Staff Software Engineer, Billing

Staff Software Engineer, Billing & Financial Systems Command|Link is a global SaaS Platform providing network, voice services, and IT security solutions, helping corporations consolidate their core infrastructure into a single vendor and layering on a proprietary single pane of glass platform. Command|Link has revolutionized the IT industry by tackling the problems our competitors create. In recognition for our unprecedented innovation and dedication, Command|Link was recognized as the SD-WAN Product of the Year, ITSM Visionary Spotlight, UCaaS Product of the Year, NaaS Product of the Year, Supplier of the Year, and the AT&T Strategic Growth Partner. Command|Link has built the only IT platform for scale that solves ISP vendor sprawl and IT headaches. We make it easy for our customers to get more done, maximize uptime and improve the bottom line. We’re looking for a Staff Software Engineer to lead the modernization of CommandLink’s billing, license management, and financial systems—the backbone of our fast-growing SaaS enterprise. This isn’t about incremental feature work. It’s about transforming a legacy, monolithic PHP environment into a resilient, service-oriented architecture that powers accurate billing, license enforcement, accounting, and historical financial reporting—at scale, without disrupting the business. You’ll set the technical direction, architect migration strategies, and lead engineering execution to ensure we deliver a modern, global-ready financial platform that’s bulletproof in accuracy, compliance, and scalability. Your work directly impacts revenue operations, customer trust, and the speed at which we can innovate. Billing, licensing, and accounting aren’t back-office functions—they are the system of record for how value flows through our business. Getting this right means we can scale confidently, innovate faster, and maintain absolute trust with customers and partners. If you want to own the modernization of a critical financial platform at a company already at massive scale and still growing fast—this is the role. What you\'ll need for success: Deep Engineering Experience : 10+ years building and scaling backend systems with strong fundamentals in transactional integrity, distributed systems, and service architectures. Proven Modernization Track Record : Hands-on experience decomposing legacy systems (especially PHP-based) into modern service platforms. Integration Mastery : Strong history integrating with ERP, accounting, and payment systems (NetSuite expertise highly valued). Architect at Scale : Skilled at building high-volume, high-accuracy financial systems with global reach. Security & Compliance : Solid knowledge of PCI, SOC2, GDPR, authentication protocols (OAuth 2.0, HMAC, mTLS), and data handling best practices. Cloud-Native Mindset : Experience architecting and deploying in Azure (preferred), AWS, or GCP. Leadership Without Bureaucracy : Able to guide teams, influence executives, and align cross-functional priorities without slowing execution.
