About The Position

We're looking for a Full-Stack Software Engineer to join early. Someone who’s eager to learn, ready to contribute, and excited to work on real systems alongside experienced engineers. You’ll touch every layer of the stack — from UI components, API endpoints, deployment pipelines, and AI-based workflows — and play a critical role in shipping features, fixing bugs, and helping the team move fast without breaking things.

Requirements

2–5 years of professional software engineering experience (startup or fast-paced environment a plus)
Comfortable working across both frontend and backend, even if you lean one way
Experience with modern frontend JS frameworks (React, Vue, etc.)
Experience with async Python frameworks (FastAPI, Sanic, Starlette)
A desire to write clean code, ask good questions, and keep getting better
Team player mindset — curious, proactive, and humble
Confident English skills to collaborate clearly and effectively with teammates

Nice To Haves

Have shipped features that spanned frontend + backend
Have worked in an event-driven or microservice architecture
Are familiar with Python, Postgres, or TypeScript
Have side projects or open-source work you’re proud of

Responsibilities

Build features across the stack: React UI, Python APIs, agentic workflows, MCP server integrations, database models, and everything in between
Pair with senior engineers to implement scoped tickets and stretch into bigger ones
Write testable, maintainable code that fits into the broader architecture
Participate in planning, code review, and strategy — we’re a tight team, everyone has a voice
Learn rapidly by doing, and contribute ideas as you grow
