Senior Software Engineer- Networking Security

Position Overview

• Location Type: Remote
• Job Type: Full-time
• Salary: Competitive salaries

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. military 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.

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, and edge platforms for mesh systems. Work remotely, set your own schedule, and solve complex, meaningful problems.

Requirements

• 2–5 years of professional software engineering experience.
• Solid background in networking, backend or systems-level development.
• Proficiency in at least one programming language such as Rust, C++, Go or similar.
• Experience designing and consuming APIs for higher level abstraction.
• Understanding of networking as well as application layer routing and communication protocols.
• Comfort working with distributed systems or edge-deployed services.
• Ability to reason about concurrency, performance, and fault-tolerant architectures.
• Strong collaboration skills as you'll work cross-team particularly closely with product and relevant team engineers spread across the globe.

Nice to Haves

• Familiarity with networking concepts like routing protocols, transport layers, and peer-to-peer communication.
• Some experience with security standards, performance and throughput optimizations at system level.
• Familiarity with Conflict-free Replicated Data Types (CRDTs)
• Experience implementing or working with communication protocols.
• Some experience with or high level of interest in Rust.
• Strong written communication skills (as we operate asynchronously and value well-structured design docs).

Responsibilities

• Lead the development of core edge services that power Ditto's mesh-based systems.
• Build software that manages peer discovery, multi-channel communication, and routing across unreliable or dynamic networks.
• Design clean, efficient APIs that allow higher-level applications to interact with the mesh layer.
• Lead the development and maintenance of Ditto’s networking stack by designing and implementing secure authentication flows, encryption protocols, and access controls.
• Contribute to protocol design, transport abstraction, and system-level performance improvements.
• Collaborate with security and infrastructure teams to continuously audit, harden, and optimize network security and authorization (RBAC) mechanisms.
• Collaborate with other engineers and product teams to deliver end-to-end features that reach real-world users.
