About Estes Energy: Estes develops and manufactures exceptional zero-emission power systems that unlock true scale and performance for the electrification of the commercial vehicle and equipment markets. Estes will democratize electrification by enabling powertrain solutions at better cost and performance than diesel solutions, for both high-volume established OEMs making thousands of vehicles per year, and industry newcomers making next generation electrified vehicles and equipment. Here's the ugly truth. Approximately 3.9 million barrels of diesel fuel (equal to 5.8 Terawatt-hours of energy) are consumed every day across the United States, mostly by commercial vehicles and equipment. That's 1.66 megatonnes of CO2 GHG emissions every day. That's 353 kilotonnes of NOx and 9.92 kilotonnes of SOx gases emitted, poisoning our people and planet, every day.We exist to move the needle on transitioning a century old diesel burning industry to electric. What are our principles to...

Astranis builds advanced satellites for high orbits, expanding humanity's reach into the solar system. Today Astranis satellites provide dedicated, secure networks to highly-sophisticated customers across the globe- large enterprises, sovereign governments, and the US military.With five satellites on orbit and many more set to launch soon, the company is servicing a backlog of more than $1 billion of commercial contracts. Astranis is the preferred satellite communications partner for buyers with stringent requirements for uptime, data security, network visibility, and customization.Astranis has raised over $750 million from some of the world's best investors, from Andreessen Horowitz to Blackrock and Fidelity, and employs a team of 450 engineers and entrepreneurs.

As a team, we've launched five satellites into orbit, signed ten commercial deals worth over $1 billion in revenue, raised over $750 million from top global investors, and recruited a team of over 400 world-class engineers. We all work out of our (legendary) San Francisco office, which was once used to build ships during the World Wars. Our satellites, which operate from geostationary orbit (GEO), weigh only 400 kg and utilize a proprietary software-defined radio payload. Each satellite can connect over two million people, and we're very excited for the impact we'll soon have in the Philippines, Mexico, and more! Backed by substantial funding and a passionate, collaborative team, we offer a rewarding work environment where you'll learn and make a significant impact, no matter where you are in your career. Radiation Effects Engineer As our Radiation Effects Engineer you will be responsible for characterization of radiation environments for our missions and testing analysis for...

About Atomic Semi Atomic Semi is building a small, fast semiconductor fab. It's already possible to build this with today's technology and a few simplifications. We'll build the tools ourselves so we can quickly iterate and improve. We're building a small team of exceptional, hands-on engineers to make this happen. Mechanical, electrical, hardware, computer, and process. We'll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology. Smaller is better. Faster is better. Building it ourselves is better. We believe our team and lab can build anything. We've set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we'll just invent along the way. Atomic was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years. About the...
