Senior Software Engineer, AI Platform (Remote)

Weedmaps is hiring a Senior Software Engineer for its AI Platform team. The role builds and operates production AI agents, shared agent infrastructure, and retrieval and knowledge systems, while improving their evaluation, cost, latency, security, and reliability.

Responsibilities:

• Design, build and operate production AI agents, including an autonomous coding agent that works from Jira and Slack, opens PRs, fixes its own CI failures and applies review feedback
• Build the retrieval and context layer behind our "AI brain": embeddings and semantic search, knowledge-graph modeling, and integration with our Snowflake semantic layer and internal docs, so agents pull the right context in one pass instead of several
• Extend our internal MCP server with shared skills, tools and processes that other teams can reuse, and help product teams bring agents into their own workflows
• Own evaluation: build offline test sets and online metrics that show whether a change to a prompt, model or retrieval step made an agent better or worse, and gate releases on them
• Drive cost and latency down: route work to the cheapest model that can do it, use caching and structured outputs, and track spend per agent and per task on AWS Bedrock
• Harden agents against prompt injection, memory poisoning and over-broad permissions: least-privilege tool access, auditable actions, human approval where the risk warrants it
• Instrument agents with tracing and logging so failures can be diagnosed and fixed quickly, and take part in on-call for the systems you own
• Evaluate new models and tools with a practical eye, adopting what holds up and passing on what doesn't
• Write clear design docs, review code, and mentor other engineers on building with LLMs
