Junior Test Automation Engineer

Our requirements

• Have practical experience or strong foundational knowledge of at least one programming language used in test automation: Java, Kotlin, Python or JavaScript/TypeScript.
• Know at least one automated testing framework (e.g., JUnit, TestNG, Kotest, pytest, or similar) and understand the basics of writing maintainable tests (assertions, test data, setup/teardown).
• Understand HTTP and REST APIs (methods, status codes, headers, JSON) and can test them with tools like Postman or libraries like REST Assured.
• Have a basic understanding of databases (SQL) and how backend systems process and persist data.
• Know the fundamentals of software testing: test levels, test design techniques (e.g., equivalence partitioning, boundary values), and how to write clear bug reports.
• Are comfortable with Git and the basics of working with a code repository (branches, pull requests, code review).
• See manual API/backend testing as the best way to understand a service before you automate it.
• Have a keen eye for detail and think about the whole system and data flow, not just a single feature.
• Want to be proud of the code you write, are open to feedback, and are willing to share your knowledge.
• Communicate well in a team, ask questions, and act as a "customer ambassador" for the product.
• Know English and Polish at B2 level or higher.

Optional

• Experience working in a microservices environment (understanding service-to-service communication, contracts, and asynchronous messaging).
• Experience using AI coding agents (e.g., Codex, Claude Code, OpenCode, GitHub Copilot) to speed up writing and reviewing tests, along with a critical approach to verifying their output.
• Experience with performance, contract, or E2E tests (e.g., Gatling/k6, Pact, Playwright).

Your responsibilities

• Power major promotions: Join to the team behind campaigns like Black Week and Allegro Days, and programs such as Best Price Guarantee across all Allegro markets.
• Work with experienced engineers: Build automated tests alongside a skilled team, helping our services handle major traffic peaks reliably.
• Keep quality high: Catch regressions early and improve the reliability, performance and data integrity of our services.

About the project

#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. We create solutions we love (and can) to talk about!
