    Who We Are:
    At Aventia, we provide a comprehensive suite of environmental consulting, field services, and technology-driven solutions designed to help clients navigate increasingly complex environmental and operational challenges. Established in 2022, Aventia is built on a commitment to creating a better future for our clients, our communities, and our employees. At Aventia, every employee plays a vital role in helping clients succeed while contributing to a more sustainable future.
    As part of our Team, you'll have the opportunity to work alongside talented professionals on meaningful projects that positively impact communities, industries, and the environment. As a growing organization, we offer the chance to expand your skills, advance your career, and make a visible contribution to our continued success.
    Position Summary:
    The Project Accounting Technician supports transactional project accounting activities, including billing, project setup, data entry, documentation, and coordination with project managers and internal teams. This role requires accuracy, organization, and strong communication skills to help ensure project and billing information is complete, timely, and aligned with client contract requirements. The ideal candidate is detail-oriented, process-driven, comfortable working in accounting ERP systems, and able to manage competing priorities in a fast-paced, project-based environment. This is a full-time, in-office position.
    Position Responsibilities:
    • Assist with project setup in the accounting system, including inputting contract terms, billing methods, rate tables, and related project information.
    • Develop working relationships and maintain clear communication with project managers to ensure project and billing information is accurate and up to date.
    • Generate and submit invoices in accordance with client contracts, billing schedules, and project milestones.
    • Support data entry and maintenance of accurate project financial records in Deltek and other internal accounting systems.
    • Coordinate with project managers and internal staff to gather required documentation for billing, project initiation, and client submissions.
    • Monitor billing status, documentation completeness, and follow-up items to support timely invoice processing.
    • Review subconsultant invoices and supporting documentation for completeness before submission to accounts payable.
    • Maintain and update billing logs, tracking tools, and internal reports to support accurate invoice documentation and timely submissions, including uploads into client or federal invoicing portals such as WAWF (Wide Area Workflow), as applicable.
    • Assist in preparing audit-ready billing and project records, including organized backup documentation and related correspondence.
    • Provide general administrative and project accounting support to the finance and project teams, responding to internal and external requests as needed.
    • Support accounts receivable and collection efforts by monitoring outstanding invoices, following up on payment status, maintaining collection notes, and coordinating with project managers and clients to help resolve payment delays or invoice issues.

    Experience/Education Requirements:
    Applicants must have:
    • Ability to pass background check.
    • 3+ years of experience in accounting, billing, project accounting, or financial administrative support.
    • High school diploma or equivalent required; associate or bachelor's degree in accounting, finance, business administration, or a related field preferred.
    • Experience working in or supporting project-based businesses is required; architecture and engineering (A&E) industry experience is preferred.
    • Hands-on experience using accounting ERP systems is required. Deltek Vision or Deltek Vantagepoint experience preferred.
    • Proficiency in Microsoft Excel, including basic formulas, formatting, sorting, filtering, and data review.
    • Ability to follow established procedures, manage competing priorities, and meet time-sensitive billing deadlines.
    • Strong attention to detail, accuracy, organization, and time management skills.
    • Strong verbal and written communication skills, with the ability to build effective working relationships with project managers and internal teams.

    Physical Requirements:
    • Ability to perform work in a professional office environment, including prolonged periods of sitting at a desk and working on a computer.
    • Ability to use standard office equipment, including a computer, keyboard, mouse, telephone, scanner, copier, and printer.
    • Ability to occasionally stand, walk, bend, reach, and retrieve or file documents in an office setting.
    • Ability to occasionally lift and/or move office materials or files weighing up to 15 pounds.

    Work Environment & Travel:
    • Routine travel is not expected; occasional travel or in-person meetings may be required based on business needs.
    • The role may require flexibility during month-end, billing cycles, or other deadline-driven finance activities.

    What You Will Get:
    This is a full-time role with compensation commensurate with experience and expertise. Aventia offers a robust and competitive benefits package that includes a 401(k) with company match, comprehensive medical, dental, and vision coverage, short- and long-term disability, life insurance, and flexible spending account options.
    You'll also benefit from a generous paid time off program that includes nine paid holidays annually, vacation time, and wellness leave, along with strong support for continuing education and professional development.
