Senior Quality Platform Engineer

Join to apply for the Senior Quality Platform Engineer role at Circle

Circle is building the world's leading all‑in‑one platform for online communities. We make it possible for creators, coaches, educators, and businesses to bring together their audience with engaging discussions, live streams, events, chat, courses, and payments— all in one place, all under their own brand.

We're proud to be a fully remote company of around 200 team members from 30+ countries. We seek exceptional individuals worldwide, set them up to do the best work of their lives, and in turn, create a meaningful impact. We don't track hours but manage high expectations closely, collaborate across time zones and asynchronously, and document extensively. Twice a year we bring the whole company together in beautiful places around the world for offsites in Turkey, Portugal, Mexico, Thailand, Colombia, Italy, Ireland and more.

We're moving beyond traditional testing. Quality at our organization is not a gate; it's a platform. As a Senior Quality Platform Engineer
, you will design, build, and maintain the internal tooling, automation, workflows, and quality infrastructure that empower teams to ship faster, safer, and with higher confidence.

This role sits at the intersection of software engineering, developer experience, and quality strategy. You won't just write tests—you'll build the systems that ensure quality is scalable, observable, measurable, and baked into every stage of development. If you're passionate about enabling teams, reducing friction, and approaching quality like a product, this role is for you.

• Develop and maintain the Quality Platform: frameworks, libraries, pipelines, and integrations that enable high‑quality delivery.
• Build reusable, language‑agnostic automation libraries and internal SDKs.
• Own CI/CD quality gates, test orchestration, and smart execution logic (e.g., test selection, caching, parallelisation).
• Implement and maintain recording/playback tools, contract testing, visual regression engines, and observability hooks.
• Handle AI & Innovation for Quality Engineering workflows.

• Improve feedback loops in local dev, PRs, staging, and production.
• Create self‑service tooling for engineers to generate tests, diagnose failures, and validate changes quickly.
• Embed quality signals into engineering workflows (e.g., risk scoring, flakiness insights, coverage intelligence).

• Build systems that convert quality noise into actionable insights.
• Own metrics dashboards: flakiness, failure cause classification, performance trends, release confidence.
• Partner with our Infrastructure team to implement resilience tests (chaos, reliability gates, SLIs/SLOs).

• Define and codify standards that scale across teams (naming conventions, folder structure, selector strategies, logging).
• Turn rules into automated guardrails rather than documentation.
• Work closely with our Infrastructure team to ensure safe automation practices, secrets handling, and permissions.

• Create “golden paths” for developers:
  • Out‑of‑the‑box test setup
  • Generated mocks & fixtures
  • Recommended patterns and linting rules
  • Fully managed test environments

• Developers spend more time building features and less time fighting tests.
• Release confidence increases while cycle time decreases.
• Flakiness is tracked, understood, and eliminated at its root.
• Teams can self‑serve 90% of testing and quality workflows.
• Quality signals become central to engineering decisions.
• The organization views Quality as a platform, not a department.

• Strong alignment with our values; find our values on our career page if you haven't read them yet.
• Proficiency in English (spoken, written, reading) at CEFR Level C2 / ILR Level 5.

• Strong experience in at least one modern testing framework (Playwright, Cypress, Jest, JUnit, etc.).
• Solid software engineering background (Type Script, JavaScript, Java, Python or similar).
• Familiarity with Ruby (used in our backend systems); strong experience building or interacting with backend services.
• Experien…
