Senior Software Engineer, Java - Content Team

About the role

We are looking for a Senior Software Engineer to join a newly formed team focused on accelerating the capabilities of the Ninja One platform through manifest-driven development. This team is being built from the ground up and has ambitious goals to remake how Ninja One delivers features — with a direct, visible impact on customer value.

The team's mission is to build flexible, customizable experiences that let customers and MSPs tailor the platform to their own workflows — from UI components to deeper integrations. We're still early in this journey, with a lot of the vision ahead of us rather than behind. If you're excited about designing extensible systems that put more power in users' hands, this is a great place to have that impact.

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:
Ninja One is built on Java, Kotlin, Python, 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.

• Manifest-driven development to extend Ninja One platform capabilities.
• Python development to create workers that extend Ninja One’s value via third-party integrations.
• Java and Kotlin backend development to expose Ninja One platform functions for extensibility.
• Collaborate with the AI workflow, server, and platform teams to achieve the team’s mission.
• Participate in architecture and design reviews to build high-quality software that is scalable and API‑first.
• Troubleshoot production issues across the technical stack using logs, metrics, and traces.
• Other duties as needed.

• Bachelor’s degree in Computer Science, Computer Engineering, Information Technology, or equivalent work experience.
• 10+ years of experience in Java software development for product applications, or equivalent, with solid expertise in Kotlin. Python experience is a plus but not required — we value adaptable engineers who can work across languages as needed.
• 4+ years of experience working with highly scalable software systems.
• Experience leveraging AI tooling to accelerate software development.
• Experience working on systems at scale and finding solutions to scale systems further.
• Working knowledge of a breadth of OOP design principles.
• Expertise in scaling data structures and object-oriented design.
• Knowledge of API best practices and REST service development using frameworks like Jersey or Spring.
• Relational database design and development experience.
• Experience with both client- and server‑side development for responsive messaging.
• Caching systems expertise; experience with Redis will make you a standout candidate.
• Expert knowledge of quality testing practices.
