About the Role

AI Runtime Services owns the shared runtime that AI at Demandbase runs on — two ways. First, it's the layer that enables and supports the AI features in the Demandbase platform: product teams ship LLM features on top of it without reinventing model access, spend control, safety, and observability. Second, the team builds and supports internal AI solutions — the tooling and services the company uses to work with LLMs day to day. The pillars underneath both: the LLM gateway, cost controls, observability, evals infra, caching, and guardrails.

The surface is broad and the team is early. You won't be handed a narrow slice: expect to move across the gateway one week and the ingest pipeline the next — and across product-facing runtime and internal tooling — and to own what you build in production.

What you'll own

- The LLM gateway. The single front door to every model provider we use — keys, routing, rate limits, failover, provider quotas. When it's down, every AI feature at Demandbase is down.

- Reliability, for real. SLOs, on-call, incident response, and the postmortems for the runtime. This is a genuine SRE ownership role, not "build it and let someone else run it."

- Cost control. Per-team and per-model attribution, budgets, quotas. LLM spend is the kind of line item that quietly triples; your job is to make it legible and then make it smaller.

- LLM observability. Traces, spans, prompt/response capture, ingest and billing visibility for every AI feature in the company.

- Evals and experimentation infra. The shared harnesses, datasets, and scoring plumbing product teams use to know whether a prompt or model change actually made things better.

- Caching and guardrails. Response and semantic caching to cut latency and redundant spend; input/output safety, PII handling, and policy enforcement at the gateway.

What we need

- Strong production infrastructure background: Kubernetes, AWS, Terraform, GitOps. You've operated systems that people were paged for, and you've been the one paged.

- Python, at a level where you're comfortable owning services and tooling in it — not just scripting.
