Role Description We’re looking for a Blockchain Engineer (Contractor) who enjoys solving complex technical problems, navigating ambiguity, and contributing to real-world products used by companies across the US and Europe. Engagement details - Contractor / project-based engagement - Paid in USD/hour - Remote-first - Flexible allocation depending on project availability and fit - Opportunities may vary in duration, scope, and weekly commitment depending on client needs Some opportunities may start immediately. Others may become active as new projects enter our pipeline. What this role actually looks like - Build and evolve blockchain infrastructure services that power production-grade digital asset platforms - Work closely with team members to figure out what should actually be built - Integrate backend systems with Layer-1 blockchains, ensuring reliability, scalability, and operational resilience - Build services such as blockchain indexers, event processors, chain APIs, wallet services, and transaction pipelines - Design and improve blockchain workflows around transaction execution, event monitoring, reconciliation, and failure recovery - Make trade-offs between scalability, security, observability, maintainability, and business priorities - Collaborate with international clients and multidisciplinary teams to shape technical solutions for security-critical blockchain products What tends to work well here - Have strong experience building or integrating blockchain infrastructure in production environments - Understand Layer-1 blockchain mechanics such as transaction lifecycle, confirmations, finality, forks, reorgs, and event propagation - Feel comfortable building backend services, APIs, event-driven systems, and distributed architectures beyond the blockchain layer itself - Have a fullstack mindset — even if blockchain and backend are your strengths, you're comfortable navigating adjacent technologies and collaborating across the stack when needed - Enjoy solving complex infrastructure problems where security, observability, and reliability matter as much as feature delivery - Feel totally confident working in English with international clients and teams (calls, discussions, async) — at least advanced level - Already use AI as part of their day-to-day workflow — whether for protocol analysis, development, debugging, documentation, testing, or workflow acceleration This probably won’t be your thing if - You’re looking for a highly stable long-term internal role with fixed scope and predictable allocation - You prefer highly structured environments with rigid processes and very defined requirements - You’re uncomfortable navigating ambiguity or fast-changing technical contexts - You’d rather avoid client interaction or cross-functional collaboration - You dislike context-switching between technologies, projects, and business domains One last thing To participate in this selection process, you must: - Have a valid business registration in your country (CNPJ, VAT, EIN, or equivalent) - Have a bank account eligible to receive USD payments - Be able to issue invoices accordingly - Be based in the USA These requirements are necessary for contractor engagement and payment processing.
