Lead Software Engineer in Test

About The Position

CD Baby is seeking a Lead Software Engineer in Test to be the senior-most quality voice on CD Baby’s flagship customer-facing software: the members application our artists use to distribute their music, get paid, and understand their audiences, and the .com marketing site that brings new artists into the platform. This is a hands-on, individual-contributor role with broad technical authority over how we test — the engineer who treats quality as a software engineering discipline and builds the practice to prove it. In the near term, you will help carry our customer-facing platform across the finish line for a brand relaunch worthy of CD Baby — standing up the automated coverage, the test data, and the CI/CD gates that let us ship with confidence. Beyond launch, your defining mandate is to architect our testing practice from the ground up: choose the frameworks, build the suites, integrate them into our delivery pipeline, and make automated, AI-augmented testing a first-class capability of the team as our customer-facing stack evolves from a .NET monolith into a modular, API-driven, service-based architecture. This is a role for an engineer who is energized by both the discipline of writing the code that proves our software works every day, and the craft of designing a testing program that scales with the platform underneath it.

Requirements

10+ years of software engineering experience with a deep specialization in test automation, or equivalent experience as a Senior/Staff/Lead SDET, SET, or Quality Engineer at companies that treat testing as an engineering discipline.
Demonstrated track record of architecting a testing practice from early stage to mature — selecting frameworks, building suites, integrating them into CI/CD, and earning the trust of the engineering organization over time.
Phenomenal hands-on coding ability. You write production-quality code, and your tests look like production code: well-factored, well-named, easy to maintain, and built to last.
Strong experience with Playwright (or comparable modern end-to-end frameworks such as Cypress or Selenium) and a clear point of view on when and how to use them.
Deep experience with API testing and contract testing, including testing the seams between your application and critical third-party APIs.
Experience designing and running performance and load testing programs, with the judgment to choose the right tooling for the workload (k6, JMeter, Gatling, Locust, etc.).
Hands-on experience applying AI to testing workflows — AI-assisted test authoring, suite generation, self-healing tests, AI-driven coverage analysis, or comparable approaches.
Strong experience integrating automated tests into CI/CD pipelines.
Working knowledge of the .NET and Next.js ecosystems sufficient to read and reason about the code you are testing.
A clear point of view on accessibility (WCAG) and usability testing, and the experience to back it up.
Excellent communication. You can explain a coverage gap, a flaky test, or a release risk to engineers, product partners, and executives with equal precision.

Nice To Haves

Familiarity with ArgoCD, Kubernetes, and containerized test environments is a plus; the ability to learn our specific stack quickly is required.

Responsibilities

Define and drive the multi-year evolution of CD Baby’s automated testing practice — from a nascent Playwright-based program today to a comprehensive, AI-augmented testing capability that scales as our architecture moves from monolith to services.
Choose the right tools for each layer of the test pyramid: UI/end-to-end (currently Playwright), API and contract testing, integration testing across our third-party API seams (FUGA, Zendesk, Trolley, and others integral to our operations), and performance and load testing.
Design and own the CI/CD test integration. Define how tests gate every release, what runs where, how fast feedback loops are kept fast, and how the suite earns trust over time.
Establish test data strategy, environment management, and the engineering patterns that keep tests reliable as the surface area grows.
Own the test suite for the entire flagship application. Write the code — the tests, the fixtures, the helpers, the harnesses — that proves the member application and the .com marketing site work as our customers expect, release after release.
Cover the .NET monolith we operate today, the Next.js front end, and the new services as they emerge.
Build coverage that travels with the architecture rather than fighting it.
Treat usability and stability as first-class quality concerns alongside functional correctness.
Use AI aggressively as a force multiplier. Drive AI-assisted test authoring, suite generation, and maintenance so that one senior engineer can credibly cover the full surface area of a complex product.
Embed on a cross-functional Platform team alongside front end engineers, back end engineers, a data engineer, a designer, and a product manager.
Participate in agile ceremonies as the customer and quality voice in the room.
Bring a QA lens to story refinement: what could break, what the edge cases are, what “done” really means.
Implement the automated tests that ship with each story.
Mentor by example: through the quality of your tests, the clarity of your reviews, and your willingness to sit shoulder-to-shoulder with another engineer when something is hard.
