Workplace: hybrid

Department: R&D

Description

Ever wondered how complex engineering challenges become powerful software features?

At Hysopt, we develop simulation software that helps engineers design, analyse and optimise HVAC systems. We're looking for a Functional Analyst who enjoys understanding how things work, solving complex problems and turning technical needs into practical software solutions.

You'll join our R&D team, working closely with HVAC experts, software developers and users to help shape and improve our software. Whether your background is in functional analysis or HVAC engineering, what matters most is your analytical mindset, technical curiosity and eagerness to learn.

WHAT YOU’LL BE DOING

• Turn complex needs into clear solutions. Work with HVAC engineers and software users to understand their challenges and translate them into functional requirements.
• Bridge engineering and development. Collaborate with software developers to design functionalities that are technically sound, intuitive and valuable to users.
• Put new features to the test. Validate software functionalities, investigate unexpected behaviour and make sure the results match both technical requirements and user expectations.
• Solve problems at their core. Analyse software issues, identify root causes and work with the development team to find effective solutions.
• Help our software evolve. Contribute ideas for improvements, support feature documentation and help ensure new developments deliver real value.

WHAT YOU BRING TO THE TABLE

• You have a background in HVAC engineering, functional analysis or a related technical field. Experience in both is a big plus, but not a requirement.
• You have strong analytical skills and enjoy breaking down complex problems into clear, workable solutions.
• You're curious about how software works and interested in the technical principles behind heating and cooling systems.
• You communicate clearly and enjoy collaborating with engineers, developers and other stakeholders.
• You're proactive, detail-oriented and take ownership of your work.
• You're fluent in English. Dutch is a plus.

WHY HYSOPT?

• Challenging technical work. Dive into complex engineering problems and help turn them into innovative software solutions.
• The best of both worlds. Combine HVAC engineering with software development and build expertise at the intersection of both.
• A real say in product development. Work closely with our R&D team and see your contributions make it into the software.
• Keep learning. Develop your skills alongside experienced engineers and developers in an environment that values curiosity and initiative.
• A great team and attractive package. Enjoy supportive colleagues, a competitive salary, company car or mobility budget, health insurance and flexible working arrangements.

Ready to shape what's next?

If you enjoy solving complex problems and want to help build technology that makes HVAC systems smarter and more efficient, we'd love to meet you.

Don't tick every box? Apply anyway. If you bring the right mindset and a strong foundation in either HVAC or functional analysis, we'd still love to hear from you.
