Job description

Senior QA Engineer (Manual + Automation)

Location: Bali (relocation sponsored)
Team: Application Engineering

Why GigRadar?We’re the bootstrapped, scrappy crew behindGigRadar.io
the AI-powered growth engine for 800+ Upwork-first agencies. Shipping fast is our default, and quality is non-negotiable. Your mission: break our productbeforeour users do, then help us bullet-proof it.

What you’ll own

• Test strategy & execution– author, maintain, and continuously improve test plans, cases, scenarios, and checklists across web (React/TypeScript) and service layers (REST, GraphQL).
• Automation at scale– build and extend reliable Playwright / Puppeteer suites for regression, smoke, and performance. CI is GitHub Actions; flaky tests get no mercy.
• LLM safety testing– design adversarial prompt-injection and jailbreak scenarios for our Langfuse/OpenAI pipelines; validate guardrails, rate limits, and red-team exploits.
• API diligence– craft Postman / code-level tests that hammer our endpoints, validate schema changes, and surface latent edge-cases.
• Quality culture– pair with devs on PRs, champion shift-left testing, and turn bug reports into repeatable test artifacts.

Must-haves

• 5+ yrs hands-on QA (mix of manual + automation) in modern SaaS.
• Pro in JavaScript/TypeScript test automation (Playwright or Puppeteer).
• Deep knowledge of REST & GraphQL testing (Supertest, pact, or similar).
• Battle scars from red-teaming LLM apps: prompt injection, jailbreaks, safety evals.
• Solid fundamentals: test design techniques, risk-based testing, defect lifecycle, traceability.
• Able to work async, write crisp docs, and give ruthless feedback.

Nice-to-haves

• Experience with Langfuse, LangChain, or other LLM observability tools.
• Exposure to CI/CD on GitHub Actions and Vercel.
• Basic performance / load testing chops (k6, Artillery, etc.).

What’s in it for you

• Autonomy, not bureaucracy– ship improvements end-to-end.
• Direct impact– your work touches thousands of proposals a day.
• Fair comp + meaningful equity– we’re scaling, you’ll ride the upside.
• Annual off-site in Bali (surf’s up).
