Software Engineer

• 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
• 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
