Descripción del trabajo - Senior OT Engineer

This is a senior operational technology engineering role supporting critical renewable energy infrastructure across distributed sites and remote operations environments.
You’ll take ownership of complex OT networking and security challenges, providing advanced troubleshooting and technical leadership.
The role combines network architecture, firewall administration, segmentation, cybersecurity, SCADA connectivity, and infrastructure reliability.
You’ll work closely with Security, IT, Operations, engineering teams, and customers to maintain secure and resilient environments.
Your expertise will directly contribute to the availability, performance, and protection of mission-critical renewable energy assets.
The position offers exposure to modern OT environments at the intersection of renewable energy, industrial systems, and cybersecurity.
You’ll operate with significant autonomy while contributing to a collaborative, technically demanding, and fast-moving integral environment.

Accountabilities

- Lead the troubleshooting and resolution of complex OT network and infrastructure issues, providing Tier 3 support for high-impact incidents.
- Design, implement, maintain, and improve OT network architectures across distributed customer sites and remote operations/control center environments.
- Configure, manage, and troubleshoot next-generation firewalls, particularly Fortinet and Palo Alto platforms, including VPNs, NAT, security policies, and network segmentation.




- Ensure secure separation between IT and OT environments through effective segmentation and security architecture.
- Monitor and optimize network performance, availability, reliability, and connectivity across multiple facilities.
- Support incident response, technical investigations, and root cause analysis for network and cybersecurity events.
- Participate in network equipment patching, upgrades, lifecycle management, and technology refresh initiatives.
- Work collaboratively with Security, IT, Operations, engineering teams, and customers to establish and implement technical standards.
- Support SCADA, RTAC, and industrial communication environments, including technologies and protocols such as Modbus, DNP3, and OPC-UA.
- Prepare project and work-order status updates and participate in internal and customer-facing meetings as required.

- 5–10+ years of experience in networking,



OT engineering, IT infrastructure, or closely related technical roles; candidates with a university-level technical degree or at least 3–5 years of relevant IT network experience may also qualify.
- Proven experience supporting multi-site or distributed environments, preferably within energy, utilities, manufacturing, industrial, or other mission-critical environments.
- Strong knowledge of Layer 2 and Layer 3 networking, including VLANs, routing, failover, redundancy, and Spanning Tree Protocol technologies such as STP, RSTP, and MSTP.
- Hands‑on expertise with Fortinet/FortiGate firewalls and Palo Alto firewalls, including configuration, troubleshooting, policies, NAT, VPNs, and administration.
- Strong Cisco networking experience, including switches, routers, ACLs, and routing protocols such as BGP and OSPF.
- Experience with site-to-site and remote-access VPNs, network segmentation, and Zero Trust concepts within OT environments.
- Ability to use packet analysis and troubleshooting tools such as Wireshark and tcpdump.
- Understanding of SCADA systems, RTACs, industrial protocols, and OT networking architectures.
- Professional experience in at least two relevant areas such as server and operating system management, network and infrastructure design, cybersecurity, remote infrastructure support, data storage and recovery, Tier 2/Tier 3 networking, telecommunications, or IT infrastructure engineering.
- Experience with regulated or standards-driven environments, with exposure to NERC CIP, NIST, ISO 27001, PCI-DSS, or similar frameworks considered valuable.
- Ability to read and interpret electrical,
