About Maino.ai

Maino.ai is an AI-driven technology company focused on building innovative and scalable solutions that simplify and enhance business operations. We are a fast-growing team passionate about creating impactful products, moving quickly, and solving real-world problems through technology and creativity. At Maino.ai, we value ownership, collaboration, and continuous learning. We offer a dynamic environment where individuals are encouraged to take initiative, contribute ideas, and grow alongside the company.

We process large volumes of analytics data where accuracy is critical — even a small bug in a filter or aggregation can mislead customers. We are looking for a QA Engineer who approaches quality as a system of contracts to validate, challenge, and break.

What you'll do

• Own and drive the quality bar across backend services, data pipelines, and reporting systems
• Design and execute comprehensive test plans covering edge cases, boundary conditions, and integration failures
• Build and maintain automated regression suites (API and end-to-end) integrated with CI pipelines
• Validate backend outputs against source-of-truth data using SQL
• Identify, reproduce, and document production issues with clear severity and impact
• Test asynchronous systems (queues, scheduled jobs, integrations) for race conditions and consistency issues
• Define release-gating criteria — what blocks vs. what can ship with known issues
• Contribute to QA processes including test data strategy, bug triage, and post-mortems

Must-Have Skills

• 3+ years of QA experience with strong expertise in API testing (Postman/Newman, REST Assured, or pytest + requests)
• Solid SQL skills — joins, aggregations (GROUP BY, HAVING), and subqueries
• Strong analytical mindset — ability to think through edge cases (nulls, empty values, incorrect types, etc.)
• Experience with multi-tenant systems and data isolation testing
• Hands-on experience in test automation (pytest, Jest, Cypress, or Playwright)
• Familiarity with CI/CD tools (Jenkins, GitHub Actions, or similar)
• Experience testing asynchronous workflows and integrations
• Excellent written communication skills for clear and actionable bug reports

Good to Have

• Experience with performance/load testing tools (k6, JMeter, Locust)
• Understanding of cloud environments (AWS or similar), caching, and observability tools
• Exposure to analytics-heavy or time-series data systems
• Experience creating long-lasting test documentation

Nice to Have

• Basic scripting knowledge in Python or Node.js
• Familiarity with relational and time-series databases
• Experience mentoring junior QA engineers or leading bug-bash sessions

Who You Are Not

• A manual-only tester without automation or scripting experience
• A UI-only automation specialist with limited backend understanding
• Someone who treats QA as a checklist instead of an engineering function

Interview Process

• Recruiter screening
• Technical evaluation (API + SQL)
• Practical exercise (take-home or live pairing)
• Systems & integration discussion
• Final round (culture & collaboration)

We aim to keep the process meaningful and efficient, with decisions shared within one week of the final round.

What you'll get

• A strong voice in engineering decisions — QA directly influences release quality
• Opportunity to work on systems where your work has real business impact
• Mentorship from experienced engineers who value quality as a core function
• Competitive salary, equity, health insurance
• A flat, fast-moving, and low-process work culture
