As a (Senior) Quality Assurance Engineer (f/m/d) in our Games Production Team, you will ensure the quality, functionality, and security of our growing portfolio of slot games, instant-win games, and scratchcards. Your work plays a critical role in delivering a reliable and enjoyable experience for players, while also upholding regulatory compliance and safeguarding the integrity of our gaming platform. You’ll help establish and continuously improve QA practices that make our games robust, testable, and ready for release in regulated markets.   YOUR TASKS: * Design, build, and maintain automated test suites tailored for slots, instant-win games, and scratchcards, while performing manual testing during development and release phases. * Define and evolve test strategies that address the unique challenges of game testing — including animations, UI responsiveness, game state complexity, and random outcomes. * Collaborate with Game Developers, Game Designers, and Artists in a creative and agile environment. * Maintain structured test documentation, including test plans, bug reports, and regression checklists. * Execute cross-device and cross-browser testing to validate performance, consistency, and responsiveness across platforms. * Ensure compliance with regulatory standards, and support certification-related QA tasks such as preparing test evidence or assisting with audits for relevant jurisdictions (especially Germany). Prior knowledge is a plus, but can also be acquired on the job. * Advocate for a player-first quality mindset, helping the team prevent critical issues that could impact the game experience or platform reputation.   WHAT YOU OFFER US: * Practical experience in testing online games, ideally including slot games, scratchcards, or instant-win mechanics. iGaming industry experience is highly desirable. * A solid understanding of game testing challenges, including randomness, animations, math models, and edge-case scenarios. * Familiarity with basic probability and mathematics used in slot game design (e.g., RTP, volatility, win frequency) is a strong plus. * Proficiency with Playwright and TypeScript or similar frameworks for frontend automation. * Experience in manual exploratory testing—you know how to think like a player and uncover hidden issues. * Understanding of QA standards and compliance requirements for regulated markets (e.g., Germany, UK, MGA). * Strong collaboration skills and a proactive mindset—you’re ready to take ownership of quality in a fast-moving team. * Strong English skills are required for collaboration within the team. * Fluency in German is a nice-to-have.   WHAT WE OFFER: * State-of-the-art technologies and an agile environment (Check our Tech Radar: https://lotto24.github.io/tech-radar/) * A modern, dynamic culture grounded in the success of a leading-edge e-commerce company. * A talented team of ambitious, like-minded colleagues where your knowledge and ideas truly make an impact. * Ongoing personal growth, supported by an annual development budget of €1,500 to invest in your professional development. * Trust and autonomy, no micromanagement, just confidence in your ability to deliver and excel. * Flexible work options with a hybrid setup focused on results. * Unlimited vacation days in addition to your yearly 30-day vacation allowance. * Opportunity for workations abroad using our WorkFlex tool. * Monthly mobility allowance of €30 to use on the mobility option of your choice (e.g., the Deutschlandticket), plus access to a company bike leasing program. * Company pension scheme, provided in partnership with Degura, to support your future financial security. * Subsidized EGYM WELLPASS membership, with a contribution of only €25 per month, giving you access to a wide range of gyms and sports options across Germany. * Quarterly company events, along with regular team activities and informal gatherings, a favorite being our Healthy Tuesday lunches or Treat Thursdays in the office!   Sounds exciting? Great! We're looking forward to receiving your online application.

DEINE MISSION We are looking for an experienced electronics engineer to help mature our electronic systems toward reliable and qualification-ready space hardware. You will join projects with existing architectures and prototype designs. Your role will be to assess these designs critically, identify gaps in reliability, EMC, verification, component selection, and failure behaviour, and drive the necessary improvements. This is a senior hands-on engineering position without immediate personnel responsibility. As our electronics team grows, the role can develop toward broader technical responsibility. What You Will Do * Assess existing electronic architectures and designs with regard to requirements, robustness, failure behaviour, testability, and future qualification needs. * Identify technical risks and recommend practical design improvements. * Develop and review mixed-signal and power electronics, including sensor interfaces, power distribution, protection circuits, monitoring, and actuator or valve drivers. * Translate system requirements into hardware requirements, interface definitions, design assumptions, and verification objectives. * Perform circuit and subsystem analyses such as worst-case analysis, derating assessment, and electrical stress analysis. * Perform electronics-related FMEA/FMECA activities and provide technical input to system-level failure and reliability analyses. * Plan and execute structured hardware bring-up, debugging, robustness testing, and fault-injection testing. * Prepare EMI/EMC pre-compliance and formal test activities, including test objectives, configurations, expected results, and acceptance criteria. * Select components with consideration for electrical performance, availability, lifetime, derating, failure behaviour, and future qualification constraints. * Define electrical PCB layout constraints and review layouts for grounding, return paths, EMC, power integrity, signal integrity, and testability. * Document important requirements, design decisions, analyses, and verification results. * Work closely with junior electronics engineers as well as software, control, mechanical, test, and system engineers. DEIN PROFIL * A degree in electrical engineering or a comparable technical background. * Several years of hands-on experience developing and testing electronic hardware. * Experience with complete electronic subsystems rather than only individual circuit blocks. * Experience in a high-reliability, mission-critical, or safety-relevant environment such as aerospace, automotive, medical, railway, industrial safety, or space. * Strong schematic design and circuit analysis skills in mixed-signal or power electronics. * A solid understanding of component tolerances, temperature effects, electrical stress, protection concepts, and electronic failure behaviour. * Practical laboratory experience with hardware bring-up, debugging, and structured testing. * The ability to work from requirements through design and analysis to verification. * Strong written and spoken English. Strongly Preferred * Practical experience with one or more of the following: * EMI/EMC design and test preparation * FMEA, DFMEA, or FMECA * Worst-case circuit analysis * Derating or electrical stress analysis * Requirements-based verification * Fault-injection or robustness testing * Design reviews in a regulated or structured development environment We do not expect candidates to be specialists in every discipline listed above. We are looking for someone who understands how reliable electronics are developed and can apply structured engineering judgement to unfamiliar problems. Nice to Have * Experience with space hardware, ECSS, EEE components, environmental testing, or qualification planning. * Experience with sensor electronics, solenoids, valves, motors, DC/DC conversion, or power distribution. * Experience with Altium Designer or a comparable ECAD environment. * Experience with SPICE-based simulation. * Familiarity with Python, MATLAB, or similar tools for analysis and test automation. * Experience supporting or mentoring less experienced engineers. WIR BIETEN * Meaningful technical responsibility for hardware used in real space systems. * The opportunity to mature existing prototypes into robust, qualification-ready designs. * Close collaboration across electronics, software, control, mechanics, test, and systems engineering. * The opportunity to influence our electronics development, verification, and review processes as the team grows. * Permanent full-time position with flexible working hours and 30 days of annual leave. * Bike leasing, EGYM Wellpass, Deutschlandticket subsidy, professional development opportunities, company events, and complimentary beverages.
