Why this grade This listing scored 42/100, which is a D. It lost the most ground on freshness. See the breakdown
- Description depth 20 / 20 How much the posting actually says about the work, measured in characters of real text.
- Remote clarity 15 / 15 Whether "remote" means anywhere, or is quietly restricted to one country.
- Pay transparency 12 / 25 A published salary range, worth more than any other single factor because it is what a candidate cannot find out without applying.
- Corroboration 10 / 10 Whether more than one source carries this listing.
- Role specificity 0 / 10 Whether the listing is tagged well enough to tell what the role actually is.
- Freshness 0 / 15 How recently it was posted. Older postings are likelier to be filled or abandoned.
-15 Ghost-job penalty — Deducted for signals that this posting may not be a real, currently-open role — staleness, repeated relisting, or talent-pool language.

- Retrieval-Augmented Generation (RAG) pipeline design.
- Experience with vector databases (Pinecone, Weaviate, Milvus, Chroma, FAISS).
- Hands-on with LLMs & APIs: OpenAI (GPT-5/5-mini), Anthropic Claude, Google Gemini, Meta Llama, Mistral.
- Familiarity with AWS Bedrock for accessing and deploying foundation models.
- Prompt engineering and structured output design (JSON mode, function calling).
- Model fine-tuning (LoRA, QLoRA) and evaluation frameworks (DeepEval, Ragas).
Responsibilities:
- Design and develop backend systems and APIs for AI-powered applications.
- Build and optimize LLM-based workflows, including chatbots, copilots, and automation tools.
- Implement RAG architectures using vector databases and document pipelines.
- Integrate and orchestrate cloud-hosted foundation models (AWS Bedrock, OpenAI, Anthropic, Google Gemini, Meta Llama, Mistral).
- Collaborate cross-functionally with data scientists, product managers, and frontend developers to deliver end-to-end AI products.
- Ensure performance, scalability, and cost optimization of AI solutions in production environments.
- Monitor, evaluate, and continuously improve deployed AI systems.
