About Your New Role 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. 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. Key Responsibilities Architect the Future State: Design a modular, service-driven financial platform—billing, license management, and accounting—that can evolve with the business. Lead Legacy-to-Modern Migration: Define and execute pragmatic migration strategies that move us from a fragile monolith to a modern stack—without breaking existing operations. Build Scalable Billing Services: Own the architecture for invoicing, payments, reconciliations, and revenue recognition that must be precise, reliable, and auditable. Integrate with Global Financial Systems: Architect integrations with ERP, payment gateways, and accounting platforms (NetSuite, QuickBooks, Stripe, Zuora, Chargebee, etc.). Guarantee Data Integrity: Engineer for consistency, reconciliation, and historical accuracy across complex transactional systems. Set Standards: Drive observability, performance, and security across all financial services. Cross-Functional Leadership: Work directly with Finance, Product, and Operations to ensure technology aligns with compliance, business velocity, and customer impact. 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.
