Job Description

Mission

Design and ship AI-powered workflows, copilots, and internal tools that drive business growth and elevate Grain’s customer experience - through tight collaboration, disciplined execution, and rapid iteration.

Outcomes

Deliver 5+ “quick wins” in your first 90 days that save 20+ hours/week across non-tech teams.

Launch at least one production-grade agent/workflow with clear ROI and basic observability (usage, latency, cost).

Publish a lightweight playbook (prompt/eval templates, RAG/agent boilerplate, Slack bot kit) others can reuse.

Document what you ship and train teammates so solutions stick.

Requirements

Solid grasp of modern AI: LLMs, embeddings, RAG, agents, prompt design, evals/guardrails.

Comfortable with code: JavaScript/TypeScript or Python (both ideal).

APIs \& automation: REST/GraphQL, webhooks, OAuth, queues/cron; glue things together (POS/ERP/CRM, Sheets, Slack).

Data basics: SQL, Postgres, JSON; pragmatic ETL hygiene; debug messy real-world data.

Engineering hygiene: testing mindset, profiling/optimisation instincts, concise docs.

Owner mindset: bias to ship, learn, iterate; low-ego collaboration; clear writing.

Nice to have

Rails/Node backends; Cloudflare Workers/GCP; Docker/K8s familiarity.

Observability (logs/tracing), cost tracking for AI calls, feature flags.

Frontend for internal tools (React/Tailwind).

Security \& privacy awareness (secrets, PII minimisation).

Responsibilities

Partner with ops, culinary, finance, sales, product/engineering to uncover high-leverage problems and translate them into AI-assisted workflows.

Prototype fast (days, not weeks): ship v0, measure, iterate to v1–v3.

Build/evolve LLM pipelines (retrieval, tool-use/agents, evals, guardrails, monitoring).

Integrate systems end-to-end (APIs, webhooks, queues) to remove manual steps.

Turn proven hacks into reliable services: tests, observability, cost controls, basic security checks.

Share patterns: write docs, run demos, raise the org’s AI literacy.

What’s in it for you

Work with a fast growing, at the same time, lean and mean team, to make real world impact.

Have a lot of ownership and drive your own results and progression.

Smart people who sweat the details and push for the highest standards.

Training and in-house opportunities to help you grow.

Other benefits include a competitive compensation package and birthday leave.

You should include these in your application:
