Taxwell is a leading digital tax filing platform formed in 2022 from the combination of Drake Software® and TaxAct®. These two longstanding organizations offer customers professional and do-it-yourself digital and downloadable products that are easy-to-use, best-in-class technology, and provide unparalleled customer support. Taxwell brands are a trusted solution for all users including those with complex tax returns. We strive to attract and retain candidates who exemplify our values: performance, perseverance, progress and partnership. Taxwell is an organization of forward thinkers looking to add industry experts to our growing team.

We’re seeking a Principal Software Engineer to lead key initiatives across our authentication and early customer experience surfaces. These systems are central to how customers first engage with our platform and demand solutions that are scalable, performant, and secure.

You’ll lead engineers across multiple teams by setting direction, driving execution, and mentoring not through direct line management, but through hands-on technical leadership. You will lead through influence, technical vision, and delivery, partnering with senior engineers, product, and design leaders to drive initiatives forward. This role requires someone who has already operated at the principal level, owning large-scale systems and leading multi-team engineering efforts that materially impacted the business.

You’ll be responsible for defining architecture, solving deeply technical and ambiguous problems, mentoring other senior engineers, and serving as a technical bar-raiser across the organization. Your work will span from hands-on implementation to strategic design and technical decision-making.

Responsibilities:

  • Lead critical engineering initiatives that span multiple teams and impact core customer experiences, including our authentication platform and onboarding flows.
  • Own technical architecture and roadmap decisions for key areas of the platform, working from first principles to drive scalable, reliable, and maintainable solutions.
  • Collaborate across engineering, product, and design to shape systems that align business and user needs.
  • Mentor and guide other senior engineers through code and design reviews, informal collaboration, and strategic direction-setting.
  • Write production-grade code regularly exploring and validating new technical approaches, modernizing legacy services, or building shared tooling.
  • Actively participate in defining and evolving our engineering standards, CI/CD practices, observability frameworks, and security posture.
  • Help integrate AI-assisted development tools into engineering workflows, balancing productivity with code quality and team learning.

Qualifications:

  • 10+ years of experience in software engineering, including at least 5 years operating at the Staff, Principal, or Architect level in high-scale environments.
  • Proven record of leading large, complex technical initiatives that required coordination across multiple teams and functions.
  • Deep experience with C#/.NET and modern frontend frameworks (Vue.js preferred), or strong capability to quickly ramp up in both.
  • Expertise in AWS, Kubernetes, distributed systems, and modern infrastructure practices.
  • Strong grasp of architectural patterns: APIs, service decomposition, asynchronous systems, CI/CD, and secure development.
  • Hands-on experience with web-scale production environments and a bias toward pragmatic solutions.
  • Exceptional communication skills—you can articulate technical strategy clearly to engineers and cross-functional stakeholders alike.
  • Operate with an ownership mindset: you define problems, chart a path forward, and bring others with you.
  • Experience with authentication, identity, or user onboarding flows is a strong plus.

Bonus:

  • Familiarity with AI-assisted software development workflows and tools like GitHub Copilot, Cursor, or Claude Codex.

At Taxwell, we believe our work benefits from the diverse perspectives of our employees. As such, Taxwell welcomes and celebrates diversity and inclusion and is committed to equal opportunity employment.
