IT Systems Administrator in Chichester

Chichester, United Kingdom | Posted on 30/04/2026

Be the person who owns and shapes IT in a scaling, engineering-led company. At sees.ai, we’re hiring our first in-house IT Systems Administrator to take full ownership of internal IT across a growing team building and operating autonomous drone systems. This is a hands-on role where you’ll be responsible for everything from day-to-day support through to identity, security, and infrastructure — with the autonomy to improve how things are done as the company scales.

You won’t be stepping into a fully built IT function. You’ll be building and evolving it — working across a modern, cloud-first stack, and supporting both standard corporate systems and more unusual infrastructure connected to real-world operations. Based full-time at our West Lavant site, you’ll work closely with engineering, operations, and the wider business — with real visibility, responsibility, and impact from day one.

You’ll be the single point of contact for IT across the business. This is a broad, hands-on role covering:

• Internal IT support and user experience
• Identity and access management
• Security monitoring and incident response
• Corporate network and endpoint management
• Continuous improvement of systems, tooling, and processes

You’ll also support parts of our bespoke networking and infrastructure used in drones and vehicles — a genuinely interesting and non-standard environment where IT and real-world systems intersect.

• Providing first-line support across macOS, Windows, Linux, iOS, and Android
• Managing onboarding/offboarding, device setup, and access provisioning
• Administering identity and access (SSO, RBAC, joiners/movers/leavers)
• Maintaining and improving security monitoring (SIEM, alerting, patching)
• Responding to security alerts and incidents in a structured, methodical way
• Running a zero-trust network environment
• Supporting internal infrastructure, including non-standard operational systems
• Building documentation, processes, and user guidance
• Driving cybersecurity best practice and supporting standards such as ISO27001 and Cyber Essentials

• Confidence across macOS and Windows in a mixed environment
• Experience with identity platforms (Jumpcloud, Okta, or similar)
• Familiarity with SIEM tools, security monitoring, and patch management
• Understanding of cybersecurity principles and compliance
• Ability to work independently and prioritise without close oversight
• You’re methodical and process-driven
• You’re confident working in unfamiliar or evolving technical environments

• Experience in a startup or scaling company
• Exposure to GCP or cloud infrastructure (IAM, logging, access controls)
• Networking fundamentals (VPNs, routing, firewalls)
• Exposure to Kubernetes or modern infrastructure tooling

This role carries broad access across company systems — identity, network, communications, HR, and finance — so trust and judgement are critical.

• Trustworthy and discreet — comfortable handling sensitive systems and data
• Process-driven — you document and follow structured approaches consistently
• Calm under pressure — you diagnose issues methodically, especially during incidents
• Self-sufficient — you can own and resolve problems without relying on a large team
• Clear in communication — able to support non-technical users effectively
• Curious and proactive — you stay current and take security seriously

• Be the first IT hire — with full ownership of how IT is built and run
• Work across a modern, cloud-first stack with real responsibility
• Gain exposure to non-standard systems and infrastructure you won’t find elsewhere
• See the direct impact of your work across the entire business
• Join a company at a stage where your work will directly shape how it scales
• Work from our West Lavant site in the South Downs — a unique environment with excellent on-site facilities (gym, pool, tennis courts, café, and more)

We develop and operate autonomous aerial systems used to inspect critical national infrastructure. Our technology enables complex inspection missions to be carried out safely, repeatedly, and at scale in real-world environments. You’ll join at a pivotal stage, where the company is scaling and the systems you build and support will directly enable that growth.
