Profectus are working with the creative and digital powerhouse behind some of the most forward-thinking brands in the UK. Based in Scotland, our clients’ projects span media, publishing, fintech, political campaigns, and blockchain innovation.
Our client is currently hiring 2 x Blockchain Developers to join their in-house tech team in Scotland. These are in-person roles, based in Edinburgh, and will focus primarily on building a custom, ground-up blockchain to serve as the foundation of a new financial technology platform with integrated gold and silver-backed assets.
About the Role
As a Blockchain Developer, you’ll be at the heart of designing and building a completely new blockchain protocol — not a fork or clone — with original architecture, consensus mechanisms, and cryptographic systems. You’ll collaborate on core infrastructure, protocol design, and tools to support nodes, wallets, and ecosystem components.
This is a unique opportunity to build something entirely new, with significant autonomy and real-world impact in a mission-driven, entrepreneurial environment.
Key Responsibilities
- Architect, develop, and optimise a custom blockchain protocol from the ground up
- Design and implement consensus algorithms (PoS, PoA, hybrid, or novel approaches)
- Develop peer-to-peer networking layers and cryptographic modules
- Write clean, efficient, and secure low-level code in Rust, Go, C++, or similar languages
- Design node software and tools for transaction validation, block creation, and state management
- Develop supporting SDKs, APIs, and explorer tools for developers and integrators
- Collaborate on wallet development and secure transaction signing processes
- Perform rigorous code reviews, stress tests, and security audits
- Stay informed about emerging protocols, Layer 1 innovations, and performance tuning techniques
What We’re Looking For
- Minimum 3+ years of hands-on blockchain development experience, preferably at the protocol level
- Deep understanding of distributed systems, consensus algorithms, and P2P networking
- Proficiency in Rust, Go, or C++, and must demonstrate low-level development skills
- Experience building or contributing to Layer 1 protocols or significant blockchain infrastructure
- Strong understanding of cryptography, secure key handling, and hashing algorithms
- Familiarity with architecture of Bitcoin, Substrate, Tendermint, Cosmos SDK, or similar is a plus
- Experience with CI/CD workflows, GitHub version control, and testing frameworks
- Self-starter mindset with an ability to think both strategically and architecturally
- Comfortable working in a small team with autonomy and accountability
Benefits
- Competitive salary circa £150,000 (rising to £250,000 after probation), based on experience and demonstrated skills
- Be part of a greenfield project building a sovereign blockchain from the ground up
- Real-world application in financial systems backed by physical precious metals
- Work from a central office in Edinburgh
- Join an ambitious, values-driven team at the intersection of finance, tech, and innovation
To apply, please submit your CV along with a GitHub profile or portfolio that includes contributions to blockchain protocols, cryptographic projects, or distributed systems.
Our client is an equal opportunity employer. They choose to value talent, innovation, and dedication over titles and traditional backgrounds.
