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.

Overview

Cloud Services delivers the data protection, security, and edge services — SSL, email, EADN, and CDN/WAF — that keep our customers’ applications safe and performant.

You will own features end to end: the specification, the code, the tests and how it behaves in production. This is an individual contributor role with no direct reports, and you are the engineer who answers for whether what you shipped actually works.

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 quality end to end within the Cloud Services domain. Take responsibility for how features are validated from specification through development, testing, deployment, and production.
• Build and maintain automated testing frameworks and test coverage. Develop reliable automated tests that provide confidence in new functionality, regression coverage, and production readiness.
• Define testing strategy early in the development process. Identify risks, edge cases, dependencies, and failure scenarios before implementation is complete, rather than discovering them at the end.
• Translate requirements into clear and testable acceptance criteria. Work with engineers and stakeholders to remove ambiguity and make sure expected behavior can be verified objectively.
• Verify changes and provide evidence. Test both expected behavior and failure scenarios, validate coverage on changed code, and ensure pull requests contain clear evidence that changes are ready for production.
• Use AI-assisted engineering tools as part of your daily workflow. Apply agentic tooling to testing, review, and automation while critically validating generated output and remaining accountable for the final result.
• Review code and test changes from other engineers. Identify quality, reliability, and design risks early and provide clear, actionable feedback.
• Improve testing efficiency and reduce manual effort. Identify repetitive validation work and replace it with reliable automation wherever practical.
• Support production quality. Participate in incident analysis, help identify gaps in test coverage, and ensure production issues lead to improvements in automated testing and engineering practices.
• Mentor other engineers in quality practices. Share testing approaches, automation techniques, and quality standards across the team.
• Work across existing and unfamiliar systems. Understand how different components interact and build effective test coverage for complex or legacy systems without requiring them to be rewritten.
• Coordinate quality dependencies across teams. Identify integration risks early and work directly with relevant engineers to ensure cross-team changes are tested appropriately.

Qualifications

Required

• 5+ years of experience with automated testing frameworks and software quality engineering.
• Strong experience designing, building, and maintaining automated test suites for production software.
• Experience testing complex production systems across multiple components or services.
• Strong understanding of software testing principles, including functional, integration, regression, and failure-path testing.
• Experience defining test strategies and translating requirements into clear, testable acceptance criteria.
• Experience working closely with software engineers throughout the development lifecycle rather than testing only after development is complete.
• Ability to read and understand application code well enough to identify risks, test gaps, and potential defects.
• Experience with production systems and incident analysis, including using production issues to improve test coverage.
• Hands-on experience with AI-assisted engineering or testing tools as part of day-to-day technical work.
• Strong written communication skills and the ability to work effectively in a remote, distributed team across multiple time zones.

Preferred

• 5+ years of experience with CDN, WAF, and server security.
• Experience with one or more of the following technologies: Perl, PHP, React, or Vue.
• Experience in managed hosting, cloud platforms, or another high-availability service environment.
• Experience building or improving CI/CD-integrated automated testing.
• Experience mentoring engineers or helping establish quality and testing standards across a team.
