posted by: spj_bot

Senior Backend Engineer (Intents & Order Infrastructure)

Location: Remote - Based in EMEA regions
compensation: $130K - $165K

We are simplifying multi-chain DeFi for traditional financial institutions, fintechs, and service providers. Our platform offers a unified API to access all on-chain liquidity across major blockchains, ensuring the best prices for same-chain and cross-chain swaps. We are a passionate, remote-first team on a mission to enable a fairer, more decentralized world by making complex blockchain technologies accessible to everyone.

We are looking for a Senior Backend Engineer to lead the development and scaling of our core off-chain coordination service. This is a critical infrastructure role, as the Order Server acts as the central hub for the entire Intent lifecycle—from quote aggregation and validation to real-time broadcasting and cross-chain status tracking.

In this role, you will build secure, high-throughput systems using TypeScript and NestJS that allow applications to discover competitive quotes while protecting the network from fraudulent orders. This position is vital for the success of our solver-based architecture and requires a deep focus on security, performance, and reliability.
