Site Reliability Engineer (m/f). Luxemburgo

Your role – Are you ready for a challenge?

The Site Reliability Engineer is mission-driven: has experience with a set of engineering practices for running safe and reliable production systems - design for operability and security, and working with a breadth of tools and approaches to solve a broad spectrum of problems.

SRE has the responsibility of building, running and maintaining the platform on which LIA is relying. This means a strong involvement in incidents/problem resolution.

Core responsibilities:

    Incident response and resolution: when incidents occur, you are responsible for responding promptly, diagnosing the problem, debugging, and implementing appropriate solutions to minimize downtime and restore services;

    Collaboration with cross-functional teams: work closely with other teams, to understand their requirements, provide support, and ensure smooth operations of the whole platform;

    Documentation and knowledge sharing: maintaining accurate documentation of configurations, troubleshooting procedures, and best practices is crucial. You collaborate with colleagues to share insights and enhance the overall team knowledge;

    Incident post-mortems and continuous improvement: after resolving incidents, conduct post-mortem reviews to identify root causes, document findings, and suggest improvements to prevent similar incidents in the future. Actively participate in continuous improvement efforts to enhance system reliability and resilience;

    Security and compliance management: collaborate with security teams to ensure security controls and compliance requirements are met. Implement security measures, apply patches, and perform vulnerability assessments to protect against potential threats.

Network management:

    Capacity planning and optimization: analyse network traffic patterns, anticipate growth, and plan for future capacity requirements. This involves optimizing network configurations, adjusting bandwidth allocations, and scaling network resources;

    Physical hardware management: you are responsible for cabling, maintaining and monitoring the physical hardware in all Datacentres, offices and foreign offices;

    Network security management: you collaborate with security teams to ensure the network is adequately protected against potential threats. This includes implementing security measures, monitoring for anomalies and breaches, and conducting regular audits;

    Automation and tooling development: develop scripts, tools, and automation workflows to streamline network management tasks, such as device provisioning, configuration management, and monitoring.

Other duties

Infrastructure management:

    Infrastructure monitoring and alert management: monitor the infrastructure components, such as servers, virtual machines, containers, and cloud resources, to ensure their health and availability. Respond to alerts and take necessary actions to resolve issues promptly;

    Configuration management and automation: use configuration management systems or infrastructure-as-code to manage and automate the deployment and configuration of infrastructure resources. Maintain consistent configurations, track changes, and automate repetitive tasks;

    Capacity planning and resource optimization: analyse resource usage trends, forecast future demand, and plan accordingly. Optimize resource allocation, scale infrastructure, and recommend improvements to meet performance requirements;

    Disaster recovery: work on disaster recovery strategy and implement mechanisms to ensure data and service availability in case of disasters or failures. Conduct regular disaster recovery drills to validate recovery procedures and maintain readiness.

Database management:

    Database monitoring and performance optimization: monitor database performance metrics, identify bottlenecks or issues, and optimize configurations or queries to improve overall performance and response times;

    Backup and recovery management: you are responsible for implementing and maintaining database backup and recovery strategies to ensure data integrity and availability. They would regularly test and verify backup procedures to mitigate data loss risks;

    Database capacity planning and scalability: analyse database usage trends, predict growth patterns, and plan for future capacity requirements. This involves scaling the database infrastructure, optimizing resource allocation, and implementing sharing or partitioning strategies;

    Automation and tooling development: develop scripts, tools, or automation workflows to streamline database management tasks. This includes tasks such as database provisioning, schema management, data migrations, and monitoring.

Leading the development of a long-term technical strategy for our systems and infrastructure, with a focus on security and monitoring.

Making sure incidents are resolved efficiently, perform the root cause analysis and act to prevent other occurrences.
