Copy of C++ Software Engineer, Distributed Systems

We are seeking a Senior/Staff Software Engineer to help design and build Fabric, Forterra's core distributed systems platform. This role is ideal for a senior engineer who thrives in ambiguous problem spaces, enjoys building foundational infrastructure, and has deep experience with modern C++ and distributed systems.

As a Staff Engineer, you will operate at a system-wide level: shaping architecture, setting technical direction, and delivering high-impact features. You will work closely with platform, autonomy, networking, and application teams to ensure Fabric scales across products, teams, and deployment environments.

This is a hands-on technical role with significant architectural ownership and cross-team influence.

What you'll do

• Lead the design and implementation of core Fabric services and libraries in modern C++
• Architect distributed systems that operate reliably over low-bandwidth, high-latency, and unreliable networks
• Design APIs and abstractions that enable teams to register, serialize, replicate, and query arbitrary data types
• Define and evolve patterns for discovery, addressing, routing, and replication across fixed and dynamic topologies
• Build and maintain high-performance messaging, transport, and synchronization layers
• Drive decisions around consistency models, reliability guarantees, and failure handling
• Collaborate with partner teams (autonomy, TerraLink, ATAK, web, and external integrators) to ensure Fabric meets real-world requirements
• Establish best practices for correctness, performance, observability, and maintainability
• Contribute to long-term technical strategy, roadmap planning, and architectural reviews
• Document designs clearly for both engineering and integration audiences
• What Sets This Role Apart

• You'll lead projects and own subsystems
• You'll build software that operates in real-world, high-consequence environments
• You'll influence architecture, standards, and long-term technical direction and develop a core piece of Forterra infrastructure.

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience
• 8+ years of professional software engineering experience
• Expert-level proficiency in modern C++ (C++17 or later)
• Experience with publish/subscribe or message-oriented middlewares (e.g., gRPC, DDS, ZeroMQ, MQTT, custom transports)
• Strong testing fundamentals and experience developing automated tests in C++ using GoogleTest, Boost.Test, or similar frameworks (unit, integration, regression).
• Familiar with best practices such as test case design, edge-case coverage, mocking/stubbing, and maintaining reliable CI-friendly test suites.
• Solid understanding of distributed systems fundamentals, including:

• Replication and consistency models
• Leader election and coordination
• Failure detection and recovery
• Concurrency and synchronization

• Experience building or operating production distributed systems
• Deep familiarity with Linux-based development and deployment environments
• Proven ability to lead technical projects from concept through production
• Strong written and verbal communication skills, with the ability to explain complex systems clearly, * Networking expertise, including unicast/multicast, routing, and constrained or unreliable links
• Experience building systems for edge environments, robotics, or embedded platforms
• Familiarity with real-time or near-real-time systems
• Familiarity with consensus protocols (e.g., Raft, Paxos, or variants)
• Experience with CMake, Conan, Bazel, or similar build systems
• Exposure to observability tools (logging, metrics, tracing) in distributed systems
• Background in defense, automotive, robotics, or safety-critical software

The salary range for this role is an estimate and is based on a wide variety of compensation factors. The salary offered to candidates will vary based on a variety of factors including (but not limited to) relevant work experience, education, specialized training, critical expertise, training, and more.
