Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The candidate must hold National Grid Settings Authorisation certification. Industrial experience in AC substation design and primary plant, with an understanding of protection, control/SCADA, OT cybersecurity, telecom, metering, CT/VT specifications, and substation integration, is highly desirable.
Roles and Responsibilities
- Prepare high voltage protection settings calculations e.g. low impedance feeder differential and distance protections, transformer biased differential protections, and low impedance busbar protection calculations or high impedance busbar protection circulating current calculations.
- Perform short-circuit fault level calculations manually to IEC60909 standard for symmetrical and unsymmetrical faults using sequence components
- Use power system analysis software (e.g., DIgSILENT PowerFactory) for fault level studies and protection grading/selectivity reports.
- Conduct arc-flash analysis using tools such as Alpi Caneco BT for LVAC 400V systems.
- Prepare first-time energisation circuit switching programs and automatic reclosure switching sequence reports
- Technical analysis of employer’s requirements to define and optimise protection functionality selection
- Provide advisory support to project and tendering teams on protection related matters
- Apply judgment to propose different solutions outside set parameters with guidance.
- Collaborate across internal teams to achieve results
- Actively participate in business improvement initiatives within the engineering department
- Offer support and mentorship to junior engineers in enhancing their professional engineering competencies.
