Senior Software Engineer | Start-up | Cybersecurity | London | Hybrid Hyre AI is partnering with a fast-growing, well-funded cybersecurity company on a mission to solve one of the biggest challenges on the modern internet: proving who's human in a world dominated by bots, scripts, and AI impersonators. Their technology protects some of the most trusted names in financial services and beyond, and they've just raised a multi-million seed round to accelerate growth. 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 build and run their platform; you won't just be building features - you'll be laying the technical foundation that allows them to verify humanity at internet scale. Design and scale high-throughput APIs and microservices that power AI-driven fraud and bot detection engines. Work on systems where latency and reliability are critical. Work directly with founders, product, and research teams to deeply understand emerging threats, and build systems that turn detection insights into operational reality. Be encouraged to experiment, challenge convention, and bring ideas that raise the bar. NB: Please note, this role requires 3-4 days on-site in the office, ~ 5 mins 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. #J-18808-Ljbffr
