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. 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.
Key Responsibilities:
- Design a modular, service-driven financial platform—billing, license management, and accounting—that can evolve with the business.
- Define and execute pragmatic migration strategies that move us from a fragile monolith to a modern stack—without breaking existing operations.
- Own the architecture for invoicing, payments, reconciliations, and revenue recognition that must be precise, reliable, and auditable.
- Architect integrations with ERP, payment gateways, and accounting platforms (NetSuite, QuickBooks, Stripe, Zuora, Chargebee, etc.).
- Engineer for consistency, reconciliation, and historical accuracy across complex transactional systems.
- Drive observability, performance, and security across all financial services.
- Work directly with Finance, Product, and Operations to ensure technology aligns with compliance, business velocity, and customer impact.
- Takes on additional responsibilities and projects as needed to support the success of the team and organization.
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.
