Company mission
Our mission is to open access to the world's culture through democratising language learning
Role
Who you are
- A deep understanding of both frontend and backend technologies and building with LLMs, with 5+ years of experience in using Typescript, React and Python to ship user-facing applications
- Experience building LLM-centred products
- Strong design sensibilities with the ability to translate them into intuitive and beautiful frontend user interfaces
- Strong software engineering experience with the ability to pragmatically think through software design and architecture to ship rapidly while scaling to hundreds of thousands of users
- You can ship at high velocity without compromising on quality and are comfortable figuring out how to build things you haven't built before
- Excellent communication and collaboration skills
Desirable
- Experience building in consumer
- Knowledge of WebRTC and frameworks to power real-time audio conversations (Pipecat, LiveKit, Daily etc.)
- Experience working with agentic frameworks such as Langchain to develop production-grade systems
What the job involves
- As a full stack engineer at Pendulum, you will work with our small but mighty team to develop intuitive user interfaces for voice-first interactions and contribute to the backend AI systems and infrastructure that supports these interactions
- Examples of recent full-stack work we have shipped include: handling real-time transcription over a WebRTC connection using Whisper models and streaming transcripts back to the frontend; developing a conversational voice AI system which can be interrupted by the user mid-speech; and giving our core conversational LLM agentic abilities to autonomously generate images based on conversational context
Application process

- 1-hour Technical interview
- 1-hour Call with whole team

Our take
Pendulum is an immersive language learning company, developing AI products that redefine the very basics of learning a new language. Pendulum develops its products off the philosophy that to truly learn a language, one must experience the culture, differentiating it from the gamified learning of Duolingo and the traditional focus of education on grammar and sentence memorising.
Its products leverage conversational voice AI and autonomous LLM agents to create evolving digital landscapes that are fluid to the customer's fluency level. Essentially, customers are immersed in open-ended scenarios that are actively shaped by their conversations, thus replicating the experience of speaking to someone in a foreign language
Founded by a small team emerging from the South Park Commons Founder Fellowship, Pendulum has garnered support from notable investors, including Shine Capital and Mercuri, and early backers from platforms like Notion, Vimeo, and Patreon. These endorsements reflect confidence in Pendulum's approach to learning new languages. The team behind Pendulum brings extensive experience in AI product development, having previously built solutions at Spotify, led product and strategy initiatives at Google, and conducted research on generative media and natural language processes at Oxford and Imperial College. With this extensive background, Pendulum is ready to transform the way we learn new languages.
