About the role

  • We are looking for a senior Linux engineer who is equal parts operator and builder.
  • This is not a role where the abstractions hide the machine.
  • You are expected to be curious about what is underneath and to be the person other engineers come to when a system is behaving in a way nobody can explain.

Responsibilities

  • Own Linux performance. Diagnose and tune systems under real production load: CPU scheduling and NUMA placement, memory and page cache behavior, disk and filesystem I/O, and network stack tuning.
  • Lead troubleshooting on hard problems.
  • Write and maintain configuration management code. Build infrastructure declaratively with Salt, Ansible, Chef, or Puppet, treating that code with the same standards as application code: reviewed, tested, and version-controlled.
  • Operate core network services. Troubleshoot TCP/IP with confidence and bring solid networking fundamentals. Manage DNS and DHCP as production services - zone management, resolver behavior, TTL strategy, scopes, reservations, and relay configuration.
  • Manage virtualization. Provision and maintain guests across VMware, Xen, or KVM, including capacity planning, host maintenance, and live migration.
  • Own observability. Maintain log aggregation on the Elastic Stack and alerting through Nagios, CheckMK, or Icinga. Tune alerts toward signal

Requirements

  • 6+ years in a Linux systems, infrastructure, or SRE role.
  • You can go from a vague complaint to a named subsystem using the standard tooling - perf, strace, ss, iostat, bpftrace, or equivalents - and explain what the numbers mean.
  • A disciplined, hypothesis-driven approach that works on a system you have never seen before.
  • You have authored and maintained the code, not only run it.
  • Production experience with Kubernetes or Nomad, including the operational realities: scheduling, resource pressure, rollouts, and debugging a workload that will not start.

Benefits

  • Build, deploy, and operate services on Kubernetes or Nomad, including scheduling behavior, resource limits, health checking, and the failure modes that only appear under contention.
  • Configure and troubleshoot Nginx and HAProxy (routing, TLS termination, health checks, connection handling) and support Redis and RabbitMQ in production.

Company info

  • About the Role
  • You will own the systems layer of our production environment - from the metal to the configuration management code.
  • This is a hands-on role: you will jump into incidents, tackle challenging engineering problems, design systems that scale, and evaluate new software and architectures.
  • Lead troubleshooting on hard problems. Work incidents methodically - form a hypothesis, find the cheapest test that falsifies it, and narrow the search rather than changing five things at once. Write postmortems, organize follow-up tasks, and future-proof the environment so the same issue does not recur.
  • Run containerized workloads. Build, deploy, and operate services on Kubernetes or Nomad, including scheduling behavior, resource limits, health checking, and the failure modes that only appear under contention.
  • Automate in Bash and Python. Replace manual runbooks with tooling and streamline repeatable work.
