Description

POS-26083 About the team The A&B org owns the central customer-facing hub for subscription and billing management, powering over $3 billion in annual recurring revenue. While many teams touch billing, A&B is responsible for making Account & Billing the single destination where customers understand what they have, manage their subscription, and take action. The Account & Billing Integrations team focuses on the backend foundations that power these experiences: reliable services, data models, and integrations that enable accurate billing, invoices, subscription changes, usage comprehension, and seamless upgrade paths across the broader billing journey. Why this role matters A successful Senior Software Engineer on the Account & Billing Integrations team will build and evolve the backend systems that make it easy for customers to understand bills and usage, reduce support dependency by expanding self-service coverage, and enable cross-functional programs that simplify complex subscription journeys. You’ll work end-to-end with collaboration from frontend and product partners. What you’ll do • Own major backend domains and services that power the Account & Billing hub—APIs, workflows, data models, and integrations—delivering high-quality, reliable, and secure systems. • Align product, design, frontend, and go-to-market partners to solve end-to-end customer problems (e.g., subscription changes, billing comprehension, seat management, policy-bounded self-service). • Ship scalable, maintainable backend code (e.g., Java services), with attention to reliability, performance, observability, testing, and failure modes. • Translate customer pain points and data into concrete backend improvements that reduce friction (e.g., delta billing, marketing contacts limits, entitlement/plan changes, invoice accuracy). • Expand self-service capabilities by building backend workflows and guardrails so more billing actions are available without human intervention, while ensuring changes stay within policy bounds. • Mentor and raise the bar for other engineers on the team through code reviews, pairing, and shared technical ownership. • Contribute to backend architecture: service boundaries, data consistency, eventing, and safe rollout strategies for enterprise and SMB customers. • Measure outcomes and iterate: partner with PM and analytics to set success metrics, instrument services/APIs, and act on feedback. What we’re looking for • Strong backend experience (typically 5+ years) building production services (Java or similar), including API design and operational ownership. • Deep product sensibility: you can reason about end-to-end customer journeys, edge cases, and how backend behaviour impacts customer comprehension and business outcomes. • Experience delivering end-to-end features and owning backend surface areas (services, APIs, workflows, data migrations, instrumentation, rollout). • Proven ability to lead cross-team efforts and influence without formal authority. • Solid engineering fundamentals: testing, performance, reliability, observability, security/privacy, and CI/CD. • Excellent collaboration and communication skills — you’ll work closely with PMs, designers, frontend engineers, customer-facing teams, and stakeholders. • Comfortable working in a fast-moving environment and mentoring less-experienced engineers.
