[Hiring] Senior Software Engineer @Ditto

Role Description

Ready to shape the future of mesh networking? Join a team at the forefront of next-generation network technology at Ditto. We're expanding our core network stack and building high-performance solutions in next-generation networking, including:

• Routing protocols
• End-to-end connectivity
• Transport mechanisms
• Edge platforms for mesh systems

Work remotely, set your own schedule, and solve complex, meaningful problems. As a Software Engineer – Networking, you will:

• Design, implement, and own core components of Ditto’s networking and transport stack, spanning overlay networking and underlying physical transports and protocols.
• Drive the re-architecture of the networking stack toward a more modular, scalable, and high-performance design.
• Debug and systematically improve real-world connectivity issues.
• Build and optimize transport mechanisms with explicit attention to flow control, backpressure, and failure recovery.
• Identify and eliminate performance bottlenecks across latency, memory footprint, CPU utilization, and tail behavior.
• Design protocol state machines, wire formats, and transport abstractions.
• Establish meaningful observability through targeted logging, metrics, and diagnostics.

This role is ideal for engineers passionate about networking, distributed systems, and building low-level infrastructure that operates at scale and in constrained environments.

Qualifications

• 5+ years of professional experience building systems software, with at least 3 years focused on networking, transport protocols, or routing.
• Strong proficiency in Rust or C++, including ownership and borrowing semantics, async runtimes, concurrency primitives, and profiling/optimization techniques.
• An understanding of key mesh networking topics such as TCP, UDP, and QUIC semantics and tradeoffs.
• Exposure to or experience working with networked services and protocols.
• Experience designing modular APIs and abstractions that scale across multiple implementations.
• Clear written and verbal communication skills in a distributed, asynchronous team environment.
• A passion to learn new networking technologies, APIs, and approaches.

Requirements

• Experience with mesh networking protocols, routing algorithms, or gossip protocols.
• Understanding of mobile platform constraints including background execution models and battery optimization.
• Experience with Apple Core Bluetooth or Android WiFi Aware APIs.
• Experience with Linux networking, sockets, async I/O, or low-level systems programming.
• Willingness to travel once per quarter for in-person team gatherings.

Benefits

• Competitive salaries and meaningful equity.
• Health, dental, vision, life, and disability insurance in the US.
• 401(k) and flexible spending accounts.
• Flexible time off for all employees.
• Access to the Atlanta office for remote workers.
