solutions.
• Get hands-on with the Hysopt software, supported by experienced colleagues who'll help you become an expert.
• Visit (international) client sites to understand installations first-hand and translate them into accurate simulation models.
• Model existing systems, evaluate different optimisation scenarios, and turn technical insights into actionable recommendations.
• As part of the Hysopt Expert Centre, be among the first to test new software features on real projects, before they roll out to our external user base.

As you grow into the role, so does your impact:

• Take ownership of projects from kick-off to presenting your results directly to the client, becoming the technical expert clients rely on.
• Become a client's day-to-day technical point of contact, helping them understand HVAC concepts, get the most out of Hysopt and apply your recommendations.
• Partner with our Customer Success team to help clients unlock the full value of our software.
• Share your expertise by delivering training sessions to new Hysopt users, online or on-site, once you're confident in the software and ready to share that expertise with others.
• Occasionally support pre-sales demos for prospective customers.

WHAT YOU BRING TO THE TABLE

• 3-5 years of hands-on experience in HVAC and/or heat network design, engineering, or consultancy.
• Master's degree in Engineering (Energy, Electromechanics, HVAC or similar), or equivalent through experience.
• Solid working knowledge of HVAC systems and heat networks and the ability to spot opportunities for better performance.
• A natural curiosity for technology and the motivation to master new software.
• Customer-focused mindset: you enjoy contact with clients and are comfortable being the technical face of a project, once you're up to speed.
• The ability to juggle multiple projects, set priorities and keep things moving.
• Strong communication skills, and the confidence to explain technical concepts clearly.
• Fluent in English, Dutch is a plus.

WHY HYSOPT?

• Make a measurable difference. Help reduce energy consumption, cut carbon emissions and improve the performance of HVAC systems in real buildings.
• Grow beyond traditional engineering. Build on your HVAC experience and develop into a well-rounded expert who combines technical engineering, project ownership and client interaction.
• Work at the forefront of innovation. Get hands-on with advanced simulation technology, contribute to real-world software development and keep learning from experienced colleagues.
• Join a team that knows its stuff (and enjoys what it does). Work alongside passionate, down-to-earth colleagues who love solving complex challenges together.
• Get rewarded for your expertise. Enjoy a competitive salary package, including a company car or mobility budget, health insurance and additional benefits.
• Enjoy flexibility. Combine time in the office and on-site with the option to work from home.
