Base salary: $130,000–$210,000 per year, plus equity and benefits.

Company

Arena Physica builds Atlas, an AI platform that uses physics-grounded intelligence to verify, debug, and optimize hardware across its lifecycle, with applications in R&D, integration testing, production assembly, and field repair.

What you will do

• Build and maintain production-grade 2D, 2.5D, and 3D electromagnetic simulation workflows for interconnects, packages, connectors, and RF structures.
• Design and evaluate end-to-end high-speed channels across PCBs, vias, connectors, packages, and cables, producing S-parameters, RLGC models, TDR and eye implications, crosstalk, and loss or dispersion analyses.
• Simulate RF passives and structures including launches, transitions, resonators, power splitters and combiners, hybrids, couplers, matching networks, and antennas, and validate results against measurements.
• Support Altium and Cadence OrCAD PCB design integrations and workflows into Atlas.
• Correlate simulations with VNA, spectrum analyzer, and TDR measurements; define acceptance criteria and investigate root causes when models differ from measurements.
• Automate expert workflows including meshing, boundary conditions, port definitions, de-embedding, parameter sweeps, and customer-facing hardware diagnosis.

Requirements

• 3+ years of professional experience with EM simulation for SI/PI, SerDes channel engineering, RF design, or closely related work within leading industry players.
• Practical expertise with 2.5D and 3D EM solvers and workflows, including method of moments, FEM, FDTD, and industry-standard tools such as HFSS, Keysight ADS, Cadence, or Synopsis.
• Experience with Altium and Cadence OrCAD design software.
• Strong understanding of insertion and return loss, crosstalk, impedance discontinuities, via structures, launches, reference planes, dielectric and roughness loss, dispersion, and de-embedding.
• Familiarity with authoring test plans and validating simulations using VNA, spectrum analyzer, TDR, and BER measurements, including interpretation of fixtures, calibration, de-embedding, bandwidth limits, and repeatability artifacts.
• Ability to script or automate simulation pipelines and analysis in Python or a similar language, work with data pipelines, and collaborate with software engineers.
• Ability to explain complex physical behavior clearly, write structured technical reports, and align cross-functional teams around root causes and next steps.
• Ability to work in person at the New York City headquarters when not traveling and travel domestically and internationally up to 25% of the time.

Culture & Benefits

• Work at the intersection of applied research and engineering on an electromagnetic foundational model and physics-grounded hardware intelligence.
• Medical, vision, and dental insurance with 100% of monthly premiums covered for employees and dependents.
• 401(k) retirement plan.
• Unlimited paid time off.
• Daily lunch from local restaurants through Sharebite.
• Relocation support is provided.
