Senior Full-Stack Engineer

At Symphonize, we build real, production-grade systems across multiple industries—and we’re growing our team in Ann Arbor, Michigan.

We’re looking for a Senior Full-Stack Engineer who enjoys building software end-to-end and wants to work on a mix of SaaS platforms, cloud-native applications, and AI-enabled systems, including contributions to our evolving Agentic AI platform.

This is a hands-on engineering role, not a people-management position.

What you’ll work on

Build and ship full-stack production applications

Backend development using Python (FastAPI, Django, or Flask)

Frontend development with JavaScript / TypeScript

Design and deploy AWS-based cloud-native systems

Work with SQL and NoSQL databases

Collaborate on AI-powered features (search, retrieval, automation)

Participate in architecture decisions and technical discussions

Collaborate closely with internal teams and occasionally with clients

What we’re looking for

10 to 15 years of experience delivering production software

Solid backend experience with Python

Working knowledge of JavaScript / TypeScript

Hands-on experience with AWS

Comfort working across backend, frontend, and infrastructure

Clear communicator and collaborative team player

Willing to work onsite in Ann Arbor, with some hybrid flexibility

Visa sponsorship is not available for this position

Nice to have (not required)

Exposure to AI / LLM-based systems or RAG-style architectures

Experience with Docker, serverless, or SaaS platforms

Curiosity and interest in working on Agentic AI workflows

Why Symphonize

Real ownership and hands-on engineering

Opportunity to work on AI-powered platforms without needing an AI research background

Variety of projects across industries

A pragmatic culture that values quality, speed, and good judgment
