The posting

About Us:

We are a dynamic and rapidly growing company developing next-generation telecommunications technologies for global markets. Our mission is to shape the future of wireless by delivering cutting-edge 5G and 5G mmWave solutions. We're looking for a Telecom Systems Software Engineer to join our RAN team and play a key role in developing and maintaining the L1/L2/L3 protocol stack and enabling multi-platform support (x86 and ARM).

Your Role:

As a Telecom Systems Software Engineer, you will be responsible for maintaining and enhancing the software stack of our 5G Radio Access Network (RAN) solutions. This includes implementing new features across L1/L2/L3, optimizing the system for new architectures (ARM), and integrating licensing mechanisms. You’ll work with a multi-disciplinary team on real-time telecom solutions in a fast-paced, collaborative environment.

Responsibilities

  • Design, develop, and maintain 5G RAN software stack (L1/L2/L3 layers).
  • Port and optimize the codebase for ARM architecture (currently runs on x86).
  • Integrate software licensing mechanisms into the existing RAN stack.
  • Work closely with hardware teams to ensure seamless integration between RU, DU, CU, and Core components.
  • Support time synchronization technologies (PTP/SyncE) for real-time radio operation.
  • Troubleshoot and resolve issues in live and test environments.
  • Create and maintain technical documentation, including interface specs and system configs.
  • Collaborate with QA to create automated test scenarios (Python, Bash).
  • Provide guidance on software and hardware requirements for RAN deployment.
  • Bachelor’s or Master’s degree in Telecommunications, Electrical Engineering, Computer Science, or related field.
  • 2+ years of experience in embedded or telecom systems software development.
  • Solid knowledge of 4G/5G RAN architecture and protocol layers (MAC, RLC, PDCP, RRC).
  • Strong Linux development skills.
  • Proficiency in C/C++ and Python.
  • Familiarity with Git and CI/CD tools.
  • Understanding of system performance tuning and resource management.
  • Experience with ARM and x86-based platforms.
  • Good command of English (spoken and written)

Good to have

  • Experience with O-RAN interfaces and specifications.
  • Knowledge of time synchronization protocols (PTP, SyncE).
  • Familiarity with FPGA or SDR-based systems (Verilog/VHDL a plus).
  • Experience with software licensing systems or commercial protection frameworks.

Job benefits

  • Salary: 10,000 – 20,000 PLN gross (contract of employment or B2B/casual contract).
  • Flexible working model: on-site, remote, or hybrid.
  • Private healthcare & sports package.
  • Opportunity to work on cutting-edge telecom tech from day one.
  • Integration events and a collaborative, startup-like culture.
  • A real impact — you’ll help shape the backbone of next-gen wireless networks.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
