Senior Golang Developer

What makes the role special

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 global 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.

YOUR MISSION

• Designing and implementing new product features and APIs;
• Building integrations with third-party data sources;
• Increasing the share of Golang services;
• Improving performance and scalability (query optimizations, sharding, etc.);
• Integrating services across the Group-IB product ecosystem;
• Developing and maintaining internal platforms used across teams.

WHAT WE ARE LOOKING FOR

• 5+ years of professional experience with Golang; other languages is a plus;
• Strong sense of ownership and a product mindset;
• Solid knowledge of SQL and experience with PostgreSQL or similar;
• Comfort working in Linux environments;
• Experience developing production-grade systems and APIs;
• English at upper-intermediate level or higher — we work in an international team and use English in documentation and daily communication.

WHAT SETS YOU APART

• Experience with Elasticsearch, Prometheus, Grafana, S3, or Cassandra;
• Experience with Redis or similar in-memory storage;
• Familiarity with message brokers (RabbitMQ, Kafka, NATS);
• Working on high-load or distributed systems;
• Observability skills (metrics, logs, alerts, traces).

WHY CHOOSE GROUP-IB

Group-IB is a global leader in cybersecurity technologies that investigate, predict, prevent, and fight digital crime. We help organizations reduce risk and protect trust. Trusted by governments, major industries, and law enforcement, we deliver adversary-focused, predictive threat intelligence and cyber fraud fusion solutions that detect, analyse, and mitigate regional and country-specific digital crimes.

• Work with real stakes. Group-IB investigates active cybercriminal groups, responds to breaches affecting critical infrastructure, and develops technologies used by law enforcement agencies including INTERPOL, Europol, and Afripol across 60+ countries. We've conducted 1,550+ cybercrime investigations alongside 600+ enterprise customers globally. When you join Group-IB, your work directly disrupts digital crime.
• Grow your way. Choose your own path: deepen your craft as a technical expert, step into leadership, move across to another team, or relocate to one of our Digital Crime Resistance Centers across the Americas, Europe, the Middle East & Africa, Central Asia, and the Asia-Pacific. Your growth is our growth — Group-IB's expansion across 60+ active country operations means real career acceleration.
• We fund professional certifications at company expense — whether you're pursuing CEH, CISSP, OSCP, or specialized certifications in forensics and penetration testing. You don't have to choose between doing the job and advancing your credentials.
• Work alongside industry leaders. Our Unified Risk Platform — Threat Intelligence, Digital Risk Protection, Attack Surface Management, Managed XDR, and more — is recognized by Gartner, Forrester, KuppingerCole, and Datos Insights. Frost & Sullivan named us a 2025 Global Technology Innovation Leader. When you work here, you're building technologies that set the industry standard.
• Real challenges, real expertise. You'll take on complex, real-world problems alongside adversary-centric researchers and incident response experts spread across six continents. We've built 21+ years of proprietary telemetry through 1,500+ joint investigations. No two threats look alike — and neither do the skills you'll develop.
• A team that is genuinely international. Our people come from different countries, speak different languages, and bring different perspectives. What connects us is a shared mission: fighting cybercrime and making the world safer. We care about your wellbeing and happiness as much as your output.
