Requirements
  • Experience as a machine learning engineer with broad knowledge and skills in natural language processing.
  • Experience building backend systems and working across a code base, not just in Jupyter notebooks.
  • Proficiency in Python.
  • Ability to work independently to handle ambiguity.
  • Detail-oriented when it matters and able to balance speed and perfection in a fast-moving startup environment.
  • Knowledge of pitfalls and tricks for building with large language models, especially retrieval-augmented generation systems.
  • Excited about the opportunity to tackle impossible problems.
  • Willing to compromise on years of experience for the right candidate.
Responsibilities
  • Fine-tuning models to boost conversational quality and scalability.
  • Owning new ideas for engaging features and taking them from concept to production across the stack.
  • Identifying novel ways to build a memory to create personalized user experience.
  • Leading technical decision making to find innovative and practical solutions.
  • Optimizing infrastructure for performance, scalability, and reliability.
  • Ensuring rigorous testing, validation, and continuous improvement of deployed models.

Continua brings the power of large language models into group chats, acting as a quiet, helpful member within conversations rather than a dominant interface. The product works by integrating AI into group chats to participate, summarize, and contribute ideas in real time, while keeping the human dialogue at the center. Unlike tools designed for single-user interactions, Continua focuses on a multiplayer, collaborative chat experience—where the AI fades into the background as a shared layer of intelligence—so discussions stay natural and social. The company emphasizes a social, background role for AI and aims to enhance relationships, not replace them, with leadership from David Petrou and backing from notable investors. Ultimately, Continua’s goal is to make technology disappear into the background and strengthen human connections through group conversation.
