About your role

The User Validation Engineer serves as the primary advocate for the end user throughout the product development and market lifecycle with the goal to deliver high-quality products at launch and monitor the product experience that delight our users until the end of support of our products. 
Your focus is to bring validation forward in the NPI, validating concept designs, low-fidelity prototypes, setting dogfooding, alpha, and beta testing programs and providing user feedback to facilitate achieving quality targets. 

Key Responsibilities & Objectives

Your Key Responsibilities

• Review early hardware and software concepts alongside Product Managers to identify usability risks early during concept and pre-development stages, defining explicit experience KPIs and acceptance criteria and metrics for every gate. You will support your insights by conducting user testing on among others, non-functional mockups and software user flows to validate design assumptions early.
• Define prototype, dogfooding, alpha, beta and regression test plans and scripts that support validation during development of software updates and hardware phases (EVT, DVT, PVT). 
• Manage end-to-end beta program execution on our dedicated beta platform (including crash reporting tools), driving cohort recruitment, segmentation & tester engagement and future scale strategy. You will own prototype device distribution, samples software deployment, security protocols, and strict NDA compliance. Administer feedback collection tools, crash-reporting software, and telemetry collection systems.
• Synthesize qualitative feedback and quantitative telemetry into actionable reports for other teams and where needed you will translate your insights technical Jira. 
• Translate post-launch market insights, customer support trends, and field reports into usability investigation testing. Build feedback loop with Product Managers and QA to address UX and functionality gaps in future software updates and future products.

Your Key Objectives

• Drive development excellence and surface quality risks by establishing an early validation process and producing usability and user preference reports based on data that support product decisions at critical development milestones.
• Scale our user testing community, by nurturing an engaged and representative beta tester pool that delivers continuous, high-value field feedback on unreleased products and software updates.
• Translate usability market insights into a software and physical prototype testing strategy to analyze user experience and establish user experience quality targets for future products.

Your Skills & Experience

• 7 years experience operating in user validation, QA, UX research, or technical program management for consumer electronics (hardware and software).

• Advanced experience working within Jira environments.
• Practical proficiency with research tools (e.g., UserTesting, Maze) 
• Strong understanding of how to set up an empirical study that yields statistically relevant results.
• Experience validating connected devices that rely on complex multi-layer architecture (e.g., hardware + wireless connection + mobile app.
• Deep familiarity with consumer electronics stage-gate processes (Concept, EVT, DVT, PVT, MP) and firmware deployment strategies.
• Expertise in applying early-stage testing methodologies, such as paper/3D prototype validation, bench-test scenario scripting, and low-fidelity user flows.
• You are able to work independently and as part of a team.
• You have excellent written and verbal communication skills in English.
