Senior Prompt Engineer - Evaluation, Scoring and Reliability

We need an experienced prompt engineer to design reliable LLM-based evaluation and scoring workflows. You must understand semantic alignment, rubric decomposition, structured outputs, calibration, prompt sensitivity, model bias, context handling, and failure analysis - not simply write persuasive instructions. The work requires improving scoring consistency across paired inputs, distinguishing genuine meaning from superficial language overlap, and testing performance against paraphrases, contradictions, omissions, formatting changes, and adversarial cases. To apply, describe your evaluation methodology, experience building LLM judges, approach to measuring reliability, and one difficult consistency problem you solved. Include anonymised examples and tools used. Responses to this advert generated by LLMs will be auto-rejected To eliminate AI responses to the questions below, there is very special question below! 90% of AIs answer it incorrectly (its an unstable question) Advanced prequalification questions 1. You are designing an LLM judge to determine whether a supplier’s reply meaningfully addresses a buyer’s request. Replies using identical wording receive higher scores than accurate paraphrases. What is the best first intervention? * A. Increase temperature to expose the judge to more interpretations * B. Instruct the judge to assess semantic coverage, explicitly distinguish lexical overlap from meaning, and provide contrasting scored examples * C. Remove the buyer’s original request from the prompt * D. Reward replies containing the buyer’s most frequent terms 2. A reply correctly addresses four requirements but confidently contradicts a fifth, critical requirement. Your judge often gives it a high overall score. Which rubric design is strongest? * A. Ask for a holistic score based on overall helpfulness * B. Score each requirement separately, identify contradictions, apply a critical-failure rule, and then calculate the overall result * C. Tell the judge to penalise inaccurate responses * D. Increase the maximum score so errors have less influence 3. Two semantically equivalent replies receive materially different scores when their order, formatting, or writing style changes. Which evaluation approach best isolates the problem? * A. Run each version repeatedly, randomise irrelevant presentation features, and measure score variance by transformation type * B. Reduce both replies to the same word count * C. Set temperature to 1.0 and compare one result from each * D. Ask a larger model which reply is better 4. An LLM judge must assess whether a response covers every material element of a complex request. Which prompt architecture is most robust? * A. Ask for one immediate score to minimise token usage * B. First extract atomic requirements, then map response evidence to each requirement, classify coverage, and derive a schema-constrained score * C. Ask the model to explain its reasoning before reading the response * D. Provide a long definition of quality and request a percentage 5. Your judge achieves 92% agreement with human labels, but performance falls sharply on short, indirect, or poorly written inputs. What should happen next? * A. Deploy because overall agreement exceeds 90% * B. Add more examples of well-written inputs * C. Segment results by input characteristics, build targeted adversarial cases, revise the rubric, and recalibrate against disputed human-labelled examples * D. Increase the system prompt’s authority and repeat the same test 6. A candidate claims that requiring detailed chain-of-thought will make scoring more accurate and auditable. Which response shows the strongest understanding? * A. Correct; longer reasoning always improves accuracy * B. Correct, provided temperature is zero * C. Not necessarily; use explicit intermediate classifications and evidence fields, validate outputs, and evaluate accuracy empirically without depending on unrestricted hidden reasoning * D. Incorrect; LLM judges should return only a number Please answer each question with A,B,C orD. For each, add your percentage certainty of your answer and your reasoning.

AI Engineer — AWS Bedrock AgentCore

We're looking for engineers to help build and productionize AI systems on AWS Bedrock AgentCore — real conversational AI, RAG pipelines, and agent architectures that go well beyond proof-of-concept and serve live traffic and real users. Whether your strength is on the AI application side (agents, RAG, orchestration) or the platform side (deployment, observability, security), this role sits at the center of turning working demos into production-grade, reliable systems on Bedrock's agentic stack. If you've built and shipped on AgentCore specifically — not just Bedrock in general — and want your work to run in production rather than sit in a notebook, this is built for that. What You'll Do - Design, build, and deploy conversational AI systems, chatbots, and AI agents using AWS Bedrock AgentCore - Architect and ship production-grade RAG (Retrieval-Augmented Generation) systems — not prototypes, but systems serving live traffic - Build and deploy LLM applications primarily on AWS Bedrock and AgentCore, with Azure OpenAI or equivalent platforms as secondary context - Develop and orchestrate agent architectures within AgentCore, using frameworks such as LangChain, LangGraph, or LlamaIndex where applicable - Build and maintain MCP (Model Context Protocol) server integrations to extend AgentCore agent capabilities - Design and build the production service layer around AgentCore (Lambda, API Gateway, IAM, DynamoDB, OpenSearch, or equivalents) - Establish CI/CD pipelines and manage development, beta, and production environments for AgentCore-based services - Implement observability for AgentCore agents: tracing, dashboards, per-turn cost and latency metrics, error rates, and audit trails - Implement key security controls — data-leakage protection, session isolation, auth/authz boundaries, secure prompt/response storage - Write clean, maintainable, production-quality Python across the AI application and platform stack - Monitor, evaluate, and iterate on agent, RAG, and platform performance in production - Stay current with fast-moving developments in Bedrock, AgentCore, and agentic AI systems, and bring relevant advances into the project What You Bring - Proven, hands-on experience building and deploying AI agents on AWS Bedrock AgentCore in a production environment — not personal projects or tutorials - Direct experience with AWS Bedrock's agentic tooling (AgentCore, Bedrock Agents, or equivalent Bedrock-native orchestration) - Strong Python skills for AI application development and/or service integration - Working experience with AWS cloud environments; Azure experience is a plus but not the primary requirement - Experience with at least one of: agent orchestration frameworks (LangChain, LangGraph, LlamaIndex), RAG system design, or AWS production infrastructure (Lambda, API Gateway, IAM, DynamoDB, OpenSearch) - Experience with observability and monitoring for AI or distributed systems - Strong understanding of security, data handling, and production-readiness tradeoffs - Comfortable working in a fast-moving, evolving technical environment with pragmatic engineering judgment
