Job Summary

Join Ardor as a founding Design Engineer in Singapore, creating seamless UX for a versatile AI-driven cloud platform that automates complex workflows and delivers impactful outcomes across diverse domains.

Full remote role, no office required.

Responsibilities

• Design and deliver user interfaces using Figma to create intuitive, user-centered designs for complex AI-driven workflows
• Develop and ship front-end components with React to implement seamless, responsive user experiences
• Apply strong design judgment and attention to detail to craft polished, high-quality product interfaces
• Navigate ambiguity and complex system requirements to iterate and refine design solutions effectively
• Collaborate within a founding team environment to drive product innovation and solve challenging UX problems

Preferred competencies and qualifications

• Experience working in early-stage startup or founding team settings
• Passion for high craftsmanship and design excellence
• Ability to adapt quickly to evolving product needs and chaotic environments

A few things Ardor done:

• Enterprise: spun up its own service to reach into the company's VPN-protected network, pulled the data, and stood up a Metabase instance wired to it — fully under Ardor's control. Dashboards, SQL, ad-hoc questions, plus code, infra, and support work — all now one prompt away. With a single integration a company gets a company-level AI agent that's trivial to roll out — just grant access the way you already do. And at the same time it's a personal agent for every employee, covering every domain, always in context of what, where, and how.
• PhD verifying computational chemistry papers — weeks of work collapsed into an hour
• Non-coder shipping a 3-tier production app on Kubernetes (React + FastAPI + Postgres)
• Aerospace engineer turning a napkin math model into working MATLAB code
• Guitarist learning a new song — Ardor built a chord trainer tailored to the track
• Founder needing market insights — just ran the research end-to-end

Same platform. Same agent.

Agentic systems have wild emergent effects — every new tool is a non-linear jump in what they can do.

Tools aren't the interface. Outcomes are.

Designing for a product that can solve such a wide range of tasks is the hardest — and most interesting — UX problem I can think of. I need someone who can make it feel effortless.
