About Us
 

We’re a fast-growing cleantech company building smart thermal energy storage systems that help buildings use cooling energy more efficiently.
Our platform combines IoT devices, edge computing, and cloud intelligence to support grid stability and significantly reduce CO₂ emissions.
In short: we build real hardware, connect it to the cloud, and make energy smarter 🌱
 

About the Role

We’re looking for a hands-on QA Engineer who cares about quality as much as we do.
You’ll be responsible for ensuring the reliability, performance, and stability of our full-stack IoT energy platform, from physical devices deployed at customer sites to cloud-based services and web applications.

This role is critical for scaling our platform and embedding quality deeply into both edge and cloud systems.
 

What You’ll Do

• Design, write, and execute test plans and test cases (manual & automated) for full-stack and IoT systems
• Build and maintain test automation frameworks (Python for backend, suitable tools for React frontend)
• Perform functional, regression, performance, and stress testing on systems handling real-time IoT data
• Collaborate closely with software engineers, product managers, and hardware teams to define quality standards
• Integrate automated tests into CI/CD pipelines to support continuous delivery
• Identify, document, and track bugs, working with R&D to ensure fast resolution
• Continuously improve QA processes and contribute to Agile best practices

What We’re Looking For

• BSc in Software Engineering, Computer Engineering, or a related field
• 3+ years of experience in Software QA, focused on web and cloud-based systems
• Strong experience designing and implementing automated testing frameworks
• Solid understanding of QA methodologies (Agile / Scrum / Kanban)
• Hands-on experience with Python for test automation
• Experience testing full-stack applications (React frontend + Python backend)
• Experience testing IoT or embedded-connected systems in production
• Good knowledge of SQL and database testing
• Experience integrating tests into CI/CD pipelines
• Familiarity with AWS, especially services like Lambda and IoT Core
• Strong communication skills and a collaborative mindset
   

Nice to Have

• Experience with performance and security testing
• Background in distributed systems or microservices
• Experience in hardware–software integrated environments
• Knowledge of Docker, Kubernetes, or containerized environments
• Experience in cleantech, energy, or sustainability-focused products
• Genuine interest in energy efficiency and sustainable technology
   

Why Join Us?

• Work on real-world systems that make a measurable environmental impact
• Be part of a multidisciplinary R&D team (software, hardware, IoT)
• Influence product quality at scale, not just “check boxes”
• Build technology that matters — not another CRUD app 🌍
