3 to 5 years in QA engineering, SDET, or test automation with a focus on automation.
Strong programming skills in TypeScript, JavaScript, or Python, producing maintainable test code.
Experience with automation frameworks like Playwright, Cypress, Selenium, or pytest.
Proficient in API testing across REST or GraphQL, including contract and integration testing.
Familiarity with CI/CD tools such as GitHub Actions, GitLab CI, or Jenkins.
Experience using AI tooling for coding assistance and test authoring.
Comfortable with Git and containerized environments.
Responsibilities
Own the test strategy for both internal and client-facing products, covering all types of testing.
Design, build, and maintain automated test suites across UI, API, and data layers.
Utilize LLM-assisted tools to create test cases and summarize regression results.
Implement quality gates in CI/CD to ensure only stable builds are deployed.
Automate manual QA processes like release checklists and environment setup.
Document and report defects clearly for swift resolution by engineers.
Coordinate with security engineers to incorporate security checks into testing pipelines.
Benefits
Opportunity to work with cutting-edge technology in blockchain and cybersecurity.
High degree of autonomy in a dynamic work environment.
Collaborative and distributed team culture focusing on clear communication.
Potential for growth and learning in advanced technology areas.
Full Job Description
Responsibilities
Own the 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.
Qualifications
3 to 5 years in QA engineering, SDET, or test automation, with a demonstrated shift from manual execution toward automated coverage.
Strong programming ability in at least one of TypeScript, JavaScript, or Python - you write test code that other engineers are willing to read and maintain.
Hands-on experience with modern automation frameworks such as Playwright, Cypress, Selenium, pytest, or equivalent.
Practical API testing experience, including contract, integration, and negative-path testing against REST or GraphQL services.
Working knowledge of CI/CD systems (GitHub Actions, GitLab CI, Jenkins, or similar) and comfort owning pipeline configuration yourself.
Daily, deliberate use of AI coding assistants and LLM tooling in your own workflow, with a clear point of view on where they help and where they must be verified.
Comfort with Git, containerized local environments, and reading application code to understand what you are testing rather than testing blind.
Excellent written communication - in a distributed, asynchronous team, a well-written bug report or test plan is the deliverable.
High autonomy and strong self-direction in a fast-moving environment where priorities shift.
Willingness to learn the technical aspects of blockchain, smart contracts, and cybersecurity.
Bonus Points
Experience testing Web3 applications - wallet flows, testnets, RPC interactions, or smart contract tooling such as Foundry or Hardhat.
Experience building evaluation harnesses for LLM-powered features, including regression testing of non-deterministic output.
Background in security testing, OWASP methodology, or hands-on time with tools like Burp Suite.
Performance and load testing with k6, Locust, JMeter, or similar.
Experience with observability tooling and using production telemetry to find gaps in test coverage.
Open source contributions to testing frameworks or developer tooling.
Knowledgeable of the latest trends in Blockchain and DeFi.
