IT Systems Administrator in Chichester

Location: Chichester / West Lavant (Full-time, Onsite)

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.

The Role

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.

What You’ll Be Doing

• 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)
• Managing SaaS tools (Google Workspace, Slack, Notion, etc.)
• 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

What You’ll Bring

• Strong Linux (Ubuntu) administration experience
• 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

Most importantly:

• You’re comfortable owning problems end-to-end
• You’re methodical and process-driven
• You’re confident working in unfamiliar or evolving technical environments

Nice to Have

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

Who You Are

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

• 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
