Senior Quality Assurance Engineer

This is a remote position.

About Us:

Berkeley Payments is a leading payment technology provider specializing in innovative solutions for businesses to manage and process payments seamlessly. We pride ourselves on offering cutting-edge financial technology to our clients, empowering businesses to streamline operations and improve their payment processes.

Role Overview:

We are looking for a Senior Quality Assurance Engineer to be the senior quality voice on our technology team, sitting at the seam between product and engineering. This is a hands-on role that is roughly 60% test automation engineering, 30% release and risk strategy, and 10% exploratory and integration testing. The automation work splits across two surfaces: API and integration testing on the engineering side, and end-to-end Playwright testing on the product side, where you will partner directly with product managers to translate user flows and acceptance criteria into automated coverage.

You will be the senior QA presence in a team that today relies on developer-led testing, which means you will define how quality is engineered at Berkeley, not inherit a playbook. You will own the test automation framework, attend product reviews as the quality partner, partner with software engineering and DevOps to embed quality into CI/CD, and bring a risk-based lens to release decisions. We are looking for engineers who think like product owners about quality: where are the failure modes, what is the blast radius, and what is the cheapest test that catches the most expensive bug?

We are looking for someone who thrives in a fast-paced environment with evolving requirements. As a growing company with a startup mentality, you should be comfortable owning ambiguity, building from first principles, and shipping pragmatic solutions when textbook answers don't fit.

Key Responsibilities:

• Design, build, and maintain the automated test framework covering API, integration, and end-to-end flows for our payment platform.

• Build and own the Playwright-based end-to-end test suite for product-facing flows, partnering with product managers from spec through release.

• Attend product reviews and design discussions as the quality partner, surfacing edge cases, failure modes, and testability concerns before features are built.

• Use AI-assisted tooling (Playwright codegen, LLM-based test authoring, AI pair-programming tools) to accelerate test creation and maintenance, and bring a clear point of view on where AI tooling helps and where it doesn't.

• Own release quality strategy, including regression scope, risk-based test prioritisation, and go/no-go criteria for production deployments.

• Build and maintain integration test coverage against partner sandboxes, including card processor and banking rails, and detect contract drift before it reaches production.

• Partner with software engineering to shift quality left, including reviewing test coverage in pull requests, defining unit and integration test standards, and mentoring engineers on testable design.

• Work with DevOps to integrate automated testing into CI/CD pipelines, including parallelization, flake reduction, and environment management.

• Lead post-incident quality reviews: identify what testing would have caught a given defect, and close the gap with concrete coverage.

• Design and execute exploratory and chaos testing for high-risk flows such as authorization, settlement, dispute, and reconciliation.

• Define and track meaningful quality metrics: escape rate, mean time to detect, regression coverage on critical paths. Reject vanity metrics.

• Collaborate with product and engineering on test data strategy, including how we generate, mask, and refresh data for non-production environments.

• Investigate production defects alongside engineering, drive root cause analysis, and translate findings into permanent test coverage.

• Stay current on testing practices in payments, regulated fintech, and AI-assisted QA, and bring relevant approaches into the team.

• Identify and escalate risks related to release readiness, third-party integration changes, and data integrity in financial flows.

• Be comfortable withchanging requirementsand able to adapt quickly to new challenges and priorities as they arise in astartup environment.

Tech Stack:

• Backend: Elixir, Golang

• Frontend: React, Javascript

• Databases: MySQL, PostgreSQL

• APIs: RESTful services

• DevOps: AWS, Docker, Kubernetes, Spinnaker, Jenkins

• Version Control: Git, GitHub

• Infrastructure as Code (IaC): Terraform

• Test tooling:Playwright for end-to-end, with API and integration framework choice open. We expect you to bring a point of view and use AI-assisted authoring tools (Playwright codegen, LLM pair-programming) as part of your normal workflow.

Qualifications:

• Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent work experience.

• 5+ years of QA engineering experience, with at least 2 years building or substantially extending a test automation framework from the ground up.

• Hands-on experience with Playwright (or equivalent modern E2E framework such as Cypress) for end-to-end testing of web applications.

• Strong programming skills in at least one of TypeScript/JavaScript, Go, or Python. You write production-grade test code, not scripts.

• Demonstrated use of AI-assisted tooling in your QA workflow (Playwright codegen, Claude, Cursor, Copilot, or similar) and a thoughtful view on where it adds value and where it introduces risk.

• Deep experience testing REST APIs and microservices, including contract testing, integration testing against third-party sandboxes, and handling asynchronous flows.

• Proven track record owning release quality decisions, not just executing test plans handed to you.

• Experience working directly with product managers and designers, attending product reviews, and translating product specs into automated test coverage.

• Strong SQL skills and comfort validating data integrity directly against databases.

• Experience embedding automated testing into CI/CD pipelines.

• Ability to reason about risk in financial or other high-consequence systems and prioritise accordingly.

• Excellent written communication. You will write RCAs, test strategy docs, and risk assessments that go to engineering leadership.

Preferred Skills:

• Experience in payments, banking, or another regulated domain where defects have financial or regulatory consequences.

• Familiarity with card processing concepts: authorization, clearing, settlement.

• Experience with visual regression testing, accessibility testing, or other product-quality dimensions beyond functional correctness.

• Experience with performance and load testing tools (k6, JMeter, Gatling, or similar).

• Experience with security-adjacent testing such as authentication and authorization edge cases, input validation, and rate limiting.

• Familiarity with AWS services and Kubernetes-based environments.

• Exposure to agentic or self-healing test approaches and an informed view on their current maturity.

• Prior experience as the first or founding QA hire on a team.

• Agile development experience and comfort with Jira and Confluence.
