Software Engineer, Mobile Transports

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.

Role Description

Help us push the boundaries of how devices connect and share data. As a Software Engineer, Mobile Transports at Ditto, you'll be part of the team responsible for advancing the core transport technologies that power Ditto's decentralized networking stack. Your work will directly shape the reliability, performance, and scalability of Ditto's mobile connectivity infrastructure.

This role is ideal for engineers who are excited about networking at the edge (where radios, protocols, and code all meet) and who want to build systems that make distributed networking seamless across a variety of environments.

You'll collaborate with cross-functional teams to design, implement, and validate transport-layer technologies that leverage mobile networking features such as AWDL, Wi-Fi Aware, LAN, and Bluetooth Low Energy (BLE). You'll also help develop tools, tests, and frameworks that ensure Ditto's transports perform reliably across platforms and devices.

What You'll Be Up To…

• Design, implement, and optimize Ditto's mobile transport infrastructure across iOS and Android platforms.
• Develop internal frameworks, testing harnesses, and tools to validate performance and reliability across diverse environments.
• Work closely with the core transports and platform teams to integrate new transport capabilities into Ditto's stack.
• Analyze and improve networking performance with focus on latency, throughput, and connection stability.
• Build scalable systems to measure and monitor transport behaviors in real-world conditions.
• Collaborate with product and SDK teams to ensure new transport features are developer-friendly and production-ready.
• Participate in code reviews, testing, and design discussions that shape the future of Ditto's connectivity layer.

What Helps You Thrive…

• Up to 2 years of professional software development experience in mobile.
• Solid understanding of networking fundamentals (TCP/IP, UDP, sockets, routing, and general LAN networking concepts).
• Exposure to or interest in mobile connectivity technologies such as AWDL, Wi-Fi Aware, LAN, and Bluetooth Low Energy (BLE).
• Experience programming in at least one of the following: Python, Rust, Kotlin, Swift, Java, or C++.
• Ability to design, debug, and optimize performance-sensitive code on mobile devices.
• Familiarity with debugging tools and logs for distributed or asynchronous systems.
• Strong communication skills, especially in written form—our engineering process relies heavily on written collaboration and documentation.
• Open-minded and proactive in exploring how AI can transform the way we work and deliver impact.

Great-to-Haves…

• Experience with low-level networking APIs or building transport protocols.
• Understanding of cross-platform SDK development.
• Exposure to Rust, Go, or C for systems-level work.
• Background in wireless performance testing or network diagnostics tooling.
• Contributions to open-source networking projects or research related to peer-to-peer or mesh networking.
• Interest in or experience with network simulation and testing frameworks.

Base Salary Range $128,000 - $230,000 USD
