About the role
You will work onend-to-end product features across the Avatars and Generative Media domain, building experiences that sit at the core of Synthesia’s product.
You will design and deliver features that combinefrontend, backend, and AI model capabilities, helping users create and customize avatars, generate content, and interact with generative systems in a reliable and intuitive way.
You will take ownership of features fromidea through to production, working with loosely defined requirements to scope, prototype, and ship solutions that deliver real user impact.
You will work directly withAI models (both third-party and in-house), evaluating what is possible, understanding reliability constraints, and shaping product decisions based on those capabilities.
You will build across the stack, including:
Backend systems to support feature logic and model integration
Frontend experiences that allow users to interact with generative features
End-to-end workflows that connect user input, model output, and product behavior
You will frequently work on0 to 1 problems, such as introducing new avatar capabilities or generative features, where experimentation and iteration are critical to success.
You will collaborate closely with product and design to:
Translate user problems into experiments and features
Validate what works reliably with underlying models
Iterate quickly based on feedback and real usage
You will ship features behindfeature flags, measure outcomes, and continuously refine based on product and user signals.
What we’re looking for
You have experience building and shippingfull-stack product features end-to-end in production environments.
You are comfortable working across bothfrontend and backend, and can independently deliver a feature from concept to implementation.
You have a strongproduct mindset and can take ambiguous problems, define scope, and iterate towards solutions that deliver user value.
You are comfortable working in0 to 1 environments, experimenting, prototyping, and learning quickly rather than relying on detailed upfront specs.
You can evaluate technical feasibility andmake pragmatic trade-offs, especially when working with imperfect or evolving systems such as AI models.
You care aboutreliability and user experience, aiming to build features that work consistently in real-world usage.
You are confident collaborating with product and design, including pushing back when something is not feasible and proposing better alternatives.
You are willing to debug and work across the stack, wherever the problem is.
Experience withAI or ML-powered products, experimentation workflows, or feature flagging is a plus, but not required.
