Design Advanced AI Architectures 

• Design and implement Retrieval-Augmented Generation (RAG) systems using vector databases 

• Build and orchestrate AI agents using frameworks such as LangGraph, CrewAI, or similar 

• Evaluate and select appropriate large language models (LLMs) and foundation models based on specific use cases 

Optimize Performance and Scalability 

• Continuously optimize model inference for latency, cost efficiency, and throughput at scale 

• Identify bottlenecks and implement improvements to ensure high-performing systems 

Ensure Reliability and Observability 

• Implement robust monitoring, logging, and alerting for deployed models and services 

• Ensure system reliability, uptime, and performance through best practices in production ML systems 

Establish Engineering Best Practices 

• Build and maintain CI/CD pipelines for seamless testing, deployment, and iteration of AI systems 

• Contribute to evolving engineering standards as the company transitions from rapid experimentation to more structured, scalable operations 

Collaborate Cross-Functionally 

• Work closely with product and engineering teams to integrate AI capabilities into core products 

• Translate business problems into technical solutions and clearly communicate trade-offs 

Drive Structure in a Fast-Paced Environment 

• Help bring stability and structure to AI development processes during a high-growth, scale-up phase 

• Balance speed of execution with the need for maintainable, well-documented, and scalable systems 

• Take ownership of ambiguous problems and drive them through to practical, production-ready outcomes 

Core Experience 

• 5+ years of experience in Python, with ~10 years of overall software engineering or data experience (candidates transitioning from backend engineering are welcome) 

• Proven experience building and deploying production-grade APIs (preferably with FastAPI; REST/GraphQL experience is a plus) 

• Hands-on experience working with large language models (LLMs) and LLMOps, including prompt engineering, fine-tuning, and evaluation (e.g., GPT, Claude) 

• Strong experience fine-tuning open-source models (e.g., Hugging Face ecosystem) 

• Practical experience designing and working with vector databases (e.g., Pinecone, Weaviate, Chroma, pgvector) 

• Experience building AI agents using frameworks such as LangGraph, LangChain, CrewAI, or similar 

• Solid understanding of model deployment and serving (e.g., vLLM, TGI, or managed endpoints) 

• Experience with CI/CD pipelines and modern deployment practices (Docker, Kubernetes, GitHub Actions) 

• Strong experience working with and processing large-scale text datasets 

Preferred Experience 

• Experience with MLOps platforms such as MLflow or Weights & Biases 

• Familiarity with cloud AI ecosystems (e.g., AWS Bedrock, GCP Vertex AI, Azure OpenAI) 

• Contributions to open-source AI/ML projects 

• Experience in the sustainability or climate/product domain 

• Background in B2B SaaS environments 

• Prior experience in a startup or scale-up environment (approximately 100–300 employees)
