ESA Technical Engineering Graduate Job Description

Job Purpose

The Graduate Energy Analyst/Engineer will support ENGIE South Africa’s Renewable Generation Business Unit through technical modelling, engineering analysis, and optimisation of renewable and hybrid energy projects.

The role will provide exposure across the full project lifecycle, including origination, pre-development, development, financial close, construction, operations, and asset management.

The graduate will work closely with internal technical, development, grid, procurement, finance, project execution, operations, and asset management teams, as well as external consultants, OEMs, contractors, and partners.

The role will focus on solar PV, wind, battery energy storage systems, hybrid plant optimisation, dispatch strategies, curtailment, grid export, project performance, and related technical documentation.

The programme will include local and international learning, training, and knowledge-sharing opportunities within ENGIE Group.

What you will do

• Support the screening of renewable and hybrid project opportunities, including site, grid, resource, market, and commercial inputs.
• Assist with preliminary PV, wind, BESS, inverter, transformer, grid export, and hybrid configuration sizing during feasibility, development, and tender stages.
• Prepare early yield, dispatch, curtailment, clipping, energy shifting, revenue sensitivity, LCOE, LCOS, capacity factor, equivalent cycle, round-trip efficiency, degradation, and availability assessments.
• Develop and maintain Excel- and Python-based models for hybrid sizing, BESS dispatch, state of charge, grid export, curtailment, and performance analysis.
• Support engineering inputs for layouts, single-line diagrams, BESS configurations, AC/DC coupling assumptions, metering points, grid connection limits, and project performance assumptions.
• Review consultant, OEM, EPC, BOP, O&M, Owner’s Engineer, Independent Engineer, LTA, and LTSA inputs, and summarise key modelling assumptions, technical risks, recommendations, and mitigation actions.
• Draft, contribute to, and support negotiations on owner specifications, technical schedules, tender returnables, and technical inputs to EPC, PPA, FSA, OMA, LTSA, Owner’s Engineer, Independent Engineer, and related agreements.
• Support bid models, lender due diligence, investment decision materials, and financial close readiness for renewable and hybrid PV+BESS projects.
• Assist with the technical evaluation of performance guarantees, dispatch assumptions, degradation, availability, grid export, curtailment, statutory, safety, and quality requirements.
• Support the review of construction-stage drawings, design updates, single-line diagrams, equipment data sheets, contractor submissions, design changes, commissioning milestones, and performance testing inputs.
• Assist with tracking grid connection actions, BESS integration risks, handover requirements, and verification of modelling assumptions against final design, commissioning data, and operational performance.
• Support operations and asset management analysis, including PV/wind generation, BESS charge and discharge, state of charge, curtailment, clipping, degradation, cycling, outages, warranty issues, optimisation opportunities, and model-versus-actual reviews.
• Prepare concise technical summaries, structured engineering documentation, version-controlled working files, risk inputs, project handover materials, and ad hoc advisory support for operational assets and construction projects.
• Conduct technology watch activities, incorporate ENGIE Group experience and standards, and share knowledge within the Technical Oversight and Support team.

Qualifications, Skills and Candidate Profile

• Bachelor’s or master’s degree in Electrical Engineering, Energy Engineering, Mechanical Engineering, Computer Science, Data Science, Applied Mathematics, or a related technical field.
• Graduate or early-career candidate with a strong interest in renewable energy technologies, including solar PV, wind, BESS, hybrid systems, grid integration, energy modelling, optimisation, and data analytics.
• Strong Excel capability is required; interest or exposure to Python, MATLAB, Power BI, HOMER, PLEXOS, PVsyst, PVDesign, or similar modelling and analytics tools would be advantageous.
• Basic understanding of PV generation, BESS dispatch, state of charge, grid export limits, curtailment, degradation, availability, and performance metrics.
• Strong analytical, problem-solving, documentation, communication, teamwork, and learning agility skills.
• As part of the selection process, candidates may be required to complete a case study, technical assessment, or modelling exercise.
• Willingness to commit to a two-year graduate development programme and travel to project sites where required; a valid driver’s licence would be advantageous.

Additional Information

• Incomplete CV’s and/or applications will not be considered. Your CV should be accompanied by your supporting documents.
• Closing Date: 03 October 2026.
• By submitting any personal information to the Company, the candidate unconditionally and voluntarily, consents to the processing of the submitted personal information for any and all purposes related to recruitment.
