Senior iOS SDK Engineer - Mobile Observability

Job title: Senior iOS SDK Engineer
Location: 100% REMOTE

Salary: $130-170k/year + EQUITY!

Requirements: SDKs/ frameworks, Apple platform knowledge, APIs, debugging

 

Founded by one of the Scopely founders (~$5B exit in 2023 with 8 #1 games including MonopolyGo, Scrabble, Yahtzee, and Star Trek), we are a growth-stage Series B startup that's modernizing full-stack observability. We're backed by NEA, YCombinator, Greycroft, the founders of Testflight, Parse, and PagerDuty, and executives from AppDynamics, MoPub, Doordash, and Uber. 

 

We are the evolution of real-user monitoring (RUM) built on OpenTelemetry. Teams choose us because NO OTHER observability platforms are purpose built for frontend mobile and web teams while providing devops with the vital information they need to drive proactive & confident decisions. As we continue to grow, we need your help!

 

We're currently looking for a Senior iOS SDK Engineer to join our Mobile Observability team. This role focuses on building and maintaining a high-performance, open-source Swift SDK used across all Apple platforms. You'll work close to the OS to create instrumentation libraries for performance monitoring, telemetry, hang detection, and crash reporting, while collaborating with other platform teams and contributing to standards like OpenTelemetry. 

 

What you'll be doing:

• Design, build, and maintain a modular Swift SDK used across all Apple platforms.
• Implement core instrumentation features including crash reporting, hang detection, performance monitoring, and telemetry capture.
• Build resilient data pipelines for offline storage, batching, retries, and efficient delivery under strict mobile runtime constraints.
• Shape SDK architecture and API design, ensuring clarity, stability, and long-term backward compatibility.
• Debug complex platform issues involving threading, memory, lifecycle behavior, and OS/device fragmentation.
• Develop capture services for networking, user interactions, and system events using frameworks like MetricKit.
• Optimize performance across startup time, binary size, memory usage, and thread safety.
• Collaborate with cross-platform SDK teams (React Native, Flutter, Unity) to prevent downstream breaking changes.

• Strong production debugging skills across diverse devices and OS versions.
• API design experience, including versioning and long-term evolution.
• Understanding of binary compatibility and ABI stability.
• Comfort with Git and modern CI/CD pipelines.
• Openness to AI-assisted engineering workflows

Bonus skills:
