Senior Backend-Focused Full Stack Developer – Python / FastAPI

Overview

We’re looking for a Senior Full Stack Developer (Backend Heavy) to lead the design and development of complex, operations-heavy internal platforms — such as CRMs, Inventory Systems, and Vendor Management Tools.
If you’re strong in backend architecture, Python/FastAPI ecosystems, and asynchronous task orchestration (Celery or Dramatiq) — and can guide a small engineering team f — we’d love to connect.

Key Responsibilities
Translate business operations into modular, maintainable backend workflows
Architect and build scalable, extensible internal applications and APIs
Design and implement robust backend logic using FastAPI, SQLModel/Pydantic, and task queues (Celery/Dramatiq)
Oversee API integrations, background job orchestration, and workflow automation
Lead a small engineering team, enforcing clean architecture, code quality, and delivery standards
Collaborate with UX and frontend teams (React/Next.js) for seamless integration
Own the full lifecycle: requirements → architecture → implementation → QA → deployment → maintenance

Requirements
Strong background in Python backend development (FastAPI preferred)
5+ years of full stack experience with emphasis on backend architecture and workflows
Hands-on experience withFastAPI, Pydantic, SQLAlchemy, Celery/Dramatiq, and task-based architecture
Solid understanding of database design, optimization, and migrations
Experience building modular service layers and integrating third-party APIs
Adept in DevOps, CI/CD pipelines, and cloud deployments (AWS, GCP, or Railway)
Frontend familiarity — enough to guide React/Next.js developers and review PRs
Excellent leadership, estimation, and communication skills — comfortable mentoring and unblocking other devs

Bonus: Experience with Dramatiq and knowledge of refine.dev framework

Preferred Stack
Backend: Python, FastAPI, SQLAlchemy, Pydantic, Celery/Dramatiq
Frontend: React, Next.js
Database: PostgreSQL
Infra: Docker, AWS, Railway, CI/CD pipelines

To Apply
Please share:
Links or descriptions of internal tools/platforms you’ve architected or led
Examples of backend-heavy projects where you designed core workflows or async systems
Any relevant GitHub, portfolio, or case studies showcasing your Python/FastAPI expertise
