Respeecher is a pioneer in the area of AI-generated voices. In 2019, our voices were the first to be used in a Hollywood movie, and in 2025 we gave AI superpowers to the main characters of the Oscar-winning movies The Brutalist and Emilia Pérez.
Our AI research team has developed a panoply of models and training and inference techniques that are expertly deployed by our delivery team, which has worked on 200+ projects in dozens of languages across almost every sector of the media and entertainment industry.
This year, we’re expanding beyond M&E, starting with the launch of our real-time text-to-speech API for voice chatbots.
About the role
We’re looking for a Backend Engineer to help us build and scale our real-time TTS API. While the initial version is about to launch, we’re just getting started — and there’s a long list of interesting and challenging problems ahead. You’ll join a small team with a founder mindset and a deep care for developer experience and customer success.
We may have been pioneers in AI voices, but we’re now competing in a fast-moving space. To win, we’ll need to deliver a world-class product, with performance, reliability, and user experience at its core.
We mostly work in Python but reach for other tools when needed.
What you might work on
Depending on your strengths and the needs of the product, you could dive into: * Integration with model-serving engines (vLLM or SGLang) * Serving multi-model deployments in Kubernetes with Ray Serve * Observability using SaaS products like VictoriaMetrics and open-source tools * In-house systems for testing model output quality — fully automated and human-in-the-loop * FastAPI-based client-facing APIs, backed by Postgres * SDKs and docs powered by Fern * Analytics to guide product iteration * Talking to customers — we hope you will enjoy communicating with the people we are building all this stuff for!
What we’re looking for * Designed and build APIs before — whether at work or in side projects * Can work efficiently in Python * Comfortable working in a low-structure environment with lots of unknowns * A scientist’s curiosity when debugging performance and reliability issues * Strong focus on building clean, understandable systems * Passion for DX and developer-first APIs * A habit of keeping up with emerging tools and tech — and knowing what’s useful vs hype * Strong opinions, loosely held * Clear communication in English
Why you should join us * Make an impact from day one — you’ll work directly with founders and product leads * Help shape a new product and a new market for Respeecher * Own your work — vision, execution, and iteration * Work in a collaborative, learning-focused environment
Benefits * Unlimited vacation policy * Office in central Kyiv and freedom to work from the office or remotely * Amazing colleagues who love what they do and helping each other out!
