Specialist Search · Quantitative Engineering

High performing engineers, placed at the top quantitative trading firms in New York.

Selective mandates. High ownership. Operated in partnership with Evolve Group. We work with engineers who care where their code ends up and firms that pay for that depth.

Four core archetypes. Every brief sits inside one of them.

01 Trading Systems

Quantitative Developer (Trading Systems)

Low latency execution engines, order book infrastructure, and the production trading stack that takes strategies into live markets. Where microseconds and P&L meet.

02 Research Infrastructure

Quantitative Developer (Research Infra)

Simulation engines, backtesting frameworks, feature stores, and model serving systems that quant researchers run on. The bridge between research and production.

Python Simulation engines Feature stores Model serving
03 Distributed Systems

Software Engineer (Distributed Systems)

High throughput backend services, batch and streaming data infrastructure, and the platform components engineers across the firm depend on. Built to scale.

Selective, technical, end to end.

01

Live feedback loops

Direct lines with the recruiters at every firm on our roster. Interview feedback in days not weeks. Scheduling, prep, and decision timing handled end to end. Never left in the dark.

02

Technical depth

Conversations grounded in the actual stack, the actual work, and the actual people you would be sitting next to.

03

White glove relocation

Handled end to end for candidates outside NYC. Moving costs, flights, temporary housing, and visa support.

04

High ownership

Every candidate works directly with Vellion x Evolve. Every brief understood and agreed upon before a resume goes to any of the 16 firms. Dedicated prep with us ahead of every interview round.

Built for engineers who care where their code ends up.

Vellion is a specialist search firm dedicated to quantitative engineering and systematic trading. We focus on a narrow band of roles, run a narrow band of mandates, and work with engineers who would rather solve the hardest problem in the building than the easiest problem with the loudest title.
