IT Infrastructure & Security Engineer

As IT Infrastructure & Security Engineer at Fiducial, you will be the person who makes sure our technology — and the people building it — can operate securely, reliably, and without friction, whether that's a laptop for a new hire, a cloud environment for the dev team, or the deployment pipeline that gets our software onto a UAV in the field. This is a broad, hands-on role for someone who takes ownership rather than waits for a ticket. You'll move fluidly between day-to-day IT operations, security policy and hardening, and infrastructure/deployment engineering — picking up whatever tools and skills the problem in front of you requires. In a defence-adjacent start-up, the person in this seat isn't just keeping the lights on; you're building the operational backbone that lets a small team ship high-stakes software fast, safely, and reliably. We're not looking for someone who already has a checklist of tools memorised — we're looking for someone with the judgment, curiosity, and grit to figure out the right tool, learn it, and own it.

Responsibilities

General IT operations — provisioning and maintaining devices, accounts, and access; onboarding/offboarding; vendor and license management; being the go-to person when something technical breaks.; Security ownership — defining and continuously improving IT security policy, access controls, and risk assessments across cloud, on-premise, and edge-deployment environments.; Infrastructure & deployment pipelines — building and maintaining CI/CD pipelines and the hybrid cloud / on-premise / edge infrastructure that gets our software from code to field-deployed reality, with speed and scalability in mind.; Monitoring & reliability — setting up logging, monitoring, and alerting so the team knows about problems before they become incidents.; Network & on-premise administration — maintaining secure, scalable connectivity between our office, cloud environments, and field-deployment operations.

Requirements

A generalist mindset: comfortable moving between IT operations, security, and infrastructure engineering rather than specialising narrowly in one.; Solid grounding in Linux-based systems, Docker/containers, and scripting (Python, Bash) — with the ability to pick up new platforms and tools as needed (e.g., Kubernetes, Azure or other cloud platforms, CI/CD tools such as GitHub Actions, GitLab CI, Jenkins, or ArgoCD, monitoring stacks such as Prometheus/Grafana/ELK/Loki).; A genuine interest in security — you think about risk and access control by default, and you're keen to build real expertise here, whether or not you already have it.; Familiarity with network administration and on-premise IT infrastructure.; High degree of autonomy, ownership, and problem-solving grit — you enjoy making complex systems work smoothly, and you don't wait to be told what to fix.; Strong collaboration and communication skills, working closely with developers, engineers, and (where relevant) external partners.; Full-time availability (40 hours per week).

Nice to have

Prior exposure to defence, aerospace, or other high-compliance/high-stakes environments.

Benefits

Money, of course.; 25 vacation days per year.; Reimbursed travel expenses and a company laptop.; (Really) flexible working hours, with the option to work from home 2 days per week (when not abroad).; Working in an international, world-class team of engineers and entrepreneurs solving real-life problems with amazing technology.; Large freedom in how you work and implement solutions — project ownership is incredibly important to us.; Responsibility over the things you implement — you are the expert on what you build.
