Staff Software Engineer

FanDuel • Atlanta, GA

About The Position

We’re looking for 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.
You’ll partner closely with engineers, product, and QA to embed quality earlier in the development lifecycle, build repeatable patterns in our Nx monorepo and CI, and raise the bar on what “release ready” means for user-critical journeys.
In addition to the specific responsibilities outlined above, employees may be required to perform other such duties as assigned by the Company. This ensures operational flexibility and allows the Company to meet evolving business needs.

Requirements

• 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; comfortable reading and contributing to production code.
• Strong end-to-end automation experience across web and mobile (Cypress and Detox preferred; Playwright, Appium, WebdriverIO, etc. are transferable).
• Experience working in monorepos and CI/CD: Nx (or similar), Buildkite/GitHub Actions, and practices like affected runs, parallelization, and fast feedback loops.
• Experience testing APIs and distributed systems: test data setup, SQL/NoSQL validation, and contract testing/mocking approaches where appropriate.
• Performance and reliability mindset: build performance baselines, run end-to-end load tests (Locust/k6/JMeter) that exercise BFF and downstream services, interpret p95/p99 latency and error rates, and reduce flaky tests through better design.
• Staff-level leadership: proven ability to influence across teams, set standards, mentor others, and drive quality initiatives end-to-end.

Nice To Haves

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

Responsibilities

• 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 so teams can add coverage quickly and consistently.
• Integrate automation into CI (Buildkite and/or GitHub Actions): affected execution, parallelization, clear pass/fail reporting, and quality gates that are actionable, while keeping suites easy to run locally for fast iteration.
• Drive stability: track flakiness, improve test determinism, and shorten time-to-signal through improved synchronization, test data control, and failure triage patterns.
• Establish a test data and environment strategy: mocks/fixtures for acceptance, prod-like data for E2E, and lightweight API/contract tests (Pact or equivalent) where they add value.
• Build performance coverage for critical journeys (feed load, interactions, search latency/rendering) using Detox performance tooling and/or Flashlight + Maestro; define baselines and regression thresholds.
• Own load/performance testing for key end-to-end user journeys (from BFF/edge APIs through platform and backend services) using Locust (Python) or equivalent, including realistic traffic modeling (ramp profiles, concurrency, think time), scenario design, assertions on p95/p99 latency, throughput, and error rates, and reporting.
• For Advanced Search (including LLM-powered experiences where applicable), define automated evaluation: schema/structure checks, relevance/quality regression vs baselines, and edge-case/safety checks.
• Partner with platform and observability teams to improve test visibility (dashboards, logging, artifacts) and ensure automation results are easy to interpret and act on.
• Mentor and enable: coach engineers and QA (including team members transitioning from manual to automated testing) on automation authorship, local-first toolchains, and AI-assisted development workflows (e.g., Cursor) so squads can confidently build and maintain test coverage.

Benefits

• We offer amazing benefits above and beyond the basics. We have an array of health plans to choose from (some as low as $0 per paycheck) that include programs for fertility and family planning, mental health support, and fitness benefits.
• We offer 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, and more - check out all our benefits here: FanDuel Total Rewards.
• Benefits differ across location, role, and level.
• medical, vision, and dental insurance; life insurance; disability insurance; a 401(k) matching program; among other employee benefits.
• This role may also be eligible for short-term or long-term incentive compensation, including, but not limited to, cash bonuses and stock program participation.
• This role includes paid personal time off and 14 paid company holidays.
• FanDuel offers paid sick time in accordance with all applicable state and federal laws.
