About Us - FLI

FieldLine Industries is a Colorado-based quantum sensing company developing and manufacturing high-sensitivity quantum magnetometers and advanced multi-sensor systems. Our technology is being applied in a wide variety of application areas including navigation in GNSS-denied environments, unexploded ordnance detection, maritime sensing, and space systems.

Our technology sits at the intersection of quantum physics, precision engineering, and real-world deployment—transforming applications in navigation, space and geographical mapping, geophysics, defense applications, and fundamental research. We're a small, highly technical team that values solving problems together, with curiosity, rigor, reliability, and humor.

As we continue to grow, we're looking for our first dedicated Controller to build the financial foundation that supports the next stage of the company.

Working directly with the CEO, you will own FieldLine's accounting and financial operations. You'll ensure the company's financial records are accurate, timely, and decision-ready while building the financial systems that support our continued growth. 

This role is responsible for maintaining accurate financial records, managing the monthly close process, overseeing accounts payable and receivable, supporting payroll, preparing financial reporting, monitoring cash flow, and ensuring compliance with applicable accounting and tax requirements.

As a foundational member of our team, you'll also have the opportunity to improve how finance works at FieldLine. This is a high-trust, high-ownership role where your work will directly influence business decisions and help build the operational backbone of the company.

This role is ideal for someone who enjoys bringing structure and clarity to a growing organization.

You take pride in keeping the books clean, catching details others miss, and building processes that scale. You enjoy improving workflows rather than simply maintaining them, and you're comfortable working independently while partnering closely with leadership.

You're equally comfortable reconciling accounts, preparing financial reports, answering operational questions, and identifying opportunities to make financial processes more efficient.

We also value curiosity. Technology continues to change how accounting work gets done, and we're looking for someone who embraces modern tools—including AI—to improve productivity, automate routine work, and strengthen financial operations while exercising sound professional judgment.

• Retain accurate and up-to-date financial records and ensure timely month-end and year-end close.
• Process and reconcile accounts payable, accounts receivable, banking activity, and credit cards
• Prepare rolling cash forecasts, and help leadership understand upcoming funding needs and financial runway.
• Support annual financial reviews, audits, and compliance requirements as needed.
• Maintain fixed asset records and depreciation schedules.
• Coordinate with external CPA partners for tax preparation and annual financial reviews.
• Develop and continuously improve accounting processes, internal controls, and financial policies that will scale with the company..
• Leverage modern accounting software and AI-enabled tools to improve reporting, documentation, reconciliations, workflow automation, and accounting efficiency while maintaining strong financial controls.
• Contribute to the company’s capital, financial and liquidity strategies.

• Bachelor's degree in Accounting, Finance, or related field
• 5+ years of progressive accounting experience
• Strong knowledge of U.S. GAAP
• Experience owning the full accounting cycle through financial statement preparation
• Experience with accounting software such as QuickBooks Online, Sage Intacct, NetSuite, or similar ERP systems
• Excellent attention to detail and organizational skills
• Strong Excel and financial analysis skills
• Ability to work independently in a small, fast-moving organization
• Excellent written and verbal communication skills
• High level of integrity and discretion when handling confidential information

• CPA certification (active or inactive)
• Experience as a Controller or Senior Accountant in a startup or small business
• Experience supporting government contracts, SBIR/STTR programs, or defense-related organizations
• Familiarity with FAR cost principles or indirect rate structures
• Experience implementing accounting systems or improving financial processes
• Experience using AI tools to improve efficiency in accounting, reporting, documentation, or workflow automation
• Experience supporting companies moving from early-stage R&D into product commercialization

• Build something from the ground up. As our first dedicated Controller, you'll establish the accounting systems, financial processes, and financial foundation that will support the company's next decade of growth. 
• Help build the financial foundation of a growing quantum technology company
• Work directly with the CEO on strategic and operational decisions
• High ownership and visibility—you'll shape how finance operates as the company grows
• Opportunity to improve systems rather than simply maintain them
• A collaborative, thoughtful work environment where people genuinely enjoy working together
• Competitive benefits package
• A culture that values deep thinking, fast iteration, and building things that matter
• Quarterly team-building events

Finally, we believe in maintaining a healthy work-life balance and do our best to support our team in enjoying life beyond the workday. Extended, 80-hour workweeks are not part of the expectation here.
