Senior Software Engineer (Applied Cryptography)

Douro Labs is at the forefront of Web3 development. We help decentralize data services and enhance access to real-time, once-exclusive market data for all blockchain participants by contributing to some of the most important projects in the space, such as the Pyth Network, where we are one of the initial contributors.

Douro Labs is looking for a talented Engineer who has exceptional knowledge in the area of Applied Cryptography, someone who understands cryptographic algorithms and has implemented them in software previously, as they are building a blockchain and want to implement a threshold signing system for the validators so that other chains can easily validate the state of this chain.

About the Team and Your Role:

• We're a balanced team; half of us are tech-talented people, while the other half excel in forging partnerships with data providers, developers, and the DeFi community - Communication is key in our network-driven approach.
• Work remotely: Our team spans the globe from the US and South America to Europe and Asia, with an optional office in Porto, Portugal. Remote work is our norm.
• English proficiency is essential as it's our medium for team and external developer communication.
• Thrive in a startup environment within the dynamic DeFi space. We value adaptable problem solvers eager to address evolving market needs.
• Write open-source software: Check out our open-source projects on GitHub for a sneak peek into our work.
• User-centric development: Our success hinges on external developers engaging with our solutions—crafting user-friendly APIs and crystal-clear documentation that aligns with developers' needs.

Desired Skills and Experience:

• At least 4 years of software engineering experience, with a bonus for experience in large-scale, safety-critical systems.
• Smart contract and blockchain development is beneficial but not mandatory. For those without blockchain experience, we like to see backend engineering experience and an understanding of low-level programming languages (such as Rust or C++).
• A zest for fast-paced, startup-like environments, adapting swiftly to the ever-changing DeFi market.
• Keenness to learn or experience with Rust, Solidity, Python, and Typescript.
• Exceptional technical communication skills for diverse interactions within and outside the team.
• Ability to nurture engineers of varying skill levels.
• Willingness to manage periodic on-call responsibilities.
