## Job Description  
**Software Engineer** at **BlueLayer** (Berlin, Germany, Hybrid).  
*Is this the most important century in human history?*  
The climate crisis is no longer abstract. Businesses, governments, and consumers are acting—cutting emissions and buying carbon credits to offset what they can't yet eliminate. To meet projected needs, global carbon credit supply must increase by up to 4,000% in the coming years. Yet most project developers lack the infrastructure to scale credibly.  

**About BlueLayer**  
BlueLayer builds the software infrastructure that enables high-quality carbon credit supply to scale. We give carbon project developers tools to automate MRV, inventory, and core workflows, so credible supply can reach the market efficiently and transparently. BlueLayer is mission-driven and committed to diversity and inclusion.  

**Responsibilities**  
- Contribute to the whole development cycle (architecture design to implementation, testing, maintenance).  
- Prototype and iterate until solutions are impactful and polished.  
- Take ownership of improving engineering practices, managing technical debt, and ensuring high code quality.  
- Support the team with internal tooling, CI/CD infrastructure, data pipelines, and testing infrastructure.  
- Engage directly with users and shape the future of BlueLayer’s technology and product.  

**What You Bring**  
- Full-stack software engineering experience in B2B SaaS environments.  
- Proficiency in **React.js** and **Node.js**.  
- DevOps mindset with CI/CD pipeline experience.  
- Excellent communication skills in English.  
- Customer-focused approach and pragmatic problem-solving.  
- BSc/MSc in Computer Science, Engineering, or equivalent.  

## Company Intelligence  
- **Industry**: Software Development  
- **Size**: 11–50 employees  
- **Location**: Berlin, Germany (operates in Berlin, Athens, London)  
- **Mission**: Enable high-quality carbon credit supply through software tools for project developers.  
- **Culture**: Mission-driven, values diversity/inclusion, ownership, clarity, and impact. Remote-friendly with equity for team members.

- **Mission Alignment**: Strong cultural fit with BlueLayer’s climate-driven mission.  
- **Seniority Credibility**: Leadership indicators (Zeitner GmbH solo backend architect) and ownership of production systems.  

**Risks**:  
- **Future Employment Date Discrepancy**: Current role listed as Jan 2025–Present (inaccurate for 2023 timeline).  
- **Missing B2B SaaS Specifics**: Job description emphasizes B2B SaaS but resume lacks explicit examples.  
- **No Salary Expectations**: Salary goal provided but not reflected in resume.  

**Recommendations**:  
- Fix employment date discrepancy (current role started in 2023, not 2025).  
- Add B2B SaaS project examples with metrics (e.g., Yoobux’s 30% throughput improvement).  
- Include salary expectations in resume header (e.g., "Target: €65k–€75k").  
- Optimize skills section for ATS with "B2B SaaS" and "climate tech" keywords.
