Senior iOS SDK Engineer

United States or Canada, US Remote - Pacific Time

We are looking for aSenior iOS SDK Engineer to join our Mobile Observability team, responsible for designing, building, and maintaining ouropen-source Swift SDKacross Apple platforms (iOS, tvOS, watch

OS, and macOS).

This is ahands-on, SDK-first role focused on building high-performance instrumentation libraries embedded in customer applications. It is ideal for someone who enjoys working close to the platform, solving difficult edge cases, and designing APIs that other developers rely on.

You’ll work on performance monitoring, telemetry capture, hang detection and crash reporting, all designed for minimal overhead and maximum reliability. You’ll collaborate across platform teams and contribute to evolving observability standards such as Open Telemetry.

• Design, build, and maintain amodular Swift SDKused by developers across Apple platforms
• Work oncrash reporting, hang detection, performance monitoring, and telemetry instrumentation
• Build reliable mechanisms for offline storage, batching, retries, and data delivery under mobile runtime constraints
• Contribute toSDK architecture, API ergonomics, and backward compatibility
• Design and evolve APIs with a focus on stability, clarity, and long-term compatibility
• Debug complex issues across devices, OS versions, and app environments, including threading, memory, and lifecycle challenges
• Develop and maintain capture services for networking, user interactions, and system events, leveraging frameworks such asMetric Kit
• Optimize startup performance, binary size footprint, memory usage, and thread safety
• Coordinate withcross-platform SDK teams (React Native, Flutter, Unity) to ensure native SDK changes do not introduce downstream breaking issues
• Collaborate onOpenTelemetry alignment and upstream contributions
• Partner with Product and Customer Success to incorporate developer feedback

• Strong proficiency in Swift, including async/await, structured concurrency, and protocol-oriented design
• Experience building or maintaining
  
  SDKs, frameworks, or developer-facing libraries
• Deep understanding of Apple platform runtime constraints:memory, threading, lifecycle, startup performance
• Experience debugging issues inproduction mobile environments
• Familiarity with
  
  API design, versioning, and SDK evolution
• Understanding ofbinary compatibility and ABI stability
• Strong advocate for testing, reliability, and code quality
• Excellent verbal and written communication skills
• Experience using
  
  Git and modern CI/CD workflows
• Openness toAI-augmented engineering workflows

• Experience with Objective-C interoperability, runtime behavior, or method swizzling
• Experience with Swift macrosor
  
  Swift Syntax
• Familiarity with
  
  Open Telemetry or observability concepts(traces, spans, logs)
• Experience supporting multiple Apple platforms from a shared codebase
• Familiarity with system-level frameworks such asMetricKitorMXDiagnostic
• Experience working in amulti-SDK ecosystem where platform changes affect cross-platform consumers
• Contributions toopen-source projects

Our interview process includes live, synchronous conversations. Final stages may include anin-person meeting with a team member (travel may be required).

We work in an environment where

AI-assisted tools are increasingly part of engineering workflows.

We value pragmatic, thoughtful use of these tools and expect candidates to be comfortable discussing their experience and perspective.

This role emphasizes SDK / framework / platform engineering, not application UI development.

We are a remote-first company. This role is open to candidates located anywhere in the U.S. or Canada. We believe in regular in-person connection and expect travel for team off-sites and collaboration to be approximately once per quarter.

The cash compensation for this role is in the $130k-170k range. In addition to base comp for this role, we offer equity in the form of options, a variety of benefits, and the opportunity to grow in an exciting and collaborative environment. Actual compensation may vary based on level, experience, and skillset as assessed in the interview process.
