About Biconomy

Biconomy empowers Web3 developers to build seamless, user-friendly dApps that work effortlessly across multiple blockchains. Our battle-tested modular account and execution stack eliminates traditional UX friction points, helping projects accelerate user adoption while reducing development costs. By processing over 70 million transactions across the 300+ dApps we've served, we're powering the future of onchain economies.

About The Role

HyperSignals is Biconomy’s high-performance analytics and trading platform. Our goal is simple but ambitious: turn fragmented market data into actionable, onchain trading strategies across spot and perpetual futures.

You’ll work across backend infrastructure, smart contracts, and frontend tooling to create a unified trading stack that integrates with leading perp protocols. Your work will directly power execution, risk management, and strategy deployment for a new class of decentralized trading applications.

What You Will Be Doing

Design robust backend services that connect to perp order books, manage trading flows, and expose APIs for our frontend and quant teams.

Develop data pipelines that capture and process real-time market activity, from order books to liquidations, enabling accurate PnL, funding, and risk insights.

Build and deploy smart contracts that support trade execution, account abstraction, and settlement, with a focus on security and performance.

Optimize trading infrastructure to achieve low-latency execution, efficient order routing, and scalable liquidity management.

Collaborate with product, data, and frontend teams to deliver intuitive trader-facing interfaces and strategy management tools.

Stay ahead of the curve on perp protocol design and DeFi infrastructure to ensure HyperSignals remains best-in-class.

Requirements

4+ years of professional software engineering experience, including 2+ years in Web3 or DeFi.

Strong backend development skills in Node.js, Rust, Go, or similar.

Practical experience with data engineering concepts (streaming systems, event-driven architectures, SQL/NoSQL databases).

Hands-on smart contract development (Solidity, Rust, or Vyper), with a strong appreciation for secure coding practices.

Familiarity with perpetual futures mechanics: funding rates, leverage, margining, liquidations, and order book dynamics.

Experience integrating with exchange APIs (REST, WebSocket, gRPC).

Proven track record of shipping production systems at scale.
