JOB OVERVIEW
The Senior DSP Engineer for Space-Based Mesh Networks will design, implement and optimize advanced signal-processing and communication algorithms for a distributed constellation of satellites. Working closely with senior technical leaders, you will contribute to the development of resilient, high-performance networking technologies for LEO missions.
This role blends deep DSP expertise with hands‑on FPGA development, space‑system constraints, and cross‑link communication challenges unique to orbital environments.
RESPONSIBILITIES
- Design and implement DSP algorithms for satellite‑to‑satellite and satellite‑to‑ground communication, including modulation/demodulation, channel estimation, equalization, and error‑correction coding
- Develop real‑time signal‑processing pipelines optimized for radiation‑tolerant embedded systems and FPGA‑based accelerators
- Contribute to the design and implementation of cross-link communication protocols
- Model and simulate RF/optical link performance, including Doppler effects, multipath, interference, and orbital dynamics
- Implement DSP modules on FPGAs, including pipelined, parallel, and high‑throughput architectures for low‑latency inter‑satellite links
- Write and maintain HDL code (Verilog, VHDL, SystemVerilog, or Chisel) for custom signal‑processing blocks, PHY‑layer modules, and hardware accelerators
- Collaborate with RF, antenna, networking, and spacecraft systems teams to ensure seamless integration across hardware, firmware, software and network operations
- Perform system‑level analysis including link budgets, timing closure, resource utilization, and power constraints for space‑qualified hardware
- Participate in technical reviews and contribute to engineering decisions
- Share knowledge and support junior engineers when appropriate
- Contribute to architecture discussions and technology evolution
- Document designs and performance results for internal engineering teams, mission partners, and regulatory bodies
QUALIFICATIONS AND STUDIES
- Master’s or PhD in Electrical Engineering, Computer Engineering, Aerospace Engineering, or related field.
- 5+ years of experience
- Strong background in digital communications theory, including modulation, coding, synchronization, channel estimation, and PHY‑layer design.
REQUIREMENTS
- Tech skills
- Hands‑on experience with C/C++ or similar language for embedded DSP implementation
- Proficiency in MATLAB, Python (NumPy/SciPy), or similar modeling tools for simulation and prototyping.
- Extensive experience with FPGA development, including synthesis, timing closure, verification, and hardware bring‑up
- Proficiency with HDLs: Verilog, VHDL, SystemVerilog, or Chisel
- Experience with FPGA development; experience with space-qualified or radiation-tolerant platforms is considered a plus.
- Familiarity with RF communication systems; experience with beamforming or optical communications is a plus.
- Ability to optimize algorithms for real‑time constraints, limited power budgets, and harsh space environment
- This role requires relocation to our Italian headquarters and regular on‑site presence
- Soft skills
- Excellent communication skills and ability to lead technical discussions.
- Ability to work effectively in cross-functional engineering teams.
- Rigorous, detail-oriented approach, with a preference for measured/verified data over assumptions, and transparency when prior estimates need correction.
- Comfortable working in a fast-moving, still-maturing product environment, iterating on both architecture and hands-on implementation.
- Fluent English (written and spoken) required, given interaction with external international partners.
WHAT WE OFFER
- A flat and collaborative organizational structure
- A fast‑paced and professional environment within a rapidly growing space scale‑up
- Challenging projects with real impact on the global space ecosystem
- An international and diverse workplace
- Comprehensive benefits package, including a welfare platform, meal vouchers, a hybrid work policy supporting work-life balance, and training opportunities
COMPENSATION & TRANSPARENCY:
- Reports to: Head of Engineering
- Career level: P4 – Senior Professional
- Job location: Lomazzo (Como), Italy | Hybrid work model
- Salary range: 55–70k, depending on experience and skills.
- Variable compensation: 10% of annual gross salary
- Benefits: Competitive benefits package, including a welfare platform and meal vouchers in Italy, with equivalent local benefits provided where applicable
- Expected start date: 1.10.2026
