About the role

  • Own the E2E EUT Strategy: Define and evolve the end-to-end user testing framework for integrated products (Hardware + Software), establishing clear entry/exit criteria and quality gateways for all releases.
  • Closely integrate with the overall Firmware release process: to help us release faster and in higher quality.
  • Bridge Multi-Disciplinary Teams: Act as the primary liaison between Software, Electronics, and Mechanical Engineering teams to ensure that the interplay between firmware, sensors, and physical materials meets operational expectations.
  • Manage and collaborate with external partners such as testing agencies and other external quality vendors.
  • Validate Product Integrity: Translate complex product requirements into actionable, real-world test scenarios that validate not just software performance, but the functional reliability of electronics and physical mechanics in a customer’s environment.
  • Execution Leadership: Oversee the planning, scheduling, and execution of UAT cycles for new product launches and updates, ensuring they are completed on time without compromising the depth of testing across all components (e.g., connectivity, material durability, and mechanical response).
  • Defect Advocacy & Triage: Lead the cross-functional defect triage process, using business judgment to prioritize fixes for software bugs, mechanical inconsistencies, or electronic failures before go-live.
  • Process Innovation: Drive the modernization of EUT through structured feedback loops and the selection of best-in-class testing tools to accelerate the path to production for both digital and physical components.
  • User Training & Support: Recruit and support customers or business users participating in testing, providing the structured scripts and clarity they need to provide high-quality functional feedback on the total product experience.
  • Strategic Reporting: Provide structured, data-driven insights to senior leadership on product readiness, technical risks (across SW and HW), and overall quality of the release.
  • Environment & Data Management: Collaborate with DevOps, Quality assurance and Hardware Engineering to ensure stable testing environments that accurately simulate the customer’s home ecosystem, including representative hardware samples and secure test data.

Requirements

  • 8+ years of experience in Quality Assurance (QA) or User Acceptance Testing (UAT), with a proven track record in integrated hardware/software product delivery (e.g., IoT, consumer electronics, or smart toys).
  • Strategic Mindset: Proven ability to design end-user testing strategies that focus on functional validation and high-quality delivery standards for complex, multi-component products.
  • Technical Versatility: Familiarity with the unique testing challenges of software-controlled hardware, including firmware updates, electronic connectivity, and mechanical stress testing from a user's perspective.
  • Strong Communicator: A talent for "translating" between technical developers, mechanical engineers, and non-technical business users to align on acceptance criteria.
  • Agile Expertise: Deep familiarity with Agile/Scrum methodologies and how to integrate hardware testing cycles into rapid digital delivery timelines.
  • Analytical Rigor: Proficiency with test management tools (e.g., JIRA, TestRail, Zephyr) and a data-driven approach to reporting on defect trends across both physical and digital domains.
Benefits
  • Mobility: Choose the option that suits you best - a Deutschlandticket (public transport ticket) for unlimited mobility, a monthly contribution for an office parking space, a leasing bicycle, or a remote work subsidy.
  • Enhanced Security: Benefit from subsidies for company pension plans, occupational pension schemes, and occupational disability insurance.
  • Rest & Time Off: Enjoy 30 days of paid annual leave as well as three additional days off such as Rosenmontag, Christmas Eve, and New Year's Eve. After one year of employment, you can also use up to 10 "toniecation days" (unpaid leave days).
  • Continuous Learning: Benefit from our internal and external training opportunities as well as an individual learning budget to continuously expand your knowledge.
  • Language Learning & Relaxation: Improve your communication skills with the language learning app Babbel and find relaxation through our access to the meditation app Calm.
  • Discounts: Benefit from attractive discounts on our entire range of tonies products.
