Quantitative Developer - Multi-Strategy - NYC - Builder role - 4-person pod - CRO visibility - Up to $750k TC
Mondrian Alpha is a global, multi-strategy trading firm managing over $28B in assets. They are seeking a Quantitative Developer to join a small engineering pod focused on building core risk and attribution infrastructure, enhancing portfolio-level analysis, and directly collaborating with risk managers and senior stakeholders.
Responsibilities
Core risk and attribution infrastructure: PnL explain, factor and sector exposure, scenario analysis
High-volume data processing systems (batch and near-real-time) where performance and correctness matter
Shared internal tools used across the firm for portfolio-level analysis and senior-level reporting
Greenfield extensions of systems already in demand—the role exists because the tooling worked and usage scaled rapidly
Qualification
Required
Very strong Python with real performance intuition (profiling, memory, concurrency trade-offs)
Solid CS fundamentals: algorithms, data structures, systems thinking
Ability to reason from first principles—understanding why something works, not just how to implement it
Engineers from quant funds, trading firms, HFTs, or similarly demanding environments
People who've built end-to-end systems, not just thin wrappers or glue code
Clear signals of technical depth: open-source work, competitions, serious side projects, strong CS background
Preferred
Bonus if you've worked closer to the metal (C++ / Java / C#) even if Python is your day-to-day
Open to non-finance backgrounds if engineering quality is exceptional
