A site that already works — restructured so institutions and engineers each find their own path.

A quantitative trading firm explains itself to two audiences at once: institutions who want liquidity, and engineers who want hard problems. This concept builds one structure that serves both.
The existing site is confident and unusually well made — dense illustration, playful puzzles, a strong voice. What it does not have is a clear split between the institutional story and the recruiting story.
This concept keeps the firm's warm paper, its red and the hexagon that runs through its identity, and reorganises the surface: a plain-spoken homepage, a client page that reads like a capability sheet, and a culture section that stays human without becoming a brochure.
The homepage opens on the firm's own sentence, then immediately forks: one path for institutions, one for people who want to work here. Everything below is evidence for one of those two paths.

Institutional visitors arrive with a specific question: what can you trade, where, and at what size. The page answers in the first screen and keeps the numbers legible.
Jane Street
Continuous liquidity across asset classes, in size, in every major market — supported by the same technology and research that runs our own trading.

Culture pages usually list benefits. This one leads with how people actually spend a day — problems, puzzles, teaching — and puts the benefits where someone looks for them, near the roles.
Jane Street
Jane Street is a research-driven trading firm. Most of the day is spent explaining ideas to each other and taking them apart.
Trading, software engineering, research and the teams that keep the firm running.

The tile grid stacks to full-width blocks. Navigation is a dark sheet with the hexagon as the tap target, so the identity survives at 375px.
