Battery Storage Engineer – BESS at AltGen South Africa

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.
