Job description

Senior Cost Analyst — St. Johnsbury

MMG Industrial Group

Reports to: Group Controller

Location: St. Johnsbury, VT — on-site; this is a hands‑on, site-based role

Direct Reports: None — individual contributor

Division: MMG Industrial Group

Employment Type: Full-time, exempt

Position Summary

MMG is seeking a Senior Cost Analyst to own standard cost accounting and inventory valuation at its St. Johnsbury, VT site, a core Industrial division manufacturing location. This is an individual-contributor role reporting to the Group Controller, focused on the technical rigor of cost accounting: setting and maintaining standard costs, driving variance analysis to root cause, and ensuring inventory is valued accurately and defensibly for both internal reporting and external audit. The role works day‑to‑day alongside site operations and accounting staff but does not carry people‑management responsibility — the value delivered is analytical depth and cost‑accounting discipline.

Key Responsibilities

• Own the standard cost‑setting process for the site — establish and maintain standard costs at the part and routing level and lead the annual (or as‑needed) standard cost roll in coordination with the Group Controller.
• Drive monthly variance analysis — work‑order variance, purchase price variance, absorption variance — down to root cause, and present findings in terms operations leadership can act on.
• Own inventory valuation integrity: reconcile perpetual inventory to the general ledger, manage cycle‑count and physical‑inventory reconciliation, and maintain excess‑and‑obsolete (E&O) reserve analysis on a recurring schedule.
• Maintain BOM and routing accuracy in the site's ERP costing module in partnership with engineering and operations, flagging discrepancies that distort standard cost before they reach the close.
• Support month‑end and quarter‑end close for all cost‑accounting and inventory‑related entries, on the calendar set by the Group Controller.
• Build and maintain Excel‑based costing models, variance dashboards, and ad hoc analyses; use AI‑enabled tools to accelerate data reconciliation, variance root‑causing, and reporting turnaround.
• Support external audit requests related to inventory valuation, standard costing, and E&O reserves with organized, audit‑ready documentation.
• Partner proactively with the Industrial Division Controller and site operations leadership on costing questions tied to new part introduction, make/buy decisions, and margin analysis.
• Escalate cost‑accounting control gaps or data‑integrity risks to the Group Controller directly rather than resolving unilaterally.

Qualifications

• Bachelor's degree in Accounting, Finance, or related field.
• 5–7+ years of progressive cost accounting experience in a manufacturing environment, with direct ownership of standard costing and variance analysis.
• Advanced Excel proficiency required — complex formulas, pivot tables, and financial/costing models built and maintained independently.
• Working familiarity with AI‑enabled analysis tools (e.g., Excel Copilot, Claude, or similar) and a demonstrated ability to apply them to accelerate reconciliation and analysis work.
• E2 (Shoptech) or JobBoss2 ERP experience strongly preferred; general comfort with ERP costing/inventory modules required at minimum.
• Demonstrated technical command of standard costing, BOM/routing structures, absorption and work‑order variance, and E&O reserve methodology.
• Comfortable operating as an individual contributor without a supervisory layer — able to drive analysis independently and communicate proactively with a Group Controller who is not always on‑site.
• Aerospace, defense, medical device, or semiconductor OEM manufacturing experience a plus.

First 90 / 180 Days — Success Metrics

90 Days

• Complete a full audit of the site's current standard costs against actual BOM/routing data; document discrepancies and a remediation plan.
• Deliver the first full month‑end variance analysis package on schedule, reviewed and accepted by the Group Controller.
• Establish a current, reconciled E&O reserve schedule with clear methodology.

180 Days

• Lead the site's next standard cost roll independently, with the Group Controller in a review — not hands‑on — role.
• Reduce unexplained/unresolved variance line items to a defined threshold for two consecutive months.
• Have a documented cycle‑count program in place with reconciliation accuracy meeting group standards.
