      <Title>Staff Fullstack Engineer, Avatars</Title>
      <Description><![CDATA[<p>You will work on end-to-end product features across the Avatars and Generative Media domain, building experiences that sit at the core of Synthesia&#39;s product.</p>
<p>You will design and deliver features that combine frontend, backend, and AI model capabilities, helping users create and customize avatars, generate content, and interact with generative systems in a reliable and intuitive way.</p>
<p>You will take ownership of features from idea through to production, working with loosely defined requirements to scope, prototype, and ship solutions that deliver real user impact.</p>
<p>You will work directly with AI models (both third-party and in-house), evaluating what is possible, understanding reliability constraints, and shaping product decisions based on those capabilities.</p>
<p>You will build across the stack, including:</p>
<ul>
<li>Backend systems to support feature logic and model integration</li>
</ul>
<ul>
<li>Frontend experiences that allow users to interact with generative features</li>
</ul>
<ul>
<li>End-to-end workflows that connect user input, model output, and product behavior</li>
</ul>
<p>You will frequently work on 0 to 1 problems, such as introducing new avatar capabilities or generative features, where experimentation and iteration are critical to success.</p>
<p>You will collaborate closely with product and design to:</p>
<ul>
<li>Translate user problems into experiments and features</li>
</ul>
<ul>
<li>Validate what works reliably with underlying models</li>
</ul>
<ul>
<li>Iterate quickly based on feedback and real usage</li>
</ul>
<p>You will ship features behind feature flags, measure outcomes, and continuously refine based on product and user signals.</p>
