About the Position

We are seeking a Senior SDET with 5+ years in test automation and E2E coverage for web UI and backend services to join our remote team.

Responsibilities

Design and build the automation stack for the new platform: UI + API, structure, conventions, reporting.
Cover core platform flows: client env provisioning, proxy routing, betting integration, later paths.
Integrate automation into GitLab CI/CD: smoke on deploy, regression on release, clear pass/fail gates per client env where needed.
Build API and integration tests for backend services, client-facing APIs, WS/gRPC where the product uses them.
Set up stable test execution: parallel runs, flaky test handling, useful failure output (logs, traces, screenshots).
Own test data strategy across client dev environments: users, config, DB fixtures, tenant isolation.
Work with architects on testability: mocks/stubs for external betting/casino systems, env topology, debug hooks.
Work with BAs and product on scope and AC; turn business flows into automatable scenarios.
Support the current QA: pairing, reviews, unblocking, shared ownership of quality on the product.
Prepare groundwork for the next engineers in test automation: docs, patterns, backlog, review standards.
Investigate production-like issues in test: proxy, network, env drift, client-specific config bugs.
Propose improvements to automation and release process; do not wait for a fully written spec on every item.

Requirements

5+ years in test automation / SDET, with strong E2E coverage for web UI and backend services.
Experience building or rebuilding an automation framework from early stage, not only maintaining an existing one.
Strong Python for test automation (production-quality test code, reviews, structure).
UI automation with Playwright, Cypress or Selenium; stable patterns, not only record-and-play.
API automation: REST, WebSockets, gRPC; microservices and contract-style checks.
GitLab CI/CD (or similar): embed smoke/regression in pipelines, quality gates, release checks.
Solid web fundamentals: HTTP, status codes, sessions, payloads, real-time updates over WS.
Debug failures using logs, browser devtools, network traces, proxies (Charles/Fiddler), CI artifacts.
Test data and environment setup: isolated runs per env/client, DB/state handling, config per tenant.
Work with architects and BAs: clarify flows, testability, mocks, acceptance criteria before coding tests.
Mentor QA engineers: MR reviews, onboarding, help manual QAE move into automation.
Comfortable in high-change greenfield work: unclear scope at start, lots of discovery with engineering and product.

Nice to Have

Sportsbook, betting, iGaming, casino or real-time fintech background.
Knowledge of bet placement, settlement, cashout, balances, live/in-play flows.
Playwright as primary UI tool.
Load/performance testing (k6, JMeter, Locust) for APIs under traffic.
Docker/K8s for test envs and runners.
Grafana, Prometheus, ELK, ReportPortal for test health and failure analysis.
Browser/device matrix based on real usage data.
LLM-assisted test maintenance or synthetic data (as a helper, not a replacement for design).
Self-hosted Playwright/Selenium grids or custom runner pools.
