Job description

We’re looking for a Senior 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 β€” 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
