Douro Labs builds market data infrastructure used across decentralized finance. The engineering team develops backend systems, smart contracts, SDKs, monitoring tools, and open-source components that support Pyth-related products.

In this Software Engineer role, you’ll work on both on-chain and off-chain projects, contribute to developer-facing tooling, and participate in shaping product direction alongside partnerships and business teams. The position requires strong software fundamentals, user-centric development practices, and comfort operating in a startup environment. Engineers at various seniority levels are considered, and responsibilities will be adjusted accordingly. The role is globally remote with an optional office in Porto.

🔹 Responsibilities

• Design, build, and maintain Pyth-related on-chain and off-chain systems, including smart contracts, SDKs, and utility programs.
• Collaborate with business development and sales teams to influence product direction.
• Mentor junior engineers and contribute to high-quality software design and documentation.
• Engage with external developers to understand requirements and produce SDKs, tools, and clear documentation.

🔹 Requirements
