Data / ML Engineer

Why this role ๐ŸŽฏ

Our forecasting algorithm and time-series models are already built. What we need now is someone to make them run reliablyโ€”ingesting messy client data, maintaining our GCP/BigQuery infrastructure, and shipping outputs consistently as we scale from pilot to production. This role owns that.

Who you are

You're a Data/ML Engineer with strong software engineering instincts. You write clean Python, you're comfortable wrangling dataframes, and you know how to build pipelines that don't break at 2am.

Required

๐Ÿ 1โ€“3 years of commercial experience in data engineering, ML engineering, or a similar role

๐Ÿ› ๏ธ Strong Python skills with hands-on pandas/dataframe experience

๐Ÿ” Experience building and running data pipelines (ETL/ELT) with orchestration tools

โ˜๏ธ Familiarity with cloud platforms (GCP preferred) and tools like BigQuery

๐Ÿ—‚๏ธ Comfortable working with messy, real-world dataโ€”CSV ingestion, schema validation, inconsistent formats

๐Ÿš€ Able to deploy and monitor models and pipelines in production

๐Ÿ“Š Can build and maintain dashboards to give the team and clients real-time visibility into model health and forecast outputs

๐Ÿค– You love AI tools and use them to build shit fastโ€”Cursor, Claude, Copilot, whatever gets the job done

๐Ÿ“ฃ Clear communicator who documents well and cares about reliability, not just shipping fast

๐Ÿ’ƒ Excited to work in a small, fast-paced startup where you'll take ownership and jump in wherever needed

Desirable

๐Ÿง  Enough statistics/ML knowledge to retrain, tune, and troubleshoot modelsโ€”not just wrap APIs

๐Ÿ—๏ธ Experience owning infrastructure: environments, dependencies, CI/CD, rollbacks

๐Ÿณ Familiarity with containerisation (Docker) or infrastructure-as-code

๐Ÿฝ๏ธ Interest in food retail, fresh food, or supply chain domains

What the job involves

Data pipelines ๐Ÿ” โ€” Build, maintain, and improve our ETL/ELT pipelines. Ingest messy client data (CSV exports, varying formats, schema mismatches) and transform it reliably for forecasting.

Production systems ๐Ÿš€ โ€” Deploy statistical/ML models and keep them running at scale. Monitor pipelines and models, set up alerting for failures and data quality issues.

Visibility ๐Ÿ“Š โ€” Build dashboards so the team and clients can see model health and forecast outputs in real time. Surface insights when performance drifts.

Infrastructure โ˜๏ธ โ€” Own our GCP environments, BigQuery setup, dependency management, and release processes.

Code quality โœ… โ€” Write well-structured, tested Python with proper version control practices (branching, PRs, code review).

Client onboarding ๐Ÿ“ฆ โ€” Own the end-to-end process from receiving a client's first data extract to delivering clean forecast outputs.

Collaboration ๐Ÿค โ€” Work closely with our Head of Data Science to run, maintain, and troubleshoot existing models. Document systems and runbooks clearly.

Team & reporting ๐Ÿ‘ฏ
  • You'll be the first dedicated Data/ML Engineer, working directly with the founder (who loves using AI to build stuff and has a background in UX and product) as their technical sidekick. You'll also collaborate closely with our Head of Data Science and the rest of the founding team. This is a high-impact role where you'll shape how we build and scale our technology, data infrastructure from day one.
