About the Backup Team

At NinjaOne, the Backup Engineering team is solving one of IT’s hardest problems: protecting millions of endpoints, servers, and cloud-managed applications reliably, at scale, and from a single console. Our work spans three squads (Server Backup, Endpoint Backup, and SaaS Backup), covering everything from image-based bare-metal recovery to identity restore for Microsoft Entra. You’ll own software that 40,000+ customers worldwide trust to recover quickly when ransomware, hardware failures, or cloud outages strike.

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.

• Committing Code and Shipping Products: You will be one of our most trusted engineers committing code. Responsible for implementing design patterns and working on enterprise level software challenges in a startup environment. Impact product more hands-on than at other companies, building software of scale that runs on millions of endpoints.
• Debugging and Profiling: Debug and profile production Java services using tools like New Relic and structured log analysis; identify and resolve performance bottlenecks before they reach customers.
• Database Optimization: Design and optimize relational database schemas and queries for performance at scale, including index tuning, query planning, and storage efficiency improvements.
• Mentoring: Support the growth of engineers across the team through knowledge sharing, targeted feedback, and coaching to help build a stronger, more aligned engineering culture.
• Code Reviews: Conduct thorough peer code reviews, providing constructive, specific feedback and contributing to architecture discussions and key technical decisions.
• Documentation: Document system architecture, design tradeoffs, and operational procedures so that knowledge is shared and decisions are traceable across the team.
• Cross-team Collaboration: Collaborate with engineers across backend, infrastructure, and product teams to drive system reliability, integration, and long-term platform improvements.
• Other duties as needed

About You

• 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. Solid expertise in Kotlin will make you a standout candidate.
• 6+ years of experience designing and operating highly scalable software systems, with a proven ability to identify and solve scale challenges.
• Deep understanding of OOP design principles, with expertise in scaling data structures and object-oriented design for high-performance systems.
• Knowledge of API best practices and REST service development using frameworks like Jersey or Spring.
• Relational Database design, development, and performance optimization experience, including query tuning, index design, and schema optimization at scale.
• Experience with client-server development, event-driven architectures, and message brokers such as RabbitMQ, Amazon SQS, or SNS.
• Experience with caching systems (Redis a strong plus) and expert knowledge of quality testing practices.
• Excellent debugging and problem-solving skills, with the ability to diagnose complex issues across distributed systems and communicate findings clearly to engineering, product, and support stakeholders.
• Strong Linux and scripting fundamentals, with familiarity in containerization and orchestration tools such as Docker and Kubernetes for deploying and managing scalable, isolated workloads.
