Innovation Quant Developer Intern (DeFi/Corporate Development) - Brussels

Innovation Quant Developer: Intern - DeFi/Corporate Development

Since 2017, Keyrock has been a change-maker in digital assets. We're a global, remote-first team of 200+ people across 40+ nationalities, with hubs in Brussels, London, Paris and New York.

We provide liquidity across 80+ centralized and decentralized exchanges - a position cemented by our Series C, led by SC Ventures. Today we run a full spectrum of capital markets businesses across centralized and on-chain venues: market making, high-frequency trading, options, OTC, DeFi trading desks, advisory, and asset management.

We're building toward the agentic investment banking capabilities for the era of digital finance. A proprietary agentic layer runs the mechanics of the market, so our people can focus on the work code cannot do: the deal, the relationship, and the judgement.

We're not just envisioning the future of finance - we're building it.

Our internship programme gives early-career talent the opportunity to build practical skills, contribute to meaningful projects and learn alongside experienced colleagues in digital finance.

Typically lasting six months and based in our Brussels office (London possible), each internship includes hands-on experience, clear learning goals and dedicated guidance and regular feedback. We look for curiosity, relevant foundational skills, deep, active interest and passion for digital assets and the potential to grow exponentially with us - you don’t need to arrive with all the answers. Where performance, business needs and available opportunities align, an internship may lead to a permanent role, though this is not guaranteed.

We are looking for 3-4 high-caliber Quantitative Analyst Interns to sit within our Linear Market Making, DeFi trading , Credit/curation and Corporate Development desks/teams (see other openings on our career page for details).
Application deadline: 30 November 2026
Start date: 1 March 2027

• Interview with Talent Acquisition representative

• Interview with Hiring Manager
