Admin Assistant II

Interstates is looking for a proactive, organized Administrative Assistant II to help the Organizational Development (OD) team turn plans into coordinated, well-executed work.

Organizational Development helps strengthen how people and teams work, grow, and lead at Interstates. The team supports initiatives that develop employee capabilities, improve organizational effectiveness, and help the company achieve its goals.

This role goes beyond routine administrative support. You’ll coordinate projects and programs, prepare meetings and trainings, develop first drafts of communications and presentations, and track details from planning through follow-up. You’ll work with the OD team to keep priorities visible, action items moving, and materials ready when they’re needed.

What You’ll Do

Coordinate OD projects and initiatives from planning through follow-up, organizing timelines, next steps, and key details.

Track deadlines, action items, and dependencies; flag upcoming needs or potential roadblocks.

Coordinate meetings, trainings, and workshops, including agendas, materials, logistics, notes, and follow-up.

Prepare first drafts of presentations, documents, communications, and meeting materials for review.

Maintain accurate project information, schedules, documentation, and records.

Handle sensitive information with professionalism and discretion.

Adapt as priorities change while maintaining accuracy and dependable follow-through.

What You’ll Bring

Strong project coordination and organizational skills, including the ability to manage multiple priorities.

Initiative and sound judgment; you can get started, ask useful questions, and anticipate next steps.

Excellent written and verbal communication skills, including the ability to prepare polished drafts and presentations.

Adaptability, attention to detail, and confidence learning new systems.

A strong understanding of Microsoft Outlook, Word, Excel, PowerPoint, and Teams

Professionalism, discretion, and a collaborative approach.

2–3 years of administrative, office support, or project coordination experience preferred.

What Success Looks Like

You create clarity and help work move forward. You organize details, communicate timely updates, surface potential issues, and follow through without needing every step spelled out. You’re comfortable coordinating work across people and priorities—and take pride in helping the team deliver on its commitments.
