Software Engineer (.Net Core) for Digital Assets (Hiring Immediately) in London

ZILO is focused on transforming the global asset management sector to create sustainable value for firms and the customers they serve. ZILO's technology enables firms to replace legacy technology and end-of-life systems, reducing costs and risk. This digital transformation journey requires strong partnerships with our customers to modernize and expand their product and service propositions by unifying transfer agency, fund platforms, and fund accounting into a single global solution. Our team brings together specialist expertise in asset management operations, digital assets, and large-scale technology delivery, with a shared passion for driving impactful, real-world change through secure, compliant innovation.

We are looking for a Software Engineer (.NET) to help design and deliver ZILO’s digital assets and fund servicing platform. You will build and maintain modern web applications, creating interactive user interfaces with Blazor and robust backend services in C#, so that asset managers and transfer agents can operate seamlessly across onchain and offchain processes. You will collaborate closely with other engineers, product managers, designers, and subject-matter experts in asset management and digital assets to translate complex fund and investor workflows into intuitive, secure software experiences. Your work will directly support mission-critical capabilities such as investor onboarding, token issuance, dealing, and reporting across multiple jurisdictions, helping global firms move away from legacy systems to a unified, digital-first model.

Responsibilities:

• Develop and maintain user-facing features and APIs for ZILO’s tokenisation and fund servicing platform using .NET 9, Blazor, and C#.
• Collaborate with cross-functional teams (engineering, product, UX, and subject-matter experts in asset management and digital assets) to design, build, and test secure, scalable software components.
• Write clean, efficient, well-tested and well-documented code that is straightforward to operate in production and audit across onchain and offchain workflows.
• Produce and maintain technical design documents and sequence diagrams that clearly describe service boundaries, data models, and integration points with smart contracts and external providers.
• Troubleshoot, debug, and optimise applications across the full stack, helping to maintain high availability and performance for mission-critical fund and investor processes.
• Stay up to date with emerging trends, tools, and best practices in .NET, cloud-native, and Web3-adjacent development, and bring practical recommendations into the team.
• Participate in code reviews, pair programming, and engineering ceremonies, contributing to a positive, inclusive, and learning-oriented team culture.
• Ensure features are delivered on time, to a high standard of quality, and in line with stakeholder, security, and regulatory requirements across our target jurisdictions (UK, Luxembourg, Ireland, US).

Requirements:

• Bachelor’s degree in Computer Science, a related technical field, or equivalent professional experience.
• Proven experience as a .Net / C# developer building production web applications and services.
• Strong proficiency in C#, HTML and CSS and modern front-end frameworks, ideally including Blazor.
• Experience designing and building microservice-based systems; exposure to micro-frontends or modular UI architectures is a plus.
• Solid understanding of RESTful APIs, asynchronous programming, and integration patterns; familiarity with GraphQL is beneficial.
• Experience with messaging and streaming technologies (for example Kafka or equivalents) for event-driven architectures.
• Hands-on experience with ASP.NET Core, unit testing frameworks, and CI/CD pipelines using Git-based workflows.
• Strong problem-solving skills, attention to detail, and a structured approach to debugging and optimisation.
• Ability to work independently within a distributed team, collaborating effectively with product, design, and operations stakeholders.
• Clear verbal and written communication skills, comfortable documenting designs and discussing trade-offs with technical and non-technical colleagues.
• Curious, proactive mindset with a willingness to learn about digital assets, blockchain concepts, and the asset management domain.
• Familiarity with Solidity and EVM is highly beneficial for understanding how our smart contracts and onchain components operate and integrate with the wider platform.

Benefits:

• Private healthcare plan - family covered
• Pension plan - salary sacrifice
• Life assurance
• 38 days annual leave (includes flexible bank holiday)
