About your new role:
We are not looking for a maintenance engineer. We are seeking a Staff Software Engineer to act as the primary architect for our next-generation financial platform. Our goal is to decommission a legacy PHP monolith and replace it with a modern, high-performance, and resilient service-oriented architecture (SOA) capable of handling billions of global transactions with 100% accuracy.
You will be the technical lead for our billing, license management, and revenue recognition systems—the core engines of our business. This role is about more than just refactoring; it is about engineering the distributed systems primitives that ensure every invoice, payment, and reconciliation is reliable, auditable, and secure at a global scale.
Key Strategic Responsibilities
-
System Re-Architecture: Lead the transition from a monolithic legacy stack to a modern SOA using the Strangler Fig pattern, ensuring zero downtime and complete data parity.
-
Engineering for Financial Integrity: Design and implement robust idempotency patterns and distributed locking mechanisms to ensure exactly once processing for all financial transactions.
-
High-Scale Data Ingestion: Architect metering and rating engines capable of processing high-cardinality usage data, supporting complex tiered and usage-based billing models.
-
Ecosystem Integration: Build and maintain scalable, secure integrations with critical ERP and payment platforms, including NetSuite, Stripe, Zuora, and Chargebee.
-
Observability & Reliability: Establish world-class standards for performance, monitoring, and alerting across our financial stack, ensuring high availability and rapid incident resolution.
-
Force Multiplication: Act as a mentor and technical guide for our senior engineering team, conducting deep architectural reviews and authoring Architectural Decision Records (ADRs) to steer our long-term roadmap.
Your Technical Toolkit
-
Experience: 10+ years of building and scaling reliable backend systems, with a focus on financial or high-transaction platforms.
-
Modernization Expertise: A proven track record of successfully migrating legacy monoliths to modern service-based architectures (experience with PHP refactoring is a significant asset).
-
Cloud Architecture: Deep proficiency in Azure (preferred), AWS, or GCP, with hands-on experience in Kubernetes, Terraform, and serverless compute.
-
Domain Knowledge: Solid understanding of global financial complexities, including multi-currency handling, tax automation, and revenue recognition standards.
-
Security & Compliance: Practical experience implementing PCI, SOC2, and GDPR standards, with a focus on secure authentication (OAuth 2.0, JWT).
-
Communication: Exceptional ability to translate complex business needs from Finance and Operations into scalable, elegant technical designs.
Why You’ll Thrive Here
-
Total Autonomy: You will define the technical vision and lead the migration roadmap without the friction of traditional corporate red tape.
-
Tangible Impact: Your work will directly influence how value moves across borders for our global enterprise clients.
-
Remote Excellence: We are a 100% remote-first company that values deep work, asynchronous communication, and results over presence.
-
Continuous Growth: We provide a dedicated budget for conferences, certifications, and advanced technical training.
