Original 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 headquartered in Toronto with key offices in London, New York City, San Francisco, Montreal, Paris, Berlin and Seoul. Join us!

ABOUT THE ROLE

We're seeking a Senior/Staff Engineer to build and maintain the automation infrastructure that powers the development cycles of our North platform. This engineer will design and implement robust automation systems that enable engineers to efficiently test and validate changes across diverse environments and configurations. This role sits at the intersection of infrastructure and standards. You'll build the systems, frameworks, and culture that allow the rest of engineering to own quality themselves; improving and extending our testing platform by creating the infrastructure that allows engineers to write and execute tests, and enable every engineering team to ship with more confidence.

KEY RESPONSIBILITIES

Design and implement automation pipelines that support comprehensive testing across multiple environments with varying feature flags and realistic customer data profiles
Create intelligent testing agents that simulate real user behavior to validate different configuration combinations
Develop and maintain GitHub workflows and actions to automate testing, deployment, and validation processes
Manage and optimize Helm charts for deployment consistency across environments
Implement and maintain ArgoCD workflows for continuous deployment and environment management
Establish best practices for testing methodologies and ensure adoption across engineering teams
Build scalable infrastructure that supports parallel test execution across diverse configurations
Develop infrastructure-as-code templates and configurations for reproducible test environments
Implement containerization strategies for test environments and dependencies
Create benchmarking frameworks to measure performance and reliability across different configurations
Monitor and improve test coverage and reliability metrics
Collaborate with product and engineering teams to understand testing requirements and translate them into automated solutions
Troubleshoot and resolve complex testing infrastructure issues

REQUIRED QUALIFICATIONS

5+ years of software engineering experience with a focus on automation and testing infrastructure
Expert proficiency in Python and TypeScript
Extensive experience with GitHub workflows and actions
Deep understanding of testing methodologies and best practices
Experience building and maintaining CI/CD pipelines
Containerization experience (Docker, Kubernetes)
Benchmarking experience and performance testing methodologies
Cloud platform experience (AWS, GCP, or Azure)
Background in developer tools or platform engineering
Ability to design and implement complex automation systems
Strong problem-solving skills and attention to detail

PREFERRED QUALIFICATIONS

Experience working with LLMs in production environments
Familiarity with infrastructure-as-code principles
Experience with container orchestration and management
Knowledge of performance testing tools and frameworks
Experience with monitoring and observability tools
Background in test framework development
Strong working knowledge of Helm charts and ArgoCD
Infrastructure-as-code experience (Terraform, Pulumi, or similar)

WHAT YOU'LL BUILD

You'll enhance our testing platform to allow engineers to:

Spin up environments with specific feature flag combinations using infrastructure-as-code
Load test configurations with realistic customer data volumes in containerized environments
Run comprehensive test suites across multiple environment configurations with automated benchmarking
Generate detailed performance and reliability reports across different cloud environments
Automatically detect and flag regressions in diverse usage scenarios
Scale testing infrastructure to accommodate our growing customer base

This is a critical role for ensuring the reliability and scalability of our North platform as we continue to grow our customer base and expand our feature set. You'll have the opportunity to shape the future of our development infrastructure and make a significant impact on product quality. (edited)
