Senior Mobile SDK Engineer

We’re looking for aSenior Mobile SDK Engineer to help design, build, and maintain production SDKs used inside customer mobile applications.

This role focuses on SDK development across:

• Android / Kotlin
• iOS / Swift
• React Native

You’ll work on features related to event tracking, consent handling, identity propagation, session lifecycle, payload delivery, and customer integrations.

This is not a traditional mobile app role. We’re looking for someone who understands how to build stable, scalable SDKs that external engineering teams depend on — including clean APIs, versioning, testing, documentation, and long-term maintainability.

Our environment is senior, product-focused, pragmatic, and collaborative. We value ownership, strong technical judgment, and engineers who can turn ambiguous requirements into production-ready solutions.

Responsibilities

• Build and maintain mobile SDK functionality across Android, iOS, and React Native
• Design reliable SDK APIs and integration workflows
• Implement features related to analytics, consent, session lifecycle, identity, and delivery behavior
• Handle edge cases such as offline mode, retries, batching, backgrounding, and app lifecycle events
• Collaborate with product and engineering teams to define and deliver scalable solutions
• Improve SDK quality through testing, demo apps, CI/CD, and documentation
• Participate actively in code reviews and technical discussions

Requirements

• 5+ years of software engineering experience
• Strong experience with Android (Kotlin/Java), iOS (Swift/Objective-C), and/or React Native
• Experience building SDKs, reusable libraries, or developer tooling
• Experience with analytics/event tracking SDKs or customer integrations
• Strong understanding of mobile lifecycle behavior and SDK architecture
• Comfortable working in startup environments with evolving priorities
• Strong communication and collaboration skills

Nice to Have

• Kotlin Multiplatform experience
• Experience with Segment, RudderStack, Snowplow, Tealium, or similar tools
• Experience with consent/privacy tooling (GDPR, CMP, etc.)
• CI/CD for mobile SDKs
• Experience in compliance-sensitive environments (SOC2, HIPAA, fintech, healthcare, etc.)

Ideal Background

• Mobile SDKs used by external customers
• Analytics, instrumentation, or customer data platforms
• Developer tooling and integration libraries
• Enterprise SaaS products with mobile integrations
