If you are an ambitious young person
I still believe joining @SpaceX is one of the best career decisions you can make
The world is pivoting from bits to atoms and there is no better training ground for atoms than SpaceX
It may feel late but it's early
Also the mission! 🚀🌕

We are serious about making energy cheaper
If you make a list of teams that have a real, honest shot at making energy 10x cheaper, Valar belongs in the top 5 from a third-party perspective. First startup to split an atom, make power, etc
Dig deeper and you’ll find that it’s #1

Excited to welcome Eric Lloyd to Valar Atomics!
Eric helped build Overwatch (great game, but it stole players from CSGO… we’ll have words about that) and has spent the last 7 years at SpaceX operationalizing the hardest parts of the business with software: the Starlink customer platform (from zero to millions of customers), the platform that engineering runs on, and the operational range software that turned Falcon launches from irregular heroics to just another Thursday.
Eric’s a legend and I’m grateful that he’s chosen to join our mission to make energy cheaper and more abundant in the universe than ever before.
Huge addition to the @valaratomics team! If you want to join our world class team and come make energy cheaper and more abundant in the universe than ever before check out our openings or DM me.
Today, I'm excited to welcome Andy Lambert to Valar Atomics as Chief Production Officer.
Andy has led an extraordinary career in manufacturing. As VP of Production at SpaceX, Andy took Falcon 9 from a fledgling single-use rocket to the world's most reliable launch vehicle and first orbital-class self-landing system, while also industrializing Falcon Heavy production and leading quality for America's primary human-rated spacecraft, Crew Dragon.
Those who know me best know my particular style of hiring executives; that is, not hiring them until I've found the best in the world. It has taken me three years to find somebody that I feel is capable of executing on our mission to turn nuclear energy from a construction industry to one based on vertically integrated mass-manufacturing and rapid deployment.
If you prick Valar Atomics in any place, you will find that we bleed scale. Every decision in our architecture has been meticulously and ruthlessly honed for building not tens of reactors, but thousands.
Nuclear reactors are simple machines, but real scaled production is very hard. I wanted to find somebody who has lived through production hell of a novel system where the safety of human life hangs in the balance.
Andy started his career working on the Harrier for the Royal Air Force, then moved into production at BMW. At SpaceX, Andy was responsible for the production of Falcon 9 and the quality of Crew Dragon, two of humanity's most challenging and safety-sensitive products. After SpaceX, Andy built complex and novel energy systems at Heliogen, then ran production at the innovative and vertically integrated hypercar company Czinger.
This mix of novel environments, unprecedented pace, deep vertical integration, and life-safety quality is exactly what Valar Atomics needs to bring humanity into the atomic age and make energy cheaper than ever before.
But more than all of that, I found Andy and his wife Carrie to be incredibly kind and genuine people who are incapable of resting on their laurels. They are hungry to help build the future. My reference checks on Andy were all consistent: he fights hard to win, but he does so in a way that brings everyone along.
If you've worked with Andy in the past, or have worked in organizations that have been fortunate enough to have him at the helm, this is your chance to see him in peak form. The mission of Valar Atomics is to make energy cheaper and more abundant in the universe than ever before. We are doing this by becoming the first company in history to build thousands of nuclear fission reactors. This will require the absolute best people in the United States working harder than they've ever worked before. But our mission is worth your efforts. Join us!
The building behind me is the beginning of @valaratomics scaling Small Modular Reactors to Gigawatt scale.
How fast we get there is a software problem as much as a nuclear one.
Hiring Sr + Principal engineers to own the operating system for Valar.
Hard problems. Total ownership.
Senior Software Engineer: job-boards.greenhouse.io/val…
Principal Software Engineer: job-boards.greenhouse.io/val…
I’m excited to share that I’ve joined @valaratomics as Head of Software.
Building alongside people tackling some of the hardest engineering problems in the world has shaped how I think about great teams, ambitious missions, and what it means to truly build.
A big reason I’m making this move is @isaiah_p_taylor and his vision for the future of nuclear energy. It aligns deeply with something I’ve believed for a long time: energy capacity is one of the fundamental constraints on humanity’s continued progress. If we want to build more, compute more, manufacture more, explore further, and raise the standard of living around the world, we need dramatically more abundant energy.
I believe nuclear is the best path to getting there.
At Valar, I’ll be building a team of exceptional software engineers, people who are builders at heart, who want ownership, move fast, and are excited to turn ambitious ideas into real systems.
If the future of energy excites you as much as it excites us, DM me. We’re building.

This is an opportunity to work with SONAT SEN himself! Legendary nuclear engineer, critical to the most impactful nuclear projects of this century.
And, you get to do that at the world’s most hardware-focused nuclear startup.
Truly a generational opportunity

OpenAI and Anthropic have opposite cultures.
OpenAI runs like a modern Bell Labs. 2-3 researchers spin up projects like GPT & Sora, then turn them into products. Maximal ambition, from each kind of model to robotics to AI device.
Anthropic is brutally focused. They believe coding is the path to AGI. Everything else is noise. No image models. No video models. No vagueposts.
It will be fascinating to see which one wins.

In a recent hotfire our BE-3U engine reached more than 211,500 lbf thrust. That makes BE-3U the highest thrust-to-weight hydrogen engine in history, at more than 90! Here is the video of that test for your enjoyment.

HOLY SHIT! They landed the booster. Huge congratulations to Blue Origin and everyone who worked their asses off to make this happen.
