ConnexAI is developing a transformative product that enables speech-to-speech capabilities in large language models. This is a greenfield project with significant scope to influence both its technical architecture and product impact from the ground up. We’re looking for a hands-on Machine Learning Engineer with deep expertise in building, optimising, and deploying ML systems — particularly in the areas of speech, LLMs, or multimodal learning. You will take cutting-edge research and turn it into production-ready models, enabling real-time, scalable, and reliable multimodal AI experiences.

What You'll Be Doing

  • Building and productising machine learning models for speech-to-text, text-to-speech, and speech-to-speech tasks

  • Translating academic and internal research into scalable, maintainable code and services

  • Developing and maintaining training pipelines, inference services, and deployment workflows

  • Implementing robust data pipelines for sourcing, preprocessing, and versioning multimodal datasets

  • Collaborating with research scientists to refine model architectures and integrate the latest techniques into production

  • Evaluating model performance with custom metrics and developing automated test frameworks for ML systems

  • Contributing to MLOps tooling and infrastructure to support model lifecycle management and monitoring in production

  • Working closely with product, research, and backend engineering to deliver seamless end-to-end features

What We're Looking For

  • Strong engineering background with experience shipping ML systems to production

  • Deep familiarity with speech technologies (ASR, TTS), LLMs, or multimodal machine learning

  • Proficient in Python, with expertise in ML frameworks such as PyTorch

  • Experience building scalable ML pipelines (training, validation, deployment, monitoring)

  • Knowledge of Docker, Kubernetes, and ML deployment platforms

  • Comfort reading and adapting recent research papers into performant implementations

  • Strong debugging and optimisation skills, particularly around model inference speed

  • Experience working in cross-functional teams and contributing to engineering culture and best practices

  • Bonus: experience with streaming audio processing, real-time systems, or speech synthesis engines

Why Join Us?

  • Be part of a foundational team building novel, multimodal AI capabilities

  • Shape the architecture and product direction from an early stage

  • Work in a fast-moving, collaborative environment with a strong focus on execution and innovation

  • Opportunity to grow alongside a rapidly scaling AI startup
