Overview
As a Senior Mobile Engineer, you'll contribute to a multi-platform app built on Kotlin Multiplatform, shipping features across Android, iOS, and additional targets from a shared codebase. You'll own complex work end-to-end, write code that sets the quality bar for the team, and help shape architecture decisions in a fast-moving product environment. Our engineering strategy centers on KMP and Compose Multiplatform to deliver high-quality, consistent experiences across platforms — and the engineers who build it are expected to help keep that bar high.
Responsibilities

Implement features across core product domains — connecting Compose Multiplatform UI to shared business logic through clean MVI state management
Contribute to a layered, multi-module architecture, respecting module boundaries and shared platform contracts
Partner with shared platform teams to implement against declared interfaces, keeping app-specific logic cleanly separated from shared platform concerns
Collaborate with product, design, and QA to deliver reliable, pixel-accurate experiences across multiple platform targets
Write testable, well-structured Kotlin leveraging coroutines, flows, KSP-based codegen, and dependency injection patterns consistent with the team's standards
Conduct thorough code reviews, maintaining module boundary discipline and build system conventions
Participate in the on-call rotation, helping diagnose and resolve issues across platforms
Mentor junior engineers and contribute to a culture of continuous learning on the team

Strong Kotlin proficiency — coroutines, flows, idioms, and best practices — with the ability to apply and share these effectively across the team
Experience with Kotlin Multiplatform — comfortable developing and scaling shared business logic in a multi-module KMP codebase
Hands-on experience with Compose or Compose Multiplatform, building design-system-compliant UI across platform targets
Proficiency in Gradle multi-module projects, including convention plugins and dependency management
Experience with CI/CD pipelines and automated mobile testing practices
Comfortable working across shared platform and library boundaries — implementing against declared interfaces without leaking platform-specific logic into shared modules
Clear communicator able to articulate technical decisions to peers, product, and design stakeholders
Agile/SCRUM experience with a track record of consistent, quality delivery
Team-first mentality with a drive to raise the bar continuously
Bonus
Compose Multiplatform experience across Android, iOS, desktop, and wasm targets

We are seeking a
Senior Mobile Engineer
to take ownership of the Mattermost mobile experience for teams working in defense, intelligence, and critical infrastructure. Our users operate in DDIL environments where connectivity may be disconnected, denied, intermittent, or limited, security is non-negotiable, and the software they depend on has to keep working.
Our mobile app is primarily React Native and TypeScript today, with native iOS and Android integrations. Your immediate focus will be making that experience more reliable and performant. Over time, you'll also help shape the next generation of our cross-platform mobile architecture.
You'll work hands-on across application and native layers, partner closely with platform and feature teams, work directly with customer-facing teams on field reports from constrained environments, and help raise the bar for how we observe, diagnose, and build mobile software.
Responsibilities
Reliability and Performance
Architect the app for DDIL and other constrained network environments
Improve data and functional reliability across connection lifecycle, synchronization, recovery, and failure scenarios
Own crash-free and release-health outcomes, using telemetry to proactively identify regressions and drive them through diagnosis to resolution

Build within mobile distribution and device-management constraints, including App Store, enterprise and MDM deployment, AppConfig, and Intune MAM
Diagnose production issues from native traces, telemetry, device profiling, and sparse field logs
Make architecture recommendations that balance near-term delivery with the long-term direction of the mobile platform
Craft and Delivery
Mentor engineers on mobile architecture, reliability, performance, and platform best practices
Uphold security and compliance standards required by government and enterprise customers
Contribute to the open-source codebase
Use AI coding tools effectively, applying strong engineering judgment to increase output without compromising reliability or quality
What We Are Looking For
We care about what you've built and the problems you've solved — not how long you've been building. If you have strong outcomes to speak to in mobile engineering, we want to hear from you.
Required:
Deep expertise in iOS or Android development, with strong working knowledge of the other platform
Strong understanding of mobile architecture, platform SDKs, lifecycle constraints, and networking fundamentals
