Do you want to drive sustainability and make ESG reporting easier for businesses? 

TL;DR: North ESG is looking for an ambitious and dedicated Full-Stack Software Engineer to help build the future of ESG accounting for SMEs – AI-powered, fast-moving, and built for business impact.

About North ESG 

North ESG is the AI-powered ESG accounting platform for SMEs. 

For most SMEs, ESG reporting is a complex and time-consuming burden. We believe the future of ESG should be about growth - not admin. Our mission is to free up time while strengthening the ESG profile of SMEs, so they can stay competitive, win more business, and meet rising ESG demands. 

Our platform automates ESG reporting using AI – from data collection to emissions calculations and EU-aligned reports. It integrates with ERP systems and turns messy data into tailored, commercially viable ESG insights. 

We’re a product-led startup founded by ITU and DTU alumni with consulting backgrounds. With strong traction in Denmark and growing demand, we’re now scaling fast. 

What we’re looking for 

• You can be newly graduated or have several years of experience – mindset, curiosity, and ambition matter more than your CV 

• You care about shipping solid, scalable solutions – and you take pride in owning your work 

• You want to be part of an early-stage SaaS team solving real problems for real customers with proven product-market fit 

• You’re excited to grow with the company – including the opportunity to share in the venture’s success 

• You find inspiration in the intersection of sustainability, technology, and SMEs 

• You’re based in or near Copenhagen (or willing to relocate) 

What you’ll do:  

• Own and develop key parts of our platform – backend, frontend, and infrastructure 

• Design scalable systems and help shape our architecture from the ground up 

• Collaborate with our CPO, CTO and AI team to build high-impact features 

• Improve our DevOps pipelines, developer experience, and system performance 

• Contribute to product direction with a focus on usability, speed and reliability 

• Champion quality: write maintainable code, review pull requests, and share knowledge 

• Be a thought partner – not just an executor 

Our tech stack 

• Frontend:  React + Next.js 

• Backend:  PostgreSQL (Supabase) 

• AI:  RAG-LLM with embedded data in Pinecone 

• DevOps:  CI/CD with GitHub Actions, Docker, Azure 

• Project management:  GitHub Projects 

Experience with these technologies is a plus – but not a requirement. What matters most is your willingness to learn and grow. 

What we offer 

• Responsibility from day one – you’ll help shape architecture, functionality, and product direction 

• A strong, close-knit team – we’re currently four people working closely with a focus on collaboration, knowledge sharing, and a relaxed, informal atmosphere 

• Compensation & ownership – salary depending on experience, and we offer the opportunity for equity and co-ownership based on your profile and contribution 

• Flexibility – we offer remote work days but encourage in-person collaboration at our BLOXHUB office 

• A meaningful mission – we’re building a product that helps companies take climate action 

• Location – central Copenhagen, at BLOXHUB – Denmark’s leading community for sustainable construction and urban development 

About our team 

We’re a small, tight-knit, and social team that enjoys building things together – and having fun while doing it. We value collaboration, shared meals, team offsites, and good energy just as much as clean commits and scalable architecture. Here’s how we work: 

Drivers, not passengers – we take initiative and make it happen 

Ownership – we solve problems end-to-end 

Team over ego – we collaborate to win together 

Focused energy – we move fast and prioritize what matters 

Candor over comfort – we give honest feedback to grow better 

Details matter – because trust is built in the small things 

How we hire:  

1. Intro chat – a short conversation to align expectations and answer your questions 

2. Technical interview – we walk through some real problems (yours or ours) 

3. Team fit interview – you meet the team and we explore how we work together 

4. Offer – if there’s a match, we move fast
