We’re currently seeking a passionate Senior QA Engineer for our mobile and IoT projects for a freelance cooperation. At the moment, we have a few open positions for our ongoing projects, which are heavily focused on IoT and mobile. As a freelancer working with intent, you'll have the chance to contribute your expertise to other IoT projects as well.
intent has over 10+ years of experience in helping to conceptualize, design, and build apps for IoT and connected devices. We're a software house that acts as a specialized think partner for products at the intersection of physical and digital (like wearables and IoT) - from net-new to products looking to enter a competitive and established niche. Some of our clients include Oura, BOSE, and McIntosh audio systems.
💎 Requirements:
At least 4 years of professional experience as a mobile tester.
Experience building testing approach or test cases from scratch – not only maintaining existing test suites
Experience with IoT testing (firmware, OTA, device connectivity, hardware–software interaction)
Familiarity with IoT protocols (e.g., Bluetooth, BLE, NFC, Wi-Fi, Thread)
Practical understanding of hardware workflows (e.g. firmware updates, pairing, resets, failure scenarios)
Experience with test case management tools (e.g. TestRail, Qase) and Atlassian tools.
At least B2 English skills (both written and spoken).
Self-reliance, responsibility for assigned tasks, and effective time management.
Keeping track of industry trends and proactively incorporating them into the company's technologies.
Engagement and team-play.
It’d be nice if you have:
Knowledge of the creation and maintenance of automated tests.
Practice in API testing (Postman preferred) and database testing.
Experience with web app testing and web-debugging proxy tools (e.g. Charles, Proxyman).
ISTQB Foundation (or higher) certificate.
Experience in working in Agile or Scrum environments.
What you'll do:
Compatibility Testing: Conduct compatibility testing to ensure seamless interoperability between various IoT devices, sensors, gateways, protocols, and platforms.
Functional Testing: Verify the functional correctness of IoT applications by testing features such as data collection, storage, processing, real-time monitoring, control, and integration with other systems.
Performance Testing: Evaluate the performance of IoT systems under different workloads, network conditions, and environmental factors to identify bottlenecks, latency issues, and scalability limitations.
Security Testing: Conduct thorough security assessments to identify and mitigate vulnerabilities in IoT devices, communication protocols, data transmission, storage, access controls, and authentication mechanisms.
Estimate your work.
Mentor less experienced team members to help them succeed and grow.
Participate in the requirement discussion meetings and daily calls, and provide feedback on inconsistencies and open issues.
Take part in knowledge sharing with other tech freaks.
🏝️ Perks and benefits:
100% remote work,
Flexible working hours with core hours between 10:00 and 18:00 CET, with some client meetings scheduled up to 20:00 CET (approx. 2 per week).
Moreover, if after a few months of working together, we're all on the same page, then definitely we’ll gladly invite you to join our internal intent team for long-term collaboration and you’ll enjoy all the benefits, such as paid holidays, paid sick leave, training budget, and much more!
Recruitment process:
A screening call with an HR person (45 mins).
A technical interview (60-90 mins).
Final feedback is received within a week after the interview.
Join us on this exciting journey where you'll have the opportunity to work on groundbreaking projects and shape the future of the IoT industry. Embrace the challenge, unleash your creativity, and be part of a team that is passionate about making a real impact in the world of technology 🦾
