· Implement logic to parse and execute JSON-based strategy DSL from the strategy builder.
· Design compute-optimized components for multi-asset workflows and scalable backtesting.
· Capture real-time state, performance metrics, and slippage for both live and simulated runs.
· Collaborate with infrastructure engineers to support high-availability deployments.
Top Technical Competencies
· Proficiency in distributed systems, concurrency, and system design.
· Strong backend/server-side development skills using C++, Rust, C#, Erlang, or Python.
· Deep understanding of data structures and algorithms with a focus on low-latency performance.
· Experience with event-driven and messaging-based architectures (e.g., ZeroMQ, Redis Streams).
· Familiarity with Linux-based environments and system-level performance tuning.
Bonus Competencies
· Understanding of financial markets, asset classes, and algorithmic trading strategies.
· 3–5 years of prior Backend experience.
· Hands-on experience with backtesting frameworks or financial market simulators.
· Experience with sandboxed execution environments or paper trading platforms.
· Advanced knowledge of multithreading, memory optimization, or compiler construction.
· Educational background from Tier-I or Tier-II institutions with strong computer science fundamentals, a passion for scalable system design, and a drive to build cutting-edge fintech infrastructure.
What We Offer
· Opportunity to shape the backend architecture of a next-gen fintech startup.
· A collaborative, technically driven culture.
· Competitive compensation with performance-based bonuses.
· Flexible working hours and a remote-friendly environment for candidates across the globe.
· Exposure to financial modeling, trading infrastructure, and real-time applications.
· Collaboration with a world-class team from Pomona, UCLA, Harvey Mudd, and Claremont McKenna.
Ideal Candidate
You’re a backend-first thinker who’s obsessed with reliability, latency, and architectural flexibility. You enjoy building scalable systems that transform complex strategy logic into high-performance, real-time trading actions. You think in microseconds, architect for fault tolerance, and build APIs designed for developer extensibility.
