University Recruiter About Graviton : Graviton Research Capital is a global quantitative trading and investment firm driven by technology, mathematics and rigorous problem-solving. We bring together exceptional talent across quantitative research, software engineering and technology to solve some of the most challenging problems in the industry.

What You Will Own Campus Talent Strategy & Ecosystem Building Build and maintain relationships with priority institutions (IITs, IIITs, BITS and relevant global universities), placement offices, faculty and student communities. Drive year-round engagement - events, technical talks and competitions — to strengthen Graviton's employer brand outside peak hiring windows. Assessment & Selection Coordinate (or design and standardize, at senior levels) rigorous selection frameworks in partnership with Tech and Quant teams — scheduling assessments, allocating panels, driving timely feedback, and building interviewer calibration mechanisms to keep evaluation objective and consistent.
