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
