Job summary

aion is the enterprise AI platform offering a full-stack solution for building, fine-tuning, and deploying AI at scale. We are a fast-growing startup with teams across the US, UK, and India, hiring a product designer to turn vague problems into intuitive flows and pixel-perfect screens.

You’ll own the visual layer, specify interactions, evolve the design system, and test with real users to iterate toward a flawless product experience. Equity and flexible work options are offered.

Qualifications

• 6+ years in product design, with complex products shipped end to end.
• User research: interviews, contextual inquiry and usability testing, planned and run yourself and turned into decisions.
• Problem framing: user needs, jobs to be done and success measures defined before any screen is drawn.
• End-to-end journeys: journey maps and service blueprints covering every touchpoint, handoff and failure path.
• Task flows and wireframes that account for every branch, edge case and error, tested before visual design.
• Information architecture: content models, navigation and labelling, validated with card sorts and tree tests.
• Interaction design: mental models, affordances, feedback and system status, consistent across the product.
• Evaluation: heuristic reviews and usability metrics such as task success, time on task and error rate.

Responsibilities

• Turn ambiguous problems into clear flows, information architecture and interaction models.
• Design every state of every screen: empty, loading, partial, error and the edge cases nobody listed.
• Own the visual layer: typography, layout, colour, iconography and hierarchy.
• Specify interactions and motion precisely enough that engineers ship them as designed.
• Build and evolve the design system.
• Review what ships at 1× and 2×, and catch the 1 px misalignment, the wrong easing and the clipped label before anyone else does.
• Test with real users and iterate until nothing is left to remove.
