      <Title>Staff Backend Engineer, Avatars</Title>
      <Description><![CDATA[<p>As a Staff Backend Engineer, you will work on the core systems powering Avatars and Generative Media, one of the most critical areas of Synthesia&#39;s product.</p>
<p>You will take ownership of the system design and architecture behind avatars, ensuring it remains scalable, reliable, and extensible as the product evolves.</p>
<p>You will design systems that support complex product requirements such as avatar versions, sharing across users and organisations, personalisation, and integration with voice and video pipelines.</p>
<p>You will play a key role in ensuring avatars function as a first-class entity across the platform, working closely with multiple teams to define how avatars are created, stored, and used throughout the product.</p>

<ul>
<li>Product and design to ensure system decisions align with user needs</li>
</ul>
<ul>
<li>R&amp;D teams to integrate model capabilities into production systems</li>
</ul>
<ul>
<li>Adjacent product teams such as Voices and Video Generation to ensure seamless integration</li>
</ul>
<p>You will take a long-term view of the system, ensuring that what is built today can support future iterations, increased scale, and new product capabilities.</p>
<p>You will act as a technical steward for the codebase, helping maintain high standards for structure, maintainability, and extensibility as the system grows.</p>
<p>In this role, you will have the opportunity to work on cutting-edge AI technology and contribute to the development of a leading AI video platform.</p>
