Who are we?
Our mission is to scale intelligence to serve humanity. We’re training and deploying frontier models for developers and enterprises who are building AI systems to power magical experiences like semantic search, RAG, and agents. We believe that our work is instrumental to the widespread adoption of AI.
We obsess over what we build. Each one of us is responsible for contributing to increasing the capabilities of our models and the value they drive for our customers. We like to work hard and move fast to do what’s best for our customers.
Cohere is a team of researchers, engineers, designers, and more, who are passionate about their craft. Each person is the one of the best in the world at what they do. We believe that a diverse range of perspectives is a requirement for building great products.
Join us on our mission and shape the future!
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 coding skills (Java, Javascript, Python, SQL) and algorithm knowledge 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 Full stack/Backend Developer - Data Annotators ensure that all samples fed to our AI model are well-written, technically sound and useful to the end user. By creating golden test sets, user testing and content that engineers would find useful, working in either Python, SQL, Javascript or Java. 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.
As a Data Annotator - Full Stack / Backend Developer, you will:
- Spend the majority of your time writing or reading/proofreading code and natural language to create perfect samples to train our models.
- Write prompt and code examples, along with unit tests to verify the accuracy of the code and model responses.
- Label, proofread, and improve machine-written and human-written code.
- Raise the bar continually by writing new code that is of exceptional quality to solve a variety of tasks.
- Adeptly vary the style, functionality of code examples.
- Follow our style guide, and make recommendations on unique situations that fall outside of its scope.
You might be a good fit if you are:
- 2+ years of industry experience working on real code in full stack or backend.
- Experience in any two of the following: Java, Javascript, Python or SQL.
- Experience with unit testing.
- A love for algorithms and competitive programming - you will be designing tricky prompts!
- A meticulous coder with an eye for readability.
- 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 Canada, the US, LATAM or UK timezones.
- 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.
