Job Description

Office based in our Moorgate London premises, 4 days per week

Join Fortinet, a cybersecurity pioneer with over two decades of excellence, as we continue to shape the future of cybersecurity and redefine the intersection of networking and security. At Fortinet, our mission is to safeguard people, devices, and data everywhere. We are currently seeking a Software Engineer (Cybersecurity Analytics & Enforcement) to contribute to the success of our rapidly growing business.

The FortiDLP platform collects millions of data points per second, and innovative companies worldwide use FortiDLP for human-centric data loss protection. Our users need a way to spot trends in this data, search for security breaches, and take effective action. The Insight Team is responsible for the development and maintenance of our policy engine — a powerful framework used to detect cybersecurity violations through configurable rules and behavioral analytics. Our work spans the full lifecycle of these policies, including their creation, execution, and management.

As an Insight Team software engineer, your responsibilities will include:

• Designing and maintaining policies, which are configurable scripts written in Starlark(a Python-like embedded scripting language) that run on endpoints to detect signs of unauthorized or malicious activity.
• Continuously investigating new techniques to detect emerging forms of cybersecurity violations.
• Applying machine learning and statistical techniques to detect anomalies and identify suspicious or unexpected behavior.
• Researching and developing data identifiers (e.g. regular expressions) to detect sensitive information, and contributing to the underlying content extraction and identification infrastructure, including components written in C/C++/Swift.
• Enhancing and maintaining the execution environment for policies, built primarily in Go (Golang).
• Managing the policy lifecycle within our backendsystems, including APIs and infrastructure built in Go, using technologies like Protocol Buffers, PostgreSQL, and Elasticsearch.

We work on complex, cross-functional features that require close collaborationwith engineersacross the stack, product managers, technical writers, and support teams. Team members contribute throughout the development lifecycle — from writing technical specifications and coordinating implementation to demoingfeatures internally, supporting launches, and ensuring our solutions are well-documented and maintainable. We also work closely with the support and QA teams to prepare for releases, debug early issues in the field, and ensure a smooth rollout experience. High engineering standards are central to our team culture, including thorough code reviews, rigorous testing, and shared responsibility for quality and reliability.

We Are Looking For

Direct experience with our specific technologies is a bonus but not required. We’re looking for relevant experience with comparable tools and frameworks, and the ability to quickly learn and adapt. We encourage you to apply for this position if you have:

• A degree in Computer Science or a closely related field (Bachelor’s or higher), with a strong grasp of core computer science concepts such as memory management, concurrency, and backend development principles
• Strong programming skills, supported by several years of professional software engineering experience
• Experience with Java, C, C++, or similar languages, and an openness to learning Go
• Familiarity with Python, which shares syntax with Starlark(our embedded scripting language) and is commonly used to prototype models
• A strong interest or background in data science, machine learning, statistical analysis, or natural language processing is a plus — especially as applied to behavioral analytics and anomaly detection — but this is primarily a software engineering role, and we’re looking for engineers who are comfortable applying these techniques as part of a broader, hands‑on development role

We’re looking for engineers who communicate clearly, work well with a wide range of collaborators, and enjoy building shared understanding across disciplines. The role suits people who are thoughtful partners to product managers and support teams, value feedback as part of the development process, and bring a sense of ownership and care to both their code and their collaboration.
