QA engineer (AI and Browser Automations)

About the Product & Team

​Our client is an innovative, fast-growing tech startup developing a next-generation AI agent for autonomous browser and web workflow automation. The platform leverages modern LLMs to dynamically inspect web interfaces, generate resilient Playwright automation scripts, and execute complex, repetitive browser tasks for businesses across the US and Europe.

​You will join a lean, engineering-driven team focused on making client automations and system integrations seamless, stable, and accurate.

​Role Overview

​We are looking for a detail-oriented Integration QA Engineer to validate, test, and maintain integrations between our AI browser automation platform and external customer environments. This role is primarily focused on manual integration testing, payload validation, and data verification.

​A core expectation of this role is using modern AI developer tooling (such as Claude Code, Cursor, or similar assistants) to inspect codebases and independently apply small configuration adjustments, data mapping fixes, or parameter updates directly in the JavaScript code.

​

Key Responsibilities

• ​Integration & Workflow Testing: Test end-to-end integration scenarios, ensuring data flows accurately between client platforms, third-party services, and our automation agent.
• ​Payload & Mapping Verification: Identify and isolate data mismatches (e.g., verifying that expected fields, parameters, and payloads match what the platform sends/receives).
• ​AI-Assisted Configuration & Quick Fixes: Leverage AI coding tools (such as Claude Code) to navigate the codebase, apply minor configuration adjustments, update field mappings, and patch simple JavaScript snippets.
• ​Edge-Case Identification: Spot anomalies in agent executions, broken integration hooks, or inconsistent DOM/API responses.
• ​Defect Reporting & Collaboration: Document edge cases, create clear reproduction steps, and coordinate with the engineering team to resolve deeper platform bugs.

Requirements

• ​Manual QA Experience: Solid background in functional, regression, and integration testing for web platforms and APIs.
• ​AI Tooling Fluency: Strong, hands-on experience using modern AI-assisted coding tools (e.g., Claude Code, Cursor, Claude, ChatGPT) for code navigation, debugging, and task automation.
• ​Basic JavaScript Literacy: Ability to read and understand basic JavaScript / TypeScript (navigating JSON structures, config files, basic functions, and variable mappings).
• ​API & Data Fundamentals: Confident understanding of REST APIs, webhooks, JSON payloads, and browser developer tools (Network/Console tabs).
• ​Self-Sufficiency: A proactive mindset to diagnose issues and make minor code/config fixes independently rather than just logging tickets.
• ​Communication: Upper-Intermediate (B2+) to Fluent English for written documentation and team communication.

​Nice to Have

• ​Familiarity with browser automation concepts or tools (Playwright, Puppeteer).
• ​Experience working in early-stage, fast-paced startup environments.
• ​Basic understanding of prompt engineering and LLM behavior.

We OFFER:

• ​A fast-paced, highly professional, international team environment with a flat structure and rapid decision-making.
• ​Competitive compensation packages commensurate with your background and product portfolio.
• ​Flexible, remote-first workflow optimized for seamless global alignment.
• Medical Insurance in Ukraine and a Multisport program in Poland.
• Offices in Ukraine (Kyiv, Kharkiv) and Poland (Wroclaw) or Remote.
• Paid vacation, sick leave, and official holidays.
• Legal & Accounting services.
• The company provides all necessary equipment.
• English classes and Education reimbursement.
