Junior Software Development Engineer in Test

Stampin Up Inc•Riverton, UT

About The Position

Stampin' Up! is seeking a curious, collaborative Junior Software Development Engineer in Test (SDET) to help build quality into the products used by its demonstrators and customers. This is an engineering-focused testing role embedded in a development team, working alongside developers, business analysts, and product owners rather than in a separate QA department. The SDET will help advance the team's shift from manual testing to automation-first quality practices by building automated tests that inform release decisions, while also using exploratory and manual testing when appropriate. The role provides exposure to an interconnected e-commerce business, including ordering, payments, subscriptions, commissions, and internal business operations. Success calls for continuous learning, thoughtful communication, ownership, and sound engineering judgment, including when using AI tools.

Requirements

Bachelor's degree in Computer Science, Software Engineering, Information Technology, or equivalent practical experience.
At least 3 years of experience in software testing, test automation, or software development involving automated testing.
Experience building and maintaining automated tests with frameworks such as Playwright, Selenium, or Cypress.
Proficiency in at least one programming language, such as TypeScript, JavaScript, Python, or C#.
Strong SQL skills, including joins, aggregations, troubleshooting, and data validation.
Experience testing REST APIs and understanding modern integration patterns.
Familiarity with Git, pull requests, code reviews, and CI/CD workflows.
Ability to distinguish application issues from test failures or environment issues.
Strong analytical and problem-solving skills.
Clear verbal and written communication skills.

Nice To Haves

Experience with Playwright and TypeScript.
Experience with Azure DevOps.
Experience testing .NET applications and Microsoft SQL Server.
Experience with AI coding assistants such as GitHub Copilot, Claude Code, or similar tools.

Experience supporting e-commerce, payment processing, or order management systems.
Experience with Application Insights, logging tools, and troubleshooting distributed systems.
Experience with accessibility, performance testing, or test data management.
Experience contributing production code, not just test code.
Experience helping improve engineering tooling or automation frameworks.

Responsibilities

Demonstrate Stampin' Up!'s core values in daily work and interactions.
Partner with developers, business analysts, and product owners to understand requirements and identify quality risks early.
Design, develop, and maintain automated tests for web applications, APIs, and backend services.
Write SQL queries to validate business processes, investigate defects, and verify data integrity.
Integrate automated testing into CI/CD pipelines and improve test reliability and coverage.
Use AI tools daily to write tests, investigate failures, and speed up work.
Evaluate and validate AI-generated code and recommendations using sound engineering judgment.
Perform exploratory and manual testing when automation is not practical or sufficient.
Investigate production issues, analyze logs, and help identify root causes.
Document test results, defects, and quality risks using Azure DevOps and related tools.
