- **Location:** Berlin, Germany
- **Employment:** full-time
- **Work type:** hybrid
- **Posted:** 2025-07-30
- **Last confirmed live:** 2026-09-04

## Job description

At 8returns, we’re transforming one of the most frustrating, environmentally damaging, and costly aspects of e-commerce: returns.

Trusted by the fastest-growing DTC names like OACE, PEGADOR, GOT BAG, and now adopted by iconic brands such as Fielmann, Tommy Hilfiger, and Reebok, we’re inventing what’s next in post-purchase.

As a Backend Software Engineer at 8returns, you’ll own the systems that make our product fast, reliable, and scalable. From APIs to data models to integrations, you’ll build the foundation that turns returns chaos into margin protection. If you care about clean architecture, love shipping, and want real ownership, this is your role.

## TASKS

- Ship new backend features with Rails and PostgreSQL
- Design and maintain APIs that power our frontend and external integrations
- Improve performance, reliability, and developer experience across the stack
- Own core data models and workflows that merchants rely on daily
- Debug and fix issues quickly, but always aim to build long-term solutions
- Explore ways to integrate AI/automation to make systems smarter and faster
- Work closely with founders and PM to prioritize what matters most

## REQUIREMENTS

- 3+ years building production web apps with Rails
- Strong database skills (PostgreSQL, schema design, query optimization)
- Solid understanding of backend architecture and API design
- You’re pragmatic — you solve problems, not just write code
- Comfortable with ambiguity and tradeoffs; you keep moving
- Autonomous. We give you problems, not solutions

## BONUS POINTS IF:

- You’ve worked in an early-stage SaaS startup or as a founder
- You know your way around Heroku / AWS / infrastructure basics
- You’ve dabbled in AI/LLMs (OpenAI, Claude, LangChain, etc.)
- You can jump into React/TypeScript when needed

## BENEFITS:

- Direct impact on millions of users
- Own what you build, no layers of approval
- Low-meetings, high-ownership culture
- Work directly with the founders
- Berlin-based, flexible hybrid setup
- Meaningful equity in a profitable, fast-growing company

We run lean, stay profitable, and care about solving real merchant problems.

- **Early team impact**: Join as an early member and shape the direction of the company, with wide ownership and exposure to all parts of the business.
- **Small, agile team**: 9 people across Germany, Tunisia, and India; technical team is ~18% of headcount; flat hierarchy with direct access to founders.
- **Culture**: Values comfort with ambiguity, wide impact, and making the journey rewarding — "otherwise it's not worth it."
