Role Summary
At Sophos, our mission is clear: defeat cyberattacks and protect organizations around the world. We are seeking a Junior 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 work on real production code that protects customers at scale and gain hands-on experience throughout the software development lifecycle - from understanding requirements, to implementing, testing, and deploying out new features.
This position is for someone early in their career, who is excited to learn by doing. As a Junior Software Engineer, we will guide you through breaking down complex problems and translating their solutions into clean, production-ready code. As you grow, you’ll develop strong systems-level thinking and gain confidence debugging issues, improving existing systems, and building new services from scratch.
Overall, we value curiosity, flexibility, and creative problem solving, and are committed to helping new hires build the foundations they need to grow into strong software engineers.
What You Will Do
- Write code, primarily in TypeScript, across the full stack of both frontend (e.g., React) and backend services.
- Design and implement APIs to query, aggregate, and serve data reliably at scale.
- Debug production issues and improve system performance, reliability, and code quality.
- Learn the fundamentals of building cloud infrastructure using Infrastructure as Code (e.g., Terraform).
- Participate in research, prototype and evaluate solutions, making thoughtful technical trade-offs.
- Contribute to code reviews and automated testing to enable safe, frequent releases.
- Use the latest AI coding tools to help you learn faster and accelerate delivery, while building the deep engineering foundations to become an expert in your own right. Collaborate with experienced engineers, Product Managers, UI designers, and Cyber Analysts to solve meaningful security problems.
What You Will Bring
- Essential:
- BSc in Computer Science or a related numerate discipline, or equivalent practical experience.
- Experience with TypeScript or javascript.
- Strong foundations in computer science fundamentals (e.g., data structures, algorithms, software design, and debugging).
- Experience writing your own code through academic projects, internships, personal projects, or open-source contributions.
- Ability to break down ambiguous problems and reason through trade-offs.
- Clear written and verbal communication skills.
- Curiosity, continuous learning, and a willingness to take ownership.
- Desirable:
- Familiarity with frontend development (e.g., React or Angular).
- Familiarity with backend development and writing API endpoints.
- Understanding of relational and/or NoSQL databases.
- Exposure to automated testing (unit, integration, or end-to-end).
- Familiarity with REST APIs or GraphQL.
- Interest in cybersecurity and distributed systems.
In Canada, the base salary for this role ranges from $67,000 to $111,000. 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.
