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: 1.9.2026
