| Level | Years | Base (p50) | Equity/yr (p50) | Bonus (p50) | Total (p25-p90) |
|---|---|---|---|---|---|
| E1Software Engineer (New Grad) | 0-2 YOE | $190K | $2K | $110K | $250K - $440K |
| E2Software Engineer | 2-5 YOE | $220K | $2K | $160K | $310K - $590K |
| E3Senior Software Engineer | 5-9 YOE | $250K | $5K | $250K | $400K - $840K |
| E4Lead Software Engineer (Staff-equivalent) | 8-14 YOE | $285K | $5K | $380K | $510K - $1.2M |
Entry-level. First-year bonus is typically guaranteed in the offer. Pays below Jane Street / HRT new-grad numbers but above almost every product company.
Mid-level. Two Sigma runs more like a structured tech company than a trading desk - bonus targets are more predictable than at pure prop shops, with correspondingly lower ceilings.
Senior IC. The most-common external hire level. Engineers on modeling-platform and live-trading systems land the upper band; corporate-engineering roles track p25-p50.
Staff-equivalent. Some seniors receive deferred-compensation awards invested alongside the funds (reflected in the small equityAnnual band) - vesting is typically 3 years.
The entry level for a Two Sigma Software Engineer in this dataset is E1 - Software Engineer (New Grad) (0-2 YOE). Median total compensation is $302K, with the 25th-90th percentile at $250K-$440K; the median package is $190K base, $110K bonus, $2K equity a year.
This dataset has no separate signing-bonus figure for Two Sigma, so none is published here. What it does record: the first-year bonus is typically guaranteed in the offer, and new-grad pay sits below Jane Street and HRT but above almost every product company.
The median annual bonus for a Two Sigma Software Engineer runs from $110K at E1 to $380K at E4, which is 36% of the median package at E1 and 57% at E4. Cash (base plus bonus) is 99% of the median package at both E1 and E4.
There is no stock. Pay is base salary plus a discretionary bonus that tracks fund performance, so the spread between the 25th and 90th percentile widens with seniority. Bonus targets are more predictable than at pure prop-trading shops, with lower ceilings. Senior engineers also receive deferred-compensation awards invested alongside the funds (the small equity column), typically vesting over three years.

Two Sigma Software Engineer levels and median total compensation - E1 - Software Engineer (New Grad): $302K; E2 - Software Engineer: $382K; E3 - Senior Software Engineer: $505K; E4 - Lead Software Engineer (Staff-equivalent): $670K. The E-levels are informal; Two Sigma does run a real level and manager structure, unusual among quant firms.
No. Two Sigma pays base salary plus a discretionary bonus. The small equity column in this dataset reflects deferred-compensation awards invested alongside the funds, standard at senior levels and typically vesting over three years.
Two Sigma's loop is two onsite coding rounds, a data- and ML-infrastructure system design round, a team-specific domain round and a behavioral round; some phone screens add a statistics probe. The prep pack lays out each round and what to practise for it.
Two Sigma Software Engineer prep pack7 rounds. 6 of them can be practised here - each one below links the rep that trains it.
Recruiter screen
30 minutes. Background, level calibration, team alignment - Two Sigma recruits across modeling/research engineering (Python, ML infrastructure, feature stores, research compute), data engineering (time-series storage, distributed compute, data quality), trading platform (JVM-heavy, low-latency, market connectivity), and core platform (infrastructure, observability, security).
Technical phone screen
60 minutes. One coding problem at Medium difficulty in your language of choice - Python and Java most common. Some interviewers include a probe for statistical or data-manipulation reasoning if you've been matched to a research-flavored team.
Free rep: Coding challenges with a real sandbox →Onsite: coding round 1
60 minutes. Algorithmic problem with attention to clean implementation and edge cases. Trees, graphs, hash maps, intervals, and array/string manipulation common. Cleanliness and explicit narration matter as much as the algorithm.
Free rep: Coding challenges with a real sandbox →Onsite: coding round 2
60 minutes. Often more applied - extend an existing data pipeline component, build a small piece of research infrastructure, debug a snippet with a subtle data-handling bug. For research-engineering candidates, may involve statistical reasoning or data-manipulation depth.
Free rep: Coding challenges with a real sandbox →Onsite: system design
60-75 minutes. Data and ML infrastructure flavored. Common prompts: design a time-series store that supports petabyte-scale historical data with sub-second query latency, design a distributed compute platform for quant research workloads, design a feature store that supports both training and low-latency serving, design market-data delivery for trading systems with strict latency budgets. Depth on data layout, partitioning, latency budgets, and the research workflow expected.
Free rep: Design walkthrough: Design a Distributed Cache (Memcached / Redis Cluster) →Onsite: domain depth or research collaboration
60 minutes. Team-specific. Research engineering: how do you collaborate with quants, what does a typical research workflow look like, how do you measure whether your infrastructure is helping research move faster. Trading platform: low-latency systems engineering, market connectivity, JVM tuning. Data engineering: time-series storage internals, distributed compute (Spark, Dask, Two Sigma's internal frameworks), data quality at scale.
Free rep: What this round looks for →Onsite: hiring manager / behavioral
45-60 minutes. Research-engineer collaboration focused. Stories about working closely with non-engineering domain experts (data scientists, researchers, analysts), translating ambiguous research needs into engineering work, navigating tradeoffs between exploratory research speed and production reliability. Generic 'I'm a team player' answers fail.
