Product Engineer - BackEnd

TL;DR: Seeking an experienced Back-end Developer (Product Engineer) with expertise in blockchain technology to build and scale the Proof-of-Skill protocol, a decentralized system for skill verification and credentialing.

Proof of Skill protocol is a blockchain-based system where industry experts (Validators) evaluate candidates' skills and issue verifiable Skill Credentials. Organizations can then shortlist candidates based on these credentials.

Qualifications and Skills:

5+ years of experience in back-end development, with a strong focus on blockchain technology

Proven track record of building and scaling decentralized applications (dApps) or blockchain-based products

In-depth understanding of blockchain architectures, consensus mechanisms, and smart contract development

Proficiency in programming languages such as Solidity, Rust, Go, or other relevant languages for blockchain development

Familiarity with various blockchain platforms (e.g., Ethereum, Polkadot, Cosmos, Solana) and their respective ecosystems

Experience with decentralized storage solutions (e.g., IPFS, Filecoin) and decentralized identity protocols

Strong knowledge of cryptocurrency wallets, token standards (ERC-20, ERC-721), and blockchain security best practices

Familiarity with decentralized finance (DeFi) concepts is a plus

Responsibilities:

Design and develop the core back-end components of the Proof of Skill protocol, including smart contracts, blockchain integration, and off-chain services

Implement secure and efficient data storage and retrieval mechanisms for skill credentials and validator information

Develop and integrate decentralized identity solutions for validators and candidates

Ensure the scalability, performance, and security of the protocol as it grows

Collaborate with cross-functional teams, including front-end developers, UX designers, and product managers

Stay up-to-date with the latest blockchain technology trends and advancements

Contribute to the project's technical documentation and knowledge-sharing initiatives

Ideal Candidate Traits:

Strong problem-solving and critical thinking skills

Ability to work independently and as part of a team

Excellent communication and collaboration skills

Passion for decentralized technologies and their potential impact

Entrepreneurial mindset and willingness to take ownership

High agency and a drive for continuous learning and improvement

If you have a deep understanding of blockchain technology and a passion for building innovative, decentralized solutions, we invite you to join our team and contribute to the future of skill verification and credentialing.
