    Battery Storage Engineer – BESS

    Role Overview

    • A leading renewable energy developer is seeking a Battery Storage Engineer to support the design, development, and delivery of large-scale battery energy storage system (BESS) projects.
    • This role requires a technically strong engineer with deep, hands-on experience in large-scale battery storage projects, capable of contributing across the full project lifecycle—from early-stage feasibility through to execution and commissioning. The successful candidate will play a key role in integrating storage solutions into renewable energy projects, including hybrid (solar + storage) systems.

    Key Responsibilities
    Technical Design & Engineering

    • Lead and support the design of large-scale BESS projects, including system sizing, configuration, and optimisation.
    • Develop and review technical specifications, single-line diagrams, and system layouts.
    • Support the integration of battery systems with solar PV and grid infrastructure.

    Project Development Support

    • Provide technical input during feasibility studies, site assessments, and project development phases.
    • Evaluate technology options, suppliers, and OEM solutions for BESS applications.
    • Support bid preparation and technical submissions for project opportunities.

    Execution & Delivery

    • Work closely with EPC contractors, OEMs, and project teams during construction and commissioning phases.
    • Review and approve detailed engineering designs and ensure compliance with project requirements.
    • Monitor project progress from a technical perspective, identifying and mitigating risks.

    Grid & System Integration

    • Support grid connection processes, including studies and compliance with grid codes.
    • Coordinate with grid operators, consultants, and internal teams on interconnection requirements.
    • Ensure optimal performance and reliability of integrated energy systems.

    Stakeholder Collaboration

    • Collaborate with internal teams across development, commercial, and project delivery functions.
    • Engage with external stakeholders including consultants, contractors, and technology providers.
    • Provide technical guidance and support to non-technical stakeholders where required.

    Experience & Qualifications
    Essential (Non-Negotiable)

    • Minimum 5+ years’ experience in the renewable energy sector, with direct involvement in large-scale battery storage (BESS) projects.
    • Proven experience working across the lifecycle of large-scale storage projects (design, development, and/or execution).
    • Bachelor’s degree (BEng or BScEng) in Electrical or Mechatronic Engineering.
    • Strong understanding of battery technologies, energy management systems, and grid integration.
    • Experience working with EPC contractors, OEMs, and multidisciplinary project teams.

    Desirable

    • Experience with hybrid renewable energy projects (solar PV + storage).
    • Familiarity with South African grid code requirements and grid connection processes.
    • Exposure to power system studies (load flow, stability, etc.).
    • Professional registration (or progress towards) with ECSA.

    Key Attributes

    • Strong analytical and problem-solving capability with attention to technical detail.
    • Ability to operate effectively across both design and project execution environments.
    • Comfortable working in a fast-paced, delivery-focused environment.
    • Effective communicator with the ability to engage across technical and non-technical teams.
    • Self-driven and accountable, with a focus on delivering high-quality engineering outcomes.
