Job description

AI/ML: OCR & doc parsing (DeepseekOCR/Tesseract/PaddleOCR/Doc AI), LLM-assisted extraction & entity resolution (embeddings + fuzzy + human-in-the-loop), policy compiler (CEL/OPA)

Cloud/DevOps: GCP (Cloud Run/Functions), Docker/K8s, Terraform, GitHub Actions

Security/Observability: RBAC, encrypted secrets, immutable audit log, OpenTelemetry, Prometheus/Grafana

Why Join

Build the next-generation agentic system of action: Create autonomous systems that run entire supply chains, parsing messy PDFs and emails, forecasting demand, sending invoices, routing shipments, and managing real money.

Engineer trust at scale: Design safety-critical infrastructure with true reliability - idempotency, compensations, exception handling, and audit-grade transparency - the backbone that lets brands hand over their operations to AI.

0 to 1 ownership: Join at inception; shape architecture, product, and culture with direct customer exposure and founder collaboration.

Cutting-edge tech stack: TypeScript · Python · NodeJS · React/Next.js · Temporal · Kafka · PostgreSQL · Redis · GCP · Docker/K8s · OCR · LLMs.

Culture of excellence: We believe excellence is built in the details - in the "mundane" things done exceptionally well. Like Olympic teams, we treat habits, systems, and small improvements as our competitive edge. The difference between good and world-class isn't effort alone, but how we work: precise, consistent, and always improving.

Requirements

  • 3 to 8 years of end-to-end software development (or proof of exceptional talent)
  • Proven ability to design, build, and deploy complex production systems from scratch
  • Hands-on experience across the whole stack (frontend + backend + infra)
  • Strong CS fundamentals, fast learner, curiosity for real-world ops problems

We love candidates with:

  • Early-stage or founding engineer experience
  • Experience building distributed systems and/or workflow orchestration (Temporal, Camunda)
  • Strong Data and AI skillset (OCR, NLP, agentic workflows)
  • Background in ERP, retail, or CPG

Traits We Value:

  • Curiosity - learns and experiments fast
  • Systems thinking - connects data, architecture, and business logic
  • Builder mindset - ships 0 to 1 systems from scratch
  • Pragmatism - knows when to ship vs. refactor
  • Ownership & autonomy - thrives in ambiguity
  • Clarity & collaboration - writes clean design docs and PRs
  • Bias for simplicity - elegant systems > clever hacks

️ Architecture & Tech Stack

Backend: Node.js, Python

Frontend: React/Next.js

Workflow: Central orchestrator (Saga style) with Temporal for durable execution

Messaging: Kafka/RabbitMQ; transactional outbox; idempotent actions

Data: PostgreSQL, Redis; normalized schemas; schema-versioned pipelines

Benefits & conditions

Cash: £90-120K p.a. base

Equity: At least 2% with the possibility to increase depending on performance

About the company

It replaces hours of manual work done by ops teams using spreadsheets and ERPs, allowing CPG businesses to focus on growth, not supply chain. Over time, Sarah AI will evolve into the AI-native operating system for CPG brands, replacing legacy ERPs with a unified system of action that actually runs the business
