Volvo Energy Digital & IT

Digital & IT is a function within Volvo Energy. We support our customers transition to a carbon-free world through great Digital solutions and experiences that users love and enables customers to shift to fossil-free operations. We truly care about the customer’s business in terms of up-time, safety, productivity and of course 100% green energy supply. We aim at having industry-leading simplicity and usability for our digital services, such as routing, find-book-pay and charging operator systems. The energy transition will not come for free – but we are committed to support this transition by hard and dedicated work.

So - what are we looking for in this specific role?

Volvo Energy is providing a highly qualified digital platform, an Energy Management System (EMS), to control our Battery Energy Storage Systems (BESS).

We are now looking for Senior OT Network & Systems Engineer that will support in establishing cyber secure connectivity towards BESS units and the BESS digital twin using the appointed Volvo Energy Site Controller.

As the energy space rely on standards for interoperability between energy systems, like Modbus, IEC 60870-5, 61850 and DNP-3, you make sure that the IoT Edge solution is designed according to cyber security standards. You also ensure cyber secure connectivity to the Volvo Energy EMS solution via MQTT/OPC-UA as defined by the Volvo Energy target architecture.

You will work closely together with several different qualified teams to help design and build the solution and report functionally to the Volvo Energy Head of Enterprise architecture.

Key Responsibilities

In this role, you’ll take the lead in shaping the OT network architecture that powers our BESS units around the world. You’ll design secure, scalable network environments—everything from segmentation and VLAN structures to DMZ zones and redundancy strategies—both for our own products and for customer sites. As the technical owner of our OT networking landscape, you’ll create and maintain clear, high‑quality diagrams and documentation that bring structure to complex systems and ensure smooth integration with cloud platforms and external SCADA/EMS solutions.

A big part of your work will center around cybersecurity. You’ll define modern firewall rulesets built on IEC 62443 and zero‑trust principles, validate safe communication paths for industrial protocols like Modbus, and take full responsibility for the lifecycle of our OT firewalls. That includes firmware updates, patching strategies, redundancy testing, vendor coordination, and the automated deployment of configurations across our global BESS fleet using FortiManager.

You’ll also play a hands-on role in our production environments—diving into troubleshooting, leading root‑cause analysis, and contributing to cybersecurity assessments and audits that strengthen our defenses. Collaboration will be at the heart of your everyday work. You’ll partner with engineering teams at our assembly plants to ensure firewalls are configured correctly from the moment a unit is built, and you’ll work with Digital/IT teams to define secure, future‑proof IT–OT demarcation points. Along the way, you’ll also share your expertise with junior engineers and project teams, helping them grow while raising the overall technical bar.

Required Qualifications

• 7+ years in OT networking, industrial networking, or cybersecurity engineering roles.
• Strong experience with L2/L3 switching, routing, and industrial network design.
• Hands-on experience with firewalls (Palo Alto, Fortinet, Cisco, or equivalent).
• Solid understanding of industrial communication protocols (Modbus/TCP, IEC 61850, 60870-5, DNP3, MQTT and OPC-UA).
• Experience with network automation or configuration as code approaches.
• Familiarity with NERC CIP, IEC 62443, ISO 27001, or comparable cybersecurity frameworks.
• Solid understanding of cyber security, data management and modern integration technologies
• Experience from Agile development and DevOps practices
• Strong technology interest - always interested in learning more
• Ability to work in a heterogenous environment with several development teams, both inhouse and with players in the Digital Ecosystem.
• A “boots on the ground, get the job done” attitude
• Fluent in English, written and spoken.

Beneficial Qualifications

• Experience working with BESS, renewables, power systems, or plant-level OT environments.
• Knowledge of PLCs, RTUs, battery management systems (BMS), and SCADA architectures.
• Certifications such as CISSP, GICSP, GCIA, PCNSE, NSE, CCNP/CCIE.
• Experience and deep knowledge in developing IoT edge (ARM based) communication applications
• University degree relevant to the position: in electrical engineering, industrial engineering, computer science, Informatics or equivalent.

What Makes This Role Exciting?

At Volvo Energy, our size is one of our greatest strengths. Instead of being confined to a narrow scope, you’ll get hands-on exposure to every part of BESS development and the broader business. No two days look the same, and you’ll continuously grow your knowledge and influence.

We operate in a landscape where not everything is certain—and that’s exactly where we thrive. We experiment, learn fast, and aren’t afraid to take bold steps. Here, you’ll have a real opportunity to shape our ways of working and contribute directly to our long-term success.

Creating Success—For Yourself and Volvo Energy

You’re someone who turns ideas into action with structure, clarity, and purpose. As part of a new and rapidly evolving business area, your curiosity is essential. You’re eager to explore new technologies, tools, and methods—and you’re always looking for ways to elevate how we work.

Together, we’ll push boundaries, embrace innovation, and build something meaningful from the ground up.
