Founded in 2003 and headquartered in Singapore, Group‑IB is a leading creator of cybersecurity technologies to investigate, prevent, and fight digital crime. Combating cybercrime is in the company’s DNA, shaping its technological capabilities to defend businesses, citizens, and support law enforcement operations.

Group‑IB’s Digital Crime Resistance Centers (DCRCs) are located in the Middle East, Europe, Central Asia, and Asia‑Pacific to help critically analyze and promptly mitigate regional and country‑specific threats. These mission‑critical units help Group‑IB strengthen its contribution to general cybercrime prevention and continually expand its threat‑hunting capabilities.

About The Role At Group‑IB, we build high‑load backend services that power our products in fraud protection, threat intelligence, and digital risk prevention. Our engineering teams work on complex, data‑heavy systems that collect, process, and serve large volumes of data in real time to help customers prevent and investigate cyber incidents. We don’t believe in siloed responsibilities — developers own their features end‑to‑end: from clarifying requirements and writing code with tests to deploying it, monitoring performance, and maintaining it in production.



We’re looking for a strong backend engineer who enjoys solving engineering challenges at scale and is ready to take full ownership of their work.
