Senior Staff Software Engineer (NR-NTN)

Senior Staff Software Engineer (NR-NTN)

Skylo Technologies

Espoo, Finland

As a staff software engineer, you will be the technical visionary driving the development of Non-Terrestrial Network (NTN) capabilities within our gNodeB software stack. This role sits at the intersection of traditional cellular protocol engineering and the evolving domain of satellite communications. You will oversee the entire software lifecycle - from 3GPP feature analysis to high-level architectural design - ensuring our RAN systems meet the unique timing and mobility challenges of satellite-integrated 5G.

How You Will Contribute

• Architectural Leadership: Lead the end-to-end design, development, and maintenance of 5G NR L2/L3 protocol stacks and MAC-Schedulers specifically optimized for NTN (LEO/GEO) environments.
• Requirement Analysis: Translate 3GPP Release 17/18+ NTN specifications into actionable software requirements and technical roadmaps.
• Design & Development: Author High-Level Designs (HLD) and Low-Level Designs (LLD) for gNodeB components, focusing on compensation for large propagation delays and high Doppler shifts.
• Feature Prioritization: Analyze and prioritize 3GPP features (e.g., HARQ disabling, timing advance enhancements, and cell discontinuous coverage) for integration into the RAN subsystem.
• Mentorship & Quality: Provide technical guidance to development teams, perform code reviews, and ensure the architectural integrity of the product during maintenance and delivery phases.

What We Look For

• Experience: In LTE/5G NR protocol software development, with at least 3 years in an Architect or Lead Developer role.
• Satellite Domain: Proven track record of adapting terrestrial RAN software for satellite payloads or transparent/regenerative architectures.
• Testing: Experience with UE simulators and channel emulators configured for high-latency satellite profiles.
• Education: Bachelor’s or Master’s degree in Computer Science, Telecommunications, or Electronic Engineering.
