Overview
Cotiviti is a leading solutions and analytics company that leverages unparalleled clinical and financial datasets to deliver deep insight into the performance of the healthcare system. These insights uncover new opportunities for healthcare organizations to collaborate to improve their financial performance, reduce inefficiency, and improve healthcare quality.
We are hiring Software Engineer to help our Infrastructure, Windows Engineering, and Application Development teams validate that Cotiviti applications continue to work correctly after Windows/Linux Server upgrades, server replacements, third-party application upgrades, .NET framework updates, and web application vulnerability fixes. This is a hands-on, Windows/Linux-focused role centered on testing, comparing pre- and  post-upgrade behavior, and confirming that nothing has regressed. You will work under the close guidance of senior engineers, who will provide context, ramp-up support, and mentoring. Cotiviti develops innovative applications in healthcare analytics, and this position helps keep the underlying Windows/Linux platforms current, secure, and supportable so the business can continue to deliver value to our clients.
This role is a strong fit for application support engineers, QA engineers, or junior .NET developers who enjoy methodical validation work in Windows/Linux environments.
Responsibilities
- Validate and test that homegrown, third-party applications, services, scheduled jobs, and integrations behave the same on upgraded or replacement Windows servers as they did on the prior environment.
- Execute manual, functional, regression, and smoke tests against migrated/upgraded servers and document results, defects, and parity findings clearly.
- Support testing and rollout activities for upgrades of end-of-life Windows Server operating systems, working alongside Infrastructure and Windows Engineering teams.
- Help verify third-party application upgrades and .NET framework updates by running the application, checking behavior, reviewing event logs, and reporting issues to the responsible developer.
- Retest web application vulnerability fixes (OWASP-class issues, library CVEs) after developers apply changes, confirming the issue is resolved and nothing else broke.
- Compare pre- and post-upgrade behavior of homegrown MS Access applications, Windows services, IIS-hosted web applications, application pools, scheduled tasks, file/share permissions, and database connectivity, and report any deviations.
- Follow change-control processes and keep clean records of tests run, evidence collected, and issues found.
- Escalate complex or ambiguous issues to senior engineers and learn from their guidance.
- Complete other related duties as assigned.
- Must be able to perform duties with or without reasonable accommodation.
Qualifications
- Bachelor’s Degree in Computer Science, Information Technology, Information Systems, or related field.
- Strong manual, functional, regression, and smoke testing skills, including the ability to write and follow test cases and document results.   
- 1–3 years of professional experience in any of the following: application support, QA / software testing, junior software development, or Windows systems administration.
- Comfort working on Windows Server (logging in, navigating services, viewing event logs, checking IIS and scheduled tasks). Deep admin expertise is not required.
- Ability to read VBA, Java, C# / .NET code well enough to follow application flow and discuss findings with developers. You do not need to be a heavy .NET writer.
- Strong written and verbal communication and attention to detail.
- Ability to execute on project deliverables in a dynamic, fast paced environment within estimated timelines
- Strong analytical, organizational, and interpersonal skills
- Willingness to learn, ask questions, and follow defined change-management and documentation procedures.
Nice to Have (Any of These Are a Plus — None Are Required)
- PowerShell scripting for routine validation or automation tasks.
- Exposure to IIS, application pools, and ASP.NET   / ASP.NET   Core hosting.
- Basic SQL Server / T-SQL skills for spot-checking data after upgrades.
- Experience participating in any Windows Server, SQL Server, or .NET upgrade/migration project.
- Familiarity with vulnerability scanning or retest workflows using tools such as Veracode, OWASP ZAP, or Burp Suite.
