Senior Fullstack Developer (Python Backend + React)

Location: Israel (Hybrid) | Type: Full-time | Team: Product Engineering | Company: Argu

About Argu

Argu builds AI-powered products that solve real problems in production environments. We move fast, ship frequently, and care deeply about reliability, security, and clean execution. We’re looking for a senior fullstack engineer who is strong in Python backend development and strong in React frontend development, and who can own features end-to-end.

What You’ll Do

You will build and ship product features across the full stack, owning backend in Python to support operations at scale and frontend development equally.

Core Responsibilities

• Build and maintain backend services in Python + FastAPI (APIs, business logic, integrations, data flows).
• Design and implement clean, scalable REST APIs and service layers that power the product.
• Integrate R&D outputs (AI models, algorithms, internal services) into production through robust API layers and workflows.
• Build and maintain the frontend in React (component architecture, state management, hooks, performance).
• Own features end-to-end: requirements → backend design → API implementation → frontend integration → testing → deployment → monitoring.

What We’re Looking For (Must Have)

• 6+ years of experience building production systems as a fullstack engineer.
• Strong Python backend development, including production API design and service architecture.
• Proven ability to work with systems at scale
• Strong React experience is mandatory (modern React, hooks, component patterns, state management).
• Proven ability to ship complete features independently across backend and frontend.
•  Strong knowledge of relational databases (PostgreSQL preferred) and data modeling.
• Strong testing discipline (unit/integration tests), code review habits, and production ownership.
• Excellent communication and ability to work cross-functionally in a fast-paced environment.

Nice to Have

• TypeScript proficiency.
• Experience with Docker and CI/CD pipelines.
• Experience with cloud platforms (GCP/AWS).
• Experience with async Python and performance optimization.
• Experience with caching/queues (Redis, Celery, RabbitMQ, Kafka).
• Experience with observability tools (OpenTelemetry, Grafana/Prometheus, Sentry).
• Familiarity with ML/AI systems and integrating model-serving components into products.

Why Join Argu

• Backed by some of the world's leading investors, like Andreesen Horowitz and tier 1 VCs
• You will be a focal point in a category-defining product and company
• You'll work with some really smart people
• You should be a person we can have a beer with after work
