Company Overview

Our client is a fast-growing Web3 fintech startup headquartered in Vancouver, Canada, building the world’s first self-custody stablecoin neobank. Backed by top-tier investors including YZi Labs, DraperDragon, Amber Group, and KuCoin Ventures with over US.6M raised, the company provides stablecoin-powered invoicing, payroll management, social commerce checkout, and cross-border settlement solutions for small and medium-sized businesses globally.

The founding team consists of veterans from Binance, OKX, Kraken, Block (Square), Capital One, TikTok, and Amazon. Using account abstraction and AI-powered financial copilots, the platform makes blockchain technology invisible to end users — enabling seamless stablecoin adoption at scale.

Key Responsibilities

1. Own end-to-end testing of web applications and APIs, including functional, integration, regression, and E2E testing to ensure system quality and stability.

2. Design, develop, and maintain comprehensive test cases to continuously improve test coverage.

3. Lead or contribute to building automated testing frameworks (API automation, E2E automation).

4. Write test scripts and develop testing utilities using Python to improve efficiency and scalability.

5. Perform API testing (REST / GraphQL) and validate business logic and data integrity.

6. Manage and track defects; collaborate with developers to reproduce and resolve issues.

7. Set up and maintain test environments; integrate automated tests into CI/CD pipelines.

8. Collaborate closely with product and engineering teams; participate in requirement reviews and identify quality risks early.

9. Analyze production issues and logs to continuously optimize testing strategies and the overall quality system.

Requirements

Must-Have

1. Bachelor’s degree or above (CS or related fields preferred but not required).

2. 3+ years of software testing experience, preferably in web or internet application environments.

3. Strong understanding of software testing methodologies (functional, regression, integration testing, etc.).

4. Proficiency in Python with the ability to write test scripts and automation tools.

5. Hands-on experience with automation frameworks such as pytest, Cypress, or Playwright.

6. Familiarity with API testing tools (Postman, httpx) and testing methodologies.

7. Experience with defect tracking and collaboration tools (Jira, Notion, Trello).

8. Strong analytical and problem-solving skills; detail-oriented and responsible.

9. Proficiency in Mandarin Chinese (spoken and written) — the engineering team primarily communicates in Mandarin.

Nice-to-Have

• Front-end or back-end development experience; ability to read and debug code.

• Familiarity with CI/CD pipelines (Jenkins, GitHub Actions) and automated test integration.

• Performance/load testing experience (Locust, JMeter).

• Experience testing microservices or distributed systems.

• Familiarity with logging/monitoring tools (Grafana, Loki).

• Ability to independently design test strategies and drive quality improvements.

Compensation & Benefits

• Competitive base salary (range is open and flexible based on candidate caliber).

• Stock options / token allocation available.

• Partial compensation in stablecoins (USDT/USDC) can be arranged.

• Join a well-funded early-stage Web3 startup with significant growth trajectory.
