What You'll Do

This role exists to support and scale Avalara's Workday development and enterprise system integrations at a time of increasing demand, growing backlog, and critical initiative delivery. Following recent attrition, this position is essential to ensure continuity, delivery velocity, system reliability, and sustainable engineering execution across Workday and related enterprise platforms.

The Sr. Software Engineer will be responsible for delivering high-quality engineering outcomes across Workday development, integrations, automation, and enterprise system initiatives.

• Own and deliver Workday development, integrations, enhancements, and related engineering work with a focus on reliability, scalability, maintainability, and business impact.
• Contribute to high-priority engineering initiatives including AvaTax development, ELR readiness through planned SRR/ARB work, AP cutover support for Canada and the USA, and automation testing for new and existing features.
• Reduce backlog by delivering high-impact engineering work with strong prioritization, execution discipline, and ownership from requirements through production support.
• Improve system performance, stability, observability, and maintainability across Workday and related enterprise platforms.
• Build and improve automation capabilities to reduce manual effort, improve testing coverage, accelerate delivery, and reduce operational risk.
• Collaborate cross-functionally with product, finance, tax technology, PM, EIE, and engineering stakeholders to deliver business-critical outcomes.
• Support the engineering Confluence overhaul by improving documentation quality, standardizing knowledge repositories, and reducing dependency on tribal knowledge.
• Participate in code reviews, design discussions, testing strategy, release readiness, and operational support activities to ensure high-quality delivery.
• Identify opportunities to simplify complex workflows, improve engineering processes, and increase team productivity through better tooling, automation, and AI-assisted development practices.

AI Expectations (AI Bar Raiser)

Avalara is an AI-first company, and this role is expected to use AI in practical, responsible, and measurable ways to improve engineering outcomes.

• Use AI-assisted development tools to accelerate coding, debugging, test creation, documentation, and integration analysis.
• Apply AI to improve quality and speed in Workday development, automation testing, API/integration work, and troubleshooting.
• Use AI to support better documentation practices, including summarizing technical decisions, improving Confluence content, and making knowledge easier to discover and maintain.
• Identify opportunities where AI can reduce repetitive manual effort, improve developer productivity, strengthen testing, or improve operational insight.
• Quantify the impact of AI usage where practical, such as time saved, faster delivery, reduced defects, improved documentation quality, or improved support efficiency.
• Apply AI responsibly and securely, especially when working with enterprise systems, business processes, integrations, and potentially sensitive operational data.
• Share effective AI practices with the team and help raise the overall AI capability of peers through examples, documentation, and knowledge sharing.

This role is expected to demonstrate applied AI capability that improves speed, quality, insight, automation, and scale - not just casual or occasional tool usage.
