Social Media Marketing Internship in Milwaukee, Wisconsin at Sigma Commercial LLC

Social Media Marketing Internship — Sigma Commercial LLC
Location: Milwaukee, WI (East Side) — On-site
Employment Type: Full-Time, Internship (3 months)

About Us
Sigma Commercial LLC is a Milwaukee-based holding company overseeing four operating businesses: LaBonte Construction (luxury residential remodeling), Property Prep (commercial maintenance and janitorial), Vandelay Group (residential property management), and Sigma Commercial itself (shared back office). We're a small, hands-on team - people wear multiple hats and things get done without a lot of red tape.

The Role
We're looking for a Social Media Marketing Intern to build and run our social presence across three brands: Property Prep LLC, LaBonte Construction LLC, and our CEO's personal brand. We have strong video and podcast content already being produced in-house - we just don't distribute it well. You'll own fixing that: turning existing assets into platform-native content and building a real posting cadence across Facebook, Instagram, LinkedIn, and web.

Key Responsibilities
• Develop and execute a social media content plan for Property Prep LLC, LaBonte Construction LLC, and the CEO's personal brand
• Manage and grow presence across Facebook, Instagram, LinkedIn, and web/website content
• Repurpose existing assets from our YouTube channels and podcast into platform-native content: clips, quote graphics, carousels, reels, and similar formats
• Design graphics and short-form visual content using Adobe Creative Suite and Canva
• Support basic updates and content additions to WordPress-based websites
• Collaborate directly with our in-house video and audio team to scope and request new assets as needed
• Maintain a consistent posting calendar across all three brands and four platforms
• Track basic performance metrics (engagement, follower growth, reach) and adjust the plan based on what's working
• Keep brand voice and messaging distinct and appropriate across Property Prep, LaBonte Construction, and the personal brand

What We're Looking For
• Currently pursuing or recently completed a degree in marketing, communications, digital media, or a related field
• Working knowledge of Adobe Creative Suite (Photoshop, Premiere, or similar) for graphics and content editing
• Proficiency with Canva for fast-turnaround social and marketing graphics
• Familiarity with WordPress for basic website updates a plus
• Genuine familiarity with Facebook, Instagram, and LinkedIn from a business/brand management perspective, not just personal use
• Strong writing skills and an eye for what makes content stop the scroll
• Self-starter who can manage multiple brand voices and platforms without constant oversight
• Comfortable proposing a plan and defending it, not just waiting for direction

What You'll Gain
• Real ownership over three distinct brand presences, not busywork
• Direct collaboration with a professional video/audio production team
• Portfolio-ready work: campaigns, growth metrics, and content you can point to after the internship ends
• Exposure to how a multi-brand company approaches marketing across construction, property management, and personal branding

Compensation & Logistics
• $16.00/hour, full-time (40 hrs/week)
• 3-month duration, in-person at our Milwaukee East Side office, with potential to extend or convert based on performance
