Senior Networking Software Engineer

USA (Remote-Friendly) | Full-Time | Permanent | Equity Included

We’re partnering with a company pushing the boundaries of wireless communications in non-terrestrial environments. Operating at the intersection of telecommunications, aerospace, and software-defined networking, this team is pioneering solutions that aim to bring mobile connectivity to remote and underserved regions across the globe – using unconventional infrastructure to leap past the limitations of traditional networks.

About the Role

You’ll join an elite engineering team building a new category of network systems designed to interoperate with existing mobile standards (2G through 5G), while leveraging novel approaches to infrastructure placement, scalability, and energy efficiency. This is an opportunity to work on highly complex systems in a supportive, mission-driven environment where innovation is both encouraged and expected.

Key Responsibilities

• Design and implement network protocols and communications layers for novel mobile infrastructure

• Develop and maintain systems for core network signaling, control, and operations

• Create test environments and tools to validate end-to-end functionality

• Work across legacy and next-gen wireless technologies (2G/3G/4G/5G)

• Contribute to real-world deployments designed to scale globally

You’ll Succeed If You Have:

• A degree in Computer Science, Electrical Engineering, or a related technical field

• Experience developing network software for mobile or telecom systems

• Solid understanding of wireless protocols and mobile core network architecture

• Hands-on coding experience in C, C++, or Python, and confidence in Linux environments

• Familiarity with telecom standards and protocol stacks (e.g., LTE, GSM, SIP, Diameter, etc.)

Bonus Experience (Not Required):

• Network debugging tools and low-level troubleshooting (e.g., gdb, valgrind)

• Virtualization, cloud-native networking, or distributed systems

• Exposure to OSS/BSS, RAN architecture, mobility and handover procedures

• End-to-end network integration or systems engineering in regulated industries

What’s in It for You:

• Equity ownership in a rapidly scaling company

• A collaborative team culture with zero micromanagement

• True work-life balance – no weekend expectations

• Opportunity to work on technology that impacts people’s lives at global scale

• Flat structure with real autonomy, respect, and room to grow
