Principal Engineer / Architect

Avalara is building the worlds 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 & 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 you’ll do

• Champion AI-accelerated engineering

  (code assist, test generation, runbook/diff summarization) to improve productivity, quality, and time-to-value.

• Own 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.

• Raise the bar on quality & operability:

  instrument connectors for observability (metrics, tracing, structured logs), establish golden signals, and drive 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 pragmatic build-vs-buy choices (SDK vs. iPaaS).
• Model integration workflows, error handling, and authentication patterns aligned to 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.
