Job description

Point2 Technology is a San Jose semiconductor company building the RF interconnect fabric for next-generation AI data centers. Its e-Tube platform uses RF signaling over plastic waveguides to create Active RF Cables (ARCs) that break past the reach, power, and cost limits of copper and optics - backed by a recently extended $76M Series B with NVentures (NVIDIA) and now scaling its engineering team toward productization.

About the Role

Point2 Technology is hiring RFIC Design Engineers to build the high-frequency silicon behind its data-center interconnect products. You\'ll design mmWave and sub-THz RFIC blocks — TX/RX chains, mixers, LO multiplication, clock distribution, and RF front ends - and take them from schematic through layout in advanced SiGe and CMOS processes.

The work is hands-on and product-focused: modeling parasitics, coupling, EM behavior, and transmission-line effects, then integrating your blocks into Point2\'s core architecture alongside cross-functional teams. Multiple seats are open across seniority levels, with room for both seasoned mmWave designers and mid-level engineers who have real sub-THz design exposure.

Responsibilities

• Design RFIC blocks including sub-THz RX/TX amplifiers, and other high‑frequency analog circuits.
• Perform schematic‑level and layout‑level design in advanced SiGe and CMOS technologies.
• Model and analyze high‑frequency effects including parasitics, coupling, EM behavior, and transmission‑line interactions.
• Use industry‑standard tools such as Cadence, EMX, HFSS and Calibre for design, simulation, and verification.
• Collaborate with cross‑functional engineering teams to integrate RFIC blocks into system‑level architectures.
• Contribute to design reviews, architecture discussions, and high‑frequency performance optimization.

Qualifications

• Ph.D. in Electrical Engineering with 3+ years of relevant industry experience, or M.S. with 5+ years of relevant industry experience.
• Hands‑on experience designing RFIC blocks at mmWave or sub‑THz frequencies.
• Experience designing, testing or working with RF systems at frequencies of 20 GHz or higher.
• Strong understanding of high‑frequency IC fundamentals including EM effects, layout impacts, and transmission‑line behavior.
• Proficiency with Cadence, EMX, and Calibre; Unix/SKILL experience a plus.
• Strong teamwork, communication, and multitasking skills in a fast‑moving environment.

Required Skills

• Hands-on RFIC block design at mmWave or sub-THz frequencies (20 GHz and above)
• Experience across key blocks: TX/RX chains, mixers, LO multiplication, clock distribution, RF front end
• Strong grasp of high-frequency IC fundamentals — EM effects, parasitics, layout impact, transmission-line behavior
• Proficiency with Cadence, EMX, and Calibre
• Demonstrated productization experience (silicon that shipped, not research alone)

Preferred Skills

• 5G mmWave background — strong fit for the senior seats
• HFSS and similar EM simulation tools; Unix/SKILL scripting
• Strong teamwork, communication, and multitasking in a fast-moving environment
