RAETH Al is hiring Full Stack Engineer Intern (with
PPO opportunity)
Location: Remote Pay: up to 1.5L/month
RAETH builds Al training infrastructure for frontier labs (evals, RL envs, expert data) focused on quant trading, betting and business use cases.
You'll be building the interfaces and tooling that turn
our infrastructure into something humans can
actually use: dashboards for eval runs, internal tools for data labeling, customer-facing platforms for lab clients, and whatever else needs to exist by Friday.
Requirements:
- Good design skills
- Comfortable with databases, APIs, auth, deployment.
. You ship fast and iterate. You don't ask for a Figma before writing code.
- You can code in Python without Al holding your
hand
Nice to have:
- Worked on developer tools, internal platforms, or
ML-adjacent products
- Background in trading, finance, or business
- A portfolio of things you've actually shipped, not
- just repos with three commits
Comment and I will drop contact details in your DM 👇🏻

Had a Jane Street phone interview in 2016. "Price a 6-month forward on carrots."
There's no carrot futures market, so I build one from scratch: seasonal harvest cycles, USDA demand elasticity, cold storage decay rates.
One trader stops me. "Your storage cost function– you're modeling the carrot as dead inventory. Like grain in a silo." He asks me the metabolic respiration rate of a post-harvest carrot at 2°C. I estimate.
"Your forward is overpriced by exactly that shrinkage. The underlying is consuming its own sugars. It's alive." Good correction. I adjust the model. I think I've recovered.
Rejection email comes the next morning. Subject: "Ethical Review." My framework, they write, "relied on the severance of the root organism from its growth medium." The question about respiration was a test. The carrot was still alive and I'd built an entire derivatives structure on top of its death without questioning whether harvest was an acceptable act.
I pull up the recruiter's original email. It doesn't say Jane Street. It says Jain Street– a non-violent quantitative commodities fund.
The carrot was never supposed to be priced. It was supposed to be refused. I later learn the only candidate who passed that round was a former monk from Gujarat who sat in silence for eleven minutes and said, "I cannot put a price on life." He's now a partner.

Jane Street made ~$40B in 2025 with 3,500 employees, a ~2x from the year before. At ~65-70% profit margin, that's $8M profit / employee, the highest for a 1000+ ppl company. High-frequency trading continues to be the most efficient money making engine. I want to share an old story about my Jane Street interview in 2014. Jane Street was known for hiring a lot of math, physics and CS olympiad winners from top universities and putting them through many rounds - including, for trading roles, a gauntlet of mental math. It was my 6th interview and my final round and I recall being asked "What is the next day after today in DD/MM/YYYY where all the digits are unique?" They'd toy with you and say "You can use a pencil and paper, if you want" but you knew that was an instant no. Painstakingly and as quickly as I could, I came to an answer. "How confident are you that this is correct on a 0-1 probability scale?" the interviewer said. "0.95", I blurted out, not fully knowing how to answer that. "Are you sure?" After thinking harder for a few more seconds, I realized I could've flipped the digits around to get a closer date. I gave the interviewer my answer. It was correct. "0.95 huh?" he chuckled. That's when I knew I failed. Note: fwiw, other companies that come close in efficiency are - Tether ($90M+ profit/emp) - Hyperliquid ($80M+ profit/emp) and on revenue: - Valve ($50M/emp) - OnlyFans ($37M/emp) - Craigslist ($14M/emp) - Anthropic ($12M/emp, run rate) - OpenAI ($8M/emp, run rate) For comparison, Nvidia is very efficient at scale and is $4.4M/emp.

Make sure you read code while developing with AI, it can do pretty amazing as well as damaging stuff and you won't even understand when it crashed your system
