Quantitative Trader Jobs in Quebec (NOW HIRING)

About the job TS Imagine builds the trading and analytics infrastructure that powers some of the largest buy-side and sell-side institutions in the world. We are looking for a Lead Quantitative Snowflake Developer to join our Models and Quantitative Data team in Montreal - the senior technical anchor who owns the data foundations behind TradeSmart, our execution and trading analytics platform. You will build the quantitative datasets, AI pipelines, and analytics that detect signals, identify liquidity, evaluate best execution, benchmark transaction costs, and surface alpha opportunities across equities, credit, FX, fixed income, commodities, crypto, and their derivatives.

This is big data at scale. We work with trillions of price interactions, full-depth order book history, and global multi-asset tick data - the kind of volume where every architectural decision matters. Why this role is different We are an AI-First organization We always try to use AI first.

If it does not make sense or does not work, we do differently. Since 2023, we have managed humans and digital agents as one team - not a future-state aspiration, our operating model. Every workflow you build will be designed to be executed, evaluated, and extended by both people and agents.

Reference implementation for Snowflake and its AI capabilities We are one of the major consumers of Snowflake Cortex Code globally. We collaborate directly with Snowflake's product and research organizations as a design partner on Cortex Code, Cortex Analyst, Semantic Views, and AI Observability. Time-series at real-time scale with OneTick We leverage OneTick from One Market Data for large-scale time-series analytics performed in real-time - tick-level market microstructure, intraday execution analysis, and live signal computation across global venues.

State-of-the-art stack, used daily Snowflake, dbt, Python, SQL, Claude, OpenAI, Cortex Code, TruLens, OneTick. Not pilots. Production workflows that ship to the largest trading firms in the world.

TradeSmart focus Execution analytics, liquidity discovery, best-execution evaluation, transaction cost benchmarks, alpha signals. The data and AI you build directly shape how our clients trade. Built for engineers who like hard problems Trillions of rows.

Real-time constraints. Multi-asset complexity. If applied mathematics at scale is what you want to spend your time on, this is the role.
