Job description

Who are we?

Cohere is the leading security-first enterprise AI company. We build cutting-edge foundation AI models and end-to-end products that are designed to solve real-world business problems.

We’re training and deploying frontier models for enterprises who are building AI systems. We believe that our work is instrumental to the widespread adoption of AI and we are looking for folks that want to be part of that.

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. Cohere is a team of researchers, engineers, designers, and more, who are all passionate about their craft.

We are a global technology company co-headquartered in Toronto and San Francisco, with key offices in London, New York City, Montreal, Seoul, Germany and Paris. Join us!

Why this role?

We're building the data infrastructure behind some of the most demanding AI training workloads in the world, and we want sharp, curious people to help us do it. In this role, you'll build and maintain the high-performance data layer our Modeling teams rely on for training and evaluation jobs.

As a Software Engineer, Data Infrastructure, you will:

• Work directly on petabyte-scale storage infrastructure, and the networking and performance challenges that come with it.

• Collaborate daily with researchers and engineers who are some of the best in the world at what they do.

You may be a good fit if you have:

• 4+ years of experience working on data storage infrastructure

• Strong command of Python

• Kubernetes experience, especially on the storage side (Persistent Volumes, CSI drivers, etc.)

• The ability to transform unstructured data into performant datasets across diverse storage backends including S3, GCS, and POSIX

• Experience with distributed data processing frameworks such as Apache Beam, Spark, or Flink

• [Nice-to-have] Familiarity with modern analytics tooling such as BigQuery, Airflow, or dbt

• Genuine excitement about AI. You follow the research, have opinions, and enjoy being in the weeds

• Comfort operating at the edge of what's known, with a desire to build something genuinely new rather than optimize what already exists

Full-Time Employees at Cohere enjoy these Perks:

• A weekly lunch stipend of $75/£75 or equivalent in your local currency for lunch.

• Full health and dental benefits, including a separate budget for mental health.

• RRSP matching, 401K, Pension Scheme.

• 100% Parental Leave top-up for up to 6 months, for either parent.

• Annual enrichment benefits:

  • Arts & culture, fitness/wellness, quality time, and a workspace improvement credit.
  • Education & learning stipend for conferences, courses, and coaching.

• 6 weeks of paid vacation (30 working days!)

• Budget for traveling to other offices if you are remote, plus an annual company offsite.

How and Where We Work:

• Cohere is remote-friendly. We have offices in Toronto, San Francisco, New York City, London, Paris, Montreal, and more coming soon.

• For those in the office: a daily lunch program, plenty of snacks, and regular community and social events.

• For those not near an office: a co-working benefit so you can work alongside others in your city.

• Everyone receives a $500 home office stipend to set up your workspace properly.

If any of the above doesn’t line up exactly with your experience, we still encourage you to apply.

We strive to create an inclusive work environment for all; we welcome applicants from all backgrounds and are committed to providing equal opportunities.
