This is a unique opportunity to work on a modern, performance-driven application emphasising clean architecture, maintainability, and innovation. We’re a team of curious, collaborative engineers excited to learn and contribute across the stack.

Position Overview

Key Responsibilities

  • 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.
  • 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.
