Shared Ledger Engineer (Blockchain / EVM)
\n
\nAt MindWave we’re not just building teams. We’re building a new way of working with an international community of experts who thrive in an innovative and people-first environment.
\nFor one of the world’s most strategic financial technology programs, we are looking for a Shared Ledger Engineer (Blockchain / EVM) to join a long-term international initiative.
\nThis project focuses on the next generation of blockchain-based shared ledger infrastructure designed to improve interoperability, security, resilience, and efficiency across global financial institutions.
\nYou’ll contribute to enterprise-grade distributed ledger systems with real-world global impact — helping shape foundational infrastructure that could influence how financial institutions transact and collaborate in the future.
\nThis is a remote-first position, with home working as the default setup. We also offer access to our Athens or Leuven office for those who enjoy occasional in-person collaboration and bimonthly in-person team events to keep the connection.
\n
\n📡 Your responsibilities will include:

\n\n

Designing, building, and maintaining distributed ledger applications supporting large-scale financial ecosystems
Developing and maintaining smart contracts for shared ledger workflows
Building backend services and APIs connecting blockchain platforms with enterprise systems
Working with EVM-based architectures and distributed ledger technologies such as Ethereum and Hyperledger Besu
Contributing to architecture decisions around scalability, interoperability, governance, resiliency, and privacy
Designing identity and permission frameworks using PKI, certificates, and role-based access controls
Ensuring solutions meet enterprise-grade standards around security, compliance, auditability, and reliability
Collaborating closely with architecture, DevOps, product, and security teams
Participating in technical design discussions, architecture reviews, and code reviews
Staying informed on emerging trends in blockchain infrastructure, distributed ledger technology, and financial market innovation

\n🧠 Your Profile\n\n

3+ years of professional software engineering experience
Proven production experience delivering blockchain solutions (beyond certifications, hackathons, or personal crypto projects)
Hands-on experience writing, deploying, testing, and maintaining smart contracts in production environments
Strong experience with EVM ecosystems and technologies such as Ethereum and Hyperledger Besu
Strong proficiency in Solidity
Experience with smart contract tooling such as Hardhat, Foundry, or similar frameworks
Strong understanding of distributed systems architecture
Strong understanding of smart contract security best practices
Experience integrating blockchain platforms with enterprise systems
Experience with cloud infrastructure, containers, Kubernetes, and CI/CD pipelines
Familiarity with enterprise blockchain frameworks and Linux Foundation ecosystems such as Hyperledger technologies
Experience within banking, payments, capital markets, or regulated fintech environments is a strong plus
Comfortable using modern engineering productivity tools, including AI-assisted development environments

\nWorking model
\nThis role involves close collaboration with teams operating on the US East Coast. To maximize overlap, candidates should be comfortable with a schedule that includes late-morning starts in Greece (typically around 10:00 AM local time or later).
\nOccasional travel to Belgium may be required for planning sessions, collaboration moments, or key project milestones. Travel is fully covered by MindWave and expected to remain limited to approximately one week per quarter.
\n
\nWhy join us?
\nAt MindWave, you won’t work on speculative crypto products or short-term hype projects.
\nYou’ll contribute to meaningful technology with real impact on global financial infrastructure, while collaborating with one of the most important organizations in the international financial ecosystem.

A growing international community of experts, with both spontaneous and planned knowledge sharing moments such as brown bag sessions (innovation and tech key notes) 🧠
