Advanced concepts (less common):

• Container orchestration with Kubernetes or Docker.
• Integrating automated security scanning into the deployment process.
• Developing custom providers for infrastructure automation tools.

Incident Management and Troubleshooting

When systems fail in the financial world, the stakes are measured in millions of dollars. Natixis values engineers who have a "cool head" and a systematic approach to incident resolution. You will be evaluated on your ability to perform root cause analysis (RCA) and implement preventative measures to ensure issues do not recur.

Be ready to go over:

• Log Analysis – Navigating complex log files across distributed systems to pinpoint failures.
• Network Troubleshooting – Understanding how DNS, load balancing, and firewall rules impact system connectivity.
• Disaster Recovery – The principles of failing over services to secondary sites and ensuring data consistency.

As a Systems Engineer at Natixis, your primary responsibility is the lifecycle management of the server infrastructure. This includes the initial design, provisioning, ongoing maintenance, and eventual decommissioning of hardware and virtual assets. You will be the guardian of system uptime, ensuring that the underlying platforms for the bank's services are always available and performing at peak efficiency.

Collaboration is a significant part of the day-to-day work. You will work closely with DevOps teams to bridge the gap between software development and infrastructure operations. You will also coordinate with Information Security to ensure all systems comply with global financial regulations and internal policies. This role often involves participating in an on-call rotation or handling escalations for critical production issues, requiring a high level of accountability.

Beyond maintenance, you will drive initiatives to modernize the stack. This might involve migrating on-premises workloads to a hybrid cloud model or implementing new monitoring solutions to gain better visibility into system health. You are expected to contribute to documentation and provide technical guidance to junior team members, fostering a culture of continuous improvement and knowledge sharing.

To be competitive for a Systems Engineer position at Natixis, you must possess a strong foundation in enterprise-level systems administration. The firm typically looks for candidates who have experience in high-availability environments where downtime is not an option.
