The Opportunity

We are seeking a Full-Stack Developer with strong DevOps and AI integration skills to build, deploy, and secure end-to-end applications for banking clients. This role requires expertise in modern web development, containerization, on-premises Docker environments, secure infrastructure (e.g., HashiCorp Vault), and AI/LLM-based architectures (including RAG pipelines). The ideal candidate will have hands-on technical expertise, strong security awareness, and the ability to communicate complex solutions to clients.

Key Responsibilities

Infrastructure & Server Setup

• Prepare hardware and configure Linux-based and Windows-based on-prem servers (small to medium complexity)
• Install, configure, and run Docker in on-premises environments, including Docker Compose for multi-service setups
• Deploy and configure Apache/Nginx within containerized environments

Security & Secrets Management

• Deploy and configure HashiCorp Vault on premises (medium to large complexity)
• Set up secrets and certificates, enable encryption, and configure secure access
• Ensure client applications can securely pull secrets from Vault

AI/LLM Integration

• Set up LLM environments (low to medium complexity)
• Build knowledge bases using vector databases (Postgres, Weaviate, or similar)
• Implement document ingestion pipelines (document parsing, chunking, embeddings generation, and storage)

RAG (Retrieval-Augmented Generation) Orchestration

• Develop inference pipelines using LangChain or n8n
• Implement retrieval, augmentation, and generation workflows
• Create API contracts for frontend-backend integration

Backend & API Development

• Initialize and build Python/FastAPI projects
• Expose RAG pipeline endpoints through secure REST APIs

Frontend Development

• Create React SPA applications with chat-like UIs (ChatGPT-style interfaces)
• Integrate frontend with backend APIs based on defined contracts

Deployment & Routing

• Configure Apache/Nginx reverse proxy rules for routing frontend and backend traffic

Client Interaction

• Present technical solutions, architecture diagrams, and deployment strategies to clients
• Translate complex technical concepts into clear, non-technical language
• Collaborate with stakeholders to align solutions with business and security requirements

Required Skills & Qualifications

Technical Expertise

• Strong experience with Docker (on-premises), Linux server administration, and container orchestration
• Hands-on experience with HashiCorp Vault (secrets engines, policies, and client integrations)
• Proficiency in Python (FastAPI, Flask) and React.js
• Understanding of vector databases (Weaviate, Pinecone, or Chroma) and RAG pipelines
• Familiarity with LangChain or workflow automation tools like n8n
• Web servers: Nginx/Apache reverse proxy and SSL/TLS configuration
• Knowledge of document parsing (PDF, CSV, text) and embedding models (OpenAI, Hugging Face)

Security Awareness

• Strong understanding of data security, encryption, and certificate management
• Awareness of banking security standards (e.g., SOC2, PCI-DSS basics)
• Ability to design and review secure APIs and infrastructure

Soft Skills

• Excellent presentation skills for client demos and solution walkthroughs
• Ability to document and explain technical architectures clearly
• Collaborative mindset for cross-functional teamwork

Nice-to-Have Skills

• Exposure to GPU-based LLM hosting (e.g., Hugging Face models)
• Familiarity with cloud services (AWS, GCP, Azure) and hybrid on-prem/cloud setups
