Top Tech Jobs & Startup Jobs in London

Maintain and evolve on‑prem and cloud Linux infrastructure across compute, storage, and networking. Build and integrate platform tooling, automate operations, debug production incidents, perform upgrades/migrations, and consult with teams on Linux systems and host networking.

Design and build models, strategies, and systems to price and trade financial instruments. Work with researchers, engineers, and traders on dataset generation, time-series analysis, feature engineering, model building, hyperparameter tuning, and distributed/deep-learning training at large scale.

Internship working on real ML projects with full-time mentors: train models, develop or improve ML libraries and workflows, use large GPU clusters, and apply ML to noisy financial data while learning production ML engineering practices.

Intern will be paired with full-time engineers to build production-quality software, learn OCaml (and sometimes Python), and work on diverse projects from trading systems to language design under close mentorship.

Work with full-time researchers to identify market signals, analyze large datasets, design experiments, generate datasets, perform time-series analysis, engineer features, build and test models, and help create and productionize trading strategies. Participate in classes, seminars, and collaborative learning activities.

Internship building FPGA or ASIC hardware projects using OCaml and Hardcaml for RTL design and testing. Work includes using vendor toolchains (Vivado/Quartus/Genus/Innovus), mentorship from full-time engineers, and delivering a working hardware design from concept through integration.

Work alongside full-time ML researchers on end-to-end projects using large market datasets and massive compute. Tasks include model design, implementation in Python and ML frameworks, hyperparameter tuning, debugging training issues, and analyzing model predictions for systematic trading challenges in nonstationary multi-agent environments.

Work alongside salespeople and sales-traders to support institutional client engagement across asset classes. Learn how client inquiries are handled, service clients and issuers, attend internal training on finance and trading fundamentals, and develop analytical, communication, and relationship-building skills in a fast-paced environment.

Participate in a 10–12 week Strategy and Product internship solving cross-functional business problems, conducting structured data-driven analysis, building frameworks, and working with mentors on real projects to inform strategic initiatives.

This role requires managing financing transactions, developing relationships with brokers, optimizing financing strategies, and conducting cost-benefit analysis on financing opportunities.
