DevOps Infrastructure Engineer / Systems Administrator

We're looking for a curious and driven DevOps Engineer to join our Site Reliability Engineering (SRE) team. This is a great opportunity for someone early in their career who wants real ownership and exposure to enterprise-scale infrastructure.

You'll work alongside experienced engineers to keep our global production and office environments running smoothly — a highly available WAN spanning multiple sites across the world. Day-to-day, you'll be involved in maintaining infrastructure, deploying configuration changes, troubleshooting platform issues, and contributing to the reliability of the systems that power payments for thousands of businesses.

This is a fully remote role based in the US, with occasional travel (1–4 times per year) to company colocation facilities, fully covered by NMI. If you're near one of our offices, we encourage occasional in-person collaboration too.

There is an on-call rotation as part of this role — you'll monitor infrastructure outside of core hours on a shared schedule and be expected to respond to issues promptly, either resolving or escalating them.

What you'll be doing:

• Supporting the day-to-day operations of our production infrastructure — resolving incidents, investigating alerts, and keeping systems healthy
• Helping maintain a regular patching cycle across Linux-based systems to meet security and compliance requirements
• Writing and maintaining Ansible playbooks or similar configuration management code to automate provisioning and configuration tasks
• Assisting with the deployment and management of cloud load balancers, WAFs, and other network infrastructure
• Contributing to hardware upgrades and replacements at colocation facilities
• Participating in incident reviews and post-mortems, helping identify root causes and preventative measures
• Collaborating with team members across time zones using clear written and verbal communication

Essential Skills & Experience

• 2–4 years of hands-on experience in a Linux systems or DevOps role
• Solid Linux fundamentals — comfortable administering servers, writing basic shell scripts, and configuring web servers (Red Hat/CentOS experience a bonus)
• Exposure to configuration management tools such as Ansible or Puppet
• Familiarity with DevOps workflows and tools — Git, GitLab, VS Code
• Good working knowledge of TCP/IP networking and how web traffic flows
• Understanding of TLS certificates and basic PKI concepts
• Strong attention to detail and a methodical approach to problem-solving
• Clear communicator who can document work and collaborate across teams and time zones

Preferred Skills & Experience

• Experience with cloud platforms (AWS, GCP, Azure)
• Exposure to load balancers (F5 BIG-IP or similar)
• Familiarity with observability tools such as Grafana, Prometheus, or the ELK stack
• Any exposure to WAF/DDoS platforms (Cloudflare, Akamai, F5 XC)
• Experience with Redis, RabbitMQ, or HashiCorp Vault
• Familiarity with line of business tools such as Confluence, Netbox, and Jira

As well as being a part of something exciting everyday, you will also receive the following benefits:

• Annual salary of $75,000 - $87,000 + bonus
• A remote first culture!
• Flex PTO 
• Health, Dental and Vision Insurance
• 13 Paid Holidays
• Company volunteer days
