FanDuel is hiring a Staff Software Engineer

FanDuel is hiring a Staff Software Engineer to own and evolve test automation for our Sportsbook Emerging Experiences—Social and Advanced Search—across iOS, Android, and Web. This is a hands-on technical leadership role focused on building reliable functional and performance automation that improves release confidence.

What You'll Do

• Design and implement end-to-end automation for core Social and Search journeys using Cypress (web) and Detox (iOS/Android), aligned to our Nx monorepo structure.
• Own and evolve the pillar’s automation foundations: test architecture, folder structure, screen-object patterns, shared utilities, and local-first run toolchains.
• Integrate automation into CI (Buildkite and/or GitHub Actions) with practices like affected execution, parallelization, and clear pass/fail reporting.
• Drive stability by tracking flakiness, improving test determinism, and shortening time-to-signal through better synchronization and failure triage.
• Establish a test data and environment strategy, using mocks/fixtures for acceptance and prod-like data for E2E, and implement contract tests (Pact or equivalent) where valuable.
• Build performance coverage for critical journeys (feed load, interactions, search latency) using Detox performance tooling and/or Flashlight + Maestro.
• Own load/performance testing for key end-to-end user journeys using Locust (Python) or equivalent, including realistic traffic modeling and assertions on p95/p99 latency.
• For Advanced Search (including LLM-powered experiences), define automated evaluation for schema checks, relevance regression, and safety checks.
• Partner with platform and observability teams to improve test visibility through dashboards and logging.
• Mentor and enable engineers and QA on automation authorship, local-first toolchains, and AI-assisted development workflows.

What We're Looking For

• 7+ years of experience in software test automation / quality engineering, including designing and maintaining automation frameworks at scale.
• Hands-on coding skills in TypeScript/JavaScript and/or Python.
• Strong end-to-end automation experience across web and mobile (Cypress and Detox preferred).
• Experience working in monorepos and CI/CD: Nx, Buildkite/GitHub Actions, and practices like affected runs and parallelization.
• Experience testing APIs and distributed systems, including test data setup and contract testing.
• Performance and reliability mindset: building performance baselines, running end-to-end load tests, interpreting p95/p99 latency, and reducing flaky tests.
• Staff-level leadership: proven ability to influence across teams, set standards, mentor others, and drive quality initiatives end-to-end.

Nice to Have

• Mobile performance tooling (Detox performance, Flashlight, Maestro) and/or web performance profiling (Lighthouse, tracing).
• Accessibility testing experience (axe, WCAG) and/or visual regression testing.
• Experience with observability and reporting (Grafana, ELK, Datadog) for test signal and CI analytics.
• Cloud and data tooling (AWS, Docker/Kubernetes) for test environments and data pipelines.
• Experience testing ML/LLM-powered search: evaluation datasets and regression across model/prompt changes.

Technical Stack

• Automation & Testing: Cypress, Detox, Locust, Pact, Flashlight, Maestro
• Languages: TypeScript, JavaScript, Python
• Infrastructure & CI/CD: Nx, Buildkite, GitHub Actions
• Cloud & Observability: AWS, Docker, Kubernetes, Grafana, ELK, Datadog

Team & Environment

You will partner closely with engineers, product, and QA to embed quality earlier in the development lifecycle.

Benefits & Compensation

• Compensation: $159k-$199k USD
• Health plans (some as low as $0 per paycheck) including programs for fertility and family planning, mental health support, and fitness benefits
• Generous paid time off (PTO & sick leave)
• Annual bonus and long-term incentive opportunities (based on performance)
• 401k with up to a 5% match
• Commuter benefits
• Pet insurance
