Guard the quality of a system that ships several times a week: grow the automated test suites, turn real bugs into tests and check the interface in real browsers.
Benefits
- Social, health and unemployment insurance as required by Vietnamese labour law
- Paid annual leave and public holidays under the Labour Code
- A clear labour contract; salary negotiated on ability and stated in your offer letter
- Work on a stack that runs in production: TypeScript, React, Cloudflare Workers, D1, R2, Queues, Durable Objects
- Use AI every day — Claude, Gemini, Workers AI — in the product and in how we work
- Code ships with automated tests and is reviewed before it reaches production
- Equipment, remote work and bonuses: discussed in detail at interview
What you will do
- Write automated tests with node --test for Workers, business logic, permissions and money flows.
- Turn every bug reported by a real user into a failing test before it is fixed.
- Build headless Chrome checks: horizontal overflow on phones, tap targets that are too small, Vietnamese text leaking into the English pages.
- Test critical flows end to end: demo sign-up, payment, auto-publishing and client approvals.
- Track flaky tests and remove the root cause instead of re-running until green.
- Design test scenarios with engineers as early as the spec stage.
What we are looking for
- 2+ years in software testing, including automated testing in code.
- Able to program in JavaScript/TypeScript.
- Enough understanding of HTTP, browsers and databases to build your own test data.
- Meticulous and curious about how things break; you write bug reports others can reproduce.
Nice to have
- Experience with the Chrome DevTools Protocol, Puppeteer or Playwright.
- Experience testing payment or multilingual applications.
Hours & location
- Working hours: Office hours; your exact schedule is agreed at interview.
- Location: Ho Chi Minh City, Vietnam — the exact office address is sent with your interview invitation.
- Reports to: Engineering Team Lead.
Your application
- Your contact details and a few lines about yourself (required). A CV is optional — if you have one, attach a PDF, DOC, DOCX, JPG or PNG up to 10 MB.
- A link to your GitHub, portfolio or something you have built — one real project says more than a page of CV.
- If you can: measurable results from your work (revenue, customers looked after, campaigns, articles) — add them to your introduction.
- Degrees and certificates (if any) — only needed when you join, no need to send them in advance.
- SOZO never charges candidates any fee and never asks for photos of your ID over social media.
