Staff Engineer, Optics & RF

About Cowboy Space Corp:

Mission
Cowboy Space Corporation is solving the global energy crisis by building the infrastructure for abundant, resilient space-based solar energy. We are tackling one of humanity’s most complex engineering challenges with a world-class team dedicated to delivering a revolutionary power platform. Cowboy Space Corporation is transforming how civilization powers, computes and connects - from orbit to Earth.

Background
Cowboy Space Corporation is building the infrastructure to power and connect the orbital economy. Our modular, scalable satellites collect sunlight in Low Earth Orbit to enable multiple integrated applications: transmitting energy via infrared lasers (space-to-earth and space-to-space), powering on-orbit high-performance computing clusters (GPU/TPU), and providing secure, high bandwidth optical data transport.

Current energy and data systems rely on complex logistics and outdated infrastructure. Cowboy Space Corporation overcomes these challenges by enabling direct, on-demand, secure, and scalable energy distribution and data processing from space. This will revolutionize how we operate in orbit and on Earth, supporting the rapidly expanding space industrial base, ISAM (In-Space Servicing, Assembly, and Manufacturing) operations, remote regions, and military bases.

Baiju Bhatt founded Cowboy Space Corporation in 2024. Inspired by his father’s work with NASA Langley Research Center, Baiju earned his B.S. in Physics and M.S. in Mathematics at Stanford before co-founding Robinhood, now a public company that has helped over 20 million Americans access the financial system. Cowboy Space Corporation has raised ~$365 million from Index Ventures, Interlagos, Construct Ventures, Breakthrough Energy Ventures, Andreessen Horowitz, NEA, and others.

This is an ambitious mission that demands extraordinary talent. Cowboy Space Corporation ’s team has worked at places like SpaceX, Blue Origin, Stoke Space, Astranis and NASA, and is based in San Carlos, CA. If you're ready to solve complex technical challenges and help build the most important energy company in the world, we want to hear from you.

• Stay current with advances in optical communication technology, RF driver ICs, and opto-electronic component development

Basic Qualifications:

• Bachelor's or Master's degree in Electrical Engineering, RF Engineering, Photonics, or related field

• 5+ years of professional experience designing RF circuitry for high-speed communication systems

• Hands-on experience designing RF circuits to drive optical communication links (laser drivers, TIAs, modulator drivers)

• Direct experience with free-space/open-space laser communication systems

• Proven experience working with high-speed RF communication links in the 1 Gbps to 50 Gbps range

• Strong PCB design and layout experience for RF circuitry, including familiarity with specialized RF PCB stack-ups (e.g., mixed dielectric, controlled impedance, RF-grade laminates)

• Solid understanding of RF transmission line theory, impedance matching, and high-speed signal integrity principles

• Proficiency with RF simulation and design tools (ADS, HFSS, or equivalent) and PCB design tools (Altium, Cadence Allegro)

• Experience with lab test and measurement equipment for high-speed RF characterization (network analyzers, BERTs, oscilloscopes, eye-diagram analysis)

• Strong analytical and problem-solving skills with the ability to debug complex RF/optical system issues

• Effective communicator able to collaborate cross-functionally with optics, mechanical, and systems teams

Preferred Qualifications:

• Knowledge and hands-on experience with opto-silicon (silicon photonics) design and integration

• Experience with space-qualified or radiation-tolerant RF/optical hardware design

• Familiarity with laser diode driver ICs, transimpedance amplifiers (TIAs), and high-speed modulator technologies

• Background in coherent or direct-detection optical communication link design

• Experience with pointing, acquisition, and tracking (PAT) subsystems for free-space optical terminals

• Understanding of link budget analysis and optical power/noise trade-offs for free-space channels

• Familiarity with fiber-optic component integration (photodiodes, laser diodes, optical amplifiers)

• Experience with EMI/EMC mitigation techniques for high-speed RF/optical systems

• Publications or patents related to RF/optical communication system design

Technical Skills & Tools:

• RF/EM simulation: Keysight ADS, Ansys HFSS, or equivalent

• PCB design: Altium Designer, Cadence Allegro, or equivalent

• Signal integrity analysis: S-parameters, TDR, eye-diagram/jitter analysis

• Test & measurement: Vector network analyzers, BERTs, high-speed oscilloscopes, optical power meters

• Optical component familiarity: laser diodes, photodetectors, TIAs, modulators

Compensation and Benefits:

The salary range for this position is $219,000 - $276,000 annually. The actual base salary offered will depend on factors such as job-related skills, experience, qualifications, and internal equity.
