Senior DevOps Engineer (Trading Platform)

Job description

The Trading Infrastructure team is building a high-performance, front-to-back Trading Platform that supports multi-asset trading. The platform is designed to handle financial instruments with low-latency execution, robust risk controls, and seamless integration across trading, risk, operations, and finance workflows. The system is built with a modular architecture encompassing core components such as market data feeds, order gateways, execution algorithms, risk engines, UI dashboards, middle office reconciliation, and account infrastructure. We emphasize event-driven, deterministic system design, real-time observability, and strong security. Our tech stack includes Java (low-latency), Python, Web UI (React/Ag-Grid), Aeron, ClickHouse, Kubernetes, and modern CI/CD tooling, with a strong focus on automation, scalability, and performance. AI-assisted development tools are also leveraged to boost productivity and quality across the team. ### Responsibilities - Design, provision, and maintain scalable infrastructure for our trading systems, including CI/CD pipelines, observability stack, and runtime environments. - Administer and tune databases such as AWS Aurora, PostgreSQL, and ClickHouse. - Automate provisioning and configuration of EC2 and related resources using Ansible and other infrastructure-as-code tools (e.g., Terraform). - Ensure secure, stable environments through proper VPC design, IAM governance, and secret management. - Build and maintain system metrics and alerts using Prometheus, Grafana, and Loki. - Enforce GitHub repo and branching standards across development teams. - Ensure cost-effective infrastructure usage through continuous monitoring, resource optimization, and cost control strategies across AWS and containerized deployments. - Manage backup and disaster recovery procedures for all critical systems. - Collaborate with engineering teams to containerize services and fine-tune runtime performance. - Evaluate and integrate AI/LLM tools to improve automation, diagnostics, and operational efficiency. ### Requirements - 5+ years of DevOps or SRE experience in high-availability, real-time systems. - Strong hands-on experience with AWS services (EC2, VPC, IAM, CloudWatch, RDS) and cost monitoring tools (e.g., AWS Budgets, Cost Explorer). - Skilled in provisioning and config management using Ansible; Terraform experience is a plus. - Proficient in ClickHouse and PostgreSQL; knowledge of kdb+ or InfluxDB is a bonus. - Solid scripting skills (Python, Bash, or equivalent). - Hands-on experience with Docker, Kubernetes, Helm, and deployment automation. - Familiar with monitoring and logging stacks; experience with Prometheus/Grafana is expected. - Security-conscious and experienced in IAM, encryption, and secure system design. - Able to monitor and optimize computing resources to maintain performance within budget constraints. - Comfortable using AI tools for automation, diagnostics, or efficiency gains. ### Communication & Collaboration - Proficient in English (spoken and written); Chinese or other languages are a plus but not required. - Comfortable working in a global team with colleagues across APAC, EMEA, and North America. - Strong communication skills; able to interface across all levels from senior leadership to engineers and cross-functional stakeholders. - Able to explain complex systems to both technical and non-technical audiences and coordinate effectively across teams with diverse backgrounds.
