Job Description

The Principal Software Engineer for the WFM team is a technical leader who shapes how the team builds software in an AI-first development environment. This role combines deep architectural judgment with product awareness, helping the team make the right decisions about what to build, how to build it, and when AI-generated output is trustworthy versus when it needs human expertise.

This role is hands-on. This person brings clarity to ambiguous problems, coaches engineers on both stack proficiency and systems/product thinking, and ensures architectural decisions serve both current needs and long-term product direction. They are a key participant in the team's AI Development Lifecycle, an operating model where product, UX, engineering, and QA collaborate in real time to define and deliver solutions together. AI-assisted development is a core part of how the team works, and we expect you to use agentic coding, spec-driven development, and AI-augmented code review in your daily workflow.

• Critically evaluating AI-generated code for correctness, performance, security, and architectural fit
• Helping define and evolve the team's AI development practices, identifying where AI accelerates delivery and where human judgment is essential

Coaching and Team Development

• Providing frequent guidance and support to other developers, including hands-on, stack-specific mentoring (C#, Angular, SQL Server, etc.)
• Coaching engineers on problem decomposition, product thinking, and architectural judgment in addition to syntax and implementation detail
• Raising the team's ability to articulate problems clearly, evaluate AI output critically, and reason about systems holistically
• Helping engineers at all levels develop the judgment to know when AI-suggested solutions will create downstream pain

Product and Process

• Participating on the agile team to estimate and groom backlog items, plan development activities, and improve the development process
• Working with business analysts to clarify requirements and debug problems
• Anticipating how architectural decisions affect the product roadmap, and proactively surfacing risks and opportunities
