Apply on Susquehanna International Group’s siteSusquehanna International Group are running this same intake in Dublin. Each one is a separate advert with its own application form, so applying in London does not put you forward for the others.
Public data and the employer’s own words, not immigration advice. Whether a role can be sponsored also turns on its salary, the Skilled Worker thresholds in force, and your own status.
Susquehanna hires students and graduates in the UK into its London office at 25 Basinghall Street in the City of London. For 2027 entry it is advertising graduate roles including Trading Systems Engineer Graduate, Quantitative Strategy Developer Graduate and Software Developer Graduate, alongside summer internships in trading systems engineering, quantitative strategy development and equity research. The graduate roles are aimed at final year students and the internships at penultimate year students.
Susquehanna publishes no closing date on any of its London early careers adverts. Instead several of them say hiring is rolling and tell you to apply early. The Trading Systems Engineering internship advert says "We hire for our TSE internship on a rolling basis. There are limited places on our 2027 TSE internship, therefore interested candidates are strongly encouraged to apply early." The Quantitative Strategy Developer internship carries the same wording for its own programme, and on the graduate side the Quantitative Researcher advert says "We hire for our quantitative research positions on a rolling basis, therefore interested candidates are strongly encouraged to apply early." Each role is a separate advert and a separate application on the firm's own careers-sig.icims.com system, so applying to one does not put you in front of another team. We found no published reapplication rule on Susquehanna's own pages.
Susquehanna's own job pages carry a posting date in their page data. For 2027 entry, the London Quantitative Trading Internship, Quantitative Trader Graduate and Quantitative Researcher Graduate adverts are marked posted 15 July 2026, the Equity Research Internship 17 July 2026, and the Trading Systems Engineering internship, Quantitative Strategy Developer internship, Software Developer Graduate, Quantitative Strategy Developer Graduate and Trading Systems Engineer Graduate adverts 21 August 2026. Last cycle the equivalent London software role, Software Developer Graduate: 2026 (London Office), was posted 22 September 2025, so the 2027 software graduate advert opened roughly a month earlier than the year before.
