Senior Web Designer Jobs in Renton, WA (NOW HIRING)

Agentic development is redefining how software gets built, and Kiro is at the center of it. Kiro is an agentic AI from AWS that turns prompts into structured requirements, designs, and sequenced tasks, then implements them with parallel agents that verify correctness. It's available as a desktop IDE, a CLI, a web app, a mobile app, and Kiro Crew (an open-source persistent development workspace), all powered by one unified agent harness.
We're looking for a Senior UX Designer to help shape this experience

You'll initially focus on Kiro Crew and Mobile, two surfaces with distinct design challenges and significant room to define the experience. You'll build deep understanding of the developer audience while leading hands-on design work: concept framing, interaction patterns, and shipping real improvements that inform longer-term product direction.
The design challenges here are unlike traditional developer tools: How should a developer steer an autonomous agent. What does a spec-driven workflow feel like across an IDE, a terminal, a browser, and a phone

How do you build trust in AI that writes and validates code on your behalf?
You excel in the early, ambiguous stages of design: concept modeling, ecosystem mapping, user story development, and framing the experience before pixels are ever pushed. You know how to set up a problem space so that the right solutions emerge. You are equally strong in execution, iterating rapidly and prototyping in whatever tool fits the moment.

You adapt your approach based on the problem, the timeline, and the team. We value designers who bring their own perspective and working style. What matters is the quality of thinking and the impact of the outcome, not conformity to a single methodology.
You will collaborate with product teams, engineering teams, and executive leadership to identify and execute on opportunities, serving as the voice of the developer with senior leadership.
If you want your design work to shape how millions of developers build software with AI, we'd love to hear from you.
Key job responsibilities
- Go deep on audience understanding: conduct and synthesize research to build rich mental models of how developers think, work, and adopt agentic tools
- Lead concept design and early-stage framing: ecosystem maps, concept models, user stories, journey frameworks, and experience principles that set the foundation for product direction
- Own and drive the end-to-end design process for major features across the Kiro platform (IDE, CLI, Web, Mobile, and Kiro Crew)
- Shape the UX of agentic workflows including spec-driven development, autonomous mode, parallel agents, hooks, and correctness verification
- Iterate rapidly and prototype at the right fidelity, from paper sketches and concept storyboards to high-fidelity interactive prototypes, choosing the right tools and methods for each challenge
- Design cohesive experiences across desktop, terminal, browser, mobile, and open-source surfaces while respecting the unique interaction paradigms of each
- Partner with product management and engineering to influence strategy through strong design rationale and customer advocacy
- Mentor junior designers and define scalable design patterns that raise the bar across the team
About the team
You'll join a team of designers and researchers embedded directly in the Kiro product organization

We sit alongside product and engineering as one team, which means design has a seat at the table from strategy through shipping. We have dedicated UX research support and work in close collaboration with our researchers, so design decisions are grounded in real customer insight, not assumptions.
Our team covers the full Kiro product suite: IDE, CLI, Web, Mobile, Kiro Crew, the Kiro agent, and platform capabilities. We support each other's growth, share work openly, and believe that the best design comes from people who bring diverse perspectives and their own way of working

If you thrive in an environment where you have real ownership, close partnership with research, and the autonomy to choose how you approach a problem, you'll feel at home here.
