Your team Based at the headquarters in Saint-Ouen, our Data Centers Department brings together about ten professionals with complementary expertise: MEP engineers, project managers, and project directors. We manage operations of all sizes, both in new construction and renovation, at the heart of a demanding and constantly evolving technical environment. In this context, you will very regularly be required to communicate in English: a good oral and written level is required. As an HTB Engineer, your missions will be as follows: During the Design phase (APS → PRO → DCE) Definition of HTB / HTA electrical architectures: HTB substations (AIS / GIS) network connection diagrams (RTE) redundancy and distribution diagrams
Execution of electrical studies: power balance short-circuit calculations selectivity and protection coordination earthing systems
Sizing of installations: HTB/HTA transformers HT cells protection / control-command systems
Drafting of technical documents: calculation notes, CCTP, diagrams Network connection & RTE environment Management of connection studies: relations with RTE definition of substation network / client site interfaces
Contribution to files: feasibility studies connection agreements phasing and commissioning
Integration of network operation constraints Implementation monitoring: VISA of execution documents Monitoring of HTB / HTA works (substations, links, transformation) Organization and monitoring of tests: FAT / SAT dielectric tests energization
Participation in commissioning Electrical safety studies – Arc flash (SCAAF) Execution of arc flash studies: incident energy calculations determination of safety distances
Analysis of fault scenarios Recommendations on: protection settings network architecture
Determination of necessary PPE Integration of results into the design Expertise & support HTB technical referent on projects Assistance to MOE / AMO teams Participation in technical choices and arbitration Supervision of engineers / designers
The position requires mastery of requirements specific to critical infrastructures (data centers): Continuity of service: redundant architectures (N, N+1, 2N) absence of single point of failure fault tolerance and maintenance capacity Complex interfaces HTB / HTA / BT interaction coupling with: gensets, UPS, BESS fine sequencing of energization Internal projects show these extended energy interfaces (HTB substation, GE, BESS, energy modules) Reinforced commissioning: multi-level tests (L1 to L5), verification of backup scenarios, validation of final availability Operational constraints: maintainability and operability, management of network transfers, strict safety procedures High client requirements: high schedule pressure, energy performance, contractual requirements (SLA, availability)
Your assets Training: Engineering degree in electrical engineering / electrotechnics or equivalent Experience: MOE / engineering experience Proven experience on HTB projects Intervention at 225 kV and ideally 400 kV levels Experience in: HTB substations RTE connections
Data center projects or critical infrastructures Technical English required (international projects) Expected qualities: Technical rigor Ability to analyze complex systems Autonomy and technical leadership Client relations You never work alone; a good team spirit, the ability to take a step back in your missions, great curiosity, and a sense of sharing and mutual aid with your colleagues will be your assets for success.
