Technical Services SupervisorLocation: Johannesburg with national travel as the service base grows Team: 1–3 technicians initially, expected to grow Package: R30-35k CTC Type: Permanent, on-siteWhy the Role ExistsThe after-sales service function does not scale past the owner, and it is now costing money in three visible ways:Warranty claims are not being recovered. Parts are being replaced and either billed to clients who dispute it, or absorbed — without claims being lodged against the manufacturer. Commissioning and asset records are incomplete, so warranty entitlement can't be established quickly when a client queries an invoice. Faults are being treated symptomatically. Components get replaced without a documented root cause, so the same failure recurs and the warranty position can't be defended. We need someone to own the service function end-to-end and turn it from reactive callouts into a managed, profitable department. What They Will OwnJob planning and scheduling — technician diaries, callout prioritisation, response-time commitments, minimising weekend and after-hours premium work. Spares and stock control — critical spares holding for the brands we carry, van stock, reorder levels, lead-time management on imported parts. Warranty administration — commissioning register, entitlement checks, claim lodgement and recovery against manufacturers, and the technical write-up that supports a claim or defends a rejection. Fault management — root-cause discipline on every significant failure: diagnostic sequence, photographic evidence, findings recorded on the job card. Technician supervision — allocation, quality of workmanship, training plans, safety and compliance, and developing the team as it grows. Client-facing technical authority — explaining a finding to a chef or a facilities manager and holding the line on a charge when the finding supports it.
