Corporate Controller

Machine Sciences Corporation, founded in 2001 and based in Tualatin, Oregon, is a high-precision manufacturing partner for the world’s most demanding technologies. The 72,000 sq ft, ISO & AS9100-certified facility runs 24/7 with nearly 150 engineers and machinists, spanning rapid prototyping through full production, 5-axis and mill/turn machining, and exotic material work for aerospace, defense, space, next-gen transportation, and medical customers.

Machine Sciences is a portfolio company of Viking Global Capital.

Reporting to the CFO, the Platform Corporate Controller is the senior-most accounting executive across the Machine Sciences platform. This is a foundational hire to support a private equity-backed buy-and-build strategy: own the consolidated books, build the corporate accounting function from the ground up, and scale the people, process, and systems for a multi-site, multi-entity platform. Day-to-day scope spans the consolidated close, technical accounting and GAAP compliance, internal controls, financial reporting, treasury, tax coordination, cost accounting and operational performance reporting, payroll, and the external audit.

The Controller is also the accounting workstream lead on every acquisition — partnering with the CFO and VP of M&A on diligence, purchase accounting, chart-of-accounts harmonization, ERP integration, and the Day 1 through Day 100 financial integration playbook that turns a closed deal into a fully consolidated business unit.

A technically excellent, builder-minded Controller energized by white-space — part architect (designing the platform finance org), part operator (running a flawless close), and part integrator (absorbing acquired entities without drama). Comfortable in the trenches on a job costing issue one day and presenting consolidated results to the sponsor the next. Must include:

• CPA with a strong technical accounting foundation, ideally Big 4 trained
• Proven Controller in a private equity backed, multi-site, multi-entity environment
• Manufacturing experience with deep fluency in cost accounting, job costing, WIP, and operational performance analysis
• Demonstrated M&A integration leadership including purchase accounting and ERP harmonization
• Track record of building and leading high performing accounting teams across multiple locations
• Willingness to be on-site in Tualatin and to travel to acquired sites as the platform scales

• Own the consolidated month-, quarter-, and year-end close across all entities, plus the general ledger, chart of accounts, intercompany framework, and accounting policy manual.
• Deliver timely, accurate consolidated financial statements with variance analysis for the CFO, CEO, sponsor, and lenders.
• Establish SOX-style internal controls and ensure compliance with US GAAP and applicable federal, state, and local reporting requirements.

• Serve as the platform’s technical accounting authority on revenue recognition (ASC 606), leases (ASC 842), business combinations (ASC 805), inventory and cost accounting, stock-based compensation, and other areas as they arise.
• Own the annual external audit end-to-end: serve as the primary point of contact for auditors, manage the PBC list and timeline, and drive a clean, well-documented audit with minimal adjustments.

• Lead the accounting workstream on every acquisition from LOI through Day 100 — quality of earnings, working capital pegs, and net debt with the CFO and VP of M&A.
• Own purchase accounting, opening balance sheets, valuation coordination, and post-close true-ups.
• Harmonize chart of accounts, policies, close calendars, and reporting packages across acquired entities, and continuously improve the Day 1–100 integration playbook.

• Own the operational performance reporting framework — job-level margin, labor and machine efficiency, overhead absorption, scrap, and yield — and translate variances into specific job costing actions the floor can execute against.
• Deliver job costing and project profitability data the floor…
