Résumé du poste

Allegro Sp. z o.o. is seeking a test automation engineer to build automated tests and help our services handle high traffic.

You will work with Java, Kotlin, Python or JavaScript/TypeScript and use frameworks like JUnit, TestNG, Kotest, or pytest, testing HTTP/REST APIs with Postman or REST Assured. You’ll ensure data integrity and collaborate to improve reliability in a hybrid Warsaw team. The role emphasizes API/backend testing, familiarity with SQL, and Git workflows.

Qualifications

• Experience with at least one programming language used in test automation (Java, Kotlin, Python or JavaScript/TypeScript).
• Familiarity with one automated testing framework (JUnit, TestNG, Kotest, pytest, etc.).
• Understanding of HTTP/REST APIs and testing tools like Postman or REST Assured.
• Basic SQL and data handling for backend systems.
• Knowledge of software testing fundamentals and test design techniques.
• Basic Git usage (branches, pull requests, code review).
• Insight into testing of services before automation.

Responsabilités

• Develop and maintain automated tests for services under high traffic, ensuring reliability.
• Test REST APIs and backend components using modern tools (Postman, REST Assured).
• Collaborate with engineers in a hybrid Warsaw team to catch regressions early.
• Contribute to data integrity, performance and quality across microservices.
• Participate in code reviews and maintain clear bug reports and test data.

Description du poste

About the job

• 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.

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.
• Annual bonus based on your annual performance and company results.
• Our team is based in Warsaw.

This is the right job for you if you:

• 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.

Nice to have:

• 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).

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