Principal Engineer - Connectors & Integrations

What You'll Do

Avalara is an AI-first company. We expect every engineer, manager, and to use AI to enhance productivity, quality, innovation, and customer value. AI is embedded in our workflows, and products — and success at Avalara requires embracing AI as an essential capability, not an optional tool.

Avalara is building the world's cloud compliance platform—and our Connectors / Integration team makes it work everywhere our customers do business. We build and evolve high-quality connectors between Avalara services (e.g., AvaTax and E-Invoicing and Live Reporting / 'ELR') and third-party ERPs, commerce platforms, and other SaaS systems. Avalara emphasizes an AI-first engineering culture and operates at true global scale—tens of billions of API calls and millions of returns annually—so your architectural decisions have outsized impact.

What Your Responsibilities Will Be

• You will Champion AI-accelerated engineering (code assist, test generation, runbook / diff summarization) to improve productivity, quality, and time-to-value.
• Lead the integration architecture for connectors that link Avalara services (AvaTax, ELR etc) with major ERPs (e.g., SAP, Oracle, Microsoft Dynamics, NetSuite) and commerce platforms (e.g., Shopify, Adobe Commerce / Magento, WooCommerce), ensuring reliability, security, and great developer experience.
• Define canonical patterns (auth, retries / idempotency, versioning, webhooks / eventing, rate limiting, back-pressure) and enforce them across connector codebases.
• Lead cross-functional design with Product, Partner, Security, and SRE to translate business flows and regulatory needs into scalable integration contracts and SLAs.
• Improve on quality & operability : instrument connectors for observability (metrics, tracing, structured logs), establish golden signals, and bring incident post-mortems to closure.
• Mentor and multiply multiple teams as a hands-on technical leader—perform deep design reviews, pair on complex threads, and guide build-vs-buy choices (SDK vs. iPaaS).
• Model integration workflows, error handling, and authentication patterns in consideration of platform and regional requirements.
• Ensure seamless data flow and synchronization between systems, minimizing latency and ensuring data integrity for an ever-growing client-base and increasing data volumes.
• You will report to the Senior Director.
