  • Communicate complex engineering concepts effectively to non-technical stakeholders

Requirements Essential Skills & Experience

  • Hands-on experience with monitoring and observability (Prometheus, Grafana, alerting frameworks)

Highly Advantageous

  • Experience with CI/CD systems such as FluxCD and GitHub Actions

  • Familiarity with DevOps practices and cloud-native automation

  • Background in trading, market-making, or high-frequency environments

  • Exposure to ultra-low-latency networking, performance tuning, and throughput optimisation
