Data Annotator/AI Data Trainer - Data Scientist (Contractor)



Software Engineering, IT, Data Science
London, UK

Who are we?
Cohere is focused on building and deploying large language model (LLM) AI into enterprises in a safe and responsible way that drives human productivity, and creates magical new ways to interact with technology and real business value. We’re a team of highly motivated and experienced engineers, innovators, and disruptors looking to change the face of technology.
Our goals are ambitious, but also concrete and practical. Cohere wants to fundamentally change how businesses operate, making everyone more productive and able to focus on doing better what they do best. Every day, our team breaks new ground, as we build transformational AI technology and products for enterprise and developers to harness the power of LLMs.
Cohere was founded by three global leaders in AI development, including our CEO, Aidan Gomez, who co-created the Transformer, which makes LLMs possible. Collectively, we're driven by the belief that our technology has the potential to revolutionize the way enterprises, their employees, and customers engage with technology through language.
Cohere’s broader research team is world-renowned, having contributed to the development of sentence transformers for semantic search, dynamic adversarial data collection and red teaming, and retrieval augmented generation, often referred to as “RAG,” among other technological breakthroughs.
We have been deliberate in assembling a team of operational leaders with industry-leading experience, with backgrounds working at the most sophisticated, demanding, and respected enterprises in the world. Cohere’s operational leaders have built, scaled, and led multi-billion product lines and businesses at Google, Apple, Rakuten, YouTube, AWS, and Cisco.
The Cohere team is a collective from all walks of life, from people who left college to start businesses, to some of the most experienced people from globally renowned companies. We believe a diverse team is the key to a safer, more responsible technology, and that different experiences and backgrounds enable us to tackle problems from all angles and avoid blindspots.
There’s no better time to play a role in defining the future of AI, and its impact on the world.
Why this role?
At Cohere, we’re obsessed with language and technology— we believe we need great writers and developers and always will. We also believe that remarkable talent, enthusiasm, and creative thinking add up to great work. We’re looking for someone with superb python and data science skills to join our team and help shape the future of language technology. The most successful candidate will be a quick learner who is excited to train our model by working on a wide variety of writing and code based prompts.
We are on a mission to build machines that understand the world and make them safely accessible to all. Data quality is foundational to this process. Machines (or Large Language Models to be exact) learn in similar ways to humans - by way of feedback.
Our AI Data Trainers ensure that all samples fed to our AI model are well-written, technically sound and useful to the end user. By creating content that data scientists would find useful, working python, or on use cases you will be an essential component of improving our Large Language Model’s performance for iterations to come, thus having a lasting impact on Cohere’s tech.
Please Note: This is role may require occasional work on-site at our Soho office in London, UK. We are looking for candidates who are able to commit 12-24 hours a week minimum to this project.

  • Able to use sql syntax writing and workflows
  • You have good familiarity with file/data formats, such as markdown, json, xml, yaml, html
  • A thoughtful and thorough code reviewer. You've spent time re-writing, proofreading, and giving feedback on others' code in a previous role. You've worked with a code style guide before and enjoyed it

Other things you’ll need:

  • Located in the UK
  • A fast, thorough reader with great comprehension skills
  • A curiosity about ML or AI or LLMs, (bonus points if you have any experience in these)
  • Expert in web-based research skills that you've used for your code before
  • Ability to follow complex instructions, navigate ambiguity and work independently in a remote or hybrid environment
