Engineering Manager - Product Engineering (Climate Tech)

Engineering Leadership & Hands-on Work (~50%)

• Build and evolve CCF and emission reduction features with a strong focus on correctness, auditability, and performance.
• Work on data-intensive systems: ETL pipelines, transactional → analytical data flows, and real-time carbon analytics.
• Design and operate AI-assisted workflows (including self-hosted LLMs) to process large amounts of supplier and emissions data efficiently and reliably.
• Review code across Go, Ruby on Rails, and Vue.js, keeping systems stable as complexity grows.

Team, Hiring & Coaching (~30%)

• Hire engineers with strong technical fundamentals and a product mindset.
• Coach the team through architectural change (monolith → services, data & AI-first thinking).
• Foster ownership, pragmatism, and a culture focused on solving customer problems - not just shipping tickets.

Architecture & Technical Direction (~20%)

• Partner closely with Product and the CTO to align product goals and technical decisions.
• Decide what stays in the monolith and what moves into dedicated services.
• Shape our data and AI architecture, balancing deterministic logic with LLM-based approaches and ensuring end-to-end data integrity.

This role helps large enterprises measure and reduce their Scope 3 (supply chain) emissions - the most complex and impactful part of corporate decarbonization, directly contributing to climate change mitigation through scientifically accurate carbon calculations.

• 8+ years in software engineering, including 2+ years in a leadership or management role.
• Proven player-coach experience: staying hands-on while leading a senior team.
• Experience evolving large systems (e.g. monolith to services) without breaking production.
• Strong background in data-heavy systems (ETL/ELT, OLTP ↔ OLAP, analytics workloads) and expertise working with Big Data.
• Practical experience designing and operating AI or LLM-based systems in production.
• Based in CET ±1 hour for sufficient team overlap. Valid EU/EEA work authorization.
• Strong Ruby on Rails experience and solid proficiency in Go.
• Good understanding of PostgreSQL performance and data modeling.
• Experience with modern frontend frameworks (Vue.js 3 or similar).
• Solid foundation with containerized infrastructure (Docker/Kubernetes).
• Experience building software with high correctness and auditability requirements (e.g. climate, fintech, ERP).
• Proven ability to hire, mentor, and grow senior engineers in an ego-less manner.
• Great reflection skills
• Comfortable working in a fully remote, asynchronous-first environment.
• Clear, structured communication in English.

• Competitive compensation + VSOP option
• 28 vacation days + flexible planning
• 100% remote, flexible working hours - family-friendly
• Annual team offsites
• Freedom to contribute to the open source community

Global Changer helps large enterprises measure and reduce their Scope 3 (supply chain) emissions through their CCF (Corporate Carbon Footprint) platform, which provides scientifically accurate, auditable carbon calculations across millions of supplier data points to drive corporate decarbonization.
