About This Role

As a Senior Back End Engineer, you'll design and build low-latency, distributed systems for front-office trading, including OMS and matching engines. Your work directly supports high-volume trading operations, ensuring system scalability and resilience.

💡 A Day in the Life

You'll start by reviewing system performance metrics from overnight trading, then collaborate with traders on new feature requirements. Afternoon is dedicated to coding, code reviews, and testing, ensuring low-latency enhancements are deployed without disruption.

🎯 Who ICAP Energy AS Is Looking For

  • Proven experience building latency-sensitive trading systems (OMS, matching, execution) in a front-office environment.
  • Deep expertise in distributed, event-driven, cloud-native architectures with strong low-latency optimization skills.
  • Strong relational database design and performance tuning (MSSQL, MySQL) in high-volume contexts.
  • Hands-on leader who collaborates with architects and traders, owning deliverables end-to-end.

📝 Tips for Applying to ICAP Energy AS

1

Highlight specific trading system projects you've built or contributed to, emphasizing latency metrics and throughput improvements.

Quantify your experience with distributed systems and event-driven patterns, e.g., using Kafka or similar.

3

Showcase your database optimization work with real examples of schema design or query tuning for high-load scenarios.

4

Mention any familiarity with energy or commodities trading domains, even if tangential.

5

Tailor your CV to emphasize hands-on engineering leadership, not just management.
