Company Overview

The organisation operates within the fintech and blockchain technology sector, developing digital financial infrastructure that supports cryptocurrency services, blockchain-based transactions, and secure digital asset management.

Its technology operations focus on wallet infrastructure, blockchain connectivity, transaction processing, asset movement, and the development of secure software components for digital financial applications.

Role Summary

The Digital Asset Wallet Infrastructure Developer will contribute to the engineering of wallet-related systems used to manage digital asset transactions and blockchain connectivity. The position involves developing backend services, integrating blockchain networks, implementing transaction workflows, and improving the reliability of digital asset infrastructure.

The successful candidate will help build software components responsible for wallet operations, transaction creation, blockchain communication, address validation, and transaction status monitoring. A strong understanding of backend engineering, blockchain architecture, and secure financial application development will be essential.

This position is suited to a developer interested in building practical blockchain infrastructure rather than focusing exclusively on smart contract development.

Key Responsibilities

• Develop and maintain backend services supporting digital asset wallet operations.

• Build blockchain integration components that communicate with supported cryptocurrency networks.

• Implement transaction creation, signing workflows, broadcasting, and confirmation monitoring.

• Develop services for wallet address generation, validation, and transaction history retrieval.

• Integrate blockchain nodes and external blockchain data providers with internal financial applications.

• Implement transaction status tracking and notification mechanisms.

• Develop monitoring tools for blockchain connectivity, transaction processing, and wallet service availability.

• Support secure key management integrations and appropriate access control mechanisms.

• Investigate failed blockchain transactions, network connectivity problems, and transaction confirmation delays.

• Implement automated tests covering wallet operations and blockchain integration workflows.

• Collaborate with cybersecurity specialists to identify and address infrastructure vulnerabilities.

• Optimise backend services for reliability, performance, and transaction processing efficiency.

• Maintain technical documentation for wallet services, blockchain integrations, and infrastructure components.

• Participate in architecture discussions and contribute to improvements in digital asset platform reliability.

Requirements and Qualifications

• Bachelor’s degree in Computer Science, Software Engineering, Blockchain Technology, or equivalent professional experience.

• Experience developing backend applications and financial technology infrastructure.

• Proficiency in Python, Go, JavaScript/TypeScript, Java, or a comparable programming language.

• Practical understanding of blockchain architecture, distributed ledgers, and cryptocurrency transaction workflows.

• Familiarity with blockchain RPC interfaces, node connectivity, and transaction broadcasting.

• Knowledge of wallet infrastructure, public and private key concepts, and cryptographic signing principles.

• Experience working with REST APIs, databases, and asynchronous processing systems.

• Understanding of secure software development and sensitive credential management.

• Familiarity with Ethereum, Bitcoin, or other blockchain ecosystems.

• Experience with Docker, Git, and cloud-based deployment environments.

• Strong debugging, analytical, and problem-solving abilities.

• Ability to work independently in a distributed software development environment.

Benefits

• Fully remote working opportunity within Estonia.

• Opportunity to develop infrastructure for digital asset and blockchain financial services.

• Exposure to cryptocurrency wallet technologies and blockchain integration systems.

• Collaborative environment involving blockchain engineers and fintech specialists.

• Opportunities for technical growth in digital asset infrastructure and financial software engineering.

• Participation in challenging projects involving secure transaction processing and distributed systems.

Application Instructions

Interested candidates should submit an updated CV outlining their backend development experience, blockchain integration knowledge, and relevant software engineering projects. Applications should highlight practical experience with wallet infrastructure, blockchain APIs, transaction processing, and secure financial application development.
