The engineer will support scientific research, manufacturing operations, and enterprise functions by enabling high-performance networking across cloud, on-premises, and edge environments.

Duties & Responsibilities

• Design and manage converged network infrastructure supporting both IT (enterprise systems, cloud platforms, user endpoints) and OT (lab instruments, SCADA systems, PLCs, IoT devices)
• Implement and maintain secure segmentation between IT and OT networks to ensure compliance and reduce cyber risk
• Monitor network performance across all environments, proactively identifying and resolving bottlenecks or vulnerabilities
• Collaborate with cybersecurity teams to enforce network security policies, including firewalls, NAC, IDS/IPS, and zero-trust architecture
• Support integration of laboratory automation systems, manufacturing execution systems (MES), and data acquisition platforms
• Manage network hardware lifecycle across office, lab, and production environments, including switches, routers, wireless access points, and industrial gateways
• Maintain detailed documentation of network architecture, configurations, and change management processes
• Participate in disaster recovery and business continuity planning for both IT and OT systems
• Provide support and advice to the IT Team as required, prioritising workload, including network-related incidents, remote diagnostics and on-site troubleshooting
• Stay informed on emerging technologies in both IT and OT networking, recommending upgrades and innovations

Qualifications

• Bachelor's degree in Computer Science, Engineering, or related field (Master's preferred)
• Certifications such as CCNP, CompTIA Network+, ISA/IEC 62443, Microsoft certification, or equivalent are highly desirable
• Deep understanding of networking protocols (TCP/IP, DNS, DHCP, VLANs, BGP, OSPF) and industrial communication standards (Modbus, OPC UA, Ethernet/IP)
• Experience with enterprise-grade and industrial-grade networking equipment (e.g., Cisco, Juniper, Hirschmann, Moxa)
• Familiarity with cloud networking (AWS, Azure) and hybrid architectures integrating IT and OT systems
• Knowledge of biotech-specific environments, including GxP compliance, laboratory automation, and regulated data flows
• Proficiency in network monitoring and diagnostic tools (e.g., SolarWinds, Wireshark, PRTG, NinjaOne)
• Scripting and automation skills (e.g., Python, PowerShell) for configuration and monitoring tasks
• Strong analytical and communication skills, with ability to translate technical concepts for diverse stakeholders

Desired experience and skills

• Proven experience managing integrated IT/OT network environments in biotech, pharmaceutical, or industrial settings
• Demonstrated ability to design secure, scalable networks that support both enterprise and operational systems
• Strong troubleshooting skills across diverse hardware and software platforms
• Experience working with multidisciplinary teams including scientists, automation engineers, and compliance officers
• Familiarity with regulatory frameworks such as HIPAA, ISO 27001, and GxP, and IT guidelines such as Essential 8 and NIST
• Ability to document and communicate network architecture and decisions clearly
• Commitment to innovation, continuous improvement, and operational excellence
