Roguebeam is a startup developing advanced phased array systems for communications and radar applications. We design and manufacture complete systems in-house-RF, antenna, digital, and DSP-giving our engineers end-to-end ownership of the technology and a direct line of sight from algorithm to deployed system.

We're early, we're growing fast, and the people who join us now will shape both the technology and the company.

We're looking for a Principal DSP Engineer to set the technical direction for the digital beamforming and radar signal processing at the heart of our phased array systems. As a foundational technical leader, you'll help set the direction of both our product and signal-processing roadmap, define the algorithmic architectures that underpin our systems, and establish the modeling and verification culture the team scales on.

You'll work across the full signal path-from algorithm concept through real-time implementation-partnering closely with RFIC, antenna, and digital hardware teams. As a principal-level individual contributor, you'll be the person others turn to on the hardest signal-processing problems, and the decisions you make will ripple through every product we build.

• Develop digital beamforming algorithms for phased array communications and radar systems
• Design and prototype radar signal processing chains - detection, Doppler, pulse compression, clutter mitigation, and tracking
• Take algorithms from concept and modeling through real-time implementation on FPGA/SoC platforms
• Analyze performance against system requirements (SNR, dynamic range, angular accuracy, false-alarm and detection rates)
• Collaborate with RFIC, antenna, and digital hardware teams to co-optimize the array and the processing that drives it
• Support lab bring-up, data collection, and over-the-air validation of fabricated systems
• Define algorithmic architectures and lead the most complex and ambiguous processing challenges
• Set technical direction across the DSP roadmap and influence system-level trade-offs spanning RF, antenna, and digital
• Establish modeling, coding, and verification standards; mentor and elevate the broader team

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field
• 10+ years of relevant experience in DSP, radar signal processing, or digital beamforming, with a track record of leading complex algorithms from concept to deployed system
• Expert command of signal processing fundamentals: detection and estimation, adaptive filtering, and array processing
• Deep proficiency in algorithm modeling (e.g., MATLAB or Python) and a strong track record of real-time implementation on FPGA/SoC platforms

• MSc or PhD with a focus on signal processing, radar, or communications
• Experience with digital beamforming for phased arrays
• Familiarity with adaptive beamforming, STAP, MIMO radar, or space-time processing
• Experience implementing DSP on FPGAs (Verilog/VHDL/HLS) or DSP-capable SoCs
• Background bridging algorithm development and real-time embedded implementation
• Experience with over-the-air test and measured-data validation

This is a rare ground-floor opportunity. Joining a startup at this stage means your work has a direct, visible effect on whether the company succeeds—and a corresponding upside as we grow. Because we build the entire system in-house, you'll see your algorithms running on real phased arrays and deployed in working systems, not handed off and forgotten. You'll have real ownership and a seat at the table on technical direction.
