- 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

- 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
