Hadrian - Manufacturing the Future

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen.

If you’re ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you’re exactly who we’re looking for.

We are looking for an Accounts Payable Manager to lead and scale our AP function. This role will own the end-to-end AP process, manage and develop the AP team, and drive the standardization and controls we need as we grow across multiple entities.

Our processes are actively evolving. We need a leader who can bring order to a dynamic environment — building repeatable, well-documented workflows and stronger controls — while staying close enough to the details to jump in on complex invoices, coding decisions, and month-end close. The right person sets the standard for documentation and knowledge sharing, and continuously looks for ways to improve how AP runs.

• Lead the AP team. Lead, mentor, and develop the AP team, including AP Specialists — setting priorities, reviewing work, managing workload across a high volume of invoices, and building bench strength as we scale.

• Own the AP process. Own the full accounts payable process end to end — invoice intake and coding, PO and non-PO matching, approvals, payment runs, vendor onboarding, credit cards, and reimbursements — across multiple entities, cost centers, departments, and locations.

• Standardize & document. Design, document, and standardize AP policies, workflows, and coding guidance; drive the ongoing centralization of AP as the company grows and adds entities.

• Controls & compliance. Establish and enforce internal controls, approval thresholds, and segregation of duties; ensure compliance and audit readiness.

• System ownership. Own and optimize our AP systems — Net Suite (ERP) and Ramp (OCR / spend) — including configuration, integrations, automation, and data integrity between platforms.

• Vendor management. Manage the vendor program: vendor setup and onboarding standards, W-9 / documentation collection, master-data accuracy, and 1099 reporting.

• Month-end close. Own AP month-end close: accruals, prepaids, fixed-asset coding, reconciliations, and reporting; ensure the sub-ledger ties to the GL and close deadlines are met.

• Escalations & judgment. Resolve escalated and complex items — intercompany chargebacks, disputes, and transactions that don’t fit standard templates — and set the guidance so the team can handle them going forward.

• Payments & cash flow. Manage cash-out timing and payment scheduling in partnership with Treasury / Finance; monitor aging, discounts, and vendor relationships.

• Metrics & reporting. Define and track AP metrics (volume, cycle time, aging, exception rates) and report on performance and process-improvement initiatives to Finance leadership.

• Cross-functional partner. Partner cross-functionally with Procurement, Operations, and department leaders to resolve issues, improve intake quality, and support company growth.

• 10+ years of accounts payable experience, including 2-3+ years managing or leading an AP team or function.

• Proven experience owning full-cycle AP in a high-volume and/or multi-entity environment.

• Strong command of both two-way / three-way matching and non-PO…
