Jane Street, Hudson River Trading, Two Sigma, Jump Trading, Optiver, and Susquehanna International Group (SIG) are the strongest employers for entry-level quant developers heading into 2026, ranked on training structure, tech stack transparency, and how often junior engineers move into research or trading seats.
- Jane Street tops the ranking of best employers for entry level quant developers in 2026 for its OCaml training pipeline.
- Hudson River Trading wins for low-latency systems roles; Two Sigma wins for research-adjacent development work.
- Optiver and Susquehanna (SIG) run the most structured rotational programs for new-grad quant developers.
- Tech stack transparency and promotion path into research or trading matter more than firm prestige alone.
Why this matters
Entry-level quant developer hiring is narrower than generalist software recruiting. These firms hire a small class of new grads each year and expect production-grade code plus enough market intuition to sit near a trading desk within months, not years.
Picking the wrong employer at 22 or 23 can lock you into pure infrastructure work with no path toward research or trading, which is why this ranking weighs career mobility as heavily as brand name heading into 2026. If you're weighing prop shops specifically, the best prop trading firms for entry-level quants guide breaks that subset down in more depth.
QuantMinds works with candidates targeting exactly these firms, and the pattern holds up: candidates who research a firm's actual tech stack and promotion path before applying land more offers than candidates who apply to every logo on a prestige list.
What makes the best employer for entry-level quant developers
- Structured onboarding. A defined training block beats a sink-or-swim first month.
- Tech stack transparency. You should know before you sign whether you're writing OCaml, C++, Python, or all three.
- Career mobility. Can a developer move into research or trading, or is the dev track a dead end.
- Interview process fit. Does the process test skills you can actually prepare for, or is it a black box.
- Mentorship ratio. How many junior engineers sit under each senior engineer or trader.
- Retention signal. Do engineers stay past the two- to three-year mark, or churn out fast.

1. Jane Street: best employer for entry-level quant developers for deep language training
Jane Street builds nearly everything in-house in OCaml and runs every new hire, including candidates with zero functional programming background, through a multi-week internal training block before they touch production code. The firm blurs the line between quant developer and trader more than most shops on this list, so junior engineers get exposure to the trading floor early.
Jane Street pros:
- Internal OCaml training removes the learn-it-yourself burden most firms skip
- Junior engineers sit close to trading desks, not walled off in a separate infra team
- Strong reputation among MFE and CS recruiters for technical rigor
Jane Street cons:
- The functional-programming stack is a real adjustment coming from Python or C++ only
- Interview process leans on OCaml-style problem sets that differ from standard coding-round prep
Best for: engineers willing to learn a new language stack in exchange for close trading-floor exposure. Verdict: Apply, if you're comfortable with a steep first-90-days learning curve.
2. Hudson River Trading: best employer for entry-level quant developers for low-latency systems work
Hudson River Trading runs one of the more clearly defined infrastructure tracks in the industry, with junior engineers working on order routing, market data handling, and latency reduction from day one. The culture skews quieter and more engineering-first than trading-floor-style shops.
Hudson River Trading pros:
- Clear infrastructure and latency track for engineers who want systems work, not markets analysis
- Culture leans toward engineering depth over trading-floor intensity
- Strong internal tooling and testing discipline
Hudson River Trading cons:
- Narrower rotation into research or trading roles than firms built around cross-training
- Best fit for a specific technical interest, less useful if you're still deciding what you want long-term
Best for: engineers who already know they want low-latency systems work, not a generalist path. Verdict: Apply, if systems and networking excite you more than markets.
3. Two Sigma: best employer for entry-level quant developers for research exposure
Two Sigma structures its engineering org around close collaboration with research and data science teams, so quant developers frequently build the pipelines researchers use to test signals. It's one of the larger quant shops on this list, which means more structure but more layers between a junior hire and firm-wide strategy decisions.
Two Sigma pros:
- Daily contact with research and data science, useful if you eventually want to move toward research
- Larger scale means more established mentorship and documentation than a smaller shop
- Broad platform exposure across asset classes and strategies
Two Sigma cons:
- Size slows the path to ownership compared to a smaller prop trading firm
- More process and review layers before code ships
Best for: developers who want a bridge toward quant research without leaving engineering yet. If you want to go deeper on research-track employers beyond Two Sigma, the hedge funds hiring quant researchers guide covers that path directly. Verdict: Apply, if you want research adjacency now and optionality later.
4. Jump Trading: best employer for entry-level quant developers for hardware-level work
Jump Trading invests heavily in custom hardware, FPGA work, and network engineering that goes deeper into the physical layer than most quant shops touch. Entry-level developers here often specialize early rather than rotate broadly.
Jump Trading pros:
- Rare exposure to FPGA and hardware-level optimization most software roles never touch
- Small, technically dense teams mean fast feedback on your code
- Compensation-through-performance culture typical of top HFT shops
Jump Trading cons:
- Specialization happens fast, which narrows your resume if you later want to pivot to research
- Interview process tests low-level systems knowledge most CS curricula don't cover well
Best for: engineers who already know they want to go deep on hardware and networking, not broad exposure. Verdict: Apply, if hardware-adjacent work is the specific itch you want to scratch.
5. Optiver: best employer for entry-level quant developers for formal training
Optiver runs one of the more structured new-grad onboarding programs among prop trading firms, rotating junior hires through multiple teams before locking in a permanent seat. That structure suits candidates who aren't fully certain whether they want the dev side, the trading side, or somewhere in between.
Optiver pros:
- Formal rotation gives exposure to multiple teams before committing to a track
- Reduces the risk of getting stuck on a poor-fit team long-term
- Global offices add some flexibility on location if that matters to you
Optiver cons:
- Less say in your initial team assignment than firms that hire directly into a specific role
- Rotation programs take longer to reach full project ownership than a direct-hire track
Best for: candidates who want structured exposure before specializing. Verdict: Apply, if you value a guided first year over immediate ownership.
6. Susquehanna International Group (SIG): best employer for entry-level quant developers for early ownership
SIG organizes around small trading pods, and junior developers on those pods often touch production-critical code within months, not years. The tradeoff is less formal mentorship infrastructure than a firm built around a dedicated training cohort.
Susquehanna pros:
- Small pod structure hands real ownership to junior engineers fast
- Generalist culture rewards engineers who pick up trading logic quickly, not just software skills
- Flatter reporting lines than the larger quant shops on this list
Susquehanna cons:
- Less structured mentorship than Optiver's rotation model or Jane Street's training block
- Fit depends heavily on the specific pod you land on, which varies more than firm-wide programs
Best for: engineers who want ownership on day one and don't need a formal training runway. Verdict: Apply, if you're confident enough to learn on the job with less scaffolding.
How to prepare once you've picked a target list
None of these firms accepts unprepared candidates. Jane Street and Hudson River Trading lean on take-home coding tests plus live pairing sessions; Optiver and Susquehanna run in-person case interviews on probability and mental math alongside coding rounds. Working through a structured quant interview prep guide before you apply closes most of the gap between a strong resume and an actual offer.
How this ranking was built
The six criteria above get weighted differently depending on where you sit in your career. A first-year master's student cares more about structured onboarding than a candidate who already shipped production code during an internship. A training program that takes a year to reach full ownership isn't a red flag by itself — it signals the firm invests in juniors instead of churning them, which is exactly what Optiver's rotation and Jane Street's OCaml block do.

Which employer should you choose?
Apply to Jane Street first if you're comfortable learning OCaml under pressure — the training pipeline and trading-floor proximity are hard to match elsewhere on this list heading into 2026.
If functional programming isn't your thing, Two Sigma is the stronger default for developers who want a research pivot to stay open, given the daily contact with data science teams.
Still undecided between infrastructure and trading logic? Optiver's rotation buys you a year to figure that out before committing.

FAQ
What is the best employer for entry-level quant developers in 2026?
Jane Street tops the list in 2026 for its structured OCaml training pipeline and early trading-floor exposure for junior engineers. Hudson River Trading and Two Sigma follow closely depending on whether you want low-latency systems work or research adjacency.
Is Hudson River Trading better than Jane Street for a quant developer?
It depends on your interest, not overall quality. Hudson River Trading wins for low-latency systems work; Jane Street wins for broader trading-floor exposure and language training.
Do entry-level quant developers need a PhD?
No. Most of the firms on this list, including Jane Street, Optiver, and Susquehanna, hire directly from MFE and strong bachelor's programs for developer roles. A PhD matters more for research-track hires than developer-track hires.
How do I prepare for a Jane Street or Hudson River Trading interview?
Practice functional programming problem sets for Jane Street and systems design fundamentals for Hudson River Trading. Working through a structured quant interview prep guide before you apply closes most of the gap.
What's the difference between a hedge fund and a prop trading firm for a quant developer?
Hedge funds like Two Sigma manage outside investor capital and pair developers closely with research teams. Prop trading firms like Jump Trading and Optiver trade the firm's own capital and lean more toward infrastructure and execution speed.
Does an MFE degree help land these roles?
Yes. Most firms on this list recruit heavily from MFE and top STEM master's programs, though strong bachelor's candidates with the right coding background get in too.
How early should I start networking for these roles?
Recruiting for entry-level quant developer roles often opens well over a year before the start date, so outreach during the first year of a master's program isn't too early.
Which firm has the most structured training program for new grads?
Optiver's multi-month rotation is the most formally structured onboarding among the prop trading firms on this list, ahead of Jane Street's OCaml training block.
One last thing
The line between quant developer and quant researcher is blurring fast at firms like Two Sigma and Susquehanna, and a resume that only lists "software engineer" language undersells a candidate who's already touched signal research in a prior internship. That framing gap shows up in coaching sessions far more often than firm selection does, and it's usually the cheaper fix of the two.
