Launch Your Accounting Career Behind Life-Saving Medical Devices

At Life Science Outsourcing (LSO), the numbers are never just numbers. As a medical device contract manufacturer operating under FDA regulations and ISO 13485 standards, we depend on financial records that are accurate, timely, and audit-ready, because everything we build ends up in the hands of a patient. The Junior Accountant keeps the payables and receivables engine running so quality products ship on time and within budget.

If you are starting your accounting career and want a role where the details genuinely matter, where a mentor invests in your growth, and where you will learn modern AI and automation tools most entry-level jobs never touch, this role was built for you. Recent graduates are encouraged to apply.

As a key member of our Finance team reporting to the Controller, you will own the day-to-day flow of accounts payable and accounts receivable, serving as a vital link between vendors, customers, and our operations floor.

• Receive, verify, and reconcile vendor invoices against purchase orders and receiving documentation so every payment goes out right the first time.
• Record payments, prepare payment runs, and keep vendor accounts accurate and current.
• Respond to vendor inquiries promptly and professionally, resolving billing discrepancies at the source.

• Generate and issue customer invoices accurately and on schedule, keeping cash flowing into the business.
• Apply incoming payments, monitor outstanding balances, and assist with collections follow-up.

• Working understanding of basic accounting principles, including AP, AR, and invoice reconciliation.
• Proficiency in Microsoft Office, especially Excel, plus Word and Outlook.
• Comfort learning an ERP or accounting system;
  Deacom experience is a plus, not a requirement.
• Ability to communicate effectively, both orally and in writing.

• Detail‑oriented to the core: a transposed digit bothers you until it is fixed.
• Organized and steady when invoices stack up and deadlines compete.
• Curious about AI and automation, and eager to apply modern tools that make routine AP and AR work faster and more accurate. Hands‑on experience is a bonus; willingness to learn is what matters.
• A team player who takes direction well, asks smart questions, and wants to grow with a team that will invest in you.

• Exposure to a manufacturing or contract manufacturing environment.
• Familiarity with vendor relations or customer billing.
• Certificate in Accounting or Bookkeeping.
