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 (and growing!) team members from 30+ countries around the world. We seek exceptional individuals around the world, set them up to do the best work of their lives, and in turn, create a meaningful impact in their own lives. We don't track hours, but we do manage for high expectations very closely. We collaborate across time zones, are highly async, and like to document a lot.

Twice a year, we bring the whole company together in beautiful places around the world for our company offsites. So far, we’ve hosted offsites in Turkey, Portugal, Mexico, Thailand, Colombia, Italy, Ireland, and more, with still more to come!

About the role

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.

What you'll be doing

Platform & Tooling

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, and observability hooks.
Handle AI & Innovation for Quality Engineering workflows.

Developer Experience

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).

Reliability & Quality 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).

Guardrails & Governance

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.

Paved Roads

Create “golden paths” for developers: out-of-the-box test setup, generated mocks & fixtures, recommended patterns and linting rules, fully managed test environments

What Success Looks Like

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.

What you'll need to be successful

Familiarity with Ruby (We use this in our backend systems)
Strong experience with Ruby to build or interact with backend services.
Experience building internal tooling, utilities, or engineering platforms.
Deep understanding of CI/CD (Buildkite, GitHub Actions, GitLab, CircleCI).
Knowledge of cloud environments (AWS, GCP, Azure) and containerisation (Docker, Kubernetes).
Strong understanding of architectural patterns.
Experience with quality telemetry, observability, or monitoring.
Experience with Performance, Load testing and tooling.

Quality Engineering Mindset

Shift-left and shift-right testing practices.
Testability-first thinking.
Ability to design high-leverage systems rather than isolated tests.
Understanding of resilience and reliability engineering principles.

Who You Are

You think like a platform builder, solving problems once so no one else has to.
You enjoy simplifying complex systems.
You care about engineering productivity and operational excellence.
You’re able to move between big-picture strategy and deep technical execution.
You’re collaborative, curious, and passionate about elevating quality across an organization.

Bonus Points

Experience with AI-assisted testing tools or test generation frameworks.
Knowledge of VCR/web mocking proxies, contract testing, and API schema validation.
Exposure to static analysis tools and code quality scanners.
Experience with platform engineering in any form (DevEx, SRE, Internal Platforms).
