The posting

Full-Stack Developer – Next.js & Python

Position Type: Full-Time, Remote

Working Hours: U.S Business Hours

About the Role

We are looking for an experienced Full-Stack Developer to build and maintain production web applications across a modern frontend, backend, database, and cloud stack.

This is a hands-on development role for someone who can own a slice of the product across both UI and API. You’ll work with Next.js, React, TypeScript, Python, FastAPI, relational and graph databases, multi-service architecture, real-time functionality, and Azure infrastructure.

What You’ll Own

Frontend Development

  • Build production web applications using Next.js 16 with App Router, React 19, and strict TypeScript.
  • Work with server/client boundaries and data-fetching using TanStack Query or equivalent.
  • Build interfaces using Tailwind CSS v4, shadcn/ui + Radix, Zustand, React Hook Form + Zod, and AG Grid Enterprise.
  • Work with Framer Motion and Socket.IO.
  • Write frontend tests using Vitest + Testing Library.
  • Build end-to-end tests using Playwright.

Backend Development

  • Build and maintain backend services using Python 3.13 and FastAPI.
  • Work with Pydantic v2, SQLAlchemy 2 / SQLModel, Alembic, Celery, Redis, and uv.
  • Work with typed schemas, async I/O, authentication, and background jobs.
  • Work within a multi-service codebase using HTTP between services, Redis, and workers.

Database & Data

  • Work with relational modeling and migrations using SQLAlchemy/Alembic or equivalent.
  • Work with Azure SQL (MSSQL) and PostgreSQL.
  • Work with Neo4j for family / heirship graphs.
  • Work with PostgreSQL + pgvector.
  • Work with MongoDB for logs.

Cloud & Operations

  • Work with Azure services including Blob, Identity, Key Vault, SQL, and Container Registry.
  • Work with Docker Compose.
  • Work with Prometheus / Grafana.
  • Work with pnpm workspaces + Turborepo.

Advanced Features & Integrations

  • Work with graph databases or non-trivial graph UIs such as trees, canvases, XYFlow/D3/canvas.
  • Work with complex data UIs including AG Grid, maps, PDF viewers, and rich text using Tiptap.
  • Work with real-time technologies such as Socket.IO / WebRTC or telephony platforms such as Telnyx or similar.
  • Work with LLM/RAG features including embeddings, pgvector, and tool-using assistants.
  • Work with chatbot services; you do not need to be an ML engineer.

Required Experience & Skills

  • 6+ years shipping production web apps.
  • 3+ years as the person who owns a slice across UI and API.
  • Strong TypeScript and React experience.
  • Comfortable with App Router, server/client boundaries, and data-fetching using TanStack Query or equivalent.
  • Strong Python and FastAPI experience, or Django/Flask at a similar depth.
  • Experience with typed schemas, async I/O, authentication, and background jobs.
  • Strong relational modeling and migration experience using SQLAlchemy/Alembic or equivalent.
  • Experience with MSSQL or PostgreSQL.
  • Experience in a multi-service codebase with HTTP between services, Redis, and workers, not only a single monolith.
  • Tests as a habit: unit/integration on the backend and component tests on the frontend.
  • Clear written communication.
  • Ability to leave the next engineer a module they can change without a walkthrough.

Strongly Preferred

  • Graph databases such as Neo4j or non-trivial graph UI using trees, canvases, XYFlow/D3/canvas.
  • Azure experience with SQL, Blob, Key Vault, or a comparable cloud.
  • Experience with complex data UIs such as AG Grid, maps, PDF viewers, or rich text using Tiptap.
  • Real-time experience with Socket.IO / WebRTC or telephony with Telnyx or similar.
  • LLM/RAG experience including embeddings, pgvector, and tool-using assistants.

Nice-to-Haves We Actually Use

  • WebRTC calling.
  • DocuSign / PKCS#7 signing.
  • GEDCOM.
  • Google Maps.
  • Campaign/inbox graph models.
  • Prometheus metrics.

What Makes You a Strong Fit

  • You have extensive experience shipping production web applications and owning a slice across both UI and API.
  • You’re comfortable working across TypeScript/React and Python/FastAPI.
  • You can confidently reason about relational modeling, migrations, and multi-service architecture.
  • You’re comfortable working with Redis, workers, and HTTP communication between services.
  • You treat testing as part of development rather than something to add later.
  • You communicate clearly in writing.
  • You leave the next engineer with a module they can change without a walkthrough.

What Success Looks Like

  • You can independently own a slice of the product across UI and API.
  • Production features are supported by appropriate backend and frontend tests.
  • Relational models and migrations are reliable and maintainable.
  • Multi-service communication, Redis, and workers operate effectively.
  • Complex data UIs and graph-based functionality are implemented effectively where required.
  • Real-time, cloud, and third-party integrations work reliably.
  • Your code is clear enough for the next engineer to understand and modify without a walkthrough.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
