[Hiring] Strong Junior QA Manual Engineer @NineTwoThree AI Studio

Role Description

This is not a traditional QA role. Most of our products are powered by AI — meaning the system's output is intentionally non-deterministic. There's no single "right answer" to compare against. Your job is to figure out what "correct" looks like for a given business goal, build your own definition of it, and systematically verify whether the system gets there.

• Testing AI responses for data synthesis from multiple sources.
• Ensuring application of the right organizational rules.
• Verifying that the system stays within intended boundaries and does not leak information.

We'll teach you the tools and techniques. What we can't teach is how you think — and that's what we're hiring for.

Qualifications

• 1.5+ years in QA or software engineering.
• Strong understanding of QA process, methodology, and terminology (test plan, test cases, SDLC, regression).
• Experience with manual testing of web and mobile applications.
• Comfort working with REST API and browser DevTools to inspect what's actually happening under the hood.
• Upper-Intermediate English (you'll communicate with international clients daily).
• You ask "why is this the right answer?" before accepting what the screen shows you.

Requirements

• Review requirements and independently define what "correct output" looks like when none is explicitly stated.
• Design test plans, scenarios, and checklists for AI-powered features where expected results are probabilistic.
• Perform manual functional, regression, and exploratory testing across web and mobile.
• Test AI outputs for hallucinations, incomplete retrieval, confidently wrong answers, and failure to apply business rules.
• Inspect API requests and responses via DevTools or Postman to verify what data the system actually used — not just what it showed.
• Document and report bugs with enough context that developers can reproduce and diagnose them.
• Collaborate closely with developers, product managers, and AI engineers.
• Present findings clearly to both technical and non-technical stakeholders.

Benefits

• Annual paid vacation: 20 days-off per year during the first 3 years, further increasing to 25 days in later years.
• Paid sick leave, 10 national holidays, and 2 company days-off.
• Well-being budget.
• Health Insurance allowance.
• Maternity/paternity leave.
• Accounting assistance.
• Reimbursement of expenses for professional development courses/certifications (up to 100% in agreement with the Manager).
• Hardware upon business needs.
• Strong positive engineering culture, a tightly-knit team of professionals with a good sense of humor.
