Senior Android Developer

Velotio Technologies is a product engineering company working with innovative startups and enterprises. We have provided full-stack product development for 110+ startups across the globe, building products in the cloud-native, data engineering, B2B SaaS, IoT & Machine Learning space. Our team of 400+ elite software engineers solves hard technical problems while transforming customer ideas into successful products.

We are seeking a Senior Android Developer with expertise in building Android software development kits (SDKs) to join our team. In this role, you will lead the end-to-end development of Android SDKs that will be integrated by other developers into their applications.

The ideal candidate is an expert in Kotlin and Java, has a strong grasp of Android architecture and design patterns, and has a proven track record of publishing and maintaining Android libraries. You will drive the SDK's design, implementation, documentation, and long-term maintenance, ensuring high performance, reliability, and backward compatibility. This is a senior-level technical role that requires hands-on development, strategic thinking, and the ability to collaborate effectively in a hybrid work environment.

Requirements

• Design & Build: Craft modular, high-performance Android SDKs in Kotlin (and supportive Java) that are easy to integrate and extend.
• SDK Lifecycle Ownership: Own the full SDK development lifecycle including planning, development, testing, and release. Manage versioning (semantic versioning) and long-term maintenance for continuous improvement of the SDK.
• Release Management: Publish artifacts to Maven Central / JitPack, manage semantic versioning, changelogs, and ensure backward compatibility.
• Performance & Reliability: Profile, benchmark, and optimize for low memory, battery, and network usage across a wide device matrix.
• Security & Compliance: Implement encryption, token handling, and privacy-first data practices - crucial for payment and analytics use cases.
• Documentation & Samples: Produce clear guides, Javadoc/KDoc, and sample apps so external teams can get started in minutes.
• Collaboration: Partner with product, backend, and QA to define features, automate CI/CD (GitHub Actions/Bitrise), and drive code reviews.

You will enjoy this role if you...
