London, United Kingdom • Permanent • Full time • Competitive

The LSEG DevSecOps Engineering team inside the cyber security division is looking for Senior Software Engineers to build tools and automations to help secure software development for thousands of developers across the group.

Qualifications

• Deep understanding of cyber security principles, secure software development, and threat modeling
• Experience conducting security assessments, code reviews, and vulnerability management across diverse technology stacks
• Experience in building full-stack products (web applications, APIs, CI tooling or low-level software)
• Hands-on experience with cloud technologies (AWS, GCP, Azure) and containers (Docker, Kubernetes), with a focus on security
• Familiarity with infrastructure-as-code (Terraform, Pulumi, CloudFormation)
• Knowledge of supply chain security risks and mitigation strategies in the SDLC
• Ability to build and automate security tools, processes, and controls (e.g., web apps, APIs, CI/CD integrations)
• Strong communication skills for advising and educating engineers on secure coding and remediation
• Knowledge of common algorithms and data structures for dealing with large quantities of data (e.g., building data-intensive systems)
• Experience analysing large datasets for security monitoring, detection, or incident response

Additional context

As part of this role, you will get exposure to all parts of the business that build software using a wide array of technologies (low-level C++ to high-level TypeScript web apps to new cloud technologies). This is the ideal role for a polyglot technologist looking to make a large impact on securing software in the group. Note: You do not need all the skills listed above to qualify.
