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.
