Full Stack Developer - B2B SaaS (m/f/d)

Our Mission

Rethinking returns – shifting them from a cost factor to a strategic lever for customer satisfaction, efficiency, and sustainability.

toern is a data-driven B2B SaaS solution for e-commerce, automating returns and exchange processes while enabling data-backed decisions through AI-powered analytics.

Tasks

• Full Stack Development: You’ll build new features in both the frontend (React) and backend (Node.js/AWS) – from idea to rollout.
• Close Collaboration: Work directly with the founder and dev team, actively shaping architecture, product, and internal processes.
• System Ownership: You identify bugs, track down root causes, and fix them properly – no quick fixes, but sustainable solutions.
• Cloud Infrastructure: Together with the founder, you’ll manage our AWS-based infrastructure (Lambda, Step Functions, RDS).
• Hands-on & Versatile: You’ll jump in wherever needed – whether it’s onboarding new customers, performance tuning, or feature development.

Requirements

• Degree in Computer Science or equivalent qualification.
• 2+ years of experience in software development and building/operating web-based software solutions.
• Comfortable with Node.js, React, relational databases, and distributed systems (AWS or similar).
• You want to build, not just maintain – you love creating from scratch and taking ownership.
• You work independently, think ahead, and actively look for pragmatic solutions – even when requirements are unclear or evolving.
• Strong communicator and team player – unafraid to speak up and take responsibility.
• Nice to have: Experience in e-commerce, B2B SaaS, returns/logistics, Postgres, or dynamic infra setups.

Benefits

• Ownership from Day 1: Work directly with the founding team and take real responsibility.
• A team of equals: Motivated, flat-hierarchy team that doesn’t just talk about better return processes – we build them.
• Tangible impact: Your work will directly shape the growth and evolution of toern.
• Steep learning curve: Expect fast professional and personal development.
• Flexible work setup: Co-working space in Hamburg + remote option + flexible hours.
