Spoiler: Your next challenge in serious decentralized tech starts right here.
At Pearster, we're partnering with a leading infrastructure company in the blockchain space to find a Senior Infrastructure Engineer (Core Systems) who is comfortable owning the infrastructure underneath mission-critical blockchain services.
This is not a traditional DevOps or application-platform role.
We're looking for a hands-on infrastructure engineer with strong systems administration fundamentals who can design, build, troubleshoot, and operate the underlying compute, storage, networking, virtualization, and Kubernetes layers.
You'll work across bare-metal infrastructure, Linux systems, Kubernetes, virtualization, storage, networking, and cloud environments, taking ownership from architecture and provisioning through production operations and incident response.
The infrastructure you help build supports blockchain services used by developers and businesses worldwide, so reliability, operational judgment, and the ability to troubleshoot complex systems are essential.
Design, build, and operate production infrastructure across bare-metal, virtualized, containerized, and cloud environments.
Build, administer, troubleshoot, and scale large Kubernetes environments supporting mission-critical workloads.
Own infrastructure decisions from architecture and implementation through production operations and incident response.
Provision, configure, and maintain physical and virtual servers, including compute, storage, networking, and operating system layers.
Design and implement Infrastructure as Code and configuration management using tools such as Terraform, Ansible, Consul, or similar technologies.
Automate server provisioning, infrastructure deployment, configuration, upgrades, and recurring operational workflows.
Troubleshoot complex production issues across Linux, networking, compute, storage, virtualization, and Kubernetes.
Work with production storage systems, including local and block storage, NVMe, redundancy, performance, durability, and failure scenarios.
Research, evaluate, and implement new infrastructure technologies and proof-of-concepts.
Collaborate with Platform, CloudOps, and Technical Operations teams while maintaining clear ownership of core infrastructure.
Improve observability, capacity planning, scalability, reliability, and infrastructure performance.
Lead and contribute to incident response, root-cause analysis, and postmortems.
Identify systemic risks and turn incidents into long-term infrastructure improvements.
Contribute to infrastructure architecture, standards, runbooks, and technical documentation.
Exercise independent technical judgment and constructively challenge architectural or operational decisions when you identify risks.
Participate in a 24/7 on-call rotation, typically one week every 6–7 weeks.
5+ years of hands-on Infrastructure Engineering, Systems Engineering, or Systems Administration experience.
Strong Linux/Unix systems administration fundamentals and experience troubleshooting production systems at the OS level.
Hands-on experience administering bare-metal infrastructure in production, including server provisioning, configuration, hardware troubleshooting, storage, networking, and lifecycle management.
Deep production experience with Kubernetes, including building, administering, troubleshooting, upgrading, and scaling clusters — not only deploying applications or workloads onto managed Kubernetes services.
Experience owning infrastructure across hybrid environments spanning physical infrastructure, virtualization, containers, and cloud platforms.
Strong understanding of compute, networking, storage, virtualization, containers, redundancy, scalability, and high availability.
Experience working with production storage technologies and an understanding of NVMe, disk and storage failure scenarios, performance, redundancy, and data durability.
Hands-on experience with Infrastructure as Code and automation tools such as Terraform, Ansible, or similar technologies.
Experience with observability and monitoring platforms such as Grafana, ELK, VictoriaMetrics, Datadog, or similar tools.
Programming or scripting experience with Python, Go, JavaScript, Bash, or similar languages.
Strong troubleshooting skills and the ability to diagnose failures across multiple layers of the infrastructure stack.
Experience responding to production incidents and participating in root-cause analysis and postmortems.
Demonstrated experience making infrastructure design and architecture decisions, rather than primarily executing runbooks or operating systems designed by others.
Ability to take ownership of infrastructure problems from initial investigation through resolution and long-term remediation.
Comfortable working independently in a highly technical, hands-on individual contributor role.
Experience operating blockchain nodes, validators, sequencers, or other Web3 infrastructure in production.
Experience supporting stateful and distributed blockchain workloads where availability, data integrity, and failure recovery are critical.
Experience operating infrastructure at significant scale.
Experience with KVM/QEMU or similar virtualization technologies.
Experience working across both public cloud and privately operated infrastructure.
Experience designing infrastructure for high-performance or storage-intensive workloads.
Experience in startup or other fast-moving engineering environments.
Blockchain experience is valuable, but deep infrastructure engineering experience is more important than previous Web3 experience.
Work remotely from anywhere in LATAM.
Competitive compensation paid in USD.
Paid time off.
International certification support.
Coworking space allowance.
English classes.
Referral bonus program.
Team events and welcome kit.
At Pearster, your journey matters, and we’re here to help you go further than you imagined.
