• Design and build a low-latency, high-throughput data forwarding plane using Rust, leveraging its async/await model for efficient I/O and service-oriented infrastructure • Develop distributed, scalable systems with a focus on concurrency, fault tolerance, and messaging • Implement and maintain gRPC-based APIs and services to integrate forwarding plane capabilities with control and orchestration layers • Optimize system performance through profiling tools across kernel-space and user-space • Engage in code reviews, system design discussions, technical documentation, and mentoring junior engineers

• Write code for back-end processes, RESTful public web APIs, and, of course, our industry-leading website • Research technologies and engineer complete solutions to problems • Propose and implement performance optimizations and scaling strategies • Work with the rest of the team to integrate your projects into the application • Contribute to the ongoing improvement of our systems and processes • Integrate AI into your daily tasks using IDEs (or plugins) such as GitHub Copilot and Windsurf. Leverage ChatGPT to streamline your workload by brainstorming and refining ideas, and planning projects. • Mentor junior engineers and provide technical guidance. • Join our fast-paced team as we innovate at the speed of AI. AI is integrated into our products, development processes, and IDEs. We utilize AI tools like OpenAI, Claude Sonnet, and Gemini in our daily work.

• Design and implement APIs and backend services using Node.js (Express, Fastify, NestJS or equivalent frameworks). • Create and maintain integrations between internal and external systems via REST and/or GraphQL. • Model and optimize data structures, queries, and database access (SQL or NoSQL). • Implement authentication, authorization, security, and governance mechanisms (OAuth2, JWT, RBAC/ABAC). • Develop asynchronous processes, queues, workers, and caching strategies. • Build modular, responsive, and accessible interfaces using React (Hooks). • Create reusable components, UI patterns, and design systems. • Manage state (Redux, Zustand, Context API, React Query, etc.) with a focus on stability and performance. • Implement performance best practices: memoization, code splitting, lazy loading, and Suspense. • Participate in defining application architecture, evaluating technical trade-offs. • Ensure code quality, version control, code reviews, and engineering standards. • Conduct technical POCs/spikes to validate solutions and new technologies. • Collaborate with product, UX, and engineering teams on decisions and the technical roadmap.

Role Description This role sits within the CISO Advantage team, building a product that democratises access to enterprise grade cybersecurity leadership for organisations of all sizes. As a Software Engineer, you will contribute to designing, developing, testing, and maintaining high-quality software components. You will work closely with senior engineers, support product delivery, and continually build your technical skills while learning best practices in cloud native engineering, security, and scalable system development. What You Will Do - Contribute to the design and implementation of product features that align with technical strategy, quality standards, and functional requirements. - Develop clean, maintainable code along with corresponding automated tests. - Participate in release planning, providing reliable estimations and delivering work that meets scope and quality expectations. - Engage in code reviews and other collaborative engineering practices. - Take part in daily standups, sprint ceremonies, and retrospective discussions. - Participate in security reviews of new development to help ensure compliance with Sophos security requirements and industry best practices. - Troubleshoot and resolve issues, escalating complex problems to more senior team members when appropriate. Qualifications - Practical experience building backend services or APIs in a modern programming language (TypeScript preferred but not required). - Good understanding of API design, request/response lifecycles, and common integration patterns. - Experience writing clean, maintainable code accompanied by automated tests. - Awareness of secure coding practices, authentication/authorization concepts, and cloud native development. - Ability to debug production issues methodically and collaborate with senior engineers on complex problems. - Solid problem-solving, communication, and teamwork skills. - Experience using test automation frameworks (e.g. Mocha, Jest). - Bachelor’s degree in computer science, Software Engineering, or equivalent practical experience. Requirements - TypeScript backend development experience using Node.js/TypeScript for API or service layer development, understanding runtime considerations, type driven development, dependency injection, and module architecture. - Microservice architecture familiarity with distributed system concepts such as service boundaries, interservice communication, API gateways, observability, logging/metrics, configuration management, and handling failure modes gracefully (timeouts, retries, backoff, circuit breakers). - PostgreSQL (RDBMS) understanding of relational schema design, indexing strategies, query optimization, transactions, database migrations, and ORMs or query builders commonly used with TypeScript (Prisma, Drizzle, Knex). - Experience with containerized development workflows (Docker and Kubernetes), cloud platforms, or serverless components. - Knowledge of messaging systems or event-driven patterns is a plus. - Experience with automated testing and CI/CD pipelines. Benefits - Sophos operates a remote-first working model, making remote work the primary option for most employees. However, some roles may necessitate a hybrid approach. - Our people – we innovate and create, all of which are accompanied by a great sense of fun and team spirit. - Employee-led diversity and inclusion networks that build community and provide education and advocacy. - Annual charity and fundraising initiatives and volunteer days for employees to support local communities. - Global employee sustainability initiatives to reduce our environmental footprint. - Global fitness and trivia competitions to keep our bodies and minds sharp. - Global wellbeing days for employees to relax and recharge. - Monthly wellbeing webinars and training to support employee health and wellbeing.
