Senior Backend Engineer

About Intercepta

Intercepta builds real-time security infrastructure that operates inside transaction flows — detecting risk, simulating intent, and preventing attacks before execution.

Role Overview

As a Senior Backend Engineer, you will design and scale systems that process onchain data, generate risk signals, and power mission-critical protection for wallets, exchanges, and fintech platforms.

Your Impact

• Design and build low-latency backend systems for real-time threat detection
• Develop services that analyze and simulate transaction behavior before execution
• Work with high-volume blockchain data and streaming pipelines
• Build and optimize data processing systems for reliability, throughput, and speed
• Collaborate with data and security teams to productionize detection logic
• Contribute to system architecture, scalability, and infrastructure decisions
• Own systems end-to-end — from design to deployment and monitoring

Requirements

• 5+ years of backend engineering experience building and scaling complex systems
• Strong proficiency in Python, Go, or Rust
• Experience with distributed systems and high-load environments
• Deep understanding of EVM internals, transaction lifecycle, and blockchain node architecture (RPC, mempool, execution layer)
• Experience with real-time or streaming systems (Kafka, Flink, Spark, etc.)
• Strong understanding of data systems (SQL/NoSQL, data pipelines, storage)
• Experience with cloud infrastructure (AWS/GCP), containers, and CI/CD
• Strong system design and problem-solving skills
