- Vessel identity and carrier vessel tracking features, including new layers and datasets added to the core map over the past several years;
- The Public/Private APIs — a major strategic expansion now providing external developers and researchers with programmatic access to datasets and services. API quality, reliability, and contract testing are a core responsibility of this role.
- Tools for users to upload, display, and analyze their own datasets alongside our datasets
Our Stack

- Selenium (legacy; knowledge helpful but not the focus)
- Jest and axios
- Modern JavaScript / TypeScript (ES6+)
- React (hooks) and Redux
- Mapping and dataviz: Deck.gl, D3, turf
- CSS3, CSS Modules
- Node.js (Nest and Koa), Go, Python, PostgreSQL, Clickhouse
- Google Cloud Platform (GCP)
- Docker
- CI/CD: Google Cloud Build
- Git and GitHub
- Postman
Principal Duties and Responsibilities
- Design, build, and maintain automated test suites for our front-end products and public API — this is the primary and non-negotiable function of this role:
- Lead end-to-end test automation using Playwright, covering functional, regression, cross-browser, and performance scenarios;
- Own API test automation: write and maintain contract tests, functional tests, and integration tests for GFW's public and internal APIs;
- Integrate automated test suites into CI/CD pipelines (Cloudbuild), ensuring tests run reliably on every relevant trigger;
- Design and document test cases for user stories; validate acceptance criteria with the product team before implementation begins;
- Define and maintain test suite organization — smoke, regression, and full suites — and determine which cases warrant automation vs. manual execution;
- Run and maintain regression suites when new features are released or underlying data versions change;
- Conduct periodic regression runs on production environments;
- Work closely with the product team during user story definition to ensure testability and clear acceptance criteria from the start; Creating a test plan for every release;
- Report bugs clearly in the issue tracking system and follow up until resolution working closedy with product to understand impact of the bug and define priority;
- Define, record, and report on QA metrics to assess coverage, test reliability, and areas of product risk;
- Advance overall QA strategy, tooling, and infrastructure over time.
Required Technical Skills
- Automation is the core of this role. Candidates who cannot demonstrate hands-on automation experience will not be considered.
- 5+ years of hands-on experience building and maintaining automated test suites for production web applications — please be prepared to discuss specific projects and outcomes;
- Proven, recent experience with Playwright for end-to-end browser automation (required);
- Solid experience with API test automation: writing contract tests, functional API tests, and integration tests;
- Experience working in Agile teams with sprint-based delivery;
- Experience with CI/CD integration of automated tests (GitHub Actions or equivalent);
- Experience with performance and cross-browser testing;
- Experience with test plan and test case development, including defining what to automate vs. test manually;
- Willing to comb through a complex network of interdependent tools, resources, user roles, and permissions;
- Detail-oriented, with a mindset geared toward finding edge cases and breaking things.
- Experience with Cypress in addition to Playwright;
- Experience testing non-traditional, data-heavy applications using maps, charts, heatmaps, or other data visualizations;
- Strong proficiency with Git and modern branching strategies;
- Familiarity with Docker and containerized test environments;
- Experience with cloud platforms, particularly Google Cloud Platform;
- Open-source collaboration experience.
- •Strong written and verbal communication in English — most day-to-day collaboration is async and written. Having also good verbal Spanish is a plus;
- Comfortable working remotely and independently in a small, fast-moving organization;
- Proactive and highly organized — owns tasks end-to-end without needing to be chased;
