We are building the infrastructure layer for sovereign and edge AI - rugged, deployable compute for customers that cannot rely on centralized cloud.

Working at Armada means taking ownership, driving autonomy, and delivering impact. You’ll tackle challenges that haven’t been solved before and help build something transformative from the ground up. What you do here will not only define your career but help further Armada ’s mission to bridge the digital divide for customers around the world.

About the Role

Armada is hiring a Senior Manager, Global Payroll to own global payroll end-to-end. We are an edge AI infrastructure company with more than 500 employees across our full-time, EOR, and contractor populations, spread across 30+ US states and 11 countries outside the US. Our Payroll and HRIS run on Rippling, with EOR coverage through Rippling and through Deel in markets Rippling does not support.

This role has no direct reports today. You are the payroll function, and you will run the cycle yourself. We are hiring someone who can do that while building what comes next: the systems, the controls, the documentation, and eventually the team. The scaling work is not a stretch goal attached to this job. It is the job.

You will own the vendor relationships, act as the subject matter expert the business escalates to, and be accountable for accuracy and compliance in every jurisdiction where we pay people. As we add states, countries, and entities, you provide input on what the payroll infrastructure needs to become and then you build it. That includes evaluating additional platforms if Rippling becomes insufficient and making the case for payroll headcount when volume and complexity justify it.

There is no playbook waiting for you. You will write it.

Location. This role is remote-based on the continental US.

Main Responsibilities

- Own end-to-end payroll processing for all US employees in Rippling across 30+ states, including bi-weekly pay runs on separate schedules for hourly and salaried employees and off-cycle runs, bonuses, commissions, relocation, fringe benefits, deductions, garnishments, and final pay.

- Own payroll delivery for international and global EOR populations, coordinating with Rippling, Deel, and local providers so every jurisdiction pays accurately, on time, and compliantly.

- Own payroll tax compliance across federal, state, and local jurisdictions, including registrations, withholding and unemployment accounts, filings, amendments, and agency notice resolution.

- Own payroll readiness for expansion into new states and countries, standing up new jurisdictions inside the lead times the business works to and advising on EOR versus direct entity where the math changes.

- Own payroll's side of equity. Today that means clean data, correct treatment of any taxable equity events, and coordination with Finance and Legal. Ahead of a liquidity event, it means building the withholding, sourcing, and reporting process before we need it rather than during it.

- Prepare and reconcile payroll journal entries and payroll-related balance sheet accounts, and partner with Accounting on accruals and month end, quarter end, and year end close.

- Own year-end processing end-to-end, including W-2 production and corrections and the equivalent filings across international and EOR populations.

- Serve as primary payroll liaison
