User Experience Designer

About us
Attuned helps companies build happier and more productive workplaces through science-backed data and AI, uncovering deep and actionable insights on what their employees need to be more engaged and fulfilled at work.
Born out of our founder’s vision to fix the world of work, Attuned was developed by a team of psychologists to measure 11 key motivational factors through a 55-question survey. That forms the basis for a suite of at-a-glance insights and tailored actions and “nudges” that help managers communicate better and remove the guesswork behind motivating individuals and teams effectively. In turn, that builds a culture of inclusivity, increases psychological safety, and creates happier and more productive workplaces.
In short, Attuned is transforming the way the world works by helping shape work cultures built on transparency and authentic connection, and, ultimately, by making work more meaningful.
About the role
We’re looking for a UX designer to take ownership of our product design while our current designer is on maternity leave. This is a 1-year fixed-term contract with possible extension.
You’ll be the sole designer on a small, fast-moving team. That means you’ll make and defend design decisions independently, without a design peer to consult. You’ll work directly with product and engineering to shape what we ship.
This is an AI-native design role. We use AI tools like Claude Code to generate working prototypes directly, sometimes bypassing Figma entirely. Engineering uses AI-assisted coding, which compresses the gap between design intent and shipped product. If you’re energized by the idea that a prototype can be generated in minutes rather than days, this role is for you.
The product team conducts user interviews and research (partly due to language considerations) and also proposes initial design concepts. Your job is to receive those findings and concepts, evaluate them critically, improve them, and give final design approval. That requires someone with strong opinions who can make autonomous calls.
What you'll do
Own UX for the Attuned product for the duration of the contract
Review user research and interview findings from the product team and translate insights into design decisions
Evaluate and refine designs proposed by product, and give final design approval on their concepts
Create designs using AI tools like Claude Code for rapid HTML prototyping and generative exploration
Write and iterate on PRDs alongside product and engineering
Maintain and evolve the existing design system
Collaborate directly with engineers in an AI-assisted workflow where the designer is often hands-on with output
Requirements
Must have
Strong, opinionated design thinking. You can confidently make and defend design decisions on your own
Comfortable with ambiguity and rapid iteration
Willing to use AI tools for design exploration and prototyping
Can write clear product specs and PRDs
Basic HTML/CSS literacy, enough to evaluate and adjust AI-generated output
Can interpret research findings and translate them into design direction
English at business level
Nice to have
Prior experience with AI-assisted design workflows
Figma proficiency (still useful, just not the only tool)
B2B SaaS or HR tech experience
Data literacy: you can read analytics dashboards and interpret engagement metrics
Startup experience, used to wearing multiple hats
Familiarity with design systems at a component and token level
Japanese at conversational level
What we offer
AI-native workflow: AI tools are a standing part of your daily design process here
Real ownership: You’re the sole designer. Your decisions directly shape the product, with no layers of approval to navigate
Remote and flexible: Work remotely with flexible hours, plus one to two in-person team meetings a month in the Tokyo area
Flat, autonomous culture: A small team with minimal hierarchy. We value trust, kindness, and quiet professionalism
Startup pace: Direct collaboration with engineering and the founders, fast iteration cycles, real impact on the product
Standard benefits: Health insurance, pension, paid vacation (prorated for the contract duration)
Applications without a portfolio will not be considered.
