Role Summary

At Sophos, our mission is clear: defeat cyberattacks and protect organizations around the world. We are seeking a Software Engineer to join our Security features team and help build the systems that make that mission possible.

In this role, you will work as part of a fast-paced, high-performing engineering team that designs, architects, and builds systems from the ground up. You’ll own the delivery of project work end-to-end — from understanding requirements, through design, implementation, testing, and deployment — and you’ll be responsible for the full lifecycle of the code you ship, including production support and continuous improvement.

This position is for an engineer who has a few years of professional experience under their belt and is ready to take ownership of meaningful work with moderate guidance. You’ll partner with senior engineers on more complex problems, mentor more junior teammates, serve as an on-call first responder for the services your team owns, and help raise the bar on quality and developer experience across the team.

We value curiosity, flexibility, and creative problem solving, and we’re committed to helping engineers continue to grow into senior technical leaders.

What You Will Do

• Design, develop, ship, and maintain features end-to-end in TypeScript across React frontends and backend services, with guidance from senior engineers on more complex initiatives.


• Own delivery of project-level work with moderate guidance — from breakdown and design through implementation, testing, deployment, and post-release iteration.


• Design and implement APIs that query, aggregate, and serve data reliably at scale.


• Build and operate cloud infrastructure using Infrastructure as Code (e.g., Terraform), following established team patterns.


• Serve as an on-call first responder for the services your team owns; triage, debug, and resolve production issues, then drive durable fixes and improvements.


• Create test plans for the features you build and contribute to automated testing (unit, integration, end-to-end) to enable safe, frequent releases.


• Conduct peer reviews of code, designs, test plans, and documentation, providing constructive feedback that raises team quality and adheres to engineering standards.


• Mentor IC1 engineers and interns; openly share expertise and knowledge within the team.


• Improve the developer experience by enhancing tooling, test coverage, and code structure (shift-left).


• Use modern AI coding tools to accelerate delivery while continuing to build the deep engineering foundations needed to grow into a senior engineer.


• Collaborate with Product Managers, UI designers, Cyber Analysts, and other engineers to deliver meaningful security outcomes for our customers.

What You Will Bring

• ~3+ years of professional software engineering experience shipping production systems (or equivalent demonstrable experience).


• Proficiency in TypeScript or JavaScript and a modern frontend framework (React preferred).


• Experience designing and building backend services and REST or GraphQL APIs.


• Solid grounding in computer science fundamentals: data structures, algorithms, software design, and debugging.


• Experience with relational and/or NoSQL databases, including basic schema design and query work.


• Experience writing automated tests (unit, integration, end-to-end) and giving high-signal code reviews.


• Ability to break down ambiguous problems, scope work, and reason through trade-offs with limited guidance.


• Track record of consistently delivering on time and to agreed quality.


• Clear written and verbal communication skills; comfort mentoring more junior engineers and sharing knowledge openly.


• Curiosity, continuous learning, and a strong sense of ownership over the code and systems you build.


• BSc in Computer Science or a related numerate discipline, or equivalent practical experience.

Desirable:

• Experience with cloud platforms (AWS preferred) and Infrastructure as Code (Terraform, CDK).


• Experience operating production services (on-call rotations, observability, incident response).


• Familiarity with CI/CD pipelines and modern delivery practices.


• Exposure to event-driven, distributed, or large-scale data systems.


• Interest or experience in cybersecurity.


• Experience using AI-assisted developer tools to improve productivity and learning velocity.

In Canada, the base salary for this role ranges from $95,000 to $159,000.  In addition to base salary, we offer additional compensation including bonus eligibility and a comprehensive benefits package.  A candidate’s specific pay within this range will depend on a variety of factors, including job- related skills, training, location, experience, relevant education, certifications, and other business and organizational needs.
