About the role

Key responsibilities & impact

You’ll join the Agentic Ants team as our second native AI engineer.
You’ll build and extend our agentic systems alongside the rest of the team — new tools, sub-agents, prompt iterations — and co-own the evaluation framework that gates every change: golden datasets, LLM-as-judge pipelines, regression suites, production-trace mining.
Work across both Synera MAS and Synera Assistant, picking up reliability concerns (error handling, retries) as they show up in your work.
Partnering with the wider engineering team, help the team go deeper on customer insights data.
Kick off sprint planning, review traces, flag failure modes, work on datasets, join team syncs, integrate CI, pair with engineers, review outputs, refine rubrics, share findings.

Requirements

What you’ll need

You resonate with Synera's Core Values - they're central to how we work, and we'll explore them together in your first interview.
You’ve designed and shipped agent graphs in production with LangGraph or equivalent — supervisor / sub-agent patterns, tool design, prompt iteration.
You’ve built or meaningfully contributed to an LLM evaluation pipeline — LLM-as-judge design, calibration against human labels, dataset versioning, and the statistical reasoning behind it (CIs, sample sizes, false positives).
You write production-grade Python (FastAPI, PostgreSQL).
You’ve worked with at least two of Anthropic, OpenAI/Azure, Bedrock, or Vertex AI.
You’re familiar with Langfuse, LangSmith, or similar tracing tools.
You handle reliability when it shows up in your work — retries, error handling, graceful degradation.
SLO thinking is a plus.
You communicate clearly and push back when you disagree.
