Role Summary Provide hands-on after-sales support for RelyEZ BESS projects in Poland. During the initial period (approximately three months), focus on the Puławy project, supporting rapid attendance for critical faults, initial diagnostics and safe on-site action as part of a scheduled response team. Once the local support arrangements are established, transition to routine field service, maintenance, spares coordination and customer support, with occasional travel to other projects as needed.
1. Key Responsibilities
On-site response: Initially support the Puławy site on an agreed on-call rota, helping the local service team meet the P1 attendance target of within 2 hours by day and 4 hours at night. Assess safety first, carry out authorised isolation and initial diagnostics, and coordinate follow-up repairs. Attendance does not mean completion of repairs. Routine service arrangements apply after the initial support phase.
Inspections and preventive maintenance: Work with the local O&M provider on scheduled inspections within the role’s authorised scope, covering battery containers, thermal management, fire safety and PCS / EMS / BMS operating status; maintain clear inspection records.
Troubleshooting: Investigate alarms, retrieve logs, perform electrical checks and support fault isolation with HQ and OEM specialists. Carry out basic repairs only when qualified and authorised, support safe restoration and provide site evidence for major-incident root cause investigations.
Warranty and spares: Collect fault logs, photos and other evidence for HQ warranty assessment; support spare-parts requests, stock checks, tools and test equipment readiness.
Local service coordination: Liaise with O&M partners and specialist contractors, verify attendance and work records, and report quality or capability gaps. Commercial and contractual supplier management remains with the responsible manager.
Customer communication and reporting: Act as a local technical contact, maintain service tickets and response records, and draft incident and inspection reports for HQ review.
2. Experience
Technical diploma, vocational qualification or equivalent hands-on experience in Electrical Engineering, Automation, Mechatronics or a related field; a university degree is an advantage, not a requirement.
At least 2 years of practical field service, maintenance, commissioning or troubleshooting experience with electrical equipment. Experience with PV inverters, UPS, industrial electrical systems, converters or BESS is welcome.
Customer-facing technical and troubleshooting experience; emergency response, European power-sector or BESS experience is a plus.
A valid category B driving licence recognised in Poland, with willingness to travel within Poland and occasionally to neighbouring countries.
3. Competencies
Customer focus: take ownership of safe on-site support, service records and issue follow-up; respond promptly to assigned emergency call-outs during the initial Puławy support rota.
Composure on site: safety first, diagnosis second; no live working under risk.
Practical judgement and teamwork: carry out initial checks independently and involve appropriately qualified personnel whenever work is outside your authorisation.
Communication and record-keeping: fluent Polish with customers and local bodies, working English with HQ; complete and traceable incident timelines and action records.
4. Technical Skills
Strong electrical fundamentals and ability to read single-line diagrams and basic communication diagrams. Familiarity with batteries, BMS, PCS, EMS, fire safety or thermal management is an advantage; BESS product training will be provided.
Relevant Polish electrical qualifications (e.g. SEP G1 E) are preferred; G1 D is an advantage. Any regulated electrical work must be performed only with the required qualifications and company authorisation.
Able to use standard electrical test instruments for basic diagnostics, learn to retrieve EMS / BMS logs, and follow technical instructions in Polish or English.
5. Working Conditions
Initial project response: During the early Puławy support phase, join the scheduled local response team helping to meet the P1 site-attendance target of 2 hours by day and 4 hours at night. This is a team coverage arrangement, not a permanent individual 24/7 on-call requirement.
Base location: Initially based near Puławy or Lublin for timely attendance during assigned shifts. Location may be adjusted later, including Warsaw, once appropriate local response coverage is in place.
Standby: An initial intensive response period of approximately three months, with a planned on-call rota and backup support from the wider service network. Routine field-service arrangements follow once the initial phase is completed, subject to applicable Polish working-time and rest requirements.
The company provides a vehicle or mileage allowance, test instruments, PPE and local spares.
6. Reporting & Interfaces
Administrative and daily assignment: Regional Service Manager. Technical conclusions and service records: HQ Technical Department.
Incident and inspection reports are drafted by this role and reviewed by HQ before submission to the customer.
