We're an early-stage product company building an AI-powered analytics platform for the iGaming industry. Users get answers from their data in plain English — an LLM turns questions into validated SQL over a large data warehouse — alongside a set of analytics dashboards and data pipelines. It's live in production.

You'd be our first dedicated engineer, working directly with a technical founder (product) and an experienced CTO (architecture + code review) — with a real path to Tech Lead as the team grows. You won't be flying solo, and you'll help shape the architecture, not just maintain it.

What you'll do

• Build and ship features across the backend and the dashboard.

• AI: Anthropic Claude (natural-language → SQL, agent workflows).
• Frontend: React 18 + TypeScript + Vite, shadcn/ui + Tailwind, TanStack Query, Recharts.
• Infra: Azure, Redis, Docker, GitHub Actions.

Note: the data-science/ML models are owned by the founder — you won't build or maintain those.

You'll thrive here if you have

• Strong SQL and relational-DB skills (Postgres a plus) — the single most important thing.
• Solid Python, ideally with an async framework (FastAPI).
• Good React + TypeScript.
• A correctness-first instinct for data, and the ability to pick up a fast-built codebase and make it solid.

• Comfort with cloud + CI/CD (Azure a plus) and Docker.

   

Nice to have

• LLM app experience (Anthropic/OpenAI, NL→SQL, RAG).
• Data engineering / BI / warehousing background.
• iGaming, fintech, or marketplace domain experience.

Why join

• A live, revenue-generating product — early enough to shape it.
• A clear growth path to Tech Lead.
• Modern stack: large data warehouse + production LLM pipeline + polished React app.
• Real support: a technical founder on product, an experienced CTO on engineering.

We are looking for a Lead Backend Developer to architect and own the backend infrastructure of our fintech platform. You will design scalable microservices, manage critical data flows, and ensure system reliability at scale. Work directly with product, design, and business stakeholders to translate requirements into robust backend systems.

What You Will Do
Backend Architecture & Design

• Own the backend architecture end-to-end across microservices.
• Design and implement Node.js / Express services handling 20M+ transactions monthly.
• Architect PostgreSQL schemas for reliability and performance at scale.
• Define API contracts (GraphQL, REST) that support frontend and partner integrations.
• Make critical decisions on data consistency, caching, and async patterns.

Microservices & System Design

• Build and maintain multiple Node.js / Express microservices with clear ownership boundaries.
• Implement webhook-driven workflows and event-driven architecture.
• Design and implement real-time data synchronization pipelines.
• Manage message queues (RabbitMQ) for async operations and inter-service communication.
• Ensure row-level security (RLS) and multi-tenant data isolation at the database layer.

Data & Performance

• Design and optimize PostgreSQL schemas using Prisma ORM.
• Write complex queries, manage indexes, and ensure query performance.
• Implement caching strategies and data consistency patterns.
• Build audit trails and changelog tracking for compliance and debugging.
• Handle sensitive data (KYC, AML, financial records) with security-first approach.

Integration & Third-Party Services

• Integrate with external services (KYC providers, document verification, acquiring networks).
• Design and maintain API integrations with payment processors and clearing centers.
• Build robust error handling and retry logic for critical integrations.
• Document APIs and maintain SDK/integration guides for partners.
Communication & Leadership

• Work directly with product managers and stakeholders to clarify backend requirements.
• Proactively flag technical risks, propose solutions, and keep stakeholders informed.
• Give technical feedback on product feasibility and scalability implications.
• Lead backend code reviews with focus on quality, performance, and knowledge sharing.
• Mentor junior developers and foster backend engineering best practices.

What We Are Looking For
Core Requirements:

• 5–7 years of production experience in Node.js backend development.
• Strong TypeScript across the entire stack (no JavaScript-only experience).
• PostgreSQL expertise: schema design, optimization, transactions, advanced queries.
• Prisma ORM or similar ORMs and hands-on experience with relational databases.
• GraphQL schema design and resolver implementation (REST a plus).
• Microservices architecture: designing boundaries, managing state, async communication.
• RabbitMQ or similar message brokers; event-driven architecture patterns.
• Experience with fintech, payments, or regulated financial products.
• Strong communication skills and comfort working directly with non-technical stakeholders.

Nice to Have:

• Distributed systems experience (eventual consistency, saga patterns, consensus).
• gRPC for service-to-service communication.
• Experience scaling to 100K+ users and handling high transaction volume.
• Background in AML/KYC compliance or financial data handling.
• DevOps sensibility: monitoring, logging, deployment pipelines.
• Experience mentoring backend teams.

Tech Stack
Core: Node.js, Express, TypeScript, PostgreSQL, Prisma ORM, GraphQL, RabbitMQ, gRPC
Supporting: REST APIs, Webhooks, Real-time data sync, Multi-tenant architecture, Audit logging

What We Offer

• Full backend ownership and architectural control.
• Work on systems handling millions of transactions and 100K+ merchants.
• Direct access to product and business stakeholders.
• Modern microservices stack with no legacy debt.
• AI-friendly engineering culture—we embrace tools that make you more effective.
• Deep fintech learning: multi-partner networks, compliance, payment flows.
• Competitive compensation and benefits package.
