Now they’re hiring a Senior Software Engineer to join a small, exceptional team building the future of online trust. About the Role As a Senior Software Engineer, you’ll be at the core of how our client builds and runs their platform; you won’t just be building features - You will help strengthen and evolve an already-live product, bringing structure and engineering judgment to an environment where foundations exist, but priorities and solutions are still being shaped as the company grows. * You’ll design and scale high-throughput APIs and microservices that power AI-driven fraud and bot detection engines. * You’ll work on production systems where latency, reliability, and real-world failure modes genuinely matter, and where engineering decisions have immediate customer impact. * You’ll work directly with founders, product, and research teams to deeply understand emerging threats, and build systems that turn detection insights into operational reality. * You’ll be encouraged to experiment, challenge convention, and proactively identify areas for improvement. NB: Please note, this role requires 3-4 days on-site in the office, ~ 5mins from Liverpool St Station. Required Skills * 3-5 Years of professional experience in software engineering. * Experience with TypeScript and/or Go is beneficial (but not mandatory) * Strong foundation in Kubernetes and CI/CD pipelines. * A resourceful, first-principles mindset; someone who thrives in ambiguity * Ownership, curiosity, and a commitment to building things that last * High-energy, thoughtful problem-solving, and a low-ego approach to collaboration * Experience in an early-stage start-up or scaling environment would be a huge bonus Pay range and compensation package * Competitive salary: £70,000 - £80,000 * Stock options – share in the company’s growth * Employer-matched pension Why Join this business If you want to work on a deeply meaningful problem, build with exceptionally talented engineers, and play a pivotal role in scaling a product that sits at the intersection of cybersecurity, AI, and internet infrastructure, this is the kind of opportunity that appears once in a career
