Create and Share Performance Playbooks (by Day 45) Build SOPs for slow query debugging, frontend perf checks, Redis TTL fixes, or Node.js memory leaks. Turn performance tuning into team sport. Guide Teams on Performance-Aware Development (within 90 days) Create internal micro-trainings or async reviews to help devs write faster APIs, reduce DB load, and spot regressions earlier. Use AI or Smart Tooling in Diagnostics Try out tools like Copilot for test coverage, or use AI-powered observability tools (e.g. Datadog AI, Loki queries, etc.) to accelerate diagnostics. Build Flamegraph/Profiling Baselines Set up and maintain performance profiling baselines (using Clinic.js, 0x, etc.) so regressions can be caught before they ship. Review Queues and Caching Layer Identify performance issues in Redis queues — retries, TTL delays, locking — and tune caching strategies across app and DB. Contribute to Performance Culture Encourage tracking of real metrics: TTI, DB query time, API P95s. Collaborate with product and engineering to define what “fast enough” means. Experience Level: 3–5 years Tech Stack: Node.js, MySQL, Redis, Grafana, Prometheus, Clinic.js, Percona Toolkit Culture Fit – Are You One of Us?

Collaborate with trading and engineering teams to deploy and monitor high-performance market data and order execution pipelines. Build observability systems that don’t just monitor — they help predict and prevent latency degradation. Stay current on the evolving cloud exchange landscape and proactively adapt systems to maintain a competitive edge. The Skills and Qualifications Deep experience with AWS networking, compute, and systems internals — EC2, ENA, placement groups, Nitro, latency tuning. Strong grasp of Linux performance tuning, networking (TCP/UDP, DNS, BGP), and low-level debugging tools (e.g., perf, tcpdump, strace). Hands-on experience optimizing for low latency in a trading, gaming, or real-time systems environment. Comfortable with infrastructure automation — Terraform, Ansible, or similar. Experience building and maintaining CI/CD workflows and monitoring infrastructure. Programming proficiency for infrastructure tooling (Python preferred). Bonus: Familiarity with Rust or C++ in performance-critical systems. Bonus: Exposure to crypto exchanges, market data APIs, or cloud-based trading infra.
