About your role: We’re looking for an AI Engineer who wants to build production-grade AI systems, not just experiment with demos. This is a high-ownership, greenfield role where you’ll help build our AI platform from scratch, working directly with the Head of AI. You’ll own initiatives end-to-end - from discovery and architecture decisions to production delivery - and play a key role in shaping how AI is used across the company.
You’ll work with a modern AI stack including Claude/OpenAI/Bedrock, RAG pipelines, eval frameworks (Promptfoo, Ragas, LangSmith), and agentic patterns. This role is ideal for someone who enjoys autonomy, strong engineering ownership, and proactively identifying the next highest-leverage opportunity to drive into production.
In this role, you will
Design and build RAG and automation workflows inside our VPC environment.
Create integrations across engineering, communication, and knowledge-management systems (Jira, Confluence, Slack, Google Drive, Git).
Develop AI-powered pipelines for code quality checks, ticket auto-classification, documentation updates, release notes, and meeting summaries.
Work on prompt engineering, model selection and routing (Haiku / Sonnet / Opus), and workflow optimization.
Build evaluation and regression frameworks for AI workflows to prevent model-upgrade regressions.
Create lightweight dashboards for engineering leads to surface delivery patterns and bottlenecks.
Own initiatives end-to-end: scope → design → ship → measure → iterate.
It’s all about you
5+ years of production experience with Python (services, async, API integrations, clean and testable code).
Hands-on experience with LLM APIs in production: Anthropic Claude (Opus/Sonnet/Haiku), OpenAI, AWS Bedrock.
Strong understanding of RAG systems: chunking, embeddings, hybrid search, re-ranking, grounding/citations.
Prompt engineering + structured outputs + tool/function calling.
Experience with eval/regression frameworks: Promptfoo, Ragas, LangSmith, or custom evaluation harnesses.
Agentic patterns: ReAct, function-calling loops, fallbacks.
Vector databases: pgvector, Pinecone.
Workflow orchestration: n8n, Airflow, or custom orchestration systems.
Observability: token-spend tracing, latency monitoring, model routing.
Solid AWS fundamentals: IAM, Lambda, S3, CloudTrail - comfortable deploying inside VPC environments independently.
CI/CD + pipeline hooks (GitLab/GitHub), webhooks, event-driven architectures.
Basic SQL skills for analytical queries and metrics dashboards.
Driver mindset: proactively identifies the highest-leverage opportunity and drives it to production
B2 English level
Real REST integrations with 2-3+ APIs
Experience with workflow orchestration tools.
Prompt evaluation tooling such as LangSmith is nice to have
Experience with Docker
RAG experience: embeddings and vector stores (pgvector, Pinecone, or similar) for knowledge base use cases
