<p>Job brief: We are seeking a skilled Blockchain Developer to design, develop, and implement distributed ledger solutions. The ideal candidate will have hands-on experience with smart contracts, cryptography, and peer-to-peer networks. This role suits a pragmatic engineer who can balance innovation with production stability and collaborate with cross-functional teams to deliver secure, scalable blockchain applications.</p>
<h2>Blockchain Developer Job Profile</h2>
<p>The Blockchain Developer will lead development of decentralised applications, smart contracts, and backend infrastructure that interact with public or permissioned ledgers. They will ensure code quality, security, and performance while working with product owners and architects.</p>
<p>Reporting to the Head of Engineering, the role requires deep technical expertise and the ability to translate business requirements into robust blockchain solutions. Prior production deployments and a clear understanding of consensus algorithms are essential.</p>
<h2>Blockchain Developer Job Description</h2>
<p>As a Blockchain Developer, you will design, build, and maintain blockchain-based systems that support transactional integrity and transparent record keeping. You will author smart contracts, develop node software, integrate wallets and APIs, and create tooling for deployment and monitoring. Your day-to-day work will include writing clean, testable code, performing security reviews, and collaborating with DevOps to automate deployment pipelines.</p>
<p>You will analyse business processes to identify opportunities for distributed ledger technology, advise on appropriate architectures, and lead prototyping efforts. Responsibilities include evaluating consensus mechanisms, designing token models where required, and ensuring regulatory requirements such as data protection are addressed. You will mentor junior engineers and establish best practice coding standards, code review rituals, and documentation.</p>
<p>The role involves working across multiple technology stacks. You should be comfortable with backend development in languages such as Solidity, Rust, Go, or JavaScript, and experienced with cryptographic libraries, peer-to-peer networking, and database integrations. Strong communication skills are needed to present technical trade-offs to non-technical stakeholders and to work effectively with product, legal, and security teams.</p>
