Captur are hiring a

UX Engineer Intern (On-Device Computer Vision)

About the role

The role focuses on the camera flow inside our clients mobile apps. We dont do single-photo verification - our models run over the live camera stream, every frame, in real time, on the users phone. Whatever the user sees, and feels while theyre framing the shot is the focus of the problem youd be working on.

The interesting problem: model output is probabilistic and noisy, the scene is different every time, and the user is operating in the real world - on foot, in the rain, gloves on, one hand free. Visual UI alone usually isnt enough. Haptics, symbolic cues (think game HUD), and visual feedback all need to play together, and at any given moment you have to decide what to surface, on which channel, in what order.

What youll do

• Real-time feedback design. A scooter rider photographs a finished trip in the rain. The camera streams at ~30fps; the on-device model gives a confidence-shaped output per frame. The job is to turn that stream into something the rider can act on inside their visual loop - usually under 300ms.
• Parallel feedback channels. Visual, haptic, symbolic. Each has different bandwidth, different attentional cost, different latency. Mapping the right signal to the right channel - and prioritising across them when several things are wrong at once - is the headline challenge.
• Generalising across scenes. A courier at a doorstep, a rider at trip-end - same SDK, different scenes, different priorities. We want a feedback system that generalises rather than one hand-tuned per client.
• End-to-end ownership. Youd scope, prototype, ship, and measure one piece of work over the internship. A 1:1 mentor helps you scope it in week one and reviews throughout.

Qualifications

Required

• Some experience programming, e.g. Javascript (React Native, Typescript), Swift, Kotlin, Python.
• Some interaction design, motion design, or HCI work - coursework, a side project, or self-directed study. Send us one example in your application.

Useful

• Coursework or projects in computer vision, ML, or signal processing.
• Front-end (TypeScript / React) - useful for our internal debug tools and visualisations.
• Prototyping tools (Figma, Origami, ProtoPie, or hand-rolled HTML / SwiftUI).
• Game UI design, aviation HUD design, accessibility/multi-modal interface work, or anything else where youve thought about feedback beyond visual UI.
• User research methods - think-alouds, contextual inquiry, watching your flatmate use your project.
