Junior Software Development Engineer in Test

Overview

Stampin’ Up! is seeking a Junior Software Development Engineer in Test (SDET) to join our high-performing QA team. This role is perfect for someone early in their career who’s passionate about automation, excited to learn modern testing tools and frameworks, and ready to grow in a fast-paced Agile environment.

You’ll help design and build automated test coverage for cloud-native, microservices-based applications—while learning new systems, CI/CD pipelines, and AI-assisted testing tools along the way. It’s a role that balances learning and delivery, and we’re here to support you as you grow.

This position works closely with developers, product owners, and fellow QA teammates to ensure we’re delivering high-quality, reliable software that supports creativity at scale.

• Partner with product owners and team members to identify features that need automated test coverage
• Design, develop, and maintain integration and service-level automated tests for key workflows
• Create and contribute to automated tests using C#, JavaScript, or Type Script, with frameworks like Playwright
• Collaborate with developers to troubleshoot test failures and improve product quality
• Support testing in a cloud-native, containerized environment using Kubernetes and microservices
• Use AI-assisted tools where appropriate to improve test generation, debugging, and workflow efficiency
• Contribute to continuous improvement within the Agile software development lifecycle
• Learn, grow, and adapt as our systems and technologies evolve

This role comes with exciting challenges—and we want to be upfront about them:

• Balancing learning with delivery:
  You’ll be learning new tools, systems, and frameworks while still contributing meaningful test coverage
• Understanding complex systems:
  Our cloud-native, microservices architecture adds complexity to test design, data setup, and troubleshooting
• Collaboration & communication:
  You’ll work closely with developers and cross-functional partners in a highly collaborative Agile environment

A strong learning mindset, curiosity, and openness to feedback will be key to thriving here.

• Bachelor’s degree in Computer Science or equivalent practical experience
• 0–2+ years of experience in QA, software testing, or automation (internships and projects welcome!)
• Familiarity with programming in C# or another modern language
• Exposure to automated testing in code (preferably .NET 5+ / .NET Core)
• Understanding of object-oriented programming fundamentals
• Strong attention to detail and eagerness to learn new technologies
• Basic experience with relational databases and SQL for test validation

• Experience with Agile/Scrum and continuous delivery practices
• Exposure to RESTful API testing (Postman or similar tools)
• Interest in AI-assisted coding or testing tools (Git Hub Copilot, Cursor, etc.)
• Familiarity with Azure, AWS, or GCP
• Knowledge of CI/CD tools like Azure Dev Ops or Git Hub Actions

• An awesome benefits package
• A Friday dress code every day of the week
• Flexible schedules with every other Friday off
• Generous paid personal time off and holidays—because work-life balance matters
• Tuition assistance and 401(k) programs
• Extreme crafting experiences (yes, really )
• A culture that’s hardworking, humble, hungry to learn—and genuinely kind

If you’re curious, motivated, and excited to grow your skills while helping power creativity through reliable technology, we’d love to hear from you.
