Join Coinbase in Portugal & Secure the Future of Web3

Coinbase, a global leader in cryptocurrency innovation, is hiring a Blockchain Developer in Lisbon to advance its Web3 security and smart contract infrastructure. This is a high-impact role for experienced blockchain engineers looking to work on critical security features for decentralized finance (DeFi), digital identity, and crypto asset management.

International candidates are welcome, with full support through Portugal's Tech Visa—a fast-track immigration pathway for high-skilled tech professionals administered by the Portuguese government's immigration authorities.

About the Role

You will be part of a dedicated blockchain security team working on secure smart contract frameworks, auditing tools, and protocol-level protections that safeguard Coinbase and its user base in the evolving Web3 landscape. This position sits at the intersection of cryptographic security, decentralized systems, and real-world threat response.

Key Responsibilities

  • Develop and secure blockchain-based applications and smart contracts (Solidity, Vyper, etc.)
  • Conduct vulnerability assessments, audits, and threat modeling for DeFi protocols
  • Collaborate with backend, security, and protocol teams on decentralized architecture
  • Implement best practices in key management, data privacy, and secure contract deployment
  • Monitor and respond to real-time threats and zero-day vulnerabilities
  • Contribute to open-source security tooling for the Web3 community

Ideal Candidate Profile

  • 3+ years' experience in blockchain or smart contract development
  • Strong knowledge of Ethereum, EVM, Layer 2 protocols, and DeFi ecosystems
  • Proficiency in Solidity, Rust, Go, or TypeScript
  • Experience with tools like Hardhat, Foundry, MythX, and Slither
  • Passion for Web3 security, cryptography, and protocol integrity
  • Eligible for or seeking sponsorship under Portugal Tech Visa program

  • Salary: €90,000–€130,000 per year plus equity options
  • Full support for the Portugal Tech Visa (fast-track residence permit)
  • Relocation assistance for international candidates
  • Remote-first work culture with access to Portugal's growing Web3 ecosystem
  • Learning budget and access to open-source projects and leading conferences
  • Competitive benefits package and professional development opportunities

Why Work in Portugal?

Portugal has emerged as a top destination for remote tech professionals and blockchain developers. The country is ranked among the best for digital nomads and tech talent, offering a combination of professional opportunity and quality of life. Key advantages include:

  • Fast and efficient Tech Visa pathway for non-EU developers, administered through Portugal's immigration authority
  • Thriving blockchain and Web3 community centered in Lisbon
  • Affordable cost of living compared to other Western European tech hubs
  • Strong expat network and excellent quality of life
  • Access to Europe's broader tech and fintech ecosystem

Relevance for NRI and Indian-American Tech Professionals

This opportunity is particularly significant for Indian-origin tech professionals and NRIs seeking to expand their careers beyond the United States and traditional tech hubs. For Indian-American blockchain developers, Portugal offers a strategic alternative to the competitive H-1B visa landscape in the United States. The Portugal Tech Visa provides a streamlined pathway that does not rely on lottery-based systems or employer caps, making it an attractive option for skilled professionals from India.

The Indian diaspora has a strong presence in blockchain and cryptocurrency development, with many NRI engineers contributing to major Web3 projects globally. This Coinbase role in Lisbon allows Indian-American developers to leverage their expertise while gaining European residency and access to the EU market. Additionally, Portugal's growing Web3 ecosystem creates networking opportunities with other diaspora members and global blockchain innovators.

For NRIs considering relocation from the United States, Portugal offers tax advantages for new residents and a pathway to EU mobility, which can be valuable for long-term career planning. The salary range of €90,000–€130,000, while lower than comparable U.S. tech roles, aligns with Portugal's cost of living and provides strong purchasing power. Many Indian professionals have successfully transitioned to Portugal's tech sector and report positive experiences with visa processing and integration into the local tech community.
