Full-Stack Developer (AI/LLM Focused)

About the Role

We're building an AI-powered platform — and we need a full-stack developer who can own features end-to-end. You'll work across a NestJS backend (pipelines, queues, LLM integrations) and a React frontend (data-heavy dashboards, multi-step workflows, role-based UI). 

Real impact — helping organizations assess and manage their portfolios’ reporting. 

What You'll Work On

• Design, Develop & Maintain Scalable Full-Stack Software
• Build robust features end-to-end using the PERN stack (PostgreSQL, Express.js, React.js, NestJS). Ensure clean architecture, reusable components, and maintainable code while delivering high-performance user experiences. 
• Backend: LLM integrations with extensive document processing, multi-stage pipelines, queue-based async job processing (BullMQ) with retry logic, REST APIs with Swagger docs and role-based access control. 
• Frontend: data-heavy dashboards, multi-step assessment workflows, multi-tenant architecture, permissions, multilingual UI. 
• Integrate & Optimize AI/LLM Services
• Incorporate LLM APIs (Anthropic Claude, OpenAI) into applications with structured tool use for scientific and document analysis. Design efficient request/response handling, optimize prompts, manage rate limits, and improve response quality and latency. 
• Document processing with LLMs — extract, parse, and analyze PDFs, Excel/CSV files, and images at scale as part of ESG workflows. 
• Collaborate with Cross-Functional Teams
• Work closely with product managers, designers, and other technical and non-technical team members  to translate requirements into technical solutions.  
• Maintain Security & Best Practices
• Implement secure coding practices, authentication/authorization, and data protection strategies. Ensure compliance with industry standards and best practices across the stack. 
• Troubleshoot, Debug & Improve Systems
• Identify and resolve issues across the full stack, monitor system performance (Sentry, Winston), and continuously enhance system stability and user experience. 

Required Skills

• Ts and Js  — strong proficiency across both backend and frontend 
• NestJS  — production API development, module architecture, guards, pipes 
• React  — hooks, component composition, custom hooks, React Query for all server state 
• PostgreSQL  — schema design, migrations, ORM + raw SQL when needed 
• Redis & BullMQ  — job queues, caching, async orchestration 
• REST API design  — DTOs, validation, error handling, Swagger documentation 
• Git  — clean commits, PR workflows 
• LLM integration & document processing  — hands-on experience calling LLM APIs (Anthropic, OpenAI), prompt engineering, and using LLMs for document parsing/analysis (PDF, Excel/CSV, images) 
• Strong English communication  — written and verbal; you'll collaborate across teams daily 
• Technical documentation  — experience writing clear architecture docs, system design decisions, and API documentation 

Nice to Have

• Azure Cloud services (Blob Storage, ACR, Communication Services) 
• Vector databases (Pinecone or similar) 

Ideal Candidate

• 5+ years building production full-stack applications 
• Has shipped features on a multi-role SaaS product before 
• Comfortable with dense, data-heavy interfaces and complex async pipelines 
• Reads existing code before writing new code — follows established patterns 
• Cares about simplicity, maintainability, and getting things right 

Education

• Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field. 

What Makes This Interesting

• Work at the intersection of AI, climate science, and finance 
• Complex multi-stage pipelines combining LLM analysis with scientific climate data 
• Shape the architecture as the platform scales
