Senior Software Engineer, Platform Integration

Senior Software Engineer, Platform Integration

About Forterra At Forterra, we are unleashing autonomy at scale to transform the battlefield. Our mission is to build the foundational platforms that enable an intelligent ecosystem to coordinate, adapt, and execute with speed and precision even in the uncertainty and disruption of modern conflict. In an era marked by rapid technological change and evolving threats, we design for flexibility, survivability, and operational dominance.

Forterra delivers weapons, sensors, and battlefield effects through integrated autonomous networks reaching operational areas faster, safer, and without placing human lives  systems operate with distributed control, dynamic routing, and real-time responsiveness, enabling sustained advantage across complex mission environments.

Fabric is Forterra's distributed systems platform for registering, discovering, and replicating mission-critical data across dynamic mesh network topologies. Fabric enables interoperability between autonomous vehicles, operators, services, and partner systems across unreliable, bandwidth-constrained networks.

Fabric is foundational infrastructure used by multiple internal teams and external integrators. It connects autonomy systems, command-and-control applications, operator interfaces, vehicles, and partner technologies into a common operational ecosystem.

We are seeking a Senior Software Engineer to focus on Fabric integrations and developer-facing APIs. You will help make Fabric easier to adopt across Forterra's products and by external partners, building the interfaces, adapters, SDKs, tools, and documentation that connect Fabric to real-world systems.

This role is ideal for a generalist engineer who enjoys working across system boundaries. You will partner directly with teams building autonomy, command and control, networking, web applications, and vehicle software to understand their needs and deliver reliable integrations. You should be comfortable moving between API design, backend services, data modeling, distributed systems, testing, deployment, and technical documentation.

This is a hands-on role with significant ownership and cross-team influence. You will help shape how developers and integrators interact with Fabric while contributing to the evolution of the platform itself.

• Design and build APIs, SDKs, adapters, and integration tools that enable applications and partner systems to use Fabric.
• Define clear interfaces for registering, discovering, querying, subscribing to, and replicating mission-critical data.
• Build integrations between Fabric and systems such as autonomy services, command-and-control applications, operator interfaces, vehicle platforms, web applications, and external partner software.
• Develop and maintain APIs using technologies such as gRPC, REST, Protocol Buffers, or comparable interface technologies.
• Establish patterns for schema evolution, versioning, compatibility, serialization, authentication, authorization, and error handling.
• Translate real-world integration requirements into practical technical designs and production-ready implementations.
• Work directly with internal teams and external integrators to troubleshoot issues, close capability gaps, and improve the developer experience.
• Build testable, observable, and maintainable services that operate across distributed and intermittently connected environments.
• Create integration examples, reference implementations, automated test harnesses, and developer documentation.
• Improve tooling and workflows for local development, simulation, integration testing, deployment, and field support.
• Collaborate with platform, autonomy, networking, Terra Link, ATAK, web,…
