Our LINQ platform is the software that plans, schedules, and drives life-science labs. Our clients run labs for cancer diagnostics, drug discovery, cell manufacturing, synthetic biology and more. This role owns the interface to the lab — not just the UI, but every surface someone builds on or acts through: the app a scientist touches, the APIs and SDK an integrator builds on, the CLI an engineer scripts with, the agent surface a model acts through. Most product interfaces are forms over a database. Ours front a physical world that changes by itself — robots act, schedules change, instruments fail — and every one of those surfaces has to keep its user genuinely in control. We're building the next generation of our interfaces — AI-native from the ground up: personalised to role and behaviour, UI generated on the fly where it earns its place, and agents working in the product alongside the people using it. This is a role for someone user-obsessed — the platform underneath is...
