Paragon is building the infrastructure layer that powers integrations for modern SaaS companies. We help teams ship and operate integrations faster so product teams can focus on their core product instead of integration complexity. Our platform runs mission-critical integrations in production for fast-growing startups and large enterprises.
Paragon’s Workflow Engine gives customers a way to build, run, and manage complex workflows on top of their integrations. These workflows often involve triggers, branching logic, retries, asynchronous execution, third-party APIs, and failure handling across multiple systems.
Quality on this team is not just about checking UI flows. It means validating that workflows behave correctly end to end, including execution state, retry behavior, scheduling, error handling, and the product experience customers use to build and debug workflows.
We’re looking for a QA Automation Engineer who can raise the quality bar across this surface area through strong Playwright-based automation, backend and API validation, and a sharp eye for edge cases in complex systems.
Build and maintain automated test coverage for the Workflow Engine using Playwright
Validate critical product flows end to end, from workflow creation and configuration through execution and debugging
Test backend services, APIs, webhooks, and asynchronous workflow behavior in addition to UI flows
Design coverage for complex scenarios including retries, branching logic, partial failures, race conditions, scheduling, and long-running execution
Partner closely with engineers and product managers to improve testability, clarify acceptance criteria, and catch issues earlier in the development cycle
Improve the quality of our CI signal by reducing flakiness, increasing reliability, and making failures easier to debug
Build reusable fixtures, test data setup, helpers, and tooling that make automation easier to write and maintain
Investigate product issues and test failures deeply to identify root cause and prevent recurring regressions
Help define the quality strategy for one of the more complex parts of the Paragon platform
Strong hands-on experience with Playwright and end-to-end automation for complex product flows
Experience testing backend systems, APIs, and asynchronous or event-driven workflows
Strong debugging skills across browser tests, APIs, logs, and distributed system behavior
Ability to reason through stateful systems and edge cases like retries, timing issues, duplicate events, partial failures, and long-running jobs
Experience building and maintaining stable automation in CI/CD environments
Strong coding skills and comfort working in a modern engineering codebase
Ability to work closely with engineers and act as a quality owner, not just a test executor
Clear communication and sound product judgment around risk, coverage, and release quality
Experience with TypeScript
Experience testing workflow, orchestration, or automation products
Experience testing integrations, webhooks, and third-party APIs
Experience building reusable Playwright frameworks, fixtures, or internal testing tools
Experience with observability tools and production debugging
Experience with performance or reliability testing
The Workflow Engine is one of the more complex parts of our product. It sits at the intersection of product UX, backend systems, integrations, and asynchronous execution. Small issues can turn into confusing customer experiences or hard-to-debug failures.
This role is important because it helps us ship faster with more confidence. We want someone who can improve coverage on the paths that matter most, catch subtle regressions before they reach customers, and make quality a stronger part of how the team builds every day.
In the first few months, a strong hire will ramp up on the Workflow Engine architecture, understand the major failure modes, and start contributing meaningful automated coverage quickly. Over time, they will become a key quality owner for the team by improving end-to-end test coverage, increasing trust in CI, reducing flaky tests, and helping engineers ship changes to the Workflow Engine with confidence.
If you want, I can turn this into a tighter final version in your usual JD style, with the same tone and formatting as the SRE one.
