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
