Senior QA Engineer — Desktop Team

Who we're looking for

We are seeking a Senior QA Engineer to join our R&D Team (250+ people: developers, QA engineers, designers, technical support engineers, DevOps engineers, and product managers). TaxDome is the leading all-in-one practice management platform for tax, bookkeeping, and accounting firms. Documents are at the heart of TaxDome — they are the central entity around which the entire platform is built.

Our Desktop Application is a critical part of the product ecosystem. We're building a brand-new Desktop App v4 — a cross-platform application on a shared .NET codebase that runs on both Windows and macOS. We need someone who combines a product mindset with strong automation expertise — a quality engineer who understands the business, can analyze requirements, build and own the automation framework, and enable the entire team to deliver with confidence.

This is not a web QA role. We need someone with deep experience testing desktop applications — someone who understands the complexity of native OS environments, platform-specific behaviors, and the challenges that come with shipping software that runs directly on users' machines. You will shift quality left, close technical debt in test coverage, and establish a robust automated safety net as we scale Desktop App v4.

About the Tax Preparation Cluster

The Tax Prep Cluster is part of TaxDome's core platform — the back-office hub for accounting firms. We manage the end-to-end tax preparation process, including:

• Intake Flow — smart document & data collection (questionnaires, checklists, automation)

• Tax Preparation Flow — validation and secure transfer to external tax systems

• Delivery Flow — finalized returns, e-signatures, and payments

Each flow uses AI-based document handling and LLM assistants to reduce manual work and improve accuracy. Our goal is to make the tax preparation experience seamless, automated, and AI-driven.

About the Desktop Team

The Desktop Team is responsible for TaxDome's native desktop application — a key touchpoint for thousands of accounting professionals who rely on it daily for document management, printing, scanning, and seamless integration with the TaxDome platform.

We are currently delivering Desktop App v4 from the ground up, with a focus on:

• Cross-platform stability — unified experience across Windows and macOS

• Print & scan workflows — deep OS-level integration with printers, scanners, and PDF rendering

• Document handling — reliable file sync, PDF processing, and local-cloud data exchange

• Gradual rollout — phased releases with quality gates at every stage

Technology Stack

• Application: .NET (shared cross-platform codebase)

• Automation: .NET, WinAppDriver, platform-specific adapters

• Scripting: PowerShell, Bash

• CI/CD & VCS: GitLab CI

• Test Management: QASE

• Project Management: Jira (Agile/Scrum)

• Infrastructure: Docker, AWS

Your Responsibilities

• Take part in all team ceremonies (daily standups, sprint planning, refinement, retrospectives, bug retros, tech retros) to advocate for quality early in the process

• Analyze requirements before development — participate in refinement sessions, clarify acceptance criteria, and design test scenarios that cover all business requirements

• Perform exploratory, functional, regression, and compatibility testing across diverse Windows and macOS environments — different OS versions, hardware configurations, printer/scanner setups, antivirus software, and remote desktop environments (RDP, Citrix, VDI)

• Design and execute the test strategy based on the Testing Pyramid approach: unit, component, integration, and E2E levels

• Develop and maintain the automation framework in .NET together with the SDET — for UI, integration, and component-level testing (WinAppDriver and platform-specific adapters)

• Integrate automated suites into GitLab CI as quality gates — triage failures, track flaky tests, and manage automation technical debt

• Develop supporting tools and scripts in PowerShell/Bash for data setup, environment configuration, and log collection

• Maintain test documentation in QASE — link cases to automation and ensure transparency of coverage

• Collaborate with Dev, DevOps, and the SDET within the team to include smoke, stability, and regression checks in CI pipelines

• Act as a Quality Coach — mentor developers on QA best practices, testability, and clean test architecture principles

• Drive bug retrospectives and root cause analysis to reduce rework and prevent recurring defects

• Support gradual release processes by validating builds at each rollout stage

Our Expectations

Technical:

• 5+ years of QA/SDET experience, with a balanced background in both Manual and Automation Testing

• Proven experience testing desktop/thick-client applications on Windows — understanding of OS-level behaviors, file systems, registry, installers, services, and system-level integrations

• Experience testing across multiple operating systems and their various versions (Windows 10/11, macOS versions) as well as remote desktop environments (RDP, Citrix, VDI) — awareness of platform-specific quirks, UI rendering differences, and environment-dependent issues

• Hands-on experience in C# / .NET — ability to read, understand, and write code for test automation

• Proven experience building and maintaining desktop automation frameworks (WinAppDriver, Appium for Windows, or similar)

• Understanding of cross-platform testing challenges (Windows/macOS)

• Strong grasp of OOP, test architecture, and design patterns (Page Object, data-driven, modular layers)

• Solid understanding of the Testing Pyramid and how to apply it in practice

• Scripting experience in PowerShell and/or Bash for automation and environment management

• Familiarity with CI/CD (GitLab) and integration of automated tests into pipelines

• Hands-on experience working with requirements, acceptance criteria, and test design in a TMS

Soft:

• Product mindset — comfortable working with requirements, analyzing business logic, and translating them into test scenarios

• Strong ownership, clear communication, and a proactive approach to product quality

• Collaborative communicator with developers, product managers, and DevOps

• Analytical, ownership-driven, and focused on long-term test stability

Preferred

• Experience with PDF rendering/printing workflows

• Experience setting up or significantly improving QA processes in a team

• Basic understanding of non-functional testing (performance, security)

• Experience with performance profiling and test observability tools

• Interest and experience in building AI agents and integrating them into daily workflows to enhance testing efficiency and productivity

Why TaxDome

• Cross-platform impact: help deliver a unified desktop experience for Windows and macOS users

• Full automation focus: goal is complete automation coverage and minimal manual testing

• Tech stack: .NET, WinAppDriver, GitLab CI, PowerShell, Bash — full ownership of the testing ecosystem

• Direct influence on the quality of one of TaxDome's core products, used daily by thousands of accounting firms

• Engineering culture: autonomy, collaboration with Dev and DevOps, and growth toward QA leadership or technical direction

• AI: We actively encourage experimentation with AI tools and automation of routine tasks. The company covers costs for AI tools to support experimentation and practical implementation

• Remote-friendly culture, flexible schedule, and supportive engineering environment
