How QA Mentorship Drives Software Quality

QA team and mentorship

Stefan Antov, QA Automation Team Lead at TINQIN, believes the answer lies in something more profound than tooling or test coverage: mentorship. With over 15 years in software quality engineering, Stefan leads a growing QA organization focused on validation and teaching others how to think like quality owners.

Product quality isn’t negotiable in high-stakes industries like insurance and health tech—it’s a business differentiator. But how do you ensure quality at scale, especially while growing teams, onboarding new engineers, and evolving product complexity? We sat with him to explore how mentorship, structure, and strategic QA enable TINQIN to scale software delivery without sacrificing quality.


Why Mentorship Is a Delivery Strategy

“Mentorship isn’t just knowledge transfer. It’s cultural alignment and risk mitigation,” says Stefan.

TINQIN’s QA team includes over 35 manual and automation engineers. As the company rapidly expands its delivery footprint, onboarding and mentorship have become embedded components of product readiness. New QA engineers don’t just join projects—they’re guided through:

  • The rationale behind the test strategy, not just the execution
  • Tooling decisions and architectural context
  • Practices for working in cross-functional, regulated environments

“In a sector like insurance, miscommunication between dev and QA doesn’t lead to bugs—it leads to breaches of trust. That’s why mentorship matters.”


Scaling Smart, Not Fast

TINQIN’s hiring philosophy centers on long-term potential, not just technical fluency.

“We look for mindset first,” Stefan explains. “Frameworks change. But people who are proactive, pragmatic, and communicative—those who grow into our ecosystem.”

Mentorship is also used as a buffer during scale-up. As new engineers join, experienced team leads support them through structured onboarding, code and test reviews, and sprint-level retrospectives—avoiding the costly dip in quality that often accompanies rapid growth.


Creating QA Owners, Not Just Test Executors

Stefan believes that the best QA engineers don’t just execute test cases—they shape product development through early feedback, architecture awareness, and system intuition.

“The goal is to cultivate ownership—people who ask why, not just how.”

Mentorship at TINQIN focuses on:

  • Understanding the product’s business logic, not just technical paths
  • Developing judgment around what to test and when
  • Teaching engineers how to anticipate failure before it’s visible

Tooling Is Only Half the Picture

TINQIN’s QA automation stack includes:

  • Selenium WebDriver, REST Assured, and TestNG
  • Custom internal frameworks for test management, environment setup, and validation
  • Direct integration with CI/CD pipelines for visibility and traceability

But Stefan quickly points out that tools serve strategy, not vice versa.

“We build frameworks that are maintainable by the team, align with our dev stack, and can be taught easily to new hires. Simplicity scales better than cleverness.”


QA Is a Product Capability, Not a Gatekeeper

For CTOs evaluating engineering partners, QA maturity can be a revealing differentiator. At TINQIN, QA is a collaborative force embedded across delivery squads.

  • Integration and end-to-end testing validate early and often
  • Teams share test visibility across engineering and product
  • QA mentors help software engineers anticipate issues, not just respond to bugs

“The best QA strategy is one that the entire team understands and supports. That’s how you embed quality into delivery—not after it.”

Final Word: Mentorship as Infrastructure

TINQIN’s QA mentorship program is a core mechanism for delivering stability, team growth, and cultural continuity.

For CTOs, this means:

  • Faster time-to-productivity for new engineers
  • Lower delivery risk during scale-ups
  • Stronger alignment across QA, development, and business goals
