Senior Fullstack Engineer

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.

The Role – Powering The Next Generation Of Real-Time Market Intelligence

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.

We’re looking for a Senior Fullstack Engineer to take a leading role in building this system end to end. 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.

What We Offer

• Innovative Work Culture – Join a team that’s at the cutting edge of Web3, AI, and DeFi, and help shape the future of the digital economy
• Fun and Engaging Team Activities – Game nights, virtual celebrations, and work retreats to keep things exciting
