Senior AI/LLM Engineer (Python) - Remote

Company: Kake

Senior AI/LLM Engineer (Python) - Remote
Kake is a remote-first company and a people-first global community of senior engineers. Kake engineers are behind some of the world’s most innovative products (Brands you’ve heard!), from Fortune 500 to fast-growing companies. We believe it’s not where your table is, but what you bring to the table that matters. Our community spans 45,000+ engineers across 55+ countries; join a culture where great people stay, grow, and thrive (and love eating kake!).
Senior AI/LLM Engineers with strong Python experience, skilled in designing, building, and productionizing LLM-powered applications and AI systems at scale. It's a great fit for people who enjoy working at the intersection of software engineering and applied AI, and who take ownership from prototyping through production deployment.
What you’ll build and own
* Design, build, and deploy LLM-powered features and applications using Python.
* Develop and maintain backend services and APIs (e.g., FastAPI) that expose AI/LLM capabilities to other systems.
* Build and optimize RAG pipelines, including embeddings, vector search, and retrieval strategies.
* Design, test, and iterate on prompts, agents, and orchestration flows using frameworks such as LangChain, LlamaIndex, or similar.
* Integrate with LLM providers and APIs (e.g., OpenAI, Anthropic, open-source models) and manage tradeoffs around cost, latency, and quality.
* Evaluate model outputs systematically, building tooling and metrics to test accuracy, safety, and regression across iterations.
* Work with containerized environments and data infrastructure (e.g., PostgreSQL, Redis, vector databases) to support reliable AI systems in production.
* Collaborate with cross-functional stakeholders to translate ambiguous product needs into technically sound AI solutions.
Core Requirements
* Strong proficiency in Python and experience with FastAPI or similar backend frameworks.
* Experience working with LLM APIs (e.g., OpenAI, Anthropic, or similar) and frameworks such as LangChain or LlamaIndex.
* Experience with RAG architectures, embeddings, and vector databases (e.g., Pinecone, Weaviate, pgvector, or similar).
* Hands-on experience with Docker and containerized development environments.
* Experience working with PostgreSQL, Redis, or similar data stores.
* Strong experience writing functional and integration tests, including evaluation frameworks for AI/LLM output quality.
* Excellent written and verbal communication skills in English.
* Ability to work independently in a remote, fast-paced environment.
Nice-to-Have
* Experience fine-tuning or evaluating open-source LLMs.
* Familiarity with prompt engineering best practices and agentic workflows.
* Experience with distributed systems, streaming (e.g., Kafka), or large-scale applications.
* Background in machine learning fundamentals (e.g., scikit-learn, PyTorch, or TensorFlow).
* Comfortable working flexible hours to overlap with distributed teams across different time zones.
Additional
* US Timezone Overlap: 5h–6h daily PST
