Role Summary
We are seeking an experienced Smart Contract Developer to join our Digital Asset Development team. This is a hands on, security focused role responsible for designing, developing, testing, and deploying smart contracts that underpin institutional digital asset capabilities such as tokenisation, smart contract management, wallet management, and integration with blockchain infrastructure (public, permissioned and private EVM/non-EVM networks). You will work closely with cross-functional teams to build robust, scalable, and secure digital asset products that meet our business and technical requirements.

Role Description
Design and implement robust, efficient, and secure smart contracts for EVM and non-EVM networks, aligning contract behaviour with product and platform requirements.
Collaborate with product and engineering stakeholders to translate business logic into decentralized logic, ensuring correctness, resilience, and clear operational semantics.
Develop and maintain smart contracts supporting tokenization and life cycle operations, including patterns used for institutional needs (eg, permissioning/whitelisting and Proxy/upgrade approaches where required).
Build comprehensive unit and integration tests, and contribute to quality gates for contract releases. Perform internal security reviews and support external audits, proactively identifying and mitigating common smart contract vulnerabilities (eg, re-entrancy and front running classes of issues).
Own and evolve the smart contract toolchain (development environments, linting/static analysis, dynamic analysis, testing and audit readiness), ensuring tools are approved, integrated into the SDLC tollgates, and support consistent coverage and secure-by-design outcomes.
Build and maintain smart contract CI/CD workflows using existing build processes, integrating the contract repositories and pipeline stages needed to automate build/test/analysis artefacts and support controlled deployments in line with enterprise SDLC governance.
Contribute to engineering excellence through code reviews, documentation, and maintaining a high standard of security and quality in an iterative delivery environment.
Coordinate and partner with third party smart contract auditors by preparing audit-ready packages (scope, threat model context, code freeze/tag, and supporting artefacts), facilitating walkthroughs and Q&A, triaging findings with engineering, and driving remediation and re test cycles through to audit sign off and release readiness

Core/Must have skills
Strong, demonstrable experience developing smart contracts in Solidity or a similar language with a security-first mindset.
Experience across the smart contract life cycle: design, build, test, deploy, and maintain.
Experience with token standards and advanced token models, including partitioned or permissioned token approaches and Proxy/upgrade patterns.
Strong knowledge of secure coding practices for smart contracts and ability to identify/mitigate common vulnerability classes.
Proficiency with smart contract development and deployment tools (such as Hardhat) and modern testing patterns.
Understanding of EVM/Ethereum fundamentals (eg, smart contracts and EVM execution model)
Web3 integration experience, including using libraries such as Ethers.js/Web3.js to interact with smart contracts, sign/send transactions, and integrate contract functionality into dApps and services.
Blockchain cryptography fundamentals, including strong understanding of public/private key cryptography, signing/verification concepts, and the role of cryptographic mechanisms (eg, key management requirements and approved algorithms) in securing blockchain transactions and wallets.

Good to have skills
Experience building dApps and integrating front ends with smart contracts (eg, Web3 interaction patterns).
Familiarity with institutional digital asset platform components such as tokenization, smart contract management, wallet management, and integration patterns that connect on chain activity to off chain services.
Gas optimization and scalability techniques, including awareness of gas-related patterns/protocols (eg, Gasless transaction approaches such as OpenGSN).
Exposure to microservices and Back End integration in modern stacks (eg, NodeJS/Java/C#) and producing technical documentation for architecture and code.
Experience developing for non EVM smart contract platforms (eg, Canton/DAML or other non EVM chains such as Stellar or Solana), including adapting designs to different execution models, tooling, and network fee mechanics.

The Opportunity:

You’ll join an experienced, collaborative consultancy team delivering greenfield, enterprise-scale digital services for high-profile public and private sector clients.

This opportunity is ideal for a practical, adaptable Geospatial Software Engineer who enjoys working across disciplines and solving complex problems and challenges that will have a real-world impact.

Collaboration sits at the heart of how our client operates, so you’ll be partnering closely with colleagues across Software Engineering, User-Centred Design, Delivery Management, Data Science and Live Services to deliver outcomes that genuinely make a difference in today’s society.

As a consultancy, they are technology-agnostic by design, focusing on choosing the right tools for each problem, rather than forcing one stack everywhere.

Their teams regularly work with .NET, Java, Python, Node.js, AWS and Azure, giving you genuine scope to broaden your skills and develop your career across a range of languages and platforms.

Many of their projects also involve Geographic Information Systems (GIS) and open-source geospatial technologies, helping clients unlock the value of location-based data through mapping, spatial analysis and data-driven decision making.

Skills and Experience:

Essential

• 3+ years’ experience in a Full Stack Engineering role
• Strong development skills in .NET, Java or Python, alongside modern JavaScript frameworks/libraries
• Experience working in Agile environments (Scrum, Kanban, TDD)
• Solid understanding of architectural and design patterns, including microservices and serverless
• Hands-on experience designing and delivering solutions on AWS or Azure
• Experience working with GIS systems or geospatial data, and familiarity with tools such as Leaflet, OpenLayers, QGIS, GeoServer, PostGIS, etc.
• A collaborative mindset and experience working in multi-disciplinary teams

Desirable

• Experience working in a consultancy environment
• Exposure to public sector projects
• Familiarity with CI/CD tooling (eg Jenkins, Terraform)
• Awareness of the Digital Service Standard and Technology Code of Practice, particularly in geospatial or public sector contexts

Role and Responsibilities:

This is a varied role suited to someone who enjoys the pace, responsibility and collaboration of consultancy.

You will be involved with the following types of activity:

• Design and deliver high-quality solutions: building, enhancing and maintaining software, infrastructure and deployment pipelines that are robust, secure and scalable. Projects may include solutions involving geospatial data, GIS platforms and open-source mapping tools.
• Work collaboratively across disciplines: partnering with Senior and Lead Engineers, Delivery Managers, Designers and Data Scientists to shape solutions, contribute to technical documentation and deliver against agreed plans.
• Apply standards and best practice: follow established engineering approaches, contribute accurate technical estimates and proactively identify and escalate risks or issues.
• Communicate clearly and build relationships: present ideas, prototypes and progress updates to stakeholders, while building strong working relationships with colleagues, clients and partner organisations.

Applications:
