About Ditto:
Ditto is on a mission to unleash the full power of edge devices by removing all the
plumbing required to build amazing applications. We bridge the digital divide by
enabling real-time data synchronization—even when internet connectivity is limited or
non-existent. Our peer-to-peer technology is trusted by major customers like Chick-fil-A
and Delta Airlines, and we also work closely with the U.S. and allied military and first
responders on mission-critical connectivity solutions. As a fast-growing startup poised
for a future IPO, our team is globally distributed, and our core values are trust,
communication, and continuous improvement. We celebrate diversity and strive to
create a team that encompasses a wide range of backgrounds, skill sets, and
perspectives.
About the position:
As a Senior Android Engineer, you will play a pivotal role in building mission-critical
Android applications that support emergency responders and public sector customers in
the field. Your work will directly enable first responders, emergency management
teams, and defense personnel to maintain situational awareness and communicate
effectively during life-saving operations—even in environments with limited or no
connectivity. You'll craft robust user interfaces for handheld radios and situational
awareness software, working at the intersection of application development and low-
level hardware integration.
From day one, you'll own the full development lifecycle: building Android UI components
for critical field applications, integrating with peripheral devices like handheld radios,
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.
What you'll need:
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
showcases collaborative development and code quality
