Your office is wherever our protection, control and automation systems are running.
Protection relay engineering is not learned from a book. It is learned at a substation, on a ship deck in the North Sea, in a laboratory in Belgrade, and on an offshore platform at sunset. We give you all four.
Nine environments. No two days are alike.
Our projects span the full range of power installations: from small hydropower plants in Bosnia, through offshore platforms in Brazil, to docks in Marseille, France. From scratch to commissioning, you are wherever the equipment is.
Offshore platforms & FPSO
Oil and gas platforms, FPSO vessels. Helicopter transfer; life experiences an office engineer will never have.
Ships & marine
Cargo, RoRo, passenger, naval. Paralleling 2 to 12 generators up to 5 MW while underway; real engineering under pressure.
Substations (LV, MV, HV)
Complete primary and secondary testing. Distribution, transmission, industrial networks. All major equipment brands.
Hydropower plants
Small hydropower plants (SHP) and large hydro facilities. Grid synchronisation, turbine control automation.
Solar & wind
Solar power plants with MV inverters and wind farms. Grid code compliance, LVRT/FRT protection, parallel grid operation.
BESS — battery storage
Battery Energy Storage Systems — fastest-growing segment. Converter protection, parallel operation with generators and grid.
Diesel & gas gensets
From single units to large diesel power plants. Multi-generator parallel operation, start/stop automation, PMS systems.
Industry & data centres
Velika industrijska postrojenja, biogas, oil & gas. Data centri sa N+1 i 2N redundansom napajanja.
Four weeks, four kinds of work.
Not every month is the same, but most follow this rhythm: a mix of deep concentration in the office, precise work in the lab, adrenaline in the field, and travel that shows you how the world actually generates electricity.
Design & preparation
You prepare protection parameter settings for a new 4 MW diesel generator in Hamburg. You draw the single-line diagram in EPLAN-u ili AutoCAD-u, verify the protection coordination calculation, write the test protocol for the FAT.
Secondary testing
SYMAP® units arrived from Hamburg, you configure them in the lab in Belgrade. Omicron CMC 356 injects currents, you monitor trip times. Functional ARC protection check.
On-site commissioning
Flight to Singapore. Three days before commissioning: wiring check, primary injection testing, grid paralleling, synchronising two generators. The client is watching. Everything must work first time.
Completion & handover
You write the commissioning report. You hand over SCADA integration to the client. You have already received the spec for the next BESS project in Berlin, IEC 61850 GOOSE communication. The cycle begins again.
We do not look for people who know everything. We look for people who want to learn everything; people who have no problem being on a ship deck on Friday after doing calculations in the office on Tuesday.
— from the internal HR guideHere you work with many different devices, not just one.
We make SYMAP®, but when you go on service work or replace an old system, on site you find equipment from various manufacturers — and you need to know how to commission all of it. You will work with all major communication protocols and with professional test equipment. That kind of experience is hard to gain elsewhere.
Microprocessor protection
A · 14 brandsSYMAP® is our product line; you work with the development team in Hamburg. Other brands are encountered on retrofit and service projects.
Communication & protocols
B · realtimeIEC 61850 is the industry-wide standard; here you work with it from day one, not after 5 years.
Test equipment
C · primary + secondaryOur laboratory has all of the above. You will learn to write automated test plans in Test Universe and RelaySimTest.
SCADA, RTU & PMS
D · system integrationPower Management Systems povezuju n generatora u inteligentnu celinu. Marine i offshore aplikacije; visoko cenjeno znanje.
Design (CAD)
E · schematics & documentationA protection relay engineer must read single-line diagrams faster than a typical electrical engineer. You will learn both; reading and drawing.
Project types
F · domainsDuring a career with us, the average engineer works across at least 4 different domains, which is why engineers gradually develop independence across different aspects of the work.
What you typically know after 3 years of work.
This is not a list of "nice to have" things, but a realistic snapshot of knowledge that most engineers acquire during their first 3 years of work — a foundation for a long career in the energy sector.

Five steps. A typical development path, around 8 years between entry and Site Manager level.
The pace of development depends on several factors — how fast you learn, how willing you are to travel, how much initiative you show, as well as company needs and position availability. These are typical steps for colleagues who have followed this path.
Engineer assistant
You learn the basics alongside senior colleagues. You assist on-site, learn to use Omicron, read single-line diagrams. You always travel with a more experienced colleague. Your job is to be a sponge for knowledge.
Junior engineer
You handle simpler projects independently in the lab. On-site you still shadow a senior engineer, but you have your own tasks. You learn one to two new protection brands per year.
Engineer
You lead your own mid-complexity commissioning projects. You travel independently. You learn additional brands (ABB, Siemens, Schneider). You mentor junior engineers.
Senior engineer
You lead commissioning of complete installations. You train junior colleagues. The client knows you by name and requests you first. Deep expertise in IEC 61850, PMS systems and parallel operation.
Management-level competencies
From this level, different paths typically open up depending on interests and company needs best:
A passport full of visas. Not a perk; it is the job.
Our engineers typically spend 60–80 days per year on site outside Serbia. Overseas flights are business class, accommodation is 4–5 stars. Travel is not a burden; it is a part of life that most office colleagues will never have.
