About Rivet  

Rivet is an American company building integrated task systems — fusing hardened hardware with software, sensors, AI, and networking — for industrial workforces and defense personnel. We create capabilities that multiply the effectiveness of every individual and withstand the world’s toughest environments. 

We serve the people who build, operate, maintain, and defend our way of life. From technicians and engineers to first responders and service members, they embody the hard work, ingenuity, and meritocratic values that drive Western prosperity. Yet too often they are forced to rely on outdated tools that fail under modern pressures. Rivet exists to reset that priority. 

At Rivet, you’ll join a mission-driven team that fuses disciplines to deliver decisive outcomes where they matter most. Whether shaping our technology, strengthening our partnerships, or building our culture, every role here contributes to equipping the front lines with the modern systems they deserve.

• Teammates who want to work exclusively alongside others at the top of their field 
• Experienced, no-nonsense professionals who are execution-focused and deliver high-quality solutions above all else 

Role Description

• Building interfaces for real-time 3D and XR applications on Android and embedded linux AR devices. This role creates frontend systems using C#, C++ and frameworks like Unity or Stereokit, leveraging OpenXR for cross-platform XR support. You will ship performant, reliable user features that integrate cleanly with device services, peripherals and backend APIs.

Role Objectives

• Develop 3D/XR interfaces with Unity or StereoKit.
• Implement workflows and visualizations for device and data management.
• Write performant C# and C++ code for real-time UI and interaction.
• Integrate with OpenXR for cross-device compatibility.
• Build companion apps/services for Android-based devices in Java/Kotlin.
• Use Python for test harnesses, scripts, and build/CI tooling.
• Optimize rendering, input, latency, profile and tune on device.
• Collaborate with backend, hardware, and design for end-to-end delivery.

Role Requirements

• 3+ years building 3D/XR or real-time interactive applications.
• Proficient in C# and C++; shipped features with Unity or StereoKit.
• Experience on Android or embedded Linux devices; familiarity with AR/XR SDKs (OpenXR; ARCore a plus).
• Solid grasp of performance optimization, profiling, and memory/CPU/GPU tradeoffs.
• Java/Kotlin for Android components and peripheral integration.
• Python for scripting, automation, or test pipelines.
• Ability to partner across hardware, firmware, and cloud; track record of delivered XR or 3D features.
• Experience with Unity, Unreal Engine (or comparable 3d engines) is a plus.
