Technical Building Equipment Engineer (Electrical)

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 TGA Engineer (Electrical) to join our team, focused on designing electrical systems for residential, hybrid, and energy-efficient buildings across HOAI phases 1–5, with potential involvement up to HOAI 7. This role will support compliant, coordinated, and buildable electrical solutions for modern timber-based construction.

• Designing electrical systems across HOAI phases 1–5, with potential involvement in HOAI 6–7;
• Preparing technical documentation, drawings, and specifications for residential and commercial building projects;
• Supporting tender documentation and specifications;
• Coordinating electrical design with architecture, structural engineering, and other disciplines;
• Supporting grid connection approvals and communication with network operators;
• Designing and coordinating systems for PV installations, e-mobility charging, and energy-efficient buildings;
• Working with contractors during design development and construction coordination;
• Supporting site supervision and author’s supervision where required.

• Strong experience in electrical building services design for residential or hybrid buildings;
• Degree in Electrical Engineering, Building Services Engineering (TGA), Energy Engineering, or a related field;
• Knowledge of HOAI design phases, especially LPH 1–5;
• Solid understanding of DIN VDE standards, TAB requirements, and grid connection processes;
• Experience with PV systems, e-mobility charging infrastructure, and KfW or energy-efficient buildings;
• Proficiency in Revit and AutoCAD;
• Experience with EPLAN or WSCAD;
• Experience with DIALux or similar software for lighting calculations; 
• Experience with Caneco or SIMARIS;
• Knowledge of electrical requirements for timber construction is a strong plus; 
• Experience with AVA Software (e.g. Orca AVA) is an advantage; 
• Ability to coordinate with contractors, architects, structural engineers, network operators, and other technical teams;
• 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;
