We are looking for a talented and enthusiastic DevOps Engineer to join our Distributed Systems Testing (DST) team.
You'll be responsible for designing and executing comprehensive evaluation strategies, leveraging both large-scale lab deployments and protocol behavior modeling scripts. Your expertise will be crucial in analyzing these complex distributed systems, automating intricate test scenarios, and providing in-depth insights into system behaviors.
Working closely with cross-functional teams, you'll troubleshoot complex issues and translate technical data into actionable recommendations. Proficiency in containerization, cloud technologies, and distributed systems principles is essential.

Key responsibilities

• Design, configure, and optimize Kubernetes clusters to support large-scale experiments and benchmarks of P2P technologies.
• Continuously improve cluster scalability and resource utilization, enabling increasingly complex deployments and experiments.

• Collaborate with DST researchers and engineers to streamline experimentation workflows and make analysis easier and more reproducible.
• Automate infrastructure and deployment workflows to increase reliability and reduce overhead.
• Troubleshoot, profile, and tune distributed workloads to ensure accurate and performant benchmarking.
• Identify, reproduce, and debug complex issues in distributed systems, working closely with Logos development teams.

You ideally will have

• Strong experience with Kubernetes and container orchestration in production or research environments.
• Solid understanding of cloud infrastructure, Linux systems, and networking (especially relevant to distributed/P2P systems).
• Familiarity with monitoring and logging tools (Grafana, Prometheus, VictoriaLogs, etc.).
• Experience with infrastructure as code (Terraform, Ansible, Helm, etc.).
• Proficiency in at least one scripting/programming language (ideally Python).
• Interest in or experience with distributed systems, P2P networks, or blockchain technologies.
• Experience with networks and systems programming.
• Excellent written and conversational communication skills.
• Alignment with our core values and principles.

Bonus points

• Hands-on experience with libp2p or projects in the Logos collective.
• Background in performance benchmarking, scalability testing, or systems research.
• Contributions to open source projects.
• Experience working for an open-source organization.
