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

• Integrate generative-AI APIs and tooling: prototype, productionize, and monitor features using providers such as OpenAI, Anthropic, or Bedrock; orchestrate prompts/agents via LangChain or bespoke frameworks; enforce data-privacy guardrails.
• Champion engineering best practices: CI/CD with GitLab Actions, infrastructure-as-code (Terraform/CDK), automated testing, SLO/SLA ownership, and cost optimization.
• Mentor and collaborate: pair on tricky problems, review PRs with empathy, and partner with product, design, and ML teams to ship valuable experiences.

What You’ll Need To Be Successful

• Minimum of 4 years work experience building and operating production backend systems
• Minimum of 4 years knowledge of AWS primitives (VPC networking, IAM, security, observability, billing) and experience migrating or operating workloads across multiple cloud providers
• Proficiency in one or more backend languages (TypeScript/Node.js, Go, Python, Java) and comfort working full-stack when needed
• Hands-on experience calling or hosting generative-AI models (OpenAI, Bedrock, Vertex, Hugging Face) with understanding of prompt design, token costs, rate limits, and basic RAG patterns
