Job Summary
Must Have:- Relevant degree. BSc / BEng / BCom in data science, statistics, informatics, engineering, or a quantitative field - completed.
- 1–5 years working with real data (analytics, reporting, engineering data, billing/consumption data, or similar). Strong internship or project evidence counts at the junior end.
- Excel to advanced level (pivots, lookups, Power Query a plus) AND at least one of SQL or Python (pandas)
- AI proficiency
- Numerical scepticism
- Clear writing
Strongly preferred:
- Utilities, metering, telemetry, or building services data exposure; time-series analysis; municipal tariff literacy.
- Dashboarding (Power BI or similar); basic scripting for automation; version-control habits.
- Evidence of self-built tools: a tracker, a pipeline, a validation script others actually used.
Key responsibilities:
Consumption & billing analytics
- Baseline demand from municipal bills and meter data; annualise partial windows correctly; flag data gaps as findings, not footnotes.
- Benchmark sites against portfolio and sector norms; identify and rank savings opportunities with rand values attached.
- Analyse tenant billing and recovery data to quantify unrecovered water on multi-tenant sites.
Telemetry & monitoring
- Work with logger and telemetry data: channel validation, night-flow analysis, burst and leak signatures, alarm triage.
- Apply and refine data-quality rules (implausible readings, stuck meters, clock drift) so alerts are trusted.
Reporting & verification
- Produce the tables, charts and appendices for audit reports and portfolio reviews in house style.
- Track actual performance of delivered projects against design intent; quantify realised savings honestly.
Data stewardship
- Keep the property, meter and project registries accurate and current; run exception queues to zero.
- Document every recurring analysis so it is repeatable by someone else — no black boxes, no key-person spreadsheets.
