Technical Building Equipment (TGA) Engineer

All3 is transforming how buildings are conceived, developed, and delivered. We combine AI-powered design with robotic prefabrication and on-site assembly to build custom architecture at the cost and speed of mass production — unlocking even the most complex sites.

We’re currently seeking a Technical Building Equipment (TGA) Engineer to join our team, focused on leading technical building systems development as sales opportunities progress from proposal to contract, ensuring compliant, energy-efficient TGA designs for timber and hybrid construction projects.

• Developing TGA concepts and system designs as projects progress from proposal phase toward contract coordination;
• Coordinating mechanical, electrical, and plumbing systems within timber and timber-hybrid building solutions;
• Preparing and reviewing documentation required across German planning and permitting stages;
• Ensuring system designs align with KfW40, DGNB, LEED, and QNG+ requirements;
• Collaborating with architecture, structural engineering, sustainability, and product teams to integrate TGA needs early in the design process;
• Evaluating feasibility, performance, and cost impacts of TGA solutions to support project development decisions;
• Using Revit, RFEM, and Autodesk tools to model and validate system layouts;
• Supporting clients, partners, and internal teams with clear technical communication in both German and English;
• Driving continuous improvement of energy-efficient and sustainable building system strategies for All3’s platform.
   

• Professional experience in designing modern, energy-efficient TGA systems, ideally within timber or timber-hybrid buildings;
• Degree in Building Services Engineering, Mechanical Engineering, or a related field.
• Strong knowledge of KfW40, DGNB, LEED, and QNG+ requirements and documentation;
• Proficiency in Revit, RFEM, and Autodesk design tools;
• Understanding of German planning phases (HOAI) and the documents required at each design stage;
• Familiarity with sustainability certifications, energy performance standards, and lifecycle considerations;
• Ability to work in both German and English in technical and collaborative settings.

• Chance to be a part of a large-scale project;
• Team driven by impactful cause;
• Remote format of work;
• Flexible working schedule;
• 28 days of annual leave.
