Job description

NinjaOne unifies IT to simplify work for nearly 40,000 customers in 140+ countries
The NinjaOne Unified IT Operations Platform delivers endpoint management, autonomous patching, backup, and remote access in a single console to improve efficiency, increase resilience, and reduce spend. By automating IT and managing all endpoints, organizations give employees a great technology experience at work.
NinjaOne is obsessed with customer success and has retained a 98% customer satisfaction score for more than 5 years.

About the Role

As a Senior Software Engineer on the NinjaOne team, you will join a dedicated team building NinjaOne's ITSM capabilities, spanning our Ticketing and Billing products within the IT Operations suite. You'll design and implement scalable new solutions and product improvements that help IT teams and MSPs run their entire service operation, from managing tickets and automating workflows to turning that work into revenue through quoting, invoicing, and billing. On the Billing side, you'll build the systems MSPs rely on to monetize their services: generating accurate invoices from contracts and usage data, creating and managing quotes, and integrating with accounting platforms like QuickBooks and Xero so financial data flows seamlessly into the tools our customers already use.

This work demands precision, reliability, and a strong sense of ownership, when it comes to money, correctness isn't optional. A key part of what makes NinjaOne unique is the deep integration between these products and our endpoint management and RMM capabilities: technicians can take one-click remediation actions directly from a ticket, and the work they log flows straight through to billing. You'll help build and evolve that seamless, single-pane experience, from issue resolution to invoice.
