Nice to Have

• Experience developing and maintaining production web applications.
• Experience with cloud services and mobile analytics platforms.
• Familiarity with Agile/Scrum methodologies.
• Experience publishing and maintaining applications on Google Play.

What We Value

• Deep expertise in Android development combined with a willingness to learn and grow beyond a single technology stack.
• Engineers who take ownership and contribute wherever they can create the most value.
• A collaborative mindset focused on knowledge sharing and reducing single points of failure.
• Curiosity, adaptability, and a passion for continuous improvement.
• Commitment to building high-quality products and exceptional user experiences.
