Description

About the Role We’re looking for a Full Stack Developer with deep expertise in AI-driven architectures, agentic systems, and cloud-native development. You’ll build intelligent, scalable web applications and contribute to cutting-edge AI workflows — from orchestration and retrieval to vector-based search and human-in-the-loop pipelines. This role combines traditional full stack engineering with modern AI system design and cloud infrastructure management, ensuring our AI applications are performant, secure, and production-ready. Key Responsibilities🧠 AI & Agentic Systems Development Design and build multi-step agentic systems using LangGraph (preferred) or LangChain graphs. Implement planning/orchestration logic, tool usage, retries/timeouts, guardrails, and agent memory (short-term, episodic, semantic, and vector). Build human-in-the-loop features, including review/approval gates, correction loops, escalation paths, and audit trails. Develop and optimize Advanced RAG pipelines: Chunking strategies Hybrid search (BM25 + vector) Parent-child / graph RAG Query rewriting & reranking Grounding with citations, hallucination control, and evaluation workflows. Work with vector databases (pgvector, Qdrant, Milvus, Weaviate, Pinecone) and understand HNSW/IVF parameters, recall/latency tradeoffs, sharding, compaction, and embeddings versioning/caching. 💻 Full Stack Development Design and implement front-end (React, Next.js, or similar) and back-end (Node.js, Python/FastAPI, or similar) applications. Build scalable APIs and integrate with AI pipelines and microservices. Ensure performance, security, and maintainability through clean architecture, testing, and CI/CD pipelines. Collaborate cross-functionally with product, design, and ML teams. ☁️ Cloud Engineering & Infrastructure Develop, deploy, and maintain applications in cloud environments (AWS, GCP, or Azure). Use cloud-native tools and services for containerization, orchestration, and monitoring. Design scalable, fault-tolerant architectures supporting AI workloads and vector database deployments. Manage networking, storage, and security configurations aligned with best practices. Optimize performance and cost efficiency in multi-environment setups (dev/staging/prod). Required Skills & Qualifications Bachelor’s degree in Computer Science, Engineering, or related field (or equivalent experience). 4+ years of experience as a Full Stack Developer working across front-end and back-end technologies. Proven hands-on experience with cloud platforms (AWS, GCP, or Azure). Strong proficiency in JavaScript/TypeScript, Python, and modern frameworks. Experience in building or integrating AI/LLM-powered systems and agentic workflows. Familiarity with LangGraph or LangChain. Deep understanding of vector databases and RAG systems. Strong grasp of distributed systems, data flow, and security fundamentals. Nice-to-Have Experience with infrastructure as code (Terraform, CloudFormation, or Pulumi). Exposure to Kubernetes, serverless, and container orchestration. Experience fine-tuning or evaluating LLMs and open-weight models. Familiarity with monitoring/observability (Prometheus, Grafana, OpenTelemetry). Contributions to open-source AI or cloud projects.
