**Workplace:** on_site

## Description

**About the Role**

We are looking for a Senior Software Engineer with a strong combination of backend engineering depth, applied AI experience, and blockchain/digital assets expertise. This role sits at the intersection of enterprise fintech and emerging technology — you will be building and scaling systems that matter, in an environment where your work has real-world financial impact.

If you have spent years writing production-grade Node.js, have crossed into AI-integrated systems, and have hands-on experience with blockchain development and smart contracts — this role was built for you.

**What You'll Be Doing**

-   Designing and building scalable, high-availability REST and GraphQL APIs using Node.js and TypeScript
-   Integrating AI/ML capabilities into backend services and fintech workflows
-   Developing and deploying smart contracts for digital asset and crypto use cases
-   Contributing to blockchain architecture decisions, protocols, and digital asset infrastructure
-   Working within distributed microservices ecosystems — troubleshooting, optimizing, owning
-   Collaborating across CI/CD pipelines, containerized environments (Docker, Kubernetes), and cloud platforms (AWS/Azure)
-   Driving security-first development practices including JWT, OAuth, and SSO implementation
-   Operating in an Agile environment with cross-functional squads

## Requirements

**What You Need to Bring**

_Mandatory:_

-   8+ years of professional software engineering experience
-   5+ years of hands-on Node.js and JavaScript in production environments
-   Minimum 1 year in TypeScript
-   Demonstrable AI/ML integration experience in real production systems — not just familiarity
-   Blockchain development experience: smart contract development, digital assets, crypto protocols
-   Solid understanding of Kafka, message queues, and event-driven architecture
-   Experience with Docker and Kubernetes in production
-   REST API design and GraphQL proficiency
-   Banking, fintech, or financial services background strongly preferred  
    

_Strong advantage:_

-   Experience with Solidity or other smart contract languages
-   Exposure to DeFi protocols, tokenisation, or digital asset custody platforms
-   API gateway experience (3Scale or equivalent)
-   Familiarity with regulatory and compliance considerations in digital finance

**Education**

Degree or postgraduate qualification in Computer Science, Engineering, or a related field — or equivalent demonstrated experience.
