About Your New Role
CommandLink is seeking a Staff Software Engineer to lead the modernization of our billing, license management, and financial systems — the core engines powering our rapidly growing global SaaS platform.
This is not a maintenance role. You’ll be reimagining how financial transactions, licensing, and accounting flow through a multi‑continent enterprise — transforming a legacy PHP monolith into a modern, service‑oriented architecture designed for scalability, accuracy, and resilience.
You’ll define the technical vision, shape the architecture, and guide the migration roadmap — ensuring that CommandLink’s global financial systems are built to handle growth, complexity, and compliance at scale. Your work will directly influence how value moves across borders, ensuring every invoice, payment, and reconciliation is reliable, auditable, and secure.
Key Responsibilities
Help design the next‑gen financial platform for billing, licensing, and accounting.
Guide our move from a legacy PHP setup to a modern, service‑based architecture.
Build systems that handle invoices, payments, and revenue recognition — reliably and globally.
Integrate with platforms like NetSuite, Stripe, QuickBooks, Zuora, and Chargebee.
Ensure data accuracy, reconciliation, and auditability across all transactions.
Set standards for performance, observability, and security across our financial stack.
Work closely with Finance, Product, and Operations to turn business needs into scalable tech.
What You'll Need For Success
10+ years of experience building and scaling reliable backend systems.
Proven experience modernizing legacy apps (bonus if PHP) into modular, service‑oriented architectures.
Strong background integrating with ERP, payment, and accounting systems (NetSuite is a plus).
Experience building systems that support global scale and high transaction volume.
Solid understanding of PCI, SOC2, GDPR, and modern authentication standards like OAuth 2.0.
Hands‑on experience in Azure (preferred), AWS, or GCP.
Ability to guide teams, influence decisions, and drive progress without red tape.
