Greater Madrid Metropolitan Area, España Atomic Growth A tiempo completo

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 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.
