Software Engineer – Backend

You will work on backend systems for AuraNet, Dominion Dynamics' mesh networking platform for autonomous assets in contested environments. The role involves designing high-performance services, developing pub/sub networking with Zenoh, building APIs, integrating with flight stacks and simulation environments, and managing secure asset workflows. You will also contribute to testing, CI/CD, code reviews, and platform architecture.

Responsibilities

• Design and build high-performance backend services for data ingestion, processing, and real-time distribution.
• Develop and optimize pub/sub networking capabilities using Zenoh to support low-latency, end-to-end encrypted mesh communications.
• Build and maintain GraphQL and REST APIs that power operator interfaces, internal tooling, and external integrations.
• Create integrations with flight stacks and simulation environments — MAVLink, ArduPilot, Unreal Engine, and Gazebo.
• Develop secure asset management workflows using certificate-based authentication and PKI infrastructure.
• Build automated testing frameworks and contributes to CI/CD pipelines for reliability and rapid iteration.
• Review code, maintains engineering standards, and contributes to overall platform architecture.
• Work across disciplines to integrate software into deployed autonomous systems.

Requirements

• Strong understanding of networking fundamentals — TCP/IP, UDP, and publish/subscribe architectures.
• Experience with security concepts — end-to-end encryption, PKI, authentication, and authorization.
• Production experience in Go, Python, Java, C++, or a comparable backend language.
• Experience building and shipping distributed systems in production environments.
• Strong software engineering fundamentals; writes clean, maintainable code.
• Eligibility for Canadian security clearance preferred; Canadian citizenship an asset.

Nice to have

• Experience with mesh networking or distributed communication systems.
• Familiarity with Zenoh or similar messaging technologies.
• Experience integrating with robotics, UAV, or autonomous platforms.
• Exposure to simulation environments such as Unreal Engine or Gazebo.
• Experience with Linux-based systems and containerized deployments.

Benefits

• Competitive base salary and company equity
• Comprehensive health benefits
• Additional equity granted based on impact
