Remote Senior iOS SDK Engineer

About the Role
We are looking for a

Senior iOS SDK Engineer

to join our Mobile Observability team, responsible for designing, building, and maintaining our

open-source Swift SDK

across Apple platforms (iOS, tvOS, watchOS, and macOS).

This is a

hands-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 OpenTelemetry.

What You’ll Do

Design, build, and maintain a

modular Swift SDK

used by developers across Apple platforms

Work on

crash reporting, hang detection, performance monitoring, and telemetry instrumentation

Build reliable mechanisms for

offline storage, batching, retries, and data delivery

under mobile runtime constraints

Contribute to

SDK 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 as

MetricKit

Optimize

startup performance, binary size footprint, memory usage, and thread safety

Coordinate with

cross-platform SDK teams (React Native, Flutter, Unity)

to ensure native SDK changes do not introduce downstream breaking issues

Collaborate on

OpenTelemetry alignment and upstream contributions

Partner with Product and Customer Success to incorporate

developer feedback

Basic Qualifications

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 in

production mobile environments

Familiarity with

API design, versioning, and SDK evolution

Understanding of

binary 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 to

AI-augmented engineering workflows

Preferred Qualifications

Experience with

Objective-C interoperability, runtime behavior, or method swizzling

Experience with

Swift macros

or

Swift Syntax

Familiarity with

OpenTelemetry or observability concepts

(traces, spans, logs)

Experience supporting

multiple Apple platforms

from a shared codebase

Familiarity with system-level frameworks such as

MetricKit

or

MXDiagnostic

Experience working in a

multi-SDK ecosystem

where platform changes affect cross-platform consumers

Contributions to

open-source projects

Experience supporting

external developers / SDK users

Additional Expectations
Interview & Collaboration
Our interview process includes live, synchronous conversations. Final stages may include an

in-person meeting

with a team member (travel may be required).

Engineering Workflow Evolution
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.

Role Focus
This role emphasizes

SDK / framework / platform engineering, not application UI development.

Work Culture & Travel
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.
