Android Engineer

USB hardware, and network adapters, writing and maintaining FFI bindings between

Kotlin/Java and native C/C++ code, authoring comprehensive automated tests, and

streamlining CI/CD pipelines for reliable releases. You'll work directly with public sector

customers and field personnel to diagnose integration issues, conduct field testing to

ensure applications perform flawlessly under real-world emergency conditions, and

iterate quickly on feedback from those whose lives depend on your work.

You'll join a dedicated US-based team that values trust, clear communication, and

continuous improvement. In our async-first culture, your written design docs and code

reviews carry as much weight as face-to-face meetings, and occasional field

deployments and offsite gatherings bring us together to test our solutions in real-world

scenarios. If you're passionate about Android development that saves lives, low-level

systems integration, mentoring teammates on best practices, and delivering world-class

applications for mission-critical use cases, this is the role for you.

As a Senior Android Engineer, you will:

• Build life-saving Android applications: Design and implement intuitive,

responsive user interfaces for situational awareness software and handheld radio

integration using modern Android development practices, ensuring excellent user

experience and reliability in mission-critical field operations.

• Integrate with emergency response hardware: Work with handheld radios,

USB devices, network adapters, and other field equipment, implementing robust

communication protocols and handling edge cases in device connectivity for first

responders.

• Build and maintain native code integration: Implement safe, efficient Foreign-

Function Interface (FFI) bindings between Kotlin/Java and native C/C++ libraries,

adhering to best practices for memory management, threading, and error

handling.

• Support field operations: Travel occasionally to support testing and

deployment with emergency response teams, public sector customers, and field

personnel, ensuring applications perform reliably under real-world conditions.

• Ensure device and OS compatibility: Manage Android configurations and

platform quirks to deliver seamless application behavior across diverse device

architectures, Android versions, and hardware capabilities used in emergency

response scenarios.

• Develop comprehensive test suites: Write and automate unit, integration, and

end-to-end tests (including UI tests and native interop scenarios) to continuously

validate application functionality and guard against regressions in mission-critical

software.

• Integrate with CI/CD pipelines: Collaborate with the Release and QA teams to

embed your tests into continuous integration workflows, monitor release quality,

and iterate rapidly on customer feedback.

• Partner with field teams and customers: Triage and resolve customer-

reported issues from emergency response personnel, debug edge-case failures

in field deployments, and feed learnings back into product and engineering

roadmaps.

• Mentor and evangelize best practices: Share your expertise in Android

development, native code integration, and hardware interfacing through design

reviews, brown-bags, and one-on-one coaching to level up the entire team.

• 4+ years of professional software development experience: Proven track

record of delivering production-quality Android applications in a team setting.

• Deep expertise in Android development: Hands-on experience building

Android applications with Kotlin and Java, including modern UI development with

Jetpack Compose or Views, understanding Android SDK architecture, lifecycle

management, and performance optimization.

• Strong C/C++ programming skills: Proficiency in C or C++ for native Android

development, with experience using JNI/NDK to bridge between Kotlin/Java and

native code in an FFI context.

• Experience with hardware peripherals: Practical experience interfacing with

USB devices, network adapters, or other hardware peripherals from Android

applications.

• Willingness to travel for field testing: Ability to travel occasionally to support

testing, deployment, and training with customers and field personnel in various

locations.

• Debugging and diagnostic chops: Ability to read native stack traces, interpret

logs and memory dumps, and troubleshoot issues across the Android stack from

UI to native code.

• Test automation and CI/CD fluency: Experience designing and implementing

unit, integration, and UI tests, and integrating them into automated build and

release pipelines.

• Excellent communication skills: Strong written and verbal communication to

thrive in an async-first, distributed team-drafting clear design docs, participating

in code reviews, and coordinating with customers and stakeholders.

Nice to Haves:

• Experience with Kotlin Multiplatform (KMP) for cross-platform mobile

development

• Familiarity with Rust programming language and basic understanding of systems

programming concepts

• Experience with Voice over IP (VoIP), radio communications systems, and/or

amateur radio operator experience

• Networking knowledge: Understanding of TCP/IP stack, network protocols,

REST, TCP/UDP, QUIC, Bluetooth Low Energy, and other communication

protocols

• Experience with build and release automation: Proven ability to publish Android

applications and configure Gradle and CI pipelines for distribution

• Track record of open-source contributions: Demonstrated involvement in Android

projects-whether through libraries, tooling, or community support-that
