Job DescriptionSenior Backend Engineer - Perpetual/Derivatives Platform (SunCrypto)
NJaipur (in office) | 4–8 years
NWe are building India's next-generation crypto derivatives venue: a perpetual futures platform where every microsecond, every satoshi and every state transition has to be right. We're hiring a senior backend engineer to own the core of that system.
NAbout SunCrypto
nSunCrypto is an FIU-IND registered Indian cryptocurrency exchange (Angelic Infotech Pvt. Ltd., FIU registration VA00031314), headquartered in Jaipur. We run a regulated spot exchange serving Indian retail and institutional customers, and we are now expanding into derivatives, starting with perpetual futures built in-house by a small, senior engineering team that reports directly to the CTO.
NWe operate under the Prevention of Money Laundering Act and India's VDA tax regime. That shapes how we engineer: auditability, reconciliation and exactly-once accounting are product requirements, not afterthoughts.
NThe role
nYou willdesign,



build and operate the backend services behind our perpetual futures product: the order lifecycle, position and margin engine, real-time market data fan-out, liquidity and hedging integrations with global venues, and the ledger that ties it all together.
NThis is a hands-on seniorindividual-contributor role with real architectural ownership. You will write code most days, review the code of others, be on the on-call rotation for the systems you ship, and be trusted to make technical decisions that a CTO would otherwise have to make.
NThe problems are hard in the way exchange problems are hard: hot paths that cannot block, balances that must never drift, and a market that never closes.
