Freelance Remote Software Developer Jobs in Baltimore, MD

About the Role

We are hiring a Lead C++ Software Engineer to join our growing team developing NinjaOne’s automated endpoint management suite of software products, trusted by over 40,000 customers globally. You will develop high-impact software products used daily by IT teams and MSPs (managed service providers) to monitor, manage, and secure endpoints at scale. 

About the Team

Software Engineers own the full lifecycle of keeping endpoints up-to-date, from detecting available patches to safely applying them and rebooting. The work spans OS patches across multiple platforms (Windows Update, macOS software update, Linux package managers) and third-party application updates (3PP).

As a Lead Engineer on this team, you'll work on our C++ agent repo — the software that runs directly on customer devices with elevated system privileges to detect, install, and validate patches across Windows, macOS, and Linux. This means working close to the metal with system-level APIs, building resilient install and rollback logic, and reading and acting on policy owned by our mainline platform team. You'll be one of the most senior technical voices on the C++ side of Patching, helping shape architecture and mentoring other engineers as the team continues to grow.

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.

*Onsite interviews maybe required for this role

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

• Reviewing Code - Review code for correctness, maintainability, and architectural health
• Mentoring - Guide and grow senior and mid-level engineers on the team
• Process Implementation and Improvement - Identify gaps, propose fixes, and drive them through to completion
• Cross Team Collaboration - Align with mainline, catalog, and other patching squads on shared ownership and integration points
• Ensuring Product / Business Level Needs Are Engineered Into the Product - Translate roadmap priorities and customer needs into sound technical design
• Other duties as needed

About You

• Bachelor’s Degree in Computer Science, Engineering, Information Technology, or related technical field
• 10+ years of C++ development experience, Modern C++ (C++17 and above)
• Experience in Cross-platform development (Windows/macOS/Linux – Win32 API, POSIX)
• gRPC / Protocol Buffers
• SQLite / Embedded database patterns
• CMake
• Proficiency working with Qt and Vcpkg a strong plus
