Senior Backend Engineer
Eden AI
Overview
At Eden AI, we simplify access to the best AI providers through one unified API. From LLMs and OCR to speech-to-text and computer vision, we aggregate services from hyperscalers (AWS, GCP, Azure) and specialized vendors (Cohere, Anthropic, AssemblyAI, Mistral, and more). Thousands of developers and companies rely on our platform to power production-grade AI workflows with performance, flexibility, and transparency. We also build custom AI APIs tailored to client needs - complete with confidence scoring, real-time monitoring, evaluation pipelines, and full observability. We're looking for a Senior Backend Engineer who loves building high-performance, scalable APIs and developer tools. You'll own core backend systems that power our API platform, handling high request volumes, multi-tenant data flows, and real-time AI workloads. You'll work across our stack - from FastAPI and Django to AWS infrastructure - helping us design robust, observable, and maintainable systems that keep our AI services fast, secure, and reliable.
What you will do
- Architect and maintain backend services handling thousands of API calls per minute
- Build and optimize async-first Python APIs (FastAPI, asyncio, aiohttp) for speed and scalability
- Design and maintain developer-focused APIs and SDKs used by hundreds of companies
- Optimize database performance, caching, and rate limiting across our multi-tenant platform
- Manage infrastructure on AWS (ECS, Lambda, S3, CloudWatch, etc.)
- Collaborate with the AI team to integrate new models and data pipelines efficiently
- Implement observability: logging, metrics, tracing, and error handling that scale
Requirements
- 6+ years of backend engineering experience, preferably in Python
- Strong command of FastAPI, Django, or similar frameworks
- Experience with asynchronous Python (asyncio, aiohttp, background tasks)
- Solid understanding of AWS services and cloud-native architectures
- Familiarity with API design, RESTful standards, and developer experience best practices
- Knowledge of PostgreSQL, Redis, Celery, and task orchestration systems
- Obsessed with performance, reliability, and code clarity
- Bonus: experience with observability tools (Prometheus, OpenTelemetry, Sentry) or API gateways
Benefits & conditions
- Work on high-performance backend systems powering real AI products
- Collaborate with a senior, pragmatic team that ships fast and avoids bureaucracy
- Build developer tools and APIs used daily by engineers worldwide
- Competitive salary and meaningful impact from day one
- Fully remote or hybrid
