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.

• Work that matters. Our mission is to build a digital world that is secure, accessible and inclusive for everyone. From fighting fraud to making online services easier and safer to use, your work will have a real impact on how people experience trust online.

• Celebrating your big moments. We are proud to support you through life’s biggest journeys with dedicated financial bonuses for both marriage and welcoming a new baby to your family.

• Team offsites. Sometimes just Slack is not enough. That is why we meet in person a few times a year. Trips are fully covered, so you can meet, collaborate, and recharge together.

• Getting you set up. We make sure you have access to the tools and hardware you need to do your work well.

• Friendly by design. Our logo is a dog for a reason. We keep things human, open and kind. We welcome individuality, quirks and different perspectives, because that is what makes our work smarter and more fun.
