ABOUT THE POSITION

We are seeking a Systems Engineer to focus on tackling the industry's greatest challenges at the intersection of renewable energy networks, distributed control, and cybersecurity across Fluence’s global installed fleet. This role is about identifying and closing gaps in system performance, network architecture, and security posture while feeding critical lessons learned back into product development.

WHAT IS GLOBAL OPERABILITY AND SYSTEMS ENGINEERING:

This team is the technical backbone of Fluence’s battery energy storage system (BESS) product maturity and lifecycle excellence. The team owns the ongoing reliability, performance, and continuous improvement of products and customer sites after launch — bridging engineering design intent with real-world operations. We troubleshoot complex field issues, manage design changes, drive root-cause analysis, and partner across manufacturing, supply chain, and service to ensure our products evolve safely, efficiently, and profitably.

IN THIS POSITION, YOU WILL:

• Troubleshoot and resolve BESS site system issues – including using knowledge of Linux, MQTT, Modbus, OPC-UA, XRT, or other languages and protocols – to maintain reliable and scalable connections and communications of distributed control components

• Look across the global fleet’s performance from a network and cybersecurity standpoint, identifying systemic issues and improvement opportunities.

• Develop and implement solutions to known gaps, ensuring resilient and secure fleet operation.

• Influence products in development by embedding technical lessons learned from the field into next-generation design.

• Recognize that in many markets, network architecture and cybersecurity are directly tied to commercial success and even broader geopolitical considerations.

• Help quantify issues, propose solutions, and execute fixes that strengthen both our deployed systems and our future offerings.

• Develop and manage patch and change management processes for in-service assets’ firmware and cyber components

KEY RESPONSIBILITIES

• Investigate and resolve complex BESS site system issues involving Linux environments, communication protocols like Modbus, MQTT, OPC-UA, or others, Cisco networking gear (switches, firewalls), and secure communications.

• Perform Linux-level troubleshooting (services, logs, system performance) to isolate and document issues before escalating to Product teams.

• Configure, troubleshoot, and maintain Cisco switches/firewalls including VLANs, routing, and ACLs

• Collaborate with product engineering and cybersecurity specialists to align with operational technology (OT) cybersecurity standards and drive best practices across the fleet.

• Manage and support cybersecurity and patching processes, including network device updates, firmware patch management, and validation of secure deployments.

• Partner with software teams to assess vulnerabilities, validate updates, and ensure secure deployment across the fleet.

• Translate fleet findings into actionable design considerations for future products.

WHAT WILL OUR IDEAL CANDIDATE BRING?

• 8+ years' experience in Systems, Reliability, or Sustaining Engineering in complex/critical infrastructure and distributed systems (energy, aerospace, industrial).

• Strong expertise in Linux administration: logs, services, scripting, troubleshooting.

• Hands-on knowledge of Cisco networking: switch/firewall config, ACLs, VLANs, routing, VPNs, troubleshooting tools (Wireshark).

• Familiarity with OT cybersecurity principles (segmentation, secure protocols, access controls).

• Awareness of cybersecurity standards such as NERC CIP, IEC 62443, ISO 27001 — direct experience preferred, willingness to grow required.

• 8D problem solving expertise or other root cause analysis methods

• Excellent communication skills across engineering, product, and commercial teams.

PREFERRED

• Certifications a plus (Linux+, Sysadmin, CCNA, CISSP, or equivalent).

• Experience in industrial control systems, BESS, or other mission-critical hardware/software systems.

• Experience in BESS, renewable energy, or related fields

• Familiarity with Agile/Scrum practices.

WHO YOU ARE

• Growth mindset — eager to improve today’s fleet while shaping tomorrow’s designs.

• Systems thinker — you connect Linux, networking, and cybersecurity into holistic solutions.

• Collaborator — skilled at working across sustaining, product, and field teams.

• Bias for action — you don’t just find gaps; you close them
