What You’ll Do
We’re looking for exceptional senior ICs who combine strong product leadership with deep quantitative skill.
You should demonstrate:
- Quantitative Product Ownership
- Devise and own a highly consistent, coherent, and principled quantitative direction across trading, margining, liquidation, lending, and risk-related products.
- Ensure that individual models, parameters, and mechanisms fit together into a harmonious system, rather than a collection of locally-correct but globally-fragile designs.
- Own the end-to-end correctness, feasibility, and desirability of quantitative products in production.
- Take ownership over preventing tricky edge cases, stress scenarios, and failure modes from hitting production.
- Act as the first line of defense for user, partner, and internal feedback related to quantitative behavior:
- answering questions about correctness and intent
- diagnosing whether feedback reflects misunderstanding, edge cases, or real design flaws
- driving fixes or adjustments when models do not behave as intended
- Treat post-launch behavior as a continuation of product design, continuously refining models based on observed outcomes and feedback. Biasing strongly towards system consistency during revisions, and avoiding repeated fragile patches.
- Cross-Functional Leadership & Execution
- Act as the product owner for quantitative surfaces that are inherently difficult for others to reason about.
- Write exceptionally clear, precise specifications that engineers can implement correctly and safely.
- Translate complex quantitative concepts into explanations appropriate for each audience:
- simplified mental models for users and partners
- implementation-level clarity for engineers
- risk and trade-off framing for leadership
- Own alignment-driving end-to-end:
- proactively surface concerns, disagreements, and edge cases
- address feedback thoughtfully rather than deferring or waiting for others
- drive conversations to clear decisions and committed direction
- Take direct responsibility for validating implementations of quantitative products:
- design and execute deep testing in non-production and production environments
- reason about edge cases, stress scenarios, and failure modes that others are unlikely to catch
- use QA support where helpful, but remain personally accountable for correctness
- Own the outcome when quantitative products are mis-implemented, even if gaps were not caught by QA, recognizing that the domain complexity requires quant-level validation.
- Operational Ownership & Risk Management (Primary, High Bar)
- Take first-class oncall responsibility for quantitative systems and risk-sensitive product behavior in production.
- Act as a key responder during incidents involving:
- abnormal trading behavior
- liquidation anomalies
- margin, risk, or insurance fund issues
- extreme market conditions or tail events
- Be accountable for real-time decision-making during high-stakes situations, including:
- diagnosing root causes under pressure
- advising on mitigations, parameter changes, or temporary safeguards
- balancing user impact, platform safety, and long-term risk
- Lead or co-lead post-incident analysis for quantitative failures, ensuring:
- root causes are correctly understood (model vs implementation vs assumption)
- durable fixes are made to models, parameters, or system design
- learnings are fed back into product design and operational playbooks
- Proactively identify latent systemic risks and work with engineering and risk teams to reduce them before they manifest as incidents.
- Design quantitative products with operability in mind, including:
- observability of key metrics and invariants
- explainability of system behavior during abnormal events
- safe failure modes and bounded blast radius
We’re looking for exceptional senior ICs who combine strong product leadership with deep quantitative skill.
You should demonstrate:
- Prior experience building or operating trading venues, exchanges, or market infrastructure.
- A strong background as a quant, trader, or financial modeler, with hands-on experience designing or validating trading or risk models.
- Proven strength as a Product Manager, including:
- owning outcomes end-to-end
- driving cross-functional alignment
- writing high-quality, precise specifications
- Deep understanding of margining, liquidation, leverage, and systemic risk mechanics.
- Strong operational mindset and comfort owning systems in production.
- Excellent communication skills, especially when explaining complex quantitative reasoning clearly.
- Sound judgment under ambiguity and high-stakes decision-making.
