Senior Software Engineer, PubSec

About Ditto:

Ditto is redefining how data moves at the edge. Our mission is to make it seamless for developers to build resilient, real-time applications, regardless of network conditions. Whether you're in a stadium, airplane, or remote military base, Ditto's peer-to-peer sync engine ensures devices stay connected and data stays consistent, even without internet. With more than $145 million in funding and trusted by organizations like Chick-fil-A, Delta Airlines, and the U.S. military, Ditto powers mission-critical experiences across aviation, retail, travel, hospitality, defense, and more. As a globally distributed, fast-growing startup, we're committed to building a diverse and inclusive team that reflects the wide range of perspectives needed to solve the world's hardest connectivity problems.
About the Position

As a Software Engineer, you'll design, build, and ship software that integrates our platform's data synchronization capabilities directly into the tools and environments where our users work. You'll own meaningful features end-to-end - from architecture and implementation through deployment - with a particular focus on mobile and integration work that meets users where they are.

You'll also serve as a key feedback loop into our core product engineering team, translating what you learn from real-world usage into clear technical insights and product requirements. This role is well-suited to a highly adaptable problem-solver who is comfortable moving fast, navigating ambiguity, and figuring things out quickly to deliver reliable software.
Key Responsibilities

• Develop and Extend ATAK Plugins: Lead the design, development, and field deployment of custom ATAK (Android Team Awareness Kit) plugins that integrate our platform's data synchronization capabilities directly into the warfighter's primary situational awareness tool.
• Build Android-Native Integrations: Architect and develop performant Android applications and services that run on tactical end-user devices, ensuring reliable operation in disconnected, intermittent, and low-bandwidth (DIL) environments.
• Design Integration Architectures: Own the end-to-end integration design between our platform and the broader TAK ecosystem, defining data contracts, API boundaries, and synchronization patterns that enable seamless interoperability with third-party systems and services.
• Solve Problems in Real-Time: Act as the first line of technical defense, rapidly diagnosing and resolving application, integration, and data-flow issues as they arise on end-user devices in live operational environments.

What You'll Need

• Clearance Eligible Requirement: Must be eligible to obtain a Secret clearance (Due to federal security clearance requirements, U.S. Citizenship is strictly required for this role).
• 5+ years of experience in software engineering, including hands-on experience building, shipping, and maintaining production applications. You should be comfortable working across the full stack but possess deep strength in at least one area.
• 2+ years of technical experience with Android application development, including familiarity with the Android SDK, Kotlin and/or Java, and the practical challenges of building reliable software for diverse mobile hardware.
• Prior experience with ATAK plugin development or deep familiarity with the TAK ecosystem, including CoT messaging, TAK Server integration, and the plugin architecture.
• Strong integration design skills , including the ability to define clean API contracts, design data synchronization patterns, and architect loosely coupled systems that interoperate reliably across organizational and technical boundaries.
• A highly adaptable, problem-solving mindset , with the ability to navigate ambiguity, move fast, and balance immediate operational fixes with long-term technical fidelity.
• Strong communication skills , both written and verbal. As the crucial bridge between the operational edge and our core development team, you must be able to translate complex, edge-case technical realities and user workflows into clear, actionable requirements for product engineers.

Nice to Haves

• Prior experience with CRDTs (Conflict-free Replicated Data Types) or local-first software architectures to manage complex data synchronization without a central server.
• Experience with cross-platform mobile development frameworks or strategies for maintaining parity between Android and other platform targets.
• Familiarity with tactical networking concepts , including how mobile devices operate over constrained, mesh, or MANET radio networks.
• Experience with SQLite, Realm, or other embedded databases and offline-first data persistence strategies for mobile applications.
• Direct experience operating at the tactical edge , including deploying and supporting software on end-user devices in field exercises or operational environments.
• Previous experience working directly with SOCOM, DoD, or federal customers , with an understanding of navigating secure or classified network environments.
• A background in backend or systems development (e.g., Go, Rust, Python) in addition to Android, enabling rapid prototyping of integration middleware or data translation services.

The Benefits of Building with Us

We offer competitive salaries and meaningful equity. We believe everyone on the team should have a stake in what we're building. Benefits vary by region to make sure you're covered in the ways that matter most. In the US, that includes health, dental, vision, life, and disability insurance, plus a 401(k) and flexible spending accounts.


Regardless of where you live, everyone at Ditto can utilize flexible time off. And while we work remotely, our Atlanta and San Francisco offices are open if you ever want a place to work or meet up with teammates.
