About your new role:
We are seeking a Senior Software Engineer to lead the modernization of CommandLink’s critical billing, license management, and financial systems. This pivotal role involves transforming a legacy, monolithic PHP environment into a resilient, service-oriented architecture. Your work will ensure accurate billing, robust license enforcement, precise accounting, and reliable historical financial reporting at scale, without business disruption.
You will define technical direction, architect migration strategies, and lead engineering execution to deliver a modern, globally-ready financial platform known for its accuracy, compliance, and scalability. This role directly impacts revenue operations, customer trust, and our innovation speed. Billing, licensing, and accounting are fundamental to how value flows through our business, and getting this right is essential for confident scaling, faster innovation, and maintaining absolute trust with customers and partners.
If you are ready to own the modernization of a critical financial platform within a rapidly growing, large-scale company, this opportunity is for you.
Key Responsibilities:
- Architect the Future State: Design a modular, service-driven financial platform encompassing billing, license management, and accounting, capable of evolving with business needs.
- Lead Legacy-to-Modern Migration: Define and execute pragmatic migration strategies to transition from a monolithic system to a modern stack, ensuring seamless operations.
- Build Scalable Billing Services: Own the architecture for invoicing, payments, reconciliations, and revenue recognition, ensuring precision, reliability, and auditability.
- Integrate with Global Financial Systems: Architect integrations with ERP, payment gateways, and accounting platforms (e.g., NetSuite, QuickBooks, Stripe, Zuora, Chargebee).
- 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: Collaborate with Finance, Product, and Operations to align technology 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: Ability to guide teams, influence executives, and align cross-functional priorities efficiently.
