Freelance Remote Junior Software Developer Jobs in Baltimore, MD

About the Team

Do you love scripting, dissecting installers, and building automation at scale? We are looking for a Junior Software Packaging Engineer to Join NinjaOne’s Catalog team. This team builds and maintains the third-party software catalog that powers automated patching across managed endpoints. You will research vendor applications, analyze installers, and build package metadata that powers our RMM’s third-party patching engine. Your work will directly influence the reliability and security of thousands of organizations around the world.

You will join our Software Engineering team, working alongside other Software Product Engineers. Collaborating with our Product Managers, Software Development Engineers, and our Support Engineers. You will work with like-minded individuals to deliver exceptional, production-ready automation content for NinjaOne clients.

Location - We are flexible on remote working from home, if you are located in the USA and reside in one of the following states - CA, CO, CT, FL, GA, *IL, KS, MA, MD, ME, NJ, NC, NY, OR, TN, TX, VA, and WA. We have physical offices in Austin, TX and Tampa, FL, if you prefer a hybrid option.

We hire the best software engineers, but experience in our stack can’t hurt: NinjaOne is built on Java, Kotlin, C++, Golang and Postgres; supporting millions of user endpoints and running as a scalable cloud service in AWS. Knowing large-scale datastore bottlenecks, asynchronous application design and client-server architecture will help you.

What You’ll Be Doing

Third-Party Patch Packaging & Content Development

• Build high-quality software packages for our patching platform, including installer metadata, detection logic, and automation scripts.
• Analyze vendor installers (MSI, EXE, custom frameworks) to determine silent install parameters, upgrade behavior, and OS compatibility.
• Automatically detect new software versions from vendor websites.
• Develop endpoint-side scripts to download, install, upgrade, and verify third-party applications.

Strategic Research & Standards Development

•         Research vendor release patterns, installer technologies, and best practices for secure and reliable patching.

•         Define and maintain packaging standards that improve consistency, reliability, and security across all supported applications.

•         Continuously enhance our package catalog to reflect evolving IT and security requirements.

Frontline Automation & Rapid Response

• Build one-off or urgent automation scripts in response to emerging vulnerabilities, vendor changes, or customer needs.
• Troubleshoot packaging issues, installer failures, and automation edge cases.
• Partner with Support and Engineering teams to resolve customer-impacting issues quickly and effectively.

Other duties as needed

Required Qualifications

• 2 to 3 years of professional experience in a software development, scripting, or technical IT role.
• Familiarity operating at the Windows OS level: registry structure (HKLM/HKCU, including how WOW6432Node redirects 32-bit apps on 64 bit systems), file system layout and permissions, and how services and processes work.
• Experience with Scripting languages or OOP languages
• Working knowledge of Git
• Comfortable using AI coding assistants like Copilot or Claude as part of your normal workflow

Nice to Have

• Hands on PowerShell experience.
• Some exposure to macOS packaging or Zsh scripting.
• Exposure to endpoint management platforms.
• Exposure to CI/CD pipelines
• Familiarity with a unit testing framework
• Exposure to VM based software validation workflows

What We’re Looking For

•         Curiosity and a builder’s mindset. Side projects, self-directed learning, or community contributions are all good signs.

•         Genuine care about getting the details right. A bad detection rule or an unhandled exit code should feel like a real problem to fix, not just a checkbox to close.

•         Comfortable asking questions and taking feedback while you’re still learning a new domain.
