Founding Backend Engineer
 

This is the beating heart of wring.co. If this seat is empty:

• We can’t ship product at the speed early customers expect.
• There is no technical owner to set the bar for code quality, reliability, and velocity.
• We won’t have the foundation of a culture that values both rigorous engineering and pragmatic execution.
   

This role is the difference between a promising idea and a real business.
 

The Kind of Person We’re Not Looking For

Let’s be direct - if you:

• Need a lot of hand-holding before you start building.
• Prefer long planning cycles over quick iterations and learning by shipping.
• Feel uncomfortable making decisions with imperfect information.
• See your role as strictly “writing code,” not engaging with customers, recruiting, or thinking about the business.
• Clock in at 9 and out at 5 without caring whether the mission moves forward.
   

This isn’t going to be a fit. We want someone who:

• Thrives in ambiguity and moves fast.
• Spots problems and owns solutions end-to-end.
• Has a startup mindset: bias for action, curiosity, and a sense of urgency.
   

Core Responsibilities
 

Own the Backend Architecture

• Design, build, and maintain the APIs, data pipelines, and infrastructure.
• Make foundational decisions about how we scale and secure our systems.

Build and Lead the Engineering Team

• Recruit, onboard, and mentor the team.
• Define backend development standards and practices.

Collaborate Directly with Customers

• Join implementation calls, understand real-world workflows, and translate them into backend solutions.
   

Success Metrics
 

• Fast, Reliable Shipping
  • Consistently deliver backend features and improvements on aggressive timelines - without compromising stability.
• Clear, Usable Documentation
  • Create internal and customer-facing API docs that are always clear and up-to-date.
• Technical Ownership
  • The backend is stable, performant, and evolves rapidly - because you own it.
     

Our Stack (So Far)

• React (TypeScript) & Node.js (NestJS)
• PostgreSQL
• AWS 
   

This is not set in stone. You’ll have the mandate to evolve it.
 

Location & Flexibility

• We are based in South Germany.
• Hybrid or remote-friendly within CET ±3 hours.

Why Join Now?

• We’re seeing strong demand from 40+ customers
• Cloud cost optimization is a $10B+ problem waiting for better tools.
• You will shape both product and culture from day one.
   

What We Value

• Candor over politics.
• Bias for action over endless planning.
• Ownership over excuses.
   

Application Process

• We keep it simple:
  • Intro conversation.
  • Technical deep dive.
  • Paid trial project (optional) to ensure mutual fit.
