Full-Stack Developer (AI/LLM Focused)

Job description

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, Deve...lop & 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
