About your Role

We are seeking a Senior Software Engineer who brings strong technical skills combined with ownership, initiative, and genuine enthusiasm for building products.

This role is ideal for someone who:

  • Takes true ownership of features end-to-end
  • Has experienced the full software lifecycle (build → deploy → maintain → iterate)
  • Is self-directed and highly autonomous
  • Is motivated to contribute to a growing product and company, not just complete tickets

This is a hands-on, high-impact IC role where you will be one of the primary U.S.-based engineers, expected to make decisions and move quickly with minimal oversight.

Your Responsibilities

      • Design, build, and maintain full-stack applications using C#, .NET, Angular, and Azure
      • Own features end-to-end (requirements → development → deployment → support)
      • Break down problems into scalable, maintainable solutions
      • Write clean, production-ready code
      • Participate in code reviews and contribute to engineering best practices
      • Collaborate closely with product and engineering teams
      • Contribute to feature-level design and architecture (not just implementation)
      • Improve CI/CD pipelines and development workflows
      • Troubleshoot and resolve issues across distributed systems

Requirements

Who You Are:

As the ideal candidate for this role, you possess:

      • Bachelor’s degree in Computer Science, Engineering, or related field (or equivalent experience)
      • 4–9+ years of software development experience (flexible based on capability)
      • Strong experience with C# and .NET
      • Experience with modern JavaScript frameworks (Angular preferred; React/Vue acceptable)
      • Experience building SaaS or cloud-native applications
      • Experience with Microsoft Azure, including:
        • Azure Service Bus
        • Azure Functions
        • Azure API Management
        • Azure SQL
      • Experience with Docker and Kubernetes
      • Familiarity with Git, CI/CD pipelines, and Azure DevOps
      • Experience with testing frameworks (NUnit, MSTest, Playwright, etc.)

It's Truly a Match If You Have:

In addition to the above, we're looking for candidates who have:

  • Experience with PDF/document generation tools (Aspose, IronPDF, iTextSharp)
  • Experience in tax technology, accounting software, or financial platforms
  • Exposure to Python or AI/ML tools
  • Experience in high-growth SaaS or startup environments

What Sets This Role Apart:

  • High Ownership: You will be one of the core U.S.-based engineers
  • Real Impact: Direct influence on product and technical direction
  • Growth Opportunity: Help scale a fast-growing SaaS company
  • Autonomy: Build, ship, and own your work end-to-end

Benefits

  • Unlimited Vacation Policy + Sick Time + Holidays
  • Paid Parental Leave
  • Fully Remote Opportunity
  • Healthcare Benefits and 401K
  • Growing Startup Culture
