Architecting a Multi-Product Engine: Shift from a single-product tool to a self-serve platform for 10+ services, building the billing and configuration logic that allows any customer to go live without manual intervention.
Balancing Enterprise & Scale: You’ll solve the tension between bespoke "whale" account requirements and a high-volume self-serve funnel, designing abstractions that satisfy complex SLAs without sacrificing platform speed.
Modernizing while Shipping: You will strategically rebuild 6-year-old legacy systems—specifically our high-traffic session list and decision profiles—ensuring our core infrastructure stays as modern as the new features we ship.
Engineering Cross-Team Alignment: As the entry point for Identity, Fraud, and Trust teams, you’ll coordinate how their products live in the portal, ensuring architectural consistency and code quality across the entire portfolio.
Amplifying Delivery with AI: You’ll help the team scale beyond its headcount by championing AI-enhanced workflows, turning "big ambitions" into reality through smarter automation and iterative, independent delivery.

5+ years building feature-rich web applications, with real depth in modern JavaScript/TypeScript, the React ecosystem and its best practices.
You have working proficiency in back-end Node.js applications, and feel comfortable designing and maintaining REST APIs that integrate and orchestrate data from multiple internal and external services.
You have owned something end-to-end: a product area, a service, a migration. Not just contributed to it.
You have experience running services in production: on-call, monitoring/observability (e.g. Sentry, Prometheus-based SLOs), and incident handling.
You are comfortable working in legacy code without burning it all down. You know how to modernize incrementally while keeping things running.
You can hold your own in product conversations. This team sits at the intersection of billing, configuration, and customer lifecycle. You will need to understand the business problem, not just the ticket.
You are curious about AI-assisted development workflows. We are pushing hard on using AI to multiply what a small team can deliver. You don't need to be an expert, but you should be genuinely interested.
