<div>&nbsp;</div>
<div>This role is highly impactful and hands-on. While specific responsibilities will scale with your level, the core requirement is to take full ownership of the end-to-end design process, delivering exceptional user experiences and shaping how our AI-powered products help solve complex real-world problems.

</ul>
</div>
<h4><br>Design Practice &amp; Systems</h4>

<li>Evaluate tooling and approaches that improve velocity, quality, and collaboration with product/engineering.</li>
<li>Maintain hygiene around file structure, documentation, and process to ensure design remains a scalable discipline.</li>
<li>Apply a systems approach to design foundational capability, empowering our Solution Engineers to rapidly create UI and workflows against new customer problems at speed.</li>
</ul>
</div>
<h4><br>Collaboration &amp; Stakeholder Influence</h4>
<ul>
<li>Work closely with product, researchers, customer success engineers, and developers to deliver usable, valuable, feasible solutions.</li>
<li>Run or participate in design thinking workshops and partner with discovery researchers to facilitate user research and understand the 'why'.</li>
<li>Support early product framing by translating research, technical insight, and feedback into clear design direction.</li>
<li>Present design decisions clearly to internal stakeholders—both technical and non-technical.</li>
<li>Provide team leadership, design mentorship, and peer review for other designers (especially for Senior and Principal levels), supporting a healthy and high-quality design culture.</li>
<li>Be willing to travel to customer sites if required, a few times per year.</li>
