Hr Manager in United States

Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US. As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations. Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow. The role... Synthesia's API and platform capabilities are quickly becoming the way developers embed AI video into their own products — automated training pipelines, localization workflows, customer-facing apps, and more. We're looking for our first Developer Advocate to make sure the developer world knows it, understands it, and gets building. This is a builder-and-storyteller role. You'll be the face and voice of the Synthesia API to the outside world — writing, coding, speaking, and showing up wherever developers already are — while also being the internal champion who brings their feedback back into the product. You won't just talk about what's possible with Synthesia; you'll build the sample apps, tutorials, and demos that prove it, and you'll do it consistently enough that developers start to recognize your name before they recognize the logo. You'll be part of the Developer Services team and work closely with Product, Engineering, Marketing, and Developer Support to turn technical capability into developer adoption. What You'll Do Create technical content that developers actually use Write blog posts, tutorials, and how-to guides that show real, working integrations — not just feature announcements Build a

About the Team OpenAI develops models that can reason through complex problems and hardware designed for the demands of advanced AI. AI for Chips connects these efforts: applying increasingly capable AI systems to the work of semiconductor engineering. Our goal is to help engineers develop better chips and shorten design cycles. This work brings research, model training, and hardware expertise together to build tools that engineers can use on real designs, with correctness and measurable performance at the center. About the Role We’re hiring a Research Engineer to help OpenAI models solve chip-design problems through reinforcement learning, tool use, and evaluation. You’ll own experiments from the initial idea through implementation and analysis. That means building environments and evaluations, running training, investigating failures, and using the results to decide what to try next. You’ll also build the software needed to make those experiments reliable and reproducible. We value strong coding fundamentals, careful experimental judgment, and the ability to make progress independently. Prior chip-design experience is helpful, but you can learn the domain alongside the team’s hardware specialists. In this role, you will: Build RL environments and evaluations for tasks such as RTL generation, design verification, and physical design optimization. Develop and test approaches that help models use chip-design tools and improve power, performance, and area while preserving correctness. Design experiments, establish baselines, and measure whether improvements hold up on new tasks and designs. Investigate failures across model behavior, rewards, evaluation tools, and experiment infrastructure. Improve iteration speed through better tooling, faster evaluations, and proxy rewards that reflect the outcomes we care about. Turn successful experiments into reusable research code and training workflows, working closely with researchers and engineers. You might thrive in this ro
