Three Different Firms
Citadel, Jane Street, and Two Sigma frequently appear together as "top quant employers," but they're structurally and culturally very different organisations. The right pick depends on your goals.
This guide compares them across the dimensions that matter for the decision.

| Type | Multi-strategy hedge fund + market maker (Citadel Securities) | Proprietary trading firm | Quantitative hedge fund |
| AUM / capital | 24B+ in regulatory capital | $14B+ trading capital | $60B+ AUM |
| Employees | ~3,000 across both | ~2,500 | ~2,000 |

| Public profile | High (Ken Griffin is publicly visible; political donations) | Famously private | Moderate (more public than Jane Street, less than Citadel) |
Citadel: The Multi-Strategy Empire
Citadel comprises two distinct entities sharing a brand:
Citadel (the hedge fund)
- Multi-strategy: equities, fixed income, commodities, credit, quant
- "Pod shop" model: portfolio managers run independent strategies; risk allocated centrally
- High turnover at PM level (formal performance evaluation; under-performers exit)
- Outside investor capital
- Leverage: high
Citadel Securities (the market maker)
- Separate entity, also founded by Griffin
- Market making across equities, options, fixed income, crypto, FX
- Widely described as generating very large revenue on strong days (often cited in media; private entities disclose limited detail)
- Heavy quant infrastructure
- Trading with the firm's own capital
Compensation
| Role | Year 1 total comp |
|---|---|
| New grad quant researcher | 500K |
| Citadel Securities new grad SWE | 700K |
| Senior researcher (5+ years) | 3M |
| Top portfolio manager (with 1B+ allocated) | 50M+ |
PM compensation is formula-driven (typically 15-25% of net P&L the pod produces). Top performers in big years can earn 100M+. Under-performers can be fired within 12-18 months of poor returns.
Culture
- Intense, performance-driven
- Less famously "fun" than Jane Street; less famously academic than Two Sigma
- Ken Griffin's personal stamp is visible (public visibility, political activity, large office investments)
- Recent move to Miami has reshaped the in-person culture
Best fit for
- Researchers who want maximum compensation potential
- Engineers who want to work at scale (Citadel Securities is often cited as handling a large share of US equity volume - exact percentages fluctuate; verify against current public commentary and filings)
- People comfortable with explicit performance pressure
- People who want exposure to the full range of strategies and asset classes
For specific Citadel coverage:
- Citadel salary
- Citadel internship
- Citadel interview (existing)
Jane Street: The Quiet Giant
Jane Street is the most secretive of the three but consistently the highest-paying at entry-level for technical roles. It's a proprietary trading firm focused on ETFs, options market making, and an expanding range of asset classes.
Business
- ETF market making (largest in the world)
- Options market making
- Crypto trading (significant revenue from this)
- Increasingly diversified
Compensation
| Role | Year 1 total comp |
|---|---|
| New grad SWE / quant trader | 700K |
| Senior trader (5+ years) | 5M+ |
| Senior partner / desk head | 50M+ |
Compensation is largely cash-based (no equity grants in the typical sense). Bonus structure is opaque even internally - you're told your number, but the formula isn't published.
Culture
- OCaml-heavy engineering (functional programming culture)
- Strong recruiting bias toward elite mathematics/CS backgrounds (IMO medalists, Putnam winners, etc.)
- Famously private - leadership rarely speaks to media
- Intellectual, math-puzzle-driven internal culture
- Significant in-person expectation (office presence valued)
- Strong focus on long tenure (less pressure than Citadel pods)
Best fit for
- Strong mathematical backgrounds (Olympiad-level)
- People who enjoy puzzle-solving and game-theoretic thinking
- People who prefer intellectual depth over flashy compensation upside
- People comfortable with NYC living and in-person work
For specific Jane Street coverage:
- Jane Street salary
- Jane Street internship
- SIG interview (similar prop trading firm style)
Two Sigma: The Engineering-Quant Firm
Two Sigma is the most "tech-company-like" of the three. Founded by ex-DE Shaw alums, it has a strong engineering culture that overlaps significantly with Bay Area tech firms.
Business
- Systematic strategies across multiple asset classes
- Long-term investment horizons (vs Jane Street's microstructure focus)
- Significant ML and alternative data investment
- Two Sigma Securities (separate market-making entity)
Compensation
| Role | Year 1 total comp |
|---|---|
| New grad SWE | 400K |
| New grad quant researcher | 500K |
| Senior researcher (5+ years) | 2M |
| Director / VP-level | 5M+ |
Two Sigma typically pays less than Jane Street and Citadel at entry-level but offers stronger work-life balance and more "tech-company" perks.
Culture
- Engineering-heavy (more like a top tech firm than a hedge fund)
- Significant remote/hybrid flexibility post-2020
- Lower performance pressure than Citadel pods
- More academic / research-paper-oriented than the other two
- Diverse hiring (more than Jane Street; comparable to Citadel)
Best fit for
- Engineers from tech backgrounds wanting to enter quant
- Researchers who value academic-style work environments
- People who want better work-life balance than the other two
- People interested in ML and alternative data
- People wanting NYC location with remote flexibility

How to Choose
If you have offers from multiple, the decision usually comes down to:
-
Comp at entry-level matters less than you think. All three pay enough that the marginal $50K is unlikely to determine your happiness or career trajectory.
-
Culture fit matters most. Visit each office, talk to junior employees, ask about a typical day.
-
Career narrative. Where do you want to be in 10 years? Citadel makes you a multi-strategy operator. Jane Street makes you a market-making specialist. Two Sigma makes you a ML-research-oriented quant.
-
Geography. Citadel HQ in Miami (with NYC presence). Jane Street in NYC, with London, Hong Kong, Amsterdam offices. Two Sigma in NYC primarily.
