Head of Engineering

Your mission

Purpose of the role The Head of Engineering leads the Engineering department, the company's centre of technical know-how in design, commissioning and service. The core competency of our commissioning engineers and service technicians is battery energy storage: batteries and inverters, including the overarching control logic. The department operates as a shared resource pool: it provides qualified engineers and technical expertise to the Delivery department, where project managers are responsible for project delivery, and to the Service department, where the Service Manager is responsible for service delivery and meeting service level agreements (SLAs). The Head of Engineering is responsible for the competencies, capacity, quality of work and technical standards of these resources. Engineering is supported by the group Technology department, which develops the company's software (including the Podium EMS) and designs standardised BESS solutions; its hardware team holds group-level know-how in batteries and inverters. The Engineering department applies these standardised solutions in customer projects and feeds field experience back into their further development. You will work closely with the Managing Director, the Service Manager, the Head of Delivery, the Technology department and the Sales department to align engineering capacity and standards with the company's growth strategy.

Key responsibilities Leadership and people management

• Lead, coach and develop engineers in the Engineering department across all three areas of competency (design, commissioning, service); oversee recruitment, onboarding, performance management, competency development and succession planning.
• Build a culture of personal accountability and engagement, and act as the guardian of the company's technical know-how.

Resource management and allocation

• Plan department capacity against the combined demand of the project plan (Delivery) and service contracts (Service); allocate engineers to projects and service work in agreement with project managers and the Service Manager.
• Define and maintain clear rules of collaboration with the Delivery and Service departments: how resources are requested, prioritised and released, and who is responsible for what (Engineering = competencies, quality and capacity; Delivery/Service = execution, schedule and commercial outcomes).
• Resolve resource conflicts between projects and service, escalating trade-offs to the Managing Director where necessary; manage the department budget.

Design and electrical engineering

• Be accountable for the quality, standardisation and timeliness of electrical design documentation for BESS and EMS projects (single-line diagrams, protection and grid-connection design, LV/MV integration, as-built documentation).
• Ensure designs meet applicable standards, grid codes and safety legislation, and champion design-for-manufacture, design-for-installation and cost optimisation approaches.

Commissioning

• Own the commissioning methodology, checklists and safe working procedures used by engineers assigned to Delivery department projects; act as the main technical escalation point during commissioning and grid connection approval.

Supporting service competencies

• Provide qualified service engineers and technical expertise to the Service Manager, who is responsible for service delivery, SLAs and customer commitments; ensure engineers assigned to service work operate to agreed standards.
• Be accountable for root cause analysis (RCA) of technical failures in the field, and feed lessons learned back into design and commissioning practice.

Collaboration with the group Technology department

• Apply standardised BESS solutions designed by the Technology department in customer projects; ensure project-specific deviations are agreed with the Technology department and kept to a minimum.
• Channel structured field feedback (design, commissioning and service findings relating to batteries, inverters and EMS) back to the Technology department's hardware and software teams to improve the standard product.
• Coordinate training and knowledge transfer with the Technology department so that commissioning engineers and service technicians stay up to date on new product generations.

Cross-functional collaboration and continuous improvement

• Work with the Sales and Delivery departments on technical feasibility assessments, proposal reviews and realistic estimates of engineering work.
• Define and track engineering KPIs (design quality, first-time commissioning success rate, utilisation and availability of engineering resources) and continuously improve processes and tools.

Your profile

Requirements – Must Have

• University degree in electrical power engineering / electrical engineering (Ing./MSc. or equivalent).
• Demonstrable experience leading a design engineering department or comparable engineering unit (5+ years in engineering, 3+ years in a leadership/management role).
• Strong leadership and management skills: able to build, motivate and hold accountable engineers with diverse profiles (office-based design engineers, field commissioning engineers and service engineers).
• Ability to operate in a matrix structure: leading people whose day-to-day work is managed by project managers or the Service Manager, while retaining accountability for their development, quality and workload.
• Deep, hands-on technical knowledge in at least one of our core areas – ideally battery energy storage (batteries and inverters/power conversion), the core know-how of our commissioning and service engineers – or electrical design of LV/MV installations, grid connection and protection, industrial control/SCADA, or energy management systems (EMS).
• Knowledge of Czech/Slovak electrical engineering standards and safety legislation relevant to design and commissioning.
• Fluent Czech or Slovak and professional working English.

Requirements – Nice to Have

• Professional qualification in electrical engineering for independent activity/management under local regulations (e.g. Czech Decree 50/1978 Coll. §6–§8, resp. Government Regulation 194/2022 Coll., or the Slovak equivalent under Decree 508/2009 Z.z.).
• Experience with BESS, inverters, solar PV, EV charging or other renewable energy/energy flexibility technologies.
• Experience in a scale-up company environment: building processes and teams during project delivery.
• Chartered engineer (ČKAIT/SKSI authorisation) in electrical engineering.
