Test Automation Engineer 1

Junior • Hybrid

10,700 - 14,900 PLN/mo

Poznan, Poland

Job Description:

Join xLab, an internal unit at Allegro with the independence of a startup and the impact of a market leader. Our mission is to build a world-class Design System, and we need a Test Automation Engineer to help us scale our quality through smart automation and AI-driven workflows. We aren't a traditional team; we co-create the tools and standards that define how Allegro’s interfaces look and feel.

 

You’ll be responsible for the cross-platform integrity of our native web and mobile components. By blending manual exploration with modern automation frameworks and AI tools, you’ll ensure our UI is robust across iOS, Android, and Web. If you’re looking for a role with high ownership where you can influence the engineering culture of a major tech organization, this is it.

 

Important things for you:

  • Flexible working hours in the hybrid model (4/1) - working hours start between 7:00 a.m. and 10:00 a.m. We also have 30 days of occasional remote work.

  • The salary range for this position depending on the skill set is as follows (contract of employment, tax-deductible cost):

    • PLN 10 700 - 14 900

    • Annual bonus based on your annual performance and company results.

  • Our team is based in Poznań.

Your main responsibilities:

  • Blending manual exploratory testing with automation to ensure a high-quality experience for our cross-platform Design System across iOS, Android, and Web.

  • Performing exploratory and validation testing to deeply understand new UI components and their various states before you start writing code for them.

  • Creating and maintaining automated UI tests, focusing on the frontend and component-level interactions without the need for backend dependencies.

  • Participating in Visual Regression Testing to ensure pixel-perfect implementation and consistency across different platforms, browsers, and screen sizes.

  • Utilizing AI-powered tools (e.g., LLMs, GitHub Copilot) to accelerate test script creation, brainstorm test cases, and optimize your daily workflow.

  • Collaborating closely with frontend developers and UX/UI designers to introduce and implement component specifications and accessibility (a11y) requirements.

  • Analyzing test results and tracking UI defects, clearly reporting any visual or functional issues in our issue-tracking system.

  • Contributing to the continuous improvement of quality processes and methodologies.

This offer is for you if:

  • You have basic practical experience (from academic projects, bootcamps, or a personal portfolio) with modern frontend or mobile automation frameworks like Playwright, Cypress, or Appium.

  • You see manual testing as the best way to truly understand a component before you start writing code to automate it.

  • You understand how web and mobile interfaces are built (you’re comfortable with the DOM, CSS selectors, and mobile view hierarchies).

  • You are eager to leverage AI tools in your daily QA workflow to work smarter and level up your technical skills faster.

  • You possess a "pixel-perfect" mindset and a keen eye for detail—you’re the person who spots minor visual misalignments, wrong typography, or incorrect color tokens.

  • You are familiar with the GIT version control system and have a basic understanding of how CI/CD pipelines work.

  • You communicate clearly and logically, making it easy for others to understand UI issues, and you have a strong drive to grow in a specialized frontend environment.

  • You have a positive attitude towards teamwork and at the same time can work independently.

What's in it for you:

  • Well-located offices (with e.g. fully equipped kitchens, bicycle parking, terraces full of greenery) and excellent work tools (e.g., raised desks, ergonomic chairs, interactive conference rooms).

  • A 16" or 14" MacBook Pro or corresponding Dell with Windows (if you don't like Macs) and all the necessary accessories.

  • A wide selection of fringe benefits in a cafeteria plan - you choose what you like (e.g., medical, sports or lunch packages, insurance, purchase vouchers).

  • English classes that we pay for related to the specific nature of your job.

  • A training budget, inter-team tourism (see more here), hackathons, and an internal learning platform where you will find multiple trainings. 

  • An additional day off for volunteering, which you can use alone, with a team, or with a larger group of people connected by a common goal. 

  • Social events for Allegro people - Spin Kilometers, Family Day, Fat Thursday, Advent of Code, and many other occasions we enjoy.

 

And that's just the beginning! You can read more about the benefits here.

 

#goodtobehere means that:

  • You will join a team you can count on - we work with top-class specialists who have knowledge- and experience-sharing in their DNA.

  • You will love our level of autonomy in team organization, the space for continuous development, and the opportunity to try new things. You get to choose which technology solves the problem and you are responsible for what you create.

  • You will value our Developer Experience and the full platform of tools and technologies that make creating software easier. We rely on an internal ecosystem based on self-service and widely used tools such as Kubernetes, Docker, Consul, GitHub, and GitHub Actions. Thanks to this, you can contribute to Allegro from your very first days on the job. 

  • You will be equipped with modern AI tools to automate repetitive tasks, allowing you to focus on developing new services and refining existing ones (also leveraging AI support).

  • You will create solutions that will be used (and loved!) by your friends, family and millions of our customers.

  • You will meet the Allegro Scale, which starts with over 1000 microservices, an open-source data bus (Hermes) with 300K+ rps, a Service Mesh with 1M+ rps, tens of petabytes of data, and production-used machine learning. 

  • You will become part of Allegro Tech - We speak at industry conferences, cooperate with tech communities, run our own blog (it's been over 10 years!), record podcasts, lead guilds, and we organize our own internal conference - the Allegro Tech Meeting.
