If you are a strong Full Stack JS Engineer who understands databases, system design, and performance — and you want to build something technically serious, not cosmetic — we would like to talk: [email protected]
About the Project
We are looking for Javascript engineers with solid experience in backend-heavy fullstack development, CRM platforms, and building enterprise-grade or industrial-scale systems.
We are developing an ecosystem that will encompass CRM, telephony, AI agents, chatbots, payment gateways, analytics modules, and related infrastructure.
❗This is a data-intensive, integration-heavy, performance-critical system.
We are looking for an engineer who understands architecture, scalability, and production responsibility — not just feature delivery.
What You Will Work On
- Design and implement scalable backend services in Node.js / TypeScript
- Architect and maintain systems handling high concurrency, heavy data processing, or large volumes of API integrations
- Design clean service boundaries and system architecture
- Build and optimize REST and GraphQL APIs
- Design and optimize PostgreSQL schemas, queries, and indexing strategies
- Implement data pipelines for validation, enrichment, scoring, and automation
- Integrate multiple third-party APIs (credit bureaus, enrichment providers, marketing tools)
- Optimize performance, reliability, and observability
- Work with modern AI tooling (AI-assisted coding, agent orchestration, workflow automation)
- Collaborate on CI/CD, containerization, and cloud deployment.
Required Technical Expertise
Core Requirements
- Strong, production-level knowledge of JavaScript / TypeScript
- Deep experience with Node.js
- Experience designing application architecture from scratch
- Experience building event-driven architectures and streaming data pipelines using Apache Kafka
- Experience designing and operating systems handling high concurrency, heavy data processing, or large volumes of API integrations
- Strong knowledge of PostgreSQL (schema design, performance tuning, indexing, query optimization)
- Experience building scalable REST APIs
- Understanding of distributed systems concepts (caching, queues, message/event streaming, idempotency, concurrency control)
Additional Plus
- Experience with Next.js / React
- Experience with Snowflake or similar data platforms
- Docker / Kubernetes
- AI-driven workflows, LLM integrations, or agent orchestration systems
What We Expect
- Architectural thinking — ability to see system-level consequences
- Ownership mindset — you build it, you care about how it runs
- Ability to work with ambiguity and evolving requirements
- Pragmatic approach to AI tools (we use AI to accelerate development, not to replace engineering judgment)
- Clear communication in English
Work Format & Compliance

- You must have:
- Legal authorization to work remotely from your country of residence
- Valid residence status
