Controller

TAR•Austin, TX

48d•Onsite

About The Position

TAR's mission is to power intelligence for the world by building the world’s first off-grid power plant for data centers powered by renewable technologies. They are focused on delivering GW-scale power faster than anyone by rethinking every layer of the stack, vertically integrating to solve every bottleneck. TAR is both a hardware and software company building massive, critical, physical infrastructure, working directly with one of the largest compute providers to scale and deploy 5GWs by 2028. They operate on principles of high ownership, high agency, speed, first principles, and passion. As Controller, you will own the entire finance function. This includes verifying and paying vendor invoices, issuing accurate customer invoices, performing monthly closes, and maintaining precise knowledge of cash positions. This is a hands-on builder role for a senior operator, based in Austin (on-site preferred). You will take over the current spreadsheet-based finance operations, perform the tasks yourself, and build the necessary systems, controls, and team to scale from a single project to a multi-GW platform.

Requirements

7+ years of progressive accounting experience with full ownership of a monthly close; CPA strongly preferred.
Hands-on AP and AR ownership at real volume: PO matching, approval workflows, payment execution, customer billing, and collections.
Working command of payment fraud controls; you can describe your vendor bank-detail verification process and approval matrix from memory.
Strong GAAP fundamentals, comfortable with accruals, capitalization, and multi-entity and intercompany accounting.
Experience implementing or administering an ERP (NetSuite, Sage Intacct, or similar) and modern AP and expense tooling.
Extreme attention to detail and comfort being the person the buck stops with, in a fast, ambiguous, early-stage environment where you do the work rather than delegate it.

Nice To Haves

Construction or energy project accounting: WIP, percentage-of-completion, retainage, and job cost codes.
SPV or project-entity consolidation, lender draw requests, and investor reporting.
ITC or tax credit basis documentation experience.
First finance hire at a startup, or Big 4 audit training with energy or construction clients.

Responsibilities

Own accounts payable end to end: verify vendor invoices against POs, contracts, and delivery or milestone documentation, route them for approval, and execute payment on schedule.
Run payment controls that make fraud impossible: verified vendor master data, callback verification of bank detail changes, dual approvals on large payments, and a clean audit trail on every disbursement.
Own accounts receivable: issue POs and invoices to customers and offtakers, track contract milestones and payment terms, and manage collections.
Run the monthly close, including reconciliations, accruals, and intercompany entries across parent and project entities, and deliver timely GAAP financial statements.
Own project cost accounting: track actuals against budget by cost code, manage retainage and lien waivers, and give the delivery team real-time visibility on spend.
Work with outside tax advisors to maintain equipment cost basis and tax credit documentation, including safe-harbored equipment, and support audits, lender reporting, and diligence with defensible numbers.
Manage cash across operating and project accounts: banking relationships, cash forecasting, and funding so payments never wait on money movement.
Own the finance stack: select and implement ERP, AP, and expense tooling, then hire and build the accounting team as transaction volume scales.
