About RIVVOR
RIVVOR is a next-generation wireless systems company based in Silicon Valley, with engineering hubs in Montréal, Canada, and Tbilisi, Georgia. We are building ultra-high-speed wireless infrastructure using advanced mmWave and RF technologies—from Earth to orbit and beyond.
Founded by seasoned engineers from AMD and top-tier research labs, our team blends semiconductor execution, system design, and physics-driven innovation. We partner with leading universities and national labs to solve deep technical challenges in wireless communication, data movement, and infrastructure design.
If you're excited by elegant systems, complex architecture, and creating the blueprint for something truly groundbreaking, this is your moment.
About the Role
As Senior System Architect, you will define and drive the end-to-end architecture of our mmWave wireless platform. This is a pivotal leadership role where you will orchestrate efforts across RF, digital, embedded, and mechanical engineering teams to translate visionary system requirements into real-world products.
You’ll own the system diagram, define critical interfaces, and ensure seamless integration between diverse technology domains. Your fingerprints will be on every subsystem—from wave propagation to protocol logic to power and thermal layout.
What You’ll Do
Develop high-level system architecture, specifications, and interface definitions to ensure seamless integration and optimal performance.
Break down complex wireless systems into well-defined hardware and software modules.
Own signal, timing, power, and control interface design across system components
Coordinate cross-functional engineering efforts (RF, FPGA, embedded, mechanical)
Lead system integration from prototyping through pilot deployments.
Conduct technical reviews, drive risk mitigation, and maintain technical documentation.
Make foundational decisions that shape the long-term product roadmap.
What We’re Looking For
7+ years as a system architect or technical lead on complex, multidisciplinary hardware systems
Deep experience combining RF, high-speed digital, embedded software, and physical systems
Strong track record of end-to-end integration and system-level delivery
Excellent communication and technical leadership in multi-team environments
Bonus: Experience with mmWave, high-frequency systems, or wireless infrastructure
A systems thinking mindset, a sense of ownership, and a startup-ready attitude
Tools & Environments
System modeling tools • RF/digital integration • Interface spec design
MATLAB, Python, Altium, Simulink, embedded stack coordination tools
