About Us
Manifold Technologies is a quantitative trading firm building systems that curve with the market’s geometry. We don’t chase trends—we curve the field until structure reveals itself. Most systems collapse when curvature shifts. Ours adapts because it is built from within. Bayesian inference and differential geometry aren’t frameworks we borrow—they are the native language of our architecture.
We’re hiring an experienced Quantitative Research Engineer to help guide the next phase of the system’s evolution. This role goes beyond implementation. You’ll work directly with the founders to shape internal structure, clarify abstractions, and extend the system through recursive feedback. You’ll operate across both mathematical and engineering layers—owning core components and identifying structural bottlenecks as the system continues to evolve.
This is a co-founder-level opportunity for someone who leads through reasoning, not hierarchy. We don’t need a manager—we need someone who holds the field clearly enough that others naturally align around it.
What We’re Looking For
You’ve worked in serious trading or research environments—whether at firms like Jane Street, Citadel, HRT, Two Sigma, Jump, or similar—or in performance-critical systems at top-tier tech companies. You’ve touched live systems. You’ve made decisions that mattered.
You don’t just write code—you shape systems. You know when to move fast—and when moving fast would break the structure you’re holding. You’ve guided others—not through authority, but through how you think. You’re rigorous with what you build, open with what you don’t know, and capable of reasoning through systems where structure governs behavior, not heuristics.
Responsibilities
Architect and implement components within our system’s recursive foundation, from curved input logic to order execution
Own high-leverage infrastructure while helping offload implementation once structural clarity has emerged
Work directly with the chief executive and other senior researchers to compress structure, surface what holds, and bend abstraction into implementation
- Clarify complexity by holding structure clearly enough that alignment becomes inevitable
Own performance, stability, and structural alignment of the system under live market conditions
Qualifications
3+ years of experience in quantitative trading, research engineering, or high-performance systems
Deep programming fluency (Python required; Bash/Java/C++ optional but welcome)
Comfort with asynchronous systems, concurrency, and real-time performance constraints
Strong mathematical intuition; able to reason in geometry, probability, and information space
Academic pedigree (e.g., Stanford, MIT, Berkeley, CMU, etc.) is valued—but secondary to field-tested capability
Compensation
Compensation for this role is highly competitive and includes a base salary, year-end performance bonus, and meaningful equity incentives structured for long-term ownership and co-founder alignment. Additional benefits—such as health coverage, wellness stipends, or retirement contributions—may be included based on the final offer.
