Job description

Senior Legal Billing Associate | Asset Management Legal Team

Boston, MA | Hybrid: 3 days in office, 2 days remote

Bring your law-firm billing experience in-house—and help shape the function.

Origin Staffing is partnering with an established private investment firm to hire a Senior Legal Billing Associate for a newly created position. This opportunity is well suited to a law-firm billing professional who wants broader responsibilities, exposure to private equity, and the chance to help improve how an organization manages its legal spending.

You’ll move to the client side of the relationship: working with outside law firms, internal legal professionals, and finance teams to keep invoices moving, strengthen reporting, and make billing processes more efficient.

This is a hands‑on Senior Associate role—not a department-head position. You’ll help develop the firm’s in‑house billing capability with support from external consultants and experienced colleagues across Legal and Finance. The opportunity is to take meaningful ownership, learn the business, and grow—not to arrive with every answer or build everything independently.

Why consider this opportunity?

• A move into private equity without leaving your expertise behind. Apply your knowledge of legal billing, attorney relationships, and e‑billing workflows in an investment‑firm environment. Prior private equity experience is not required.
• A voice in how the work gets done. Help improve processes, reporting, and technology rather than simply inherit a narrowly defined billing assignment.
• Visibility and room to advance. Work directly with senior legal professionals and business partners across the firm, with potential to progress toward a manager‑level role as your contribution and the function develop.
• Compensation beyond base salary. The package includes an annual performance bonus, a substantial employer‑funded retirement contribution, comprehensive health benefits, paid parental leave, and a hybrid schedule.

What you’ll do

Keep legal billing moving. Coordinate a high volume of outside counsel invoices through review, approval, and payment follow‑up. Work with law firms, Legal, and Accounts Payable to resolve billing questions, coding issues, allocation discrepancies, and delays.

Support the systems behind the process. Maintain legal matter records and e‑billing workflows, including matter setup, coding, payment routing, and closure. Help users troubleshoot issues and coordinate with technology providers when needed.

Make legal spending easier to understand. Prepare reports covering legal spend, budgets, accruals, invoice status, and payments. Use Excel and billing data to identify trends, investigate exceptions, and provide clear information to Legal and Finance.

Help build a better function. Partner with internal colleagues and external resources to improve billing guidelines, vendor onboarding, data quality, controls, and reporting. Identify practical opportunities to reduce manual work and make processes more consistent.

What you’ll bring

• You have 3+ years of relevant experience, ideally in law‑firm billing, legal e‑billing, or an in‑house legal billing function. Related legal operations, accounts payable, accounting, or finance experience with meaningful billing responsibilities will also be considered.
• A bachelor’s degree is required; accounting, finance, business, or a related discipline is preferred. You should bring experience with legal e‑billing or matter management systems, strong Excel skills, and confidence working with detailed billing data.
• Just as important, you’re organized, proactive, and comfortable following an issue through to resolution. You can communicate effectively with attorneys, finance colleagues, and outside vendors while staying close to the details.
• You do not need to have managed a team or previously built an entire billing function. Strong billing fundamentals, sound judgment, curiosity, and a genuine interest in improving processes matter more than checking every box.
