Site Reliability Engineer Intern (f/m)

As a Site Reliability Engineer Intern at Ledger, you will assist in maintaining and improving our CI/CD pipelines using Kubernetes and AWS. Your responsibilities will include automating infrastructure provisioning with Terraform and Ansible, developing monitoring solutions, and collaborating with the development team to securely manage web applications. In addition, you will have the chance to enhance the developer experience through the integration of Backstage, making your impact felt across the organization.

To qualify for the Site Reliability Engineer Intern role at Ledger, you must be a Master's student and possess a six-month internship agreement from your school. Proficiency in Unix/Linux environments, Git, Python, and Terraform is essential. Additionally, familiarity with Kubernetes, AWS solutions, and CI/CD tools will greatly benefit your application. Strong problem-solving skills, collaboration, and excellent communication are also necessary.

To prepare for your interview at Ledger for the Site Reliability Engineer Intern position, familiarize yourself with DevOps principles, the tools listed in the job description, and best practices in site reliability engineering. Brush up on your problem-solving skills and be ready to discuss your experience with cloud services, infrastructure as code, and monitoring systems. Additionally, prepare to articulate how your academic background and projects have equipped you for this role.

During your internship at Ledger, you'll gain invaluable experience in a real-world DevOps and SRE setting. You'll work hands-on with AWS services, learn about Infrastructure as Code using Terraform, and develop effective monitoring and logging solutions. Additionally, you will explore Backstage and its capabilities, equipping you with skills that are highly sought after in the tech industry.

Ledger offers various perks to its Site Reliability Engineer Interns, including the option for partial remote work, frequent social events, and reimbursements for transportation costs. You can also enjoy lunch vouchers and accrue vacation days, ensuring a healthy work-life balance while you gain experience in the digital assets space.

Site Reliability Engineering focuses on ensuring systems are reliable, scalable, and efficient. Unlike traditional IT, which may be more reactive, SRE emphasizes proactive measures, automation, and a strong focus on performance metrics to maintain system health. Be prepared to highlight your understanding of these differences.

In your response, discuss specific projects where you've designed or maintained CI/CD pipelines. Explain the tools you used, such as Jenkins or GitHub Actions, and how they helped streamline deployments. Highlight any challenges faced and how you overcame them.

Talk about your approach to monitoring, logging, and alerting. Mention tools like Datadog or Grafana that you've used to maintain observability, and explain how you leverage these tools to preemptively identify and solve issues that might compromise infrastructure reliability.

Share a specific instance where you used a tool like Terraform or Ansible to automate a previously manual task. Explain the process, the impact of your automation on efficiency, and the positive outcomes it led to, such as time savings or reduced errors.

Infrastructure as Code is the practice of managing and provisioning infrastructure through code rather than manual processes. This is important because it allows for consistent and repeatable deployments, reduces the risk of human error, and enhances collaboration among team members. Be sure to connect this to your own experiences with tools like Terraform.

Discuss tools and strategies used for monitoring and logging microservices, such as centralized logging with tools like ELK stack or monitoring with Prometheus. Highlight how you ensure visibility across services and how you respond to alerts.

Explain your familiarity with Kubernetes and how you've used it in previous projects. Discuss aspects like deploying applications, using Helm for package management, and managing containerized applications at scale.

Share your strategies for prioritizing tasks like using Agile methodologies or tools like Kanban boards. Emphasize your ability to stay calm under pressure and communicate effectively with your team to ensure critical issues are addressed promptly.

Describe your approach to ensuring code quality through techniques like code reviews, testing, and adhering to best practices. Mention specific tools or frameworks you've used to enforce coding standards and facilitate peer feedback.

Propound on the fast-paced nature of the role—balancing proactive system improvements with reactive problem-solving. Discuss how you approach this challenge through continuous learning and adapting to evolving technologies.
