Pros

I’ve worked at several companies tackling genuinely difficult technical problems, but this is one of the few trying to define an entirely new category. The ambition isn’t just building better tools — it’s fundamentally changing how physical products are designed, built, and operated by combining simulation, real-world data, and machine learning in ways that haven’t really existed at scale before. In short - it's unusually challenging but a hell of a lot more rewarding than building a chatbot. The calibre of people is extremely high, and there’s a strong bias toward ownership and autonomy. If you enjoy being trusted to figure things out rather than being handed rigid playbooks, you’ll probably thrive here. The company is growing exceptionally quickly, which creates opportunities for you to shape how things are done and ultimately wear many different hats. Leadership is ambitious about the long-term vision - which comes with inherent risk - but massive upside.

Cons

Like most high-growth startups, it can be intense and frequently chaotic. Priorities evolve quickly as the company scales and as we learn from customers, which can feel disorienting if you prefer stability or clearly defined roles. Communication and visibility can vary between teams, and the company is still figuring out how to consistently scale recognition, alignment, and management capability alongside headcount growth. The way we support our customers is evolving in realtime. That’s exciting, but it means not everything is fully formed yet, and you have to be comfortable operating with some ambiguity. This is not a low-pressure or fully polished environment, but that’s largely because the company is trying to build something genuinely new. If you want predictability and defined lanes, it may not be the right fit. If you want to work on complex, high-impact engineering problems with smart, motivated people and help shape a rapidly evolving company, it’s an incredibly rewarding place to be.

Pros

Team: Amazingly talent dense organisation. I ask people about their background and they're like oh I grew up in a village in Portugal then got a scholarship to MIT then did my PhD at CalTech and joined JPL and now I'm a PhysicsX... wow. Purpose: PhysicsX is using AI to help address some of the biggest industrial challenges in the world around energy, decarbonisation, aerospace and defence and so on - feels good to be doing something meaningful with tech and AI not creating slop videos or whatever. Travel: great opportunities to travel for customer work and other occasions (we all got together in London before Christmas) Comp: solid salaries, apparently more of a focus on bonuses going forward which is great, and if it works out the equity should be meaningful - fingers crossed.

Cons

Scaling: Like any company that's growing this fast it's surfing the line of chaos, and kind of back filling on things like processes. New leadership coming in like Chief Operating Officer, Chief People Officer and so on hopefully help us catch up with ourselves. But not too much bureaucracy please! Work life balance: it's intense. You learn a tonne, you get things done fast, it's great energy - but it's NOT a nine to five for sure.
