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.

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.
