Backend Engineer (NestJS / TypeScript)
Location: Remote - Tehran
Start: Immediate
Compensation: Competitive + Equity
About the Role:
We’re building a fast, modular NestJS + GraphQL backend powering a modern e-commerce and Web3-enabled platform. You’ll work on core backend architecture, scaling features, event-driven flows, integrations (auth, payments, search, Web3, AI), and real production deployments.
We move quickly, keep things practical, and expect engineers to think independently.
Core Requirements:
Backend:
- Solid knowledge of NestJS fundamentals (modules, guards, interceptors)
- Familiarity with GraphQL, microservices patterns, message queues
- Good command of TypeScript
- Ability to debug using source code, not just documentation
- Experience with multi-auth flows (JWT, OAuth, multi-step identity)
- Experience integrating multiple payment systems
Message brokers:
- Comfortable with working with messaging brokers such as Rabbit MQ
- Exposure to AI integration (Highly recommended) for queueing and productizing (AI development is not part of this role, but productizing an existing AI model as a service in the backend system is)
Data & Storage:
- Strong with PostgreSQL
- Practical use of Redis
- Bonus: Typesense or Elasticsearch
Architecture:
- Comfortable with event-driven design
- Modular, maintainable code structure
- Practical (not enterprise-heavy) DDD understanding
DevOps (Practical Musts):
- Deploying Node/NestJS apps on Linux
- Basic Nginx configuration
- SSL setup and renewal
- Using Docker
- Debugging server issues (logs, performance, connectivity)
Nice to Have:
- Experience with e-commerce or transactional systems
- Basic understanding of Blockchain/Web3 and handling on-chain events
- Familiarity with monitoring tools
- Familiarity with Web UI and Android (Kotlin) UI workflows from working alongside frontend/mobile teams
What Matters Most:
- Ability to understand English (reading docs, APIs, RFCs)
- Strong problem-solving attitude
- Ownership mindset and comfort with fast decision-making
- Curiosity and willingness to dig deep into unfamiliar systems
