Job summary

Avalara is accelerating delivery of AI-enabled capabilities across our compliance platform to improve customer experience, increase engineering velocity, and scale global operations efficiently. As a Technical Lead, you will join a globally distributed team to architect distributed systems and embed applied AI into our core products.

You will sit within the E-invoicing and Live Reporting (ELR) team and reports to a Director of Engineering.

Qualifications

• B.S. in Computer Science or Engineering with 12+ years of professional software engineering experience.
• Hands-on experience building scalable APIs and services with Java or .NET (C#) and maintainable frontend applications with React (TypeScript).
• Experience with distributed systems, RESTful/GraphQL APIs, system performance trade-offs, load balancing, and high availability engineering.
• Experience with AWS (Azure or GCP welcome), Infrastructure as Code (Terraform), CI/CD pipelines (e.g., GitLab), Docker, and Kubernetes.
• Experience with relational and NoSQL databases and automated testing strategies.
• Demonstrated, measurable impact from hands-on AI usage that improved business or engineering outcomes (casual AI usage is insufficient).
• Experience with LLMs and AI architectures, with experience designing and implementing agentic AI systems using frameworks like LangGraph, Semantic Kernel, AutoGen, or CrewAI.
• Deep knowledge of Retrieval-Augmented Generation (RAG), Vector databases, prompt engineering best practices, and model selection trade-offs.
• Strong understanding of AI security risks (prompt injection, data leakage) and data privacy/compliance requirements (e.g., GDPR).

Responsibilities

• Architect and deliver scalable, secure backend and frontend systems that support our global compliance platform.
• Lead technical design discussions and influence architectural decisions, collaborating cross-functionally to solve complex technical challenges.
• Increase development efficiency by embedding AI-assisted coding, testing, documentation, and architectural exploration into daily workflows.
• Deliver AI-enabled product features that enhance automation, data processing, and customer-facing intelligence.
• Improve deployment frequency, automated test coverage, and code quality through CI/CD and engineering best practices.
• Reduce production incidents and improve system observability through thoughtful architecture and proactive monitoring.
• Raise team performance standards through active mentoring, peer feedback, and maintaining high standards of accountability.
