Cover Letter Sample

Dear Hiring Manager,

I am excited to apply for the Senior Android SDK Engineer position at RevenueCat. With over 5 years of experience in mobile development and a deep expertise in Android, Kotlin, and Jetpack Compose, I have a proven track record of shipping high-quality apps to the Google Play Store. I am particularly drawn to RevenueCat's mission of simplifying in-app subscriptions for developers and its remote-first culture.

In my previous role, I led the development of a widely-used SDK that processed millions of transactions, demonstrating my ability to build scalable, developer-friendly solutions. I am passionate about creating products that solve real problems and have a strong customer focus. I am also comfortable working across platforms and am eager to contribute to both Android and iOS SDKs.

I thrive in collaborative, fully-remote environments and am known for my proactive approach to identifying and fixing issues. I am excited about the opportunity to join a team that values shipping fast, owning outcomes, and maintaining balance. Thank you for considering my application. I look forward to the possibility of contributing to RevenueCat's growth.

Sincerely,

Possible Interview Questions

Can you describe your experience building and maintaining an Android SDK? What were the key challenges and how did you address them?

I have built an Android SDK for in-app purchases that handled thousands of transactions per day. Key challenges included ensuring backward compatibility, minimizing SDK size, and handling edge cases like network failures. I addressed these by using a modular architecture, thorough testing, and implementing retry logic with exponential backoff.

How do you ensure a great developer experience (DX) when building an SDK?

I focus on clear, comprehensive documentation, intuitive APIs, and minimal dependencies. I also provide sample apps and quickstart guides. I gather feedback from early adopters and iterate on the API design to reduce friction. Additionally, I ensure the SDK is easy to debug by providing detailed error messages and logging.

Walk me through how you would design a new feature for the Android SDK that requires server-side data. Consider performance, reliability, and ease of use.

I would start by defining the API surface with a focus on simplicity and consistency. For performance, I'd use caching strategies and asynchronous loading. For reliability, I'd implement retry mechanisms and fallback to cached data. I'd also provide both callback and coroutine-based APIs to cater to different coding styles. Finally, I'd write unit and integration tests.

Describe a time when you had to work across platforms (Android and iOS) on a shared feature. How did you handle the differences?

I worked on a feature that required consistent behavior across Android and iOS. I collaborated with iOS engineers to define a shared specification and used a common data format. For platform-specific implementations, I ensured the API design was idiomatic for each platform while maintaining the same logic. We used cross-platform tests to verify consistency.

How do you prioritize and decide what to work on when there are multiple features or bugs to address?

I prioritize based on customer impact and business value. I use data from crash reports, user feedback, and feature requests to identify the most critical issues. I also consider the effort required and dependencies. I communicate with the team and product manager to align on priorities and ensure we are working on the most important items first.

RevenueCat removes the headaches of building and scaling in‑app subscriptions. Since graduating from YC’s S18 batch we’ve grown into the default monetization platform for mobile: we’re in >40% of newly shipped subscription apps, we process $10B+ in annual purchase volume, and we help everyone from a solo dev in Brazil to the OpenAI mobile team understand and grow their revenue.
