We’re on a mission to accelerate the energy transition with sustainable home energy for all and it’s our goal to help 3 million households transition by 2030. That is why we’re seeking a highly motivated and ambitious person that’s not afraid to make their hands dirty and make a real dent in the climate change challenge that we are already facing. Are you ready to rise to the challenge?

As a Mechanical Engineer, you won't just design products — you'll be crafting the future of home heating solutions. From heat pumps to cutting-edge cooling devices, you'll be at the forefront of developing a full ecosystem of sustainable energy solutions. If you're driven by the challenge of combating climate change and thrive in a hands-on, innovative environment, this role is for you.

🌱 What you'll be doing:

Mechanical engineering:

• Design and develop mechanical systems and components using CAD software, structuring models for simulation, analysis, and collaborative, multi-engineer workflows

• Translate conceptual designs into detailed, production-ready components, taking manufacturing methods (e.g. molding, machining, welding) and serviceability into account from the outset

• Apply Design for Manufacturing (DFM) and Design for Assembly (DFA) principles, and use GD&T on drawings and 3D models to ensure design intent is clearly communicated

• Investigate design and production issues using structured root cause analysis (e.g. 5 Whys, fishbone diagrams) and implement corrective and preventive actions

• Develop and execute test plans, and lead the prototyping, testing, and analysis of mechanical systems

• Support the manufacturing process by providing technical assistance and troubleshooting issues

Industrial design:

• Shape the aesthetics, form language, and ergonomics of components and products, balancing user-centered design with mechanical feasibility and cost

• Define and specify colors, materials, and finishes (CMF) that align with Quatt’s brand identity, durability requirements, and manufacturing constraints

• Build and evaluate appearance models and prototypes with users and stakeholders, incorporating feedback to refine form, usability, and perceived quality

Across both:

• Prepare clear engineering drawings, specifications, and documentation that support repeatability and knowledge transfer across the team

• Collaborate closely with senior engineers, designers, and installers, adapting your communication style to different audiences

• Conduct research to support engineering and design projects and stay up to date with industry trends

• Ensure all engineering and design activities comply with company standards, industry regulations, and safety guidelines

• Contribute to continuous improvement initiatives within the engineering team

💡 What you'll need?

• Bachelor’s or Master’s degree in Mechanical Engineering, Industrial Design Engineering, or a related field

• 3-5 years of relevant working experience, with demonstrated exposure to both mechanical design and industrial/product design

• Strong proficiency in CAD software such as Fusion 360, or similar tools

• A solid, working understanding of production processes — sheet metal design, plastic injection molding, and/or piping and couplings — and how to design for manufacturability, assembly, and service

• Working knowledge of structured problem-solving and root cause analysis methods, and an understanding of quality processes such as dimensional inspection and fit-and-finish requirements

• A good eye for aesthetics, form, and human-centered design, with hands-on experience in (or a strong affinity for) CMF selection and specification

• Comfortable sketching or visualizing concepts and building appearance prototypes to test with users.

• Strong collaboration and communication skills — comfortable working with senior engineers, designers, and installers

• Ability to produce clear, comprehensive technical documentation, including design specifications and test plans

• A problem-solving attitude and a hunger to learn

• Excellent written and verbal communication skills and fluent in English
