Job description
Are you passionate about modern technology and eager to work in an agile, highly dynamic environment at the heart of the stock exchange trading business? Join our team that integrates and operates the low latency matching application within the trading platform. Your role will be to automate deployment, installation and integration of a third party developed matching application. In this position you will work closely across organizational boundaries with infrastructure, network, application and security teams.
Don't hesitate now and apply with your CV in English.
What You Will Do
- Automation of deployment, installation, configuration, and lifecycle upgrades of a third party matching application within the trading platform, using Ansible, GitLab, containerization and continuous integration practices.
- Operate and maintain the matching application in production and non prod environments, ensuring high availability, resilience, and security; build and improve CI and release processes in collaboration with infra and network teams.
- Integrate the application with surrounding platform components and services (databases, networks, monitoring, observability) and maintain operational documentation.
- Implement and manage monitoring and alerting (e.g. Grafana), support incident response and root cause analysis, and drive post incident improvements.
- Troubleshoot across the full stack-from low level network packet flows to OS, middleware, and application behavior-ensuring stable, compliant operations in a regulated environment.
Requirements
- Expert Linux skills with strong Bash scripting and Python programming for automation and tooling.
- Proven experience with DevOps practices and toolchains: Ansible, Docker, GitLab, Openshift and similar technologies.
- Solid networking knowledge (subnetting, firewalls, multicast, TLS) as well as IT security awareness (system hardening, secrets management, privileges).
- Familiarity with monitoring/observability (e.g. Grafana, Elastic) and orchestration tools (e.g. Airflow), as well as with SQL databases; advantage Dolt and QuestDB.
- Analytical mindset and excellent troubleshooting skills across layers; proactive, collaborative approach working with infrastructure, network, and application teams; readiness to support planned changes or incidents outside normal hours when needed.
- Very good verbal and written English.
