[Hiring] Senior Systems Security Engineer @Volta

Role Description

As Senior Systems Security Engineer, you will own how security infrastructure is built into Volta's infrastructure systems, from construction through commissioning to handover. Your focus is operational technology: BMS/PMS, cooling controls and infrastructure management systems across every DSX site.

This is an expert-level individual contributor role. Reporting to the Senior Director, Global Commissioning & Handover, you will set direction across delivery, commissioning and operations teams, and you will own the security acceptance bar every site must clear before it goes live.

What you will do

• Security requirements and architecture
  • Set Volta's OT and infrastructure security requirements for commissioning and handover, across all sites.
  • Define security architecture expectations that align to Volta’s high infrastructure security standards.
  • Set the supplier security requirements vendors are contracted against.
  • Own and track the security progress across Volta’s end to end security portfolio.
• Assurance and acceptance
  • Own the security acceptance criteria and decide when residual risk needs escalation or formal acceptance.
  • Lead security reviews and authorised testing of controls systems before handover.
  • Make sure patching, monitoring, incident response and recovery have clear owners at handover.
• Improvement
  • Use deployment and incident lessons to evolve the standards.

Qualifications

• Expert-level experience in OT or infrastructure cybersecurity in critical environments, typically 8+ years.
• A track record setting security requirements across multiple sites or teams, not only assessing single systems.
• Strong knowledge of controls networks, segmentation, identity and secure remote access.
• Experience balancing security against plant safety and availability, and making that trade-off clear to leadership.
• Experience working with enterprise security teams and influencing engineering and vendor decisions.

Nice to have

• Data centre BMS/PMS or industrial controls.
• OT security frameworks such as IEC 62443.
• Secure commissioning and handover across multiple sites.

Benefits

• Competitive salary based on the work you do here, not your previous salary.
• Equity in Volta, giving you the opportunity to share in the company's long-term success.
• Retirement/pension contributions.
• Comprehensive health, wellbeing and insurance benefits.
• Generous number of vacation days each year.
