QA Engineer Full-Stack AI Engineering (HCMC)

Trusting Social is an AI Fintech pioneer thats revolutionizing credit access in emerging markets. Our mission is Advancing AI to Meet the Financial Needs of Everyday Consumers with Empathy. Weve assessed over 1 billion consumers across four countries and were on a mission to provide 100 million credit lines using the power of AI and Big Data.

At Trusting Social quality is engineered not inspected in. Our QA engineers are full-stack AI-native engineers who own an entire product or partner-integration track from test design and automation through defect root-cause release verification and go/no-go decisions. You will work closely with backend frontend mobile and data engineers to build deterministic test infrastructure gate releases on real evidence and push quality left before a single line of production code ships. You are not a gatekeeper at the end of a pipeline; you are an architect of quality from day one.

The person who thrives here is obsessed with correctness and uncomfortable with it probably works. You act on early signals without waiting to be directed experiment quickly and raise the bar by instinct not by mandate. You listen carefully before escalating synthesize signals from logs and data before filing a bug and hold yourself accountable for the downstream impact of every release decision you make.

Quality Ownership End-to-End

• Own quality for a product or partner-integration track from test design and automation through defect investigation verification and release sign-off the call is yours and you make it without waiting for central approval.
• Set and hold the quality bar: executable specs failing-test-first discipline and the judgment to distinguish real-green from false-green.
• Model release and migration risk before go/no-go gate the release on evidence and ship tooling that removes QA as a bottleneck for the team.

Test Infrastructure as First-Class Software

• Build and maintain automated test suites data-driven API E2E mobile and visual/responsive coverage committed to shared repos with reusable helpers the whole team runs on.
• Design deterministic test infrastructure: service mocks real-to-mock mode switches CI gates and test-data tooling that keep tests fast reliable and trustworthy.
• Instrument tests and CI pipelines to surface coverage gaps and quality drift before they reach production.

AI-Native Quality Engineering

• Drive Claude Code and equivalent agents through a disciplined loop brainstorm plan test-first verify in isolated worktrees and own the machine-readable domain docs your teammates and agents depend on.
• Act as an AI Operator for quality workflows: keep agent-driven testing above quality threshold at target cost catch drift early and verify AI output with the same rigor you apply to production code.
• Curate and evolve the skills and context that make AI agents more effective in your domain you build AI-augmented quality systems not just use them.

Exploratory and Risk-Based Testing

• Design and execute exploratory testing where automation is blind: new surfaces migration edge cases and the scenarios only a quality-obsessed human thinks to try.
• Investigate defects through production tooling Datadog Temporal Kafka SQL and file findings with reproducible steps real impact and a clear root-cause diagnosis engineers can act on immediately.
• Review specs and designs upstream to identify risk early before automation is even written.

Experience & Background

• 3 years in QA engineering with hands-on test automation across APIs Web UI and Mobile.
• Proficiency in TypeScript/JavaScript (Node) you write code that is readable tested and reviewable.
• Solid SQL and relational database skills for data validation and root-cause investigation.
• Startup or fast-growth tech background is a strong plus; fintech lending payments or eKYC domain experience is a bonus.
• Bachelors in Computer Science/Engineering or equivalent practical experience.
• Mobile automation visual-regression or performance testing is a strong plus; so is hands-on experience with CI/CD contract/mock testing or observability tooling (Datadog Temporal Kafka).
• A track record of mentoring peers or shipping test frameworks that others adopt is an advantage.

How You Work

• You apply AI actively and critically: you craft clear prompts evaluate agent output with a testers eye and use AI to expand your testing scope and depth not to shortcut quality judgment.
• You have a bias for action: you dont wait for a perfect test plan before running the first test; you iterate on real evidence ship better coverage each cycle and drive results without being directed.
• You connect across domains: you coordinate naturally across backend frontend mobile and external partners bringing a whole-system perspective that single-track engineers miss.
• You invest in your own growth: you self-direct your learning keep pace with tooling evolution and raise your own bar continuously without being asked.
• You consider before escalating: you listen to signals from across the system synthesize evidence before raising an issue and communicate findings with the clarity and precision that earns cross-functional trust.
• A sharp eye for both functional and visual detail: you notice when something is out of place and you name it.
• You dig into the system: you follow logs data and API calls to understand why something fails not just that it fails.
  

Skills & Competencies

• Domain Expert You can teach QA process and automation craft to others; your test strategies cover edge cases and your frameworks are documented well enough that teammates adopt them without hand-holding.
• AI Operator You keep agent-driven and AI-assisted quality workflows above quality threshold at target cost; you catch model drift early and know when to trust AI output and when to override it.
• Platform Guardian You design CI gates and quality guardrails before features ship not after; audit-readiness and test coverage transparency are defaults not afterthoughts.
• Strong English communication skills (spoken and written professional fluency required).
• High adaptability and comfort operating in fast-paced ambiguous environments.
