QA Engineer — Blockchain Security & Test Automation

Halborn; Myrtle Point (OR); On-site; USD 90,000 - 140,000; Full time

Job summary

Halborn is seeking a QA engineer/SDET to own test strategy across internal platforms and client-facing products. You will design, implement, and maintain automated UI, API, and data-layer tests to keep releases fast and reliable.

Work with security engineers to integrate regression checks, leverage AI-assisted tooling, and drive CI/CD quality gates. Must read code, write clear bug reports, and continuously expand automated coverage in a distributed, blockchain-focused environment.

Qualifications

• 3 to 5 years in QA engineering, SDET, or test automation.
• Strong programming in TypeScript, JavaScript, or Python.
• Hands-on with modern automation frameworks such as Playwright, Cypress, Selenium, pytest, or equivalent.
• Practical API testing experience, including REST or GraphQL.
• Working knowledge of CI/CD systems and ownership of pipeline configuration.

Responsibilities

• Own test strategy for Halborn's internal engineering platforms and client-facing products, from unit and integration coverage through end-to-end and regression suites.
• Design, build and maintain automated test suites in code - UI, API, and data-layer - and keep them fast, deterministic, and trusted by the engineers who depend on them.
• Use LLM-assisted tooling to accelerate test authoring, generate edge cases from specs and diffs, triage failing runs, and summarize regressions for the team.
• Build and tune quality gates in CI/CD so that broken builds never reach a client environment, and so that the feedback loop stays measured in minutes.
• Identify manual QA processes and automate them out of existence - release checklists, environment setup, test data generation, smoke verification, reporting.
• Reproduce, isolate, and file defects with unambiguous repro steps, expected versus actual behavior, and enough context for an engineer to fix it without a follow-up conversation.
• Partner with security engineers to fold security regression checks - authentication, authorization, input handling, secrets exposure - into the standard pipeline.
• Run performance, load, and reliability testing against services handling sensitive audit and engagement data.
• Define and report the quality metrics that matter: escaped defect rate, flake rate, coverage of critical paths, and time to detection.
• Contribute to release readiness decisions and act as an informed voice on whether something ships.
