Overview

Hard Rock Digital is a fiercely focused team working to become the best online sportsbook, casino, and social gaming company in the world. We're building a deeply curious team with a passion for learning, operating, and building new products and technologies for millions of consumers. We're customer-obsessed — we care about each customer interaction, experience, behavior, and insight, and strive to ensure we're always acting authentically.

Rooted in the kindred spirits of Hard Rock and the Seminole Tribe of Florida, Hard Rock Digital taps a brand known the world over as the leader in gaming, entertainment, and hospitality. We're taking that foundation of success and bringing it to the digital space - ready to join us?

What’s the position?

Unlike a traditional feature-team QA role, you will own quality across the entire platform rather than a single feature area, acting as a key safeguard before our releases reach millions of customers. You will lead manual regression testing during our regression windows, shift that regression earlier into our integration environments, uncover device, OS and hardware specific issues, and partner with feature teams to strengthen their test coverage. The role requires an individual who’s dedicated to the customer’s experience, able to clearly voice and document issues and concerns within their testing focus and who is a self-starter with a strong sense of ownership. You will be responsible for the quality, scope and timeliness of all your deliverables. We will be reliant on your skills and your passion and accountability for all aspects of your work.

Key Responsibilities:

• Plan and execute manual regression testing of our web and mobile applications during scheduled regression windows, ensuring the quality and stability of every platform release

• Uncover defects specific to devices, device types, operating systems and hardware across iOS,

• Android and web, including testing against OS betas and newly released devices

• Test real-world conditions such as poor or switching networks, interruptions, app backgrounding, permission changes and biometric login edge cases

• Perform usability and accessibility testing to ensure an intuitive and inclusive customer experience

• Validate jurisdiction-specific and regulated functionality, including geolocation, KYC and age verification, responsible gaming controls, and payments and wallet flows

• Partner with feature teams by facilitating and participating in Bug Bashes and Feature Testing Sessions

• Retroactively analyse work delivered by feature teams to identify gaps in test specifications and test cases, and drive those gaps to closure

• Own the health of the manual regression suite by pruning obsolete cases, consolidating duplicates and keeping coverage risk-prioritized

• Shift testing left by running regression and structured exploratory testing charters against high-risk areas of the platform in our integration test environments, continuing that coverage during regression windows

• Perform post-release production verification, including validation of app store builds, upgrade paths and phased rollouts

• Perform readiness testing ahead of high-traffic sporting events across live betting, odds updates, cashout and bet slip functionality

• Help curate our device lab and device coverage matrix, using customer usage data to prioritize devices, OS versions and form factors

• Report, triage and manage defects, providing clear reproduction steps supported by logs, video and device details

• Perform root cause and escaped defect analysis on production issues, and feed findings back into regression coverage

• Reproduce customer-reported issues escalated from app store reviews or Player Support, turning vague reports into actionable defects

• Work closely with QA Automation Engineers to identify and prioritize stable, repetitive, high-value regression cases for automation

• Use AI tools to speed up your understanding of our platform and to accelerate test case design, gap analysis and defect reporting

• Track and report quality KPIs such as defects found per regression window, escaped defects and regression cycle time

• Mentor and provide guidance to members of the QA team

• Collaborate with developers, product owners and other stakeholders to understand requirements and provide input on testability and quality aspects

• Stay updated on industry best practices, emerging technologies and testing tools to continuously improve the efficiency and effectiveness of the QA process

• Learn our applications inside and out, and become a subject matter expert
