Your responsibilities
Position Summary:
You will be the technical lead for site reliability for our algorithmic trading and other key platforms—owning reliability, performance, and operational excellence end-to-end. You’ll set the technical direction, drive standards, mentor engineers, and partner with quants, traders, development, and other teams to deliver geo-redundant, containerized, and compliant trading systems with near-zero downtime.
Your Responsibilities:
* Reliability ownership: Define and drive SLOs/SLIs, error budgets, and golden signals for latency-sensitive algo-trading services; lead incident response and postmortems with a blameless culture.
* Production architecture: Design and evolve geo-redundant, active-active/active-passive topologies across regions and availability zones, including failover, data replication, and disaster recovery (RTO/RPO).
* Kubernetes at scale: Architect, harden, and operate AKS-based multi-cluster environments (multi-tenant, multi-region), including networking, security, autoscaling, node pools, and upgrade strategies.
* Infrastructure as Code: Own Terraform blueprints and Ansible automations for everything from base images to cluster add-ons, ensuring idempotent, policy-guarded, and auditable changes.
* Automation & Efficiency: Build progressive delivery pipelines with gated rollouts and automated rollback for trading microservices, adapters, market data, and execution gateways.
* Observability & performance: Implement end-to-end tracing (OpenTelemetry), metrics, logs, and synthetic probes; lead capacity planning, perf tests, and p99/p999 latency optimization.
* Runtime safety: Enforce runtime security, secrets management, image hygiene, and compliance controls integrated into build and deploy workflows.
* Algo-trading runtime: Operate and optimize Deltix-based components (Timebase DB, Ember, Strategy Server) in containerized, high-availability setups. Own the corresponding Helm charts.
* Collaboration & leadership: Mentor SREs/DevOps/Developers, guide design reviews, and align with Platform, Security, and Trading stakeholders on priorities and roadmaps.
* Innovation: Promote a culture of innovation by staying up to date with new technologies and integrating useful advancements into the commercial area.
