Two Sigma

Two Sigma's internships hub names two principal tracks for undergraduate and early-masters candidates:

• Software Engineering Internship: a summer programme in New York City, with each intern paired to a mentor and owning a single project through to a final presentation
• Quantitative Research Internship: a summer programme working on alpha-modelling and statistical analysis of large datasets

For PhD-level candidates, the graduate students page lists a PhD Fellowship worth up to $160,000 across two years ($75,000 per year as an unrestricted university gift, plus a $10,000 direct stipend), a Masters internship in Quantitative Research and Data Science, and an annual invite-only "Discovery" PhD Symposium. The firm's undergraduate students page also lists a $15,000 STEM scholarship and the College Mentor Connect weekly mentoring programme. Every published early-career track skews research, quantitative, or systems-engineering — a candidate fitting this profile typically applies in parallel to other quant funds and research-led shops, not generalist banking schemes.

Two Sigma's About Us page reports a workforce of about 1,700, with more than 650 holding advanced degrees and over 250 holding PhDs. The firm was founded in 2001 by John Overdeck and David Siegel and managed approximately $70 billion at year-end 2025. It runs four distinct businesses — Investment Management, Securities (a broker-dealer / market-making arm), Sightway Capital (private investments), and Real Estate — so engineering and research roles are not confined to a single trading franchise. For a candidate weighing quant funds, the profile shifts the gate toward academic depth: research and technical credentials carry disproportionate weight at the application stage, and the firm signals consistently toward PhD and graduate-school programmes.
