Why This Job is Featured on The SaaS Jobs
This Senior Software Engineer role sits at the intersection of SaaS product engineering and enterprise-grade security, focused on an AI workspace platform where agents interact with sensitive customer data. In the current SaaS landscape, that combination is increasingly central as AI features move from experimentation into production environments that must meet strict trust, privacy, and deployment expectations.
For a SaaS career, the standout value is experience building security features that are directly user facing, rather than treating security as a separate function. Work that spans authentication patterns, secure session handling, privacy constraints, and application security testing maps well to modern SaaS roadmaps, where compliance and risk management shape product decisions. The emphasis on writing minimal, deployable code under constraints also develops engineering judgment that transfers across multi-tenant platforms and regulated customer segments.
This position tends to suit engineers who enjoy owning security outcomes end to end, from design through verification, and who are comfortable operating across the stack when needed. It also aligns with professionals who like pragmatic problem solving, including occasional reinvention when common libraries are not viable, and who want their work to influence how AI capabilities are safely delivered to enterprise users.

Why This Role?
Are you passionate about secure-by-design software engineering? Do you want to be at the forefront of AI innovation and enterprise security? Cohere's North team is seeking a Senior Software Engineer with a focus on security to join our mission and make a significant impact.
Your Role:
As a Senior Software Engineer with a security focus, you'll play a pivotal role in building and securing North's architecture. Your responsibilities will include:
Build and ship security features for North, our AI workspace platform
Develop autonomous agents that talk to sensitive enterprise data
Write and ship minimal code that runs in low-resource environments, and has highly stringent deployment mechanisms
Pulling in new tools to enhance North's security capabilities
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
Perform application security testing for your code to test its resilience against real-world threats
You may be a good fit if:
5+ years previous experience in software engineering with a strong focus on developing user facing security features
You have strong development skills, and have shipped (lots of) Python in production
You have a solid knowledge of security principles like session management, multi-factor authentication, and secure coding practices
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 employ a flexible and constructive approach when solving problems
You excel in fast-paced environments and can execute while priorities and objectives are a moving target
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.
