We are using and creating technology to transform operations at sea to enable people and the planet to thrive.
We are open-minded and fearless in our approach to innovation and don't believe in boundaries. We challenge everything and have massive ambitions to drag aging industries into the tech era.
We take safety, equality and education very seriously, and our responsibilities don't stop at our front door. Our business is built on the belief that there's definitely a more environmentally responsible way to operate at sea.
We employ people who share our core values. We expect our people to be courageous, trustworthy, and conscientious, driven by a desire to do the right thing. We strive for excellence, work collaboratively, and are genuinely excited by our work.
We offer opportunities for our people to develop beyond their role and span a multitude of disciplines. These are open to all, regardless of background and experience level. Working with us means being part of a team that is harnessing technology and creativity to disrupt a traditional industry.
We are not your average workplace.
We are seeking a Senior Network Architect to design, build and secure the networking, communications, and data pathways that underpin our USV and AUV systems. This is a hybrid role combining:
Systems engineering (requirements, architecture, integration)
Network & comms engineering (routing, radios, RF, protocols, data links)
Network security considerations
You will ensure reliable, secure, high‑performance data communication between autonomous platforms, motherships, remote operators, cloud infrastructure, and onboard sensors.
This role is ideal for someone keen to deliver secure, reliable complex networks in challenging marine environments.
What you will be doing
Act as Subject Matter Expert for network architecture.
Architect, design and document the end-to-end communications architecture for USVs and AUVs (radio, satellite, cellular, mesh, Wi-Fi, acoustic systems).
Define and maintain IP architectures, VLANs, firewall rules, QoS, bandwidth allocation, and encryption schemes.
Produce communications system requirements, ICDs, test plans, and verification documentation (lean and pragmatic).
Conduct trade studies for new comms technologies (e.g., new satcom services, mesh systems, acoustic modems).
Work closely with mechanical, electrical, software, and autonomy engineers to ensure seamless integration.
Provide technical expertise to operations and project teams.
Help design tailored communication solutions for specific customer missions or environments.
Ensure network architectures can meet security requirements for specific customer missions and environments.
Who you are
Degree in Networking, Telecommunications, Electrical/Systems Engineering, Computer Engineering, or similar.
Strong experience with IP networking (routing, switching, VLANs, firewalls, QoS, VPNs).
Familiarity with radio and wireless communications (RF fundamentals, antennas, propagation).
Hands-on experience configuring network hardware (Cisco, MikroTik, Ubiquiti, Peplink, etc.).
Understanding of satellite, 4G/5G, Wi-Fi, or RF mesh communications.
Experience building / managing cloud hosted services
Comfortable building, testing, and troubleshooting real hardware.
Experience with Linux networking tools.
Experience of secure network architecture and implementation, including cybersecurity principles (secure comms, certificate management, hardening).
Desirable
Experience with Ansible, AWS, OpenWRT, WireGuard and RouterOS.
Marine communication systems experience (maritime radios, AIS, acoustic communications).
Experience with networking for autonomous systems (UAVs, robots, mobile platforms).
Familiarity with ROS/ROS2 networking, DDS, or middleware.
Experience with field deployments and remote operations.
Given the nature of the work, this role requires you to obtain and maintain the appropriate level of UK national security clearance. You must be willing and able to undergo the necessary security vetting process, and continued employment in the role may be subject to maintaining the required clearance. Security vetting will be conducted in accordance with the requirements and standards set by United Kingdom Security Vetting (UKSV). Further information on UK security clearance levels, eligibility, and the vetting process can be found on the UK Government website: United Kingdom Security Vetting: Applicant
Salary: The salary varies for this position as we are recruiting in multiple regional locations and job grades. The salary process is based on skills, abilities, and experience required.
