Platform Engineer (Network Solutions)

About Nexcess

Nexcess provides specialty cloud solutions for organizations where performance and compliance have to coexist. We serve businesses worldwide, from agencies scaling client sites to enterprises running mission-critical operations. We've built our reputation on deep technical expertise and genuine partnership with every client we work with. Behind every environment we manage is a team of people who take the craft seriously and keep showing up when it matters.

The Network Solutions team engineers and maintains the networking products — load balancing, switching, firewalls, VPN, VPC, and GPF — that connect and protect our customers’ infrastructure.

You will own platform changes end to end: the specification, the automation and configuration, the validation, and how they behave in production.

The pull request is the visible part. The job is the machine behind it: turning a loosely worded need into something precise enough to build against, naming what can break before it does, proving the change is correct rather than asserting it, and staying with it once it is live.

How we work

• Business alignment and focus come first. Engineering here exists to move the business, not to be busy. You will know which few things matter most this month and why, say so when the work in front of you is not one of them, and land what you committed to on dates the business can plan around, at a quality that does not come back as an incident or a customer escalation.
• Predictable, reliable delivery of quality software is the output of this job, and everything below is in service of it.
• This job gets more hands-on every quarter, not less. The volume of code goes up while the time you spend typing it goes down, so the value moves to the two ends of it: what you specify, and what you verify. You will stay close to production, run the AI harness daily, read code you did not write, and keep your technical judgment current rather than remembered.
• Whoever ships it owns it, regardless of what wrote it. Most code is AI-generated now, so the judgment moved to either side of it: specifying exactly what to build, and verifying that what came back is correct, secure and operable. An agent wrote it is not a defense. Your name is on the merge.
• You do not need to own the roadmap to know why the work matters. You will not be the Product counterpart at this level and you are not expected to be. You are expected to understand what the customer gets and what the business gains from the thing you are building, and to ask before you build the wrong thing correctly. The engineers who move fastest here are the ones who ask that question early rather than at the review.
• You go on call for what you build, and you take your turn on the rotation. Engineering declares risk and timelines in writing for the business to accept, and that includes yours: when a date is at risk you say so early, with evidence, rather than quietly.

Responsibilities

• Own platform features end to end within the Network Solutions domain. Take work from specification through implementation, testing, deployment, monitoring, and ongoing production support across load balancing, switching, firewalls, VPN, VPC, and related networking services.
• Build and maintain network-focused cloud infrastructure. Work with Linux-based systems, configuration management, and supporting infrastructure to deliver reliable and scalable networking services.
• Automate infrastructure configuration and operational processes. Use tools such as Ansible or Puppet to reduce manual work, improve consistency, and make changes repeatable and auditable.
• Support and improve networking platforms and services. Work closely with network infrastructure and core networking components to ensure stable, secure, and performant operation.
• Translate requirements into clear technical specifications. Identify dependencies, failure scenarios, and operational risks early and resolve ambiguity before implementation begins.
• Verify changes before they reach production. Test infrastructure and software changes, exercise failure scenarios, and provide clear evidence that changes are safe and production-ready.
• Use AI-assisted engineering tools as part of your daily workflow. Apply agentic tooling to implementation, automation, and review while remaining accountable for the quality and operability of the final result.
• Review infrastructure and code changes from other engineers. Identify design, reliability, security, and operational risks early and provide clear, actionable feedback.
• Own the systems you run. Participate in on-call rotation, respond to incidents, document root causes and follow-up actions, and continuously reduce operational toil.
• Work safely in existing and unfamiliar systems. Understand complex or legacy environments, make incremental improvements without unnecessary rewrites, and leave systems better documented and instrumented than you found them.
• Mentor other engineers. Share technical knowledge, explain design and operational decisions, and support less experienced engineers through implementation and review.
• Coordinate dependencies across teams. Identify cross-team requirements early and work directly with the relevant engineers to avoid delivery blockers.

Requirements

• 5+ years of experience with cloud computing infrastructure configuration and production environments.
• 5+ years of experience with Linux server administration.
• 5+ years of experience with configuration management and automation tools such as Ansible or Puppet.
• Strong understanding of infrastructure reliability, availability, security, and production operations.
• Experience building, operating, and supporting highly available production infrastructure.
• Experience automating infrastructure configuration and operational processes.
• Experience participating in an on-call rotation and responding to production incidents.
• Ability to troubleshoot complex issues across multiple infrastructure layers.
• Ability to work effectively in unfamiliar or legacy environments and make safe, incremental improvements.
• Hands-on experience with AI-assisted engineering tools as part of day-to-day technical work.
• Clear written communication skills and the ability to work effectively in a remote, distributed team across multiple time zones.

Preferred

• 5+ years of experience with core networking administration.
