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. \nThis 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. \nWhat You'll Do \nOwn 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. \nLead 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. \nWrite 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. \nRun 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. \nAutomate in Bash and Python. Replace manual runbooks with tooling and streamline repeatable work. \nOperate 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. \n Operate the traffic and data tier. Configure and troubleshoot Nginx and HAProxy (routing, TLS termination, health checks, connection handling) and support Redis and RabbitMQ in production. \nManage virtualization. Provision and maintain guests across VMware, Xen, or KVM, including capacity planning, host maintenance, and live migration. \nHandle secrets properly. Use Vault for secret storage, dynamic credentials, policy, and rotation - and help move the organization off whatever it was doing before. \nOwn observability. Maintain log aggregation on the Elastic Stack and alerting through Nagios, CheckMK, or Icinga. Tune alerts toward signal; an alert nobody can act on is a bug. \nWork through change management and code review. Everything moves through Git and pull requests. You will review other people's changes as seriously as you expect yours to be reviewed. \nWho You Are \n6+ years in a Linux systems, infrastructure, or SRE role. \nExpert-level Linux, specifically: \nPerformance analysis. 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. \nTroubleshooting methodology. A disciplined, hypothesis-driven approach that works on a system you have never seen before. We care more about how you narrow the problem than about which commands you happen to know. \nSystems fundamentals. Processes and signals, systemd, cgroups and namespaces, filesystems, and what actually happens when a host exhausts memory or file descriptors. \nDeclarative configuration management at production scale - Salt, Ansible, Chef, or Puppet. You have authored and maintained the code, not only run it. \nContainerization and orchestration. Production experience with Kubernetes or Nomad, including the operational realities: scheduling, resource pressure, rollouts, and debugging a workload that will not start. \nScripting and automation. Strong Bash and working Python. You write code that other engineers can maintain. \nFoundational networking. Comfortable across layers - VLANs and routing, DNS, DHCP, TCP behavior, and TLS - and able to determine whether a problem is the application, the host, or the network. \nProxy and load-balancing experience with Nginx or HAProxy. \nVirtualization experience with at least one of VMware, Xen, or KVM. \nGit and peer review as a daily habit, including the discipline to keep changes reviewable. \nExcellent written communication. Runbooks, design proposals, and incident write-ups are a core part of this job, not an afterthought. \nThe ability to get productive quickly in areas where you do not yet have depth. \nPreferred Qualifications \nProduction ownership of Redis or RabbitMQ as a primary responsibility rather than a dependency. \nVault administration - policies, auth methods, and rotation at scale. \nElastic Stack operations at volume: index lifecycle, mapping decisions, and cluster tuning. \nExperience in a regulated environment, or anywhere downtime has a direct revenue cost. \nColocation or bare-metal experience: hardware lifecycle, remote hands, and capacity planning against a finite footprint. \nCompany Perks + Benefits: \nPerformance Bonuses \nStock Purchase Options \nMedical/Vision/Dental Benefits \n401k Plan \n20 Paid Vacation Days (plus an additional paid vacation day the month of your birthday!) \n10 Paid Sick Days \nGym Membership Reimbursement \nCommuter Benefits \nPet Insurance \nWellness & Mental Health Programs \nCharitable Donation Matching \nTwo Paid Volunteer Days Off \nDaily catered lunch when in the office \nFull kitchen with snacks and beverages \nIn-building gym \nShuttle to/from Metra \nBase Salary Range: $140,000-$180,000 The actual salary offered will be based on the candidate's level of experience and qualifications. \nDiscretionary Performance Bonus: 10-12% of base salary based on individual and company performance. \nAbout IGNA + tasty \nIG North America is home to tastytrade, tastylive & tastyfx-a family of brands built to democratize trading and empower individual investors.
