Senior Backend Software Engineer - CyberSec / Start-Up

About the Company:

Hyre AI is recruiting for a Senior Backend Engineer to join a highly ambitious early stage cybersecurity start-up at a crucial time in their growth following a successful seed round.

Our client is on a mission to make the internet a safer place; their products aim to make sure that behind every click, login, and purchase - is a real human being.

If you're a scrappy engineer who wants a role with autonomy & impact, this role might just be for you!

What you'll be doing:

In this role, you won’t just be building features — you’ll be laying the technical foundation that allows for the verification of humanity at internet scale. You will:

• Design and scale high-throughput APIs and microservices that power AI-driven fraud and bot detection engines.
  
  
• Architect backend systems where latency and reliability are critical — because in this domain, milliseconds and edge cases mean the difference between catching an attack or missing it.
  
  
• Work directly with founders, product, and research teams to deeply understand emerging threats — and build backend systems that turn detection insights into operational reality.
  
  Every architectural decision you make will be working towards a future where every internet interaction can be trusted.
  
  About you:
  
  Here’s the kind of person who our client would be excited to work with:
  
  
• You’re resourceful and fast-moving: You know how to navigate ambiguity and move projects forward without needing a playbook.
  
  
• You think from first principles: You break problems down to fundamentals, question assumptions, and build smart, original solutions when needed.
  
  
• You act with ownership: You take full responsibility for outcomes, not just tasks. You step into gaps, solve problems decisively, and keep standards high.
  
  
• You bring high energy and clear thinking: You approach challenges with curiosity, positivity, and focus — and you keep momentum even when things get hard.
  
  
• You care about the work, not the ego: You argue the case when it matters, back your thinking with evidence, and adapt quickly when new information comes in.
  
  
• You’re multi-dimensional: You're more than just your technical skills — you're intellectually curious, open-minded, and constantly sharpening your edge.
  
  Your experience:
  
  Here's some thoughts on the experience you'll need to be successful in this role:
  
  
• You’ve honed your skills over at least 4 years’ experience in backend development and have strong proficiency in GoLang and Node.js
  
  
• You’ve highly comfortable with DevOps principles; experience with Kubernetes would be a plus!
  
  
• Exposure to cloud platforms, particularly GCP or AWS
  
  
• Familiarity with other robust backend programming such as Python
  
  
• Experience on the front-end, particularly JavaScript would be a bonus!
  
  What's in it for you:
  
  
• Competitive salary (let’s talk!)
  
  
• Stock options – share in their growth
  
  
• Employer-matched pension plan
  
  
• The opportunity to shape systems that stop fraud before it starts and front-row seat in redefining online trust and identity
