Position Overview
We’re looking for a Mid-Level Full-Stack Developer with solid experience in SvelteKit, JavaScript/TypeScript, and CSS/HTML (experience with Shoelace is a plus). You’ll play a key role in building and optimising a feature-rich loan management system, covering borrower onboarding, application processing, repayment tracking, CRM integration, automated reporting, and investor dashboards. This is a great fit for someone who thrives in a fast-paced, remote-first environment and is excited about decentralised architectures and financial tech.
Key Responsibilities
Develop, maintain, and optimise front- and back-end components using TypeScript/JavaScript (and potentially Rust).
Implement features like repayment tracking, investor dashboards, and automated financial reporting.
Build and maintain integrations with Zoho CRM, including borrower onboarding, notifications, and portfolio monitoring.
Work with Atomic Server to support decentralised data architecture and real-time updates.
Collaborate with the product and design teams to translate business needs into scalable, maintainable technical solutions.
Ensure accurate financial data flow, seamless monitoring, and compliance-grade reporting.
Write clean, testable code and participate in code reviews, debugging, and documentation.
Develop APIs for third-party integrations (e.g., Zoho CRM, payment gateways).
Required Skills & Experience
3–5 years of full-stack development experience.
Strong proficiency in JavaScript/TypeScript and modern front-end frameworks (preferably SvelteKit).
Solid experience with CSS/HTML; knowledge of Shoelace UI components is a plus.
Interest or experience in Rust and decentralised data systems like Atomic Server, JSON-LD, or JSON-Atomic Data.
Experience working with APIs and NoSQL databases; cloud-based deployment is a plus.
Understanding of domain-driven design (DDD) is a strong advantage.
Exposure to financial systems, loan management platforms, or investor reporting tools is helpful.
Familiarity with financial reporting standards (IFRS, GAAP) is a bonus.
Comfortable using Git, CI/CD pipelines, and writing clear code documentation.
Excellent attention to detail — especially in working with sensitive financial and portfolio data.
Nice to Have
Experience working on regulated or compliance-heavy systems.
Familiarity with decentralised or semantic web technologies.
Passion for building ethical, impactful financial technologies for underserved markets.
What’s in It for You?
Work on a cutting-edge, AI-driven platform with real-world impact.
Join a small, agile, remote-first team with high ownership and flexibility.
Opportunity to work across the stack and grow into more senior roles.
Flexible contract with the potential for extension or permanent placement.
