Now we are looking for a QA Engineer .

At Sumsub, Quality Assurance is not a reactive "check-box" exercise; it is a proactive pillar of our product development. We are looking for a QA Engineer who operates as both a technical investigator and a product advocate. In this role, you will be responsible for ensuring the reliability of complex verification orchestrations, focusing on the "why" behind every feature to deliver a seamless and secure user experience.

Key Responsibilities

• Analytical Precision: Conduct deep-dive testing across web platforms, SDKs, and APIs. You are expected to deconstruct complex logic and identify potential edge cases before they reach production.
• Collaborative Requirement Refinement: Work directly with Developers and Product Managers to define and sharpen acceptance criteria. We value engineers who proactively identify gaps in technical specifications.
• Technical Troubleshooting: Utilize logs, database queries, and browser tools to perform root-cause analysis, ensuring that reported issues are well-documented and actionable.

Professional Profile

• Experience in Product-Centric Environments: You have a proven track record in fast-paced product companies. We specifically value experience gained in agile tech environments over traditional corporations.
• Self-Directed Problem Solving: You possess the ability to navigate ambiguity. You can explore a new feature, consult documentation, and establish a testing strategy independently without high-level supervision.
• Strong Communication Ethics: In our remote-first culture, proactive communication is essential. You are comfortable initiating discussions, asking clarifying questions in team channels, and advocating for quality standards even under tight deadlines.
• Analytical Mindset: You enjoy the process of exploring and "breaking" systems to make them stronger and have a natural curiosity for how complex backend systems interact with user-facing interfaces.

Technical Toolkit

• API Testing: High proficiency with tools such as Postman and Charles Proxy.
• Observability & Data: Experience with browser DevTools, log analysis (e.g., Sentry, Kibana), and SQL for data verification.
• Platform Versatility: Competence in testing across iOS, Android, and various web environments.
• Test Automation (Optional): While manual proficiency and analytical skills are the priority, experience with or an interest in test automation frameworks is considered a professional asset.

The Sumsub Culture Fit

• Autonomy over Hierarchy: You thrive in a flat organizational structure where expertise is valued over titles.
• Curiosity & Growth: You stay updated on industry trends and are always looking for ways to improve internal QA processes.
• Transparency: You believe in honest, direct feedback and have the professional integrity to signal when quality does not meet our benchmarks.
