Job description

About Vac

We are theVac Distributed Systems Testing R&D service unit. We specialize in developing software tools and methodologies to test and analyze the behavior of distributed systems within the Logos collective. Our primary objective is to ensure the scalability and reliability of Logos projects by providing comprehensive testing solutions. Through large network testing (e.g. using Kubernetes), we empower projects to evaluate the scaling behavior of their nodes within larger networks, and conduct thorough regression testing.

The role

We are looking for a talented and enthusiastic DevOps Engineer to join our Vac Distributed Systems Testing (DST) team. In this role, you will be a key contributor to ensuring the robustness, efficiency, and scalability of distributed systems across Vac and the Logos collective. Your primary duties will involve the conception, configuration, and optimization of distributed technologies such as Kubernetes. Your contributions will be instrumental in validating the functionality and performance of our distributed systems, making you a vital part of the DST team.

Key responsibilities

• Design, configure, and optimize Kubernetes clusters to support large-scale experiments and benchmarks of P2P technologies (e.g., libp2p, Waku, Codex, Nomos).
• Continuously improve cluster scalability and resource utilization, enabling increasingly complex deployments and experiments.
• Set up, maintain, and optimize supporting infrastructure such as monitoring, logging, and observability stacks (Grafana, Prometheus, Loki, etc.).
• 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, ELK/Loki, 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.
• 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.

Interview Process

• Interview with our POps team
• Interview with team member from the Vac team
• Take-home assignment and discussion of results with Vac and Codex
• Interview with Vac team lead

Compensation

The expected compensation range for this role is negotiable, dependent on how we assess your skills and experience throughout our interview process. We are happy to pay in any mix of fiat/crypto.
