Sr Software Dev Engineer, AWS Invoicing Global Tax & Compliance

We are seeking a Lead Engineer to own the technical vision and delivery of AWS's Tax Profile platform—the system of record for customer entity identity, tax registration, and multi-jurisdiction compliance configuration. This role is responsible for transforming a critical billing infrastructure component into a scalable, multi-tenant platform that supports complex enterprise customers with global tax obligations across multiple entities and jurisdictions. You will lead architecture decisions, drive engineering execution, and partner closely with product, tax compliance, and dependent platform teams to deliver capabilities that directly unblock AWS's largest strategic customers and international expansion.

Key job responsibilities

• **Technical leadership and architecture**: Own the system design and long-term technical vision for Tax Profile, evolving it from single-entity storage to a multi-persona, multi-jurisdiction platform supporting complex enterprise configurations.
• **Multi-jurisdiction capability delivery**: Design and deliver features for multi-tax-registration management, jurisdiction-specific document collection and validation, and entity resolution logic that scales across regulatory regimes.
• **Platform abstraction design**: Build scalable APIs and data models that decouple tax identity management from specific tenants or use cases—enabling downstream services (tax calculation, invoicing, e-invoicing, control plane) to consume Tax Profile as a platform.
• **Cross-team technical integration**: Partner with Control Plane, Invoice Configuration, Tax Calculation, and Marketplace teams to define interfaces, resolve dependency bottlenecks, and ensure Tax Profile capabilities ship ahead of downstream consumers' timelines.
• **Enterprise customer unblock**: Deliver capabilities that directly address complex billing requirements for strategic enterprise customers with multi-entity, multi-jurisdiction tax obligations.
• **Engineering excellence**: Establish technical standards for the team including code quality, operational readiness, testing strategy, and scalability patterns. Mentor engineers and raise the technical bar.
• **Operational ownership**: Ensure Tax Profile operates with high availability and low-latency at scale, owning operational metrics, on-call excellence, and incident response for a system that sits in the critical path of billing.
• **Technical debt reduction**: Identify and systematically retire country-specific implementations in favor of generalized, configurable solutions that reduce per-country engineering effort.

Basic Qualifications

• 5+ years of non-internship professional software development experience
• 5+ years of programming with at least one software programming language experience
• 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
• Experience as a mentor, tech lead or leading an engineering team

Preferred Qualifications

• 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
