• Troubleshooting network and systems-level issues across trading infrastructure
• Enhancing observability with custom tooling and integrations
• Collaborating closely with infrastructure, DevOps, and engineering teams

Key Tech Stack

• Linux (CentOS/RHEL), Bash, Python
• Network protocols and analysis tools (tcpdump, Wireshark, Corvil)
• Kafka, Postgres (TimeScaleDB), ElasticSearch
• Time-series monitoring platforms: InfluxDB, Grafana, Kapacitor, Telegraf

What You’ll Get

• A key role in a fast-paced, technically advanced environment
• Autonomy to drive improvements in system performance and reliability
• Exposure to high-frequency, low-latency trading systems
• Hybrid working model with flexibility and occasional office visits
• Opportunity to collaborate with expert engineers in a performance-critical domain
