Intuition Machines uses AI/ML to build enterprise security products like our hCaptcha security suite. We apply our research to systems that serve hundreds of millions of people, with a team distributed around the world. Our approach is simple: low overhead, small teams, and rapid iteration.

As a Senior Backend Engineer you will be responsible for work on core production code that can include distributed systems work and implementing or optimizing machine learning paths. You will improve and drive our evolving systems, threat models, and CI/CD practice.

Using AI: Coding agents are indisputably useful tools. We provide access to the top 3 models, and were early adopters of evals-first development flows. Familiarity with coding using agents is part of all interviews. However, reliability and correctness are critical for us. You will need to read and understand every line of code with your name on it, and it will be reviewed by both people and machines.

What you will do:

• Design, build and maintain secure, scalable backend services and algorithms
• Implement DevSecOps practices: security protocols, monitoring, metrics, and automated alerts

• An inspiring team of colleagues spread all over the world.
• Pleasant, modern development and deployment workflows: ship early, ship often.
• High impact: lots of users, happy customers, high growth, and cutting edge R&D.
• Flat organization, direct interaction with customer teams.

We celebrate equality of opportunity and are committed to creating an inclusive environment for all team members. Join us as we transform cybersecurity, user privacy, and machine learning online!

Please note that all positions require pre-employment screening, including third-party verification of work history, education, and identity, as well as a final in-person interview and identity verification step, which will be conducted in your country of residence.
