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!

About North:

North is Cohere's cutting-edge AI workspace platform, designed to revolutionize the way enterprises utilize AI. It offers a secure and customizable environment, allowing companies to deploy AI while maintaining control over sensitive data. North integrates seamlessly with existing workflows, providing a trusted platform that connects AI agents with workplace tools and applications.

As a Senior Front-End Engineer you will:

  • Build and ship features for North, our AI workspace platform
  • Develop autonomous agents that talk to sensitive enterprise data
  • As security and privacy are paramount, you will sometimes need to re-invent the wheel, and won't be able to use the most popular libraries or tooling
  • Collaborate with researchers to productionize state-of-the-art models and techniques

You may be a good fit if:

  • Have shipped (lots of) frontend code (React) in production
  • You excel in fast-paced environments and can execute while priorities and objectives are a moving target
  • You've worked in both large enterprises and startups
  • You have strong coding abilities and are comfortable working across the stack.
  • You're able to read and understand, and even fix issues outside of the main code base
  • You have built and deployed extremely performant client-side or server-side RAG/agentic applications to millions of users.
  • Bonus: You love art and have an eye for design and a creative mindset - A plus, if you have a portfolio, GitHub or other showcases of your projects

If some of the above doesn't line up perfectly with your experience, we still encourage you to apply! If you want to work really hard on a glorious mission with teammates that want the same thing, Cohere is the place for you.

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.

Web Development Team Lead
Location: London (Hybrid)

Be the driving force behind the next generation of our property tech platform.

We’re looking for a hands-on technical leader who can balance writing code with leading a talented dev team . This isn’t about throwing everything away and starting fresh - it’s about smart evolution : scaling our platform, modernising where it matters, and keeping business needs front and centre.
You’ll own architecture decisions , speed up feature delivery, and take the weight off the CTO’s shoulders - all while helping your team level up.
 
What You’ll Do
Architect & Innovate
  • Review our existing PHP + Vue architecture and decide what stays, what goes, and what moves to Node/Next
  • Gradually introduce modular or microservice structures only when they add real value
  • Work with the CTO on strategy while confidently making your own calls
Code & Deliver (≈50% of your time)
  • Build and maintain in PHP/Vue for current services
  • Develop new features in Node/Next
  • Refactor, review, and maintain clean, consistent code
Lead & Develop People (≈50% of your time)
  • Mentor mid-level and senior developers, run 1:1s, and map their growth paths
  • Organise workflows, code reviews, and DevOps processes
  • Balance urgent tasks with strategic priorities, keeping delivery smooth
Bridge Tech & Business
  • Turn user pain points into smart, technical solutions
  • Partner with product managers to prioritise high-impact features
  • Release MVPs quickly, gather feedback, and iterate
Optimise DevOps
  • Improve CI/CD pipelines and Docker usage
  • Implement automated testing and service monitoring
  • Make deployments fast, reliable, and drama-free
  
 You’ll Succeed If You Have…
Must-Haves
  • 3–5+ years as a team lead, tech lead, or principal engineer
  • Hands-on Node.js & major frontend framework experience (React/Vue)
  • Proven ability to work with existing PHP codebases (Laravel/legacy)
  • CI/CD, basic Docker, automated testing know-how
  • Track record of building and developing teams (5–10 people)
  • Strong English communication skills (Upper-Intermediate+)
Nice-to-Haves
  • Kubernetes, Terraform, or advanced DevOps skills
  • Experience leading monolith → microservices transitions
  • Past CTO/startup founder perspective
  • Wider tech stack knowledge for creative problem solving
  
Why This Role Is a Game-Changer
  • Player-Coach Role – Half coding, half leading
  • Impact From Day One – Every decision you make shapes the platform’s future
  • Startup Agility – Move fast, avoid unnecessary bureaucracy
  • Career Growth – Scale your leadership scope as the product scales
  
 Apply now for this Web Development Team Lead role and take charge of architecture, build a high-performing dev team, and lead a platform transformation that impacts thousands of users.
