Job Details

Have 3 to 5 years of experience in QA engineering, SDET, or test automation.
Demonstrate a shift from manual execution toward automated test coverage.
Have strong programming ability in at least one of TypeScript, JavaScript, or Python.
Have hands-on experience with Playwright, Cypress, Selenium, pytest, or an equivalent automation framework.
Have practical API testing experience, including contract, integration, and negative-path testing against REST or GraphQL services.
Have working knowledge of CI/CD systems such as GitHub Actions, GitLab CI, or Jenkins, and be comfortable owning pipeline configuration.
Use AI coding assistants and LLM tooling daily, and understand where their output requires verification.
Be comfortable with Git, containerized local environments, and reading application code.
Provide clear written communication, including bug reports and test plans.
Show autonomy and self-direction in a fast-moving environment.
Be willing to learn the technical aspects of blockchain, smart contracts, and cybersecurity.
Bonus: Experience testing Web3 applications, wallet flows, testnets, RPC interactions, or Foundry or Hardhat.
Bonus: Experience with LLM feature evaluation harnesses, security testing or OWASP, performance and load testing, observability, or testing and developer-tooling contributions.

Own test strategy for internal engineering platforms and client-facing products, covering unit, integration, end-to-end, and regression testing.
Design, build, and maintain fast, deterministic automated UI, API, and data-layer test suites.
Use LLM-assisted tooling to author tests, generate edge cases, triage failures, and summarize regressions.
Build and tune CI/CD quality gates to prevent broken builds from reaching client environments.
Automate manual QA processes, including release checklists, environment setup, test data generation, smoke verification, and reporting.
Reproduce, isolate, and document defects with clear reproduction steps and expected versus actual behavior.
Partner with security engineers to integrate security regression checks into the standard pipeline.
Run performance, load, and reliability tests against services handling sensitive audit and engagement data.
Define and report quality metrics, contribute to release readiness decisions, and advise whether releases are ready to ship.
