Salary: Competitive
ConnexAI is developing an ambitious new product to enhance our large language models with speech-to-speech capabilities. This greenfield project offers a unique opportunity to help define its research direction and build the machine learning systems that will power it. We’re seeking a data scientist with a strong research background in machine learning and a focus on speech or multimodal systems. In this role, you’ll work at the intersection of speech and language technologies, exploring how to integrate these modalities into deployable models. You’ll collaborate closely with engineers, researchers, and product leaders to design, prototype, and deploy state-of-the-art models.
What You'll Be Doing?
Researching the state-of-the-art approaches for incorporating audio data into multimodal LLMs for speech-to-text, text-to-speech, and speech-to-speech tasks
Implementing and adapting techniques from recent academic papers into practical, production-ready solutions
Training and fine-tuning models, and iterating on architectures to improve performance and scalability
Sourcing, curating, and preparing datasets for model training and evaluation
Defining evaluation metrics and testing frameworks for multimodal systems
Collaborating with product and engineering teams to translate research concepts into deployable features
Contributing to improving the team’s workflows to help foster a healthy, productive, and innovation-focused environment
What We're Looking For?
Background in machine learning or data science, ideally with a research focus (PhD or MSc with equivalent industry experience)
Experience working with LLMs, speech technologies (ASR, TTS), or multimodal systems
Strong programming skills in Python, with experience in using PyTorch
Hands-on experience with training and fine-tuning ML models, including setting up experiments and evaluating results
Ability to read, interpret, and implement techniques from recent academic papers into practical, working solutions
Strong communicator, comfortable working across interdisciplinary teams
A collaborative mindset and interest in helping improve team workflows
Curiosity and a willingness to learn
