Company Description
Atomic Spain is the European tech and data hub of Atomic Growth, a global AI-driven e-commerce and SaaS platform automating Amazon store management at scale. Our team builds autonomous agents that optimize pricing, advertising, inventory, and operations - powered by real-time data from hundreds of active storefronts.
Role Description
We are looking for a meticulous QA Engineer based in Malaga, Spain to join our distributed engineering team. You will play a critical role in ensuring that when our customers look at their profit margins or ad spend, the numbers are 100% accurate, when an ai agent issues a recommendation it's valid based on its available data.
You won't just be testing if a button works, you will be testing business logic. You will verify that our data pipelines, financial calculations, and ad-attribution models are correct. You will work closely with Product Managers and Developers to ensure our analytics dashboards are reliable and fast.
Key responsibilities
* Test Planning & Execution: Design, implement, and execute test plans for our web application, focusing on Data Integrity, Model predictions, Agent recommendations etc...
* Data Validation: Compare our data with external sources (Seller platforms, 3rd party SaaS etc...) making sure it is coherent
* Logic Verification: Manually and automatically test complex mathematical formulas (e.g., Gross Profit, ROAS, TACoS) to ensure accurate P&L reporting.
* Automation: Contribute to our automated testing framework (Github Actions/Playwright/Selenium) to cover critical regression paths.
* Bug Hunting: Identify, record, and track bugs using Jira. Prioritize issues based on impact on financial accuracy and user experience.
* Cross-Functional Work: Collaborate with an international team of developers to reproduce issues related to time zones, currency conversions, and large datasets.
Requirements
* Experience: 3+ years of experience in Software Quality Assurance (Web & SaaS).
* Data Proficiency: Strong knowledge of SQL. You must be comfortable querying databases to validate test results (e.g., checking if the Profit calculation matches the Revenue minus Expenses in the DB).
* Technical Stack: Experience with API testing (Postman, REST) and familiarity with CI/CD pipelines (Jenkins, GitHub Actions).
* Automation Basics: Experience writing or maintaining automated scripts (JavaScript/TypeScript or Python preferred).
* Language: Fluent in English. We are an international company, and all documentation/meetings are in English.
* Mindset: Extreme attention to detail. A rounding error in our software costs our clients money.
Nice to have
* Domain Knowledge: Experience working with Amazon Seller Central, Amazon SP-API, or generally in the E-commerce/AdTech space.
* Financial/Ad Experience: Understanding of concepts like PPC, CPC, ACOS, VAT, and COGS (Cost of Goods Sold).
* Math/Stats Background: A degree or background in mathematics, statistics, or finance is a huge plus.
