Senior Software Engineer | Start-up | Cybersecurity | London | Hybrid

About the Company

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.

* You’ll design and scale high-throughput APIs and microservices that power AI-driven fraud and bot detection engines.

* You’ll work on systems where latency and reliability are critical.

* 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 bring ideas that raise the bar.

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
