About LedgerLabs

LedgerLabs is building LedgersOS — the AI Operating System for Finance.

We are developing AI-native ERP infrastructure designed for:

• Crypto hedge funds
• Token foundations
• Digital asset businesses
• High-growth global startups

This is not another SaaS dashboard.

We are building financial infrastructure: AI-powered general ledger systems, treasury automation, real-time reconciliation, and intelligent financial agents.

Early-stage. Product-led. Execution-focused.

The Role

We’re looking for a strong Backend Engineer (Node.js) to architect and build the core systems behind LedgersOS.

You will work directly with the founder to design and implement:

• Scalable backend architecture for financial-grade workloads
• Secure APIs and modular microservices
• Multi-tenant data models and permissions frameworks
• Authentication, RBAC, and audit-trail systems
• AI service orchestration (LLM workflows, automation agents)
• Real-time data ingestion (wallets, exchanges, external APIs)
• Financial-grade database schemas (ledger design, transaction models)
• High-performance, secure, and reliable infrastructure

This is a core systems role — not feature maintenance.

You will be building the foundation layer of an AI-native financial platform.

What We’re Looking ForRequired

• 3+ years production experience with Node.js
• Strong TypeScript proficiency
• Experience building and maintaining production APIs
• Solid database design (PostgreSQL preferred)
• Experience with REST and/or GraphQL
• Understanding of backend security best practices
• Ability to think in systems, not just endpoints

Strong Bonus

• Experience in fintech, accounting systems, or crypto infrastructure
• Familiarity with ledgers, financial data models, or reconciliation logic
• Experience with real-time systems (WebSockets, queues, streaming)
• Experience integrating AI APIs (OpenAI, Claude, etc.)
• Cloud infrastructure experience (AWS, GCP, etc.)
• Experience handling high-integrity financial data

What You’ll Get

• Direct influence over core product architecture
• Early-stage equity upside
• High ownership and autonomy
• Remote flexibility
• The opportunity to build infrastructure used by modern finance teams and crypto funds
