JOB OVERVIEW

We're looking for a skilled full stack QA engineer to help us maintain and improve our startup's core platform. This role is heavily focused on detecting bugs and system issues, managing a support engineer, as well as larger ongoing feature development.

Must haves:
- Great communication skills to describe bugs or new features and how to work on larger projects
- Excellent experience with Typescript, Next.js, React.js, and PostgreSQL
- Experience using AI coding tools (like Cursor, ChatGPT, Claude Code, Copilot, etc.) to speed up debugging and development workflows
- Excellent debugging skills and the ability to quickly understand and navigate large codebases
- Confident building, testing, and deploying software locally
- Comfortable creating and iterating on pull requests on GitHub

Nice to haves:
- Good eye for design and good UI/UX design for businesses
- Habit of writing tests for your fixes and changes
- Previous startup experience

To apply:
- Message me on WhatsApp at +1 (908) ---------- with your resume, GitHub, and any relevant projects or websites.
- In order to get selected, you MUST write "Social media agency" in your message along with the process below:

The process:

Step 1 — Async QA & Bug Review:
We want to see how you identify issues in real code. Please complete the following:
1. Review the git diff for a recent onboarding branch:
----------
2. Test the live onboarding flow here:
----------

Send us a write-up that includes:
- Any code-level issues you find in the diff (bugs, logic errors, missing edge cases, etc.)
- Any UX issues you find while testing the onboarding flow (broken interactions, confusing copy, layout problems, accessibility concerns, etc.)
Please send this along with your resume. If you do not send this, your application will NOT be considered.

Step 2 — Live Coding:
- A quick 30 min live coding test with me — a simple JavaScript question where you'll walk me through your approach.

Step 3 — Final Round:
- Async code review plus a short call with my colleague, where we'll discuss your experience and show you some sample code from our codebase.

If accepted, there is a paid trial where you work on features immediately.
