You will join the Hedging team as a Senior Backend Engineer, owning significant portions of the Risk Management Engine and Smart Hedging systems end-to-end. The Hedging team manages inventory and exposure, risk management, hedging positions across venues through smart routing strategies, market making, cost calculation, and PnL/net revenue computation. Every client trade creates exposure; this team decides what to hold, what to hedge, where to hedge it, and what it costs.
Key responsibilities include designing and building services across the risk path (inventory tracking, hedge decisioning, venue routing, WAC/PnL/net revenue calculation); owning features end-to-end from scoping through operational health; driving work to closure with Product, Design, and Operations teams; acting as a product engineer to scope problems and understand product impact; building for correctness and timeliness on live risk paths; integrating with external venues and liquidity providers; designing smart routing strategies; instrumenting systems with logging, metrics, and alerting; designing for failure with retries, idempotency, and reconciliation; mentoring L1/L2 engineers; managing tech debt; participating in on-call and incident response; and collaborating with Trading, Treasury, and Finance teams.
Required qualifications: 4–6 years building and operating production backend systems; trading background (exchange, brokerage, or trading platform experience like CoinDCX, Groww, or CoinSwitch Kuber); strong system design, data modeling, and API design fundamentals with distributed systems experience; solid OOP and low-level design pattern knowledge; production engineering instincts (observability, debugging, performance tuning, incident response); comfort with precision in financial systems where approximate is unacceptable; ability to handle abstract, ambiguous problems; hands-on, high-agency approach; proficiency with AI coding tools; data-driven mindset; and clear written communication for async, globally distributed work.
Desirable experience includes hedging/exposure/risk management systems, multi-venue execution, smart order routing, market making, PnL/cost-basis/position-keeping logic, FX/multi-currency systems, cross-border payments, market data, order books, and market microstructure.
