Backend Engineer - saas.group

This role is part of our 3D AI Studio team, one of our growing brands at saas.group.

3D AI Studio is an AI platform that turns images and text into ready-to-use 3D models in minutes, work that traditionally takes a 3D artist days or weeks. Game developers, 3D printing enthusiasts, and creators use the platform to generate and edit images, turn them into 3D models in every major format, and chain it all together into their own pipelines. With more than 2 million registered users, we are now expanding into the business space, building custom AI workflows for companies such as 3D printing businesses.

Profile Overview

We’re looking for a Backend Engineer to take full ownership of our Django backend and production infrastructure. You’ll work directly with our founder to review and improve code, build backend features, and keep the platform stable, secure, and fast for a large and growing global user base.

This is a role with real ownership: the backend and the server are yours, and you’ll have the autonomy to decide how to make them better. You won’t start from zero either: you’ll work alongside the engineer who currently looks after our backend while you get up to speed. The role is fully remote, with working hours aligned to Central European Time.

Immediate Impact (First 3–6 Months)

• Get to know our backend and server inside out, working alongside our current backend engineer, and take over full ownership.
• Review and improve our existing Python/Django code and start shipping new backend features.
• Help migrate our PostgreSQL database to Neon.
• Make sure background jobs, external API integrations, monitoring, and backups run reliably.

Responsibilities

• Backend Ownership: Review, improve, and develop Python/Django code, building new backend features together with the founder.
• Infrastructure Management: Manage our Hetzner Linux server, deployments, software updates, and server security.
• Performance & Reliability: Investigate backend issues, resolve incidents, and optimize performance so the platform stays stable, secure, and fast.
• Database Administration: Maintain our PostgreSQL database and help migrate it to Neon.
• System Maintenance: Keep background jobs, external API integrations, monitoring, and backups reliable.
• AI Tooling: Use AI coding tools daily to move fast without compromising quality.

Requirements

• Python & Django: Strong production experience building and maintaining backends with Python and Django.
• Databases: Good PostgreSQL / SQL skills, including query optimization and migrations.
• Linux & Infrastructure: Hands-on Linux server administration and production troubleshooting.
• Backend Architecture: Experience with REST APIs, background jobs, and task queues such as Celery / RabbitMQ.
• Engineering Practices: Comfortable with Git, code reviews, testing, and safe deployments.
• Ownership & Communication: Independent, reliable, self-directed, and able to communicate technical issues clearly.
• AI Literacy & Application: Actively use AI tools to enhance personal productivity and work quality, staying curious about emerging capabilities.

Bonus Points

• Experience with Hetzner, Neon, Nginx, S3-compatible storage, or CI/CD pipelines.
• Basic familiarity with 3D models and simple 3D workflows (no advanced 3D expertise required).
• Experience with AI APIs or media processing.

What We Offer

• Ultimate Flexibility: 100% remote work environment.
• Freedom & Autonomy: High-trust culture with ownership over your work.
• Minimal Bureaucracy: Streamlined processes with steady and sustainable momentum.
