About the role

Aplyr's Quick Take

This role is focused on designing and overseeing high and medium voltage power systems for large-scale battery energy storage projects. You'll be a key technical contact, ensuring safety, compliance, and efficiency while collaborating with various teams and external partners. It's primarily an individual contributor role with significant technical responsibilities.

Good fit

Ideal candidates have an engineering degree and substantial experience in power engineering, especially with utility-scale systems. Strong communication skills and a proactive approach to problem-solving will help you thrive here.

Worth noting

The position requires deep technical expertise in both battery technology and grid integration, which may limit the candidate pool. Familiarity with European regulations is also a specific requirement that could be a hurdle for some applicants.

Job Description

Responsibilities – What to Expect:

You will develop and specify HV/MV (High and Medium Voltage (utility-scale 1-100kV) power installations) substations and distribution systems for our BESS large-scale power plants and grid-scale projects.
You are responsible for primary and secondary technology, ensuring everything is safe and future-proof.
Standardization and reusability are important to you – you contribute sustainable solutions.
You provide technical support to our external suppliers and give final approvals.
As a key person between engineering, sales, and project execution, you ensure smooth processes.
You represent our projects as a technical contact for authorities, agencies, engineering firms, and service providers.
You develop concepts to optimize work processes and maintenance in low and medium voltage.
You ensure that all manuals and documentation are complete, understandable, and up to date.
