About the Role

We are looking for a talented and experienced Senior Android / Frontend Developer to join our growing engineering team in Plovdiv. In this role, you will be responsible for designing, developing, and maintaining high-quality Android applications that deliver exceptional user experiences.

You will work closely with Product Managers, Designers, QA Engineers, Backend Engineers, and fellow developers to create innovative solutions and drive technical excellence across the organization.

We expect this role to involve both Android and web development, and we are looking for an engineer who enjoys working across platforms and expanding their technical expertise. Our goal is to build a versatile engineering team with shared ownership and broad technical capabilities, rather than creating single-technology specialists.

Lead technical design, architecture discussions, and technical decision-making for Android applications while contributing to cross-platform architecture across mobile and web.
Collaborate with Product Managers, UX/UI Designers, and fellow engineers to define and implement new features.
Contribute to the development and maintenance of Angular-based web applications.
Perform code reviews, provide constructive feedback, and promote engineering best practices to ensure high code quality, maintainability, and technical excellence.
Troubleshoot, debug, and resolve performance, scalability, and reliability issues while ensuring application quality through unit testing, integration testing, and continuous improvement practices.
Stay up to date with emerging technologies, frameworks, and industry trends.
Mentor junior developers and contribute to a collaborative, knowledge-sharing engineering culture.

Requirements

5+ years of professional experience in Android application development.
Strong proficiency in Kotlin and solid understanding of Java.
Experience with Android SDK, Jetpack components, and modern Android architecture patterns (MVVM, Clean Architecture).
Strong understanding of RESTful APIs and integration with backend services.
Experience with Git and modern CI/CD workflows.
Familiarity with unit testing, automated testing, and quality assurance practices.
Knowledge of mobile application performance optimization and security best practices.
Willingness and ability to contribute to Angular-based web applications as part of day-to-day development responsibilities.
Demonstrated ability and enthusiasm to learn new technologies and work effectively across multiple technology stacks in collaboration with cross-functional teams.
Excellent problem-solving and analytical skills.
Strong communication skills and the ability to work effectively in a collaborative team environment.
Fluent in English, both written and spoken.

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.

If you are passionate about Android development, enjoy solving complex technical challenges, and are excited by the opportunity to contribute across both mobile and web platforms, we would love to hear from you.
