Lead Site Reliability Engineer - Algo-Trading (w/m/d)

As the technical lead for site reliability for our algorithmic trading and other key platforms, I own reliability, performance, and operational excellence end-to-end. I 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. My responsibilities include: - Defining and driving SLOs/SLIs, error budgets, and golden signals for latency-sensitive algo-trading services; leading incident response and postmortems with a blameless culture. - Designing and evolving geo-redundant, active-active/active-passive topologies across regions and availability zones, including failover, data replication, and disaster recovery (RTO/RPO). - Architecting, hardening, and operating AKS-based multi-cluster environments (multi-tenant, multi-region), including networking, security, autoscaling, node pools, and upgrade strategies. - Owning Terraform blueprints and Ansible automations for everything from base images to cluster add-ons, ensuring idempotent, policy-guarded, and auditable changes. - Building progressive delivery (blue/green, canary) pipelines with gated rollouts and automated rollback for trading microservices, adapters, market data, and execution gateways. - Implementing end-to-end tracing (OpenTelemetry), metrics, logs, and synthetic probes; leading capacity planning, performance tests, and p99/p999 latency optimization. - Enforcing runtime security, secrets management, image hygiene, and compliance controls integrated “shift-left” into build and deploy workflows. - Operating and optimizing Deltix-based components (Timebase DB, Ember, Strategy Server) in containerized, high-availability setups, and owning the corresponding Helm charts. - Mentoring SREs/DevOps/Developers, guiding design reviews, and aligning with Platform, Security, and Trading stakeholders on priorities and roadmaps. - Promoting a culture of innovation by staying up to date with new technologies and integrating useful advancements into the commercial area.
