Why This Job is Featured on The SaaS Jobs
Research Engineer roles are increasingly central in SaaS as AI capabilities move from prototypes into paid, developer-facing products. This listing stands out because it sits at the point where model research, platform engineering, and customer use cases intersect, supporting systems like semantic search, RAG, and agents that are becoming common building blocks across modern SaaS.
For a SaaS career, the durable value here is learning how frontier ML work becomes reliable software: experiment design, evaluation discipline, and the infrastructure choices that determine cost, latency, and iteration speed. Working alongside researchers while owning practical implementation builds an instinct for turning ambiguous ideas into deployable components, a skill that translates to applied AI teams across B2B SaaS, platform companies, and internal ML enablement groups.
This role fits engineers who prefer hands-on problem solving over purely theoretical work, and who enjoy moving between code quality, debugging, and empirical results. It also suits someone who wants a research-adjacent path without stepping away from engineering fundamentals, and who is motivated by building shared tools and pipelines that others can extend.
The section above is editorial commentary from The SaaS Jobs, provided to help SaaS professionals understand the role in a broader industry context.
Job Description
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 content generation, 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 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!
Cohere Labs is the dedicated research arm of Cohere. Our mission is to push machine learning forward through open, collaborative research and hands-on experimentation. We work on frontier problems in NLP and AI while creating space for researchers and engineers from different backgrounds to contribute, learn, and grow.
We care about building things that are both thoughtful and useful, from new methods and datasets to tools that make research more accessible. Our team values curiosity, ownership, and practical impact over hype.
Why join Cohere Labs?
Cohere Labs brings together researchers and engineers to explore ambitious ideas and turn them into real systems. We focus on advancing machine learning while expanding access to applied research training and global collaboration.
We pursue this mission in two ways:
Creating open, collaborative research spaces where engineers and researchers work side-by-side on ambitious ML problems.
Expanding access to applied research training, helping early-career engineers grow into strong research contributors.
About the role
We’re looking for Research Engineers who enjoy getting their hands dirty: building experiments, debugging models, scaling training pipelines, and turning research ideas into working systems.
This is a highly practical role. You’ll work closely with scientists and other engineers to implement new methods, run large-scale experiments, and help shape the infrastructure that supports our research programs.
You don’t need to have everything figured out yet. We care more about curiosity, strong fundamentals, and a willingness to learn quickly in a fast-moving research environment.
You may be a fit if you:
Have a strong engineering background in machine learning, NLP, or related areas (through a Master’s degree, industry experience, or equivalent hands-on work).
Enjoy writing clean, reliable code and building systems that others can use and extend.
Are comfortable experimenting, running ablations, analyzing results, and iterating quickly.
Have experience with deep learning frameworks and model optimization techniques (PyTorch, distributed training, RLHF, finetuning, evaluation frameworks)
Like collaborating closely with researchers and translating ideas into practical implementations.
Are excited to grow your research instincts while staying grounded in engineering excellence.
At Cohere Labs, research engineers are not just support roles. They are core contributors who help define how ideas become reality. If you want to work on meaningful problems, learn fast, and help build tools that shape the future of AI, we’d love to hear from you.
If some of the above doesn’t line up perfectly with your experience, we still encourage you to apply!
We value and celebrate diversity and strive to create an inclusive work environment for all. We welcome applicants from all backgrounds and are committed to providing equal opportunities. Should you require any accommodations during the recruitment process, please submit an Accommodations Request Form, and we will work together to meet your needs.
