About the Role We’re looking for a Social Media Manager to own our presence on LinkedIn, Instagram, and TikTok. Strategy, creation, production, publishing, community. All of it. This role is part of Plus Company and Cossette’s marketing and communications team. You’ll build serialized formats that give senior marketers a reason to pay attention, use each platform to drive different outcomes, and know when a trend is built for us and when to pass. This is a highly cross‑functional role working closely with Cossette’s social strategists, creative, strategy, and new business teams to tell the Cossette story in ways that actually land. You’ll be on camera, move fast, and agency experience helps.
You’ll be expected to deliver content that energizes, engages, and converts audiences across our three platforms while keeping each platform’s unique purpose and voice in mind.
Responsibilities Own Cossette’s LinkedIn, Instagram, and TikTok end‑to‑end: strategy, content calendar, production, publishing, community management, and reporting.
Concept and create original content across all three platforms, with a strong instinct for what works where and why.
Build and own a content calendar, organizing production details with minimal support and managing approval processes.
Build and run serialized content formats: recurring series that give people a reason to come back.
Use social to drive different outcomes per platform—LinkedIn for leads and thought leadership, Instagram and TikTok for brand and culture.
Make the call on trends. Know when Cossette should jump in and when to stay on the sidelines, with clear reasoning.
Appear on camera when the content requires it. It will often call for it.




Encourage other team members to appear on camera.
Track performance and use data to sharpen what we’re making. Test and learn is key.
Partner with internal teams to amplify agency work, wins, and culture.
Experience driving leads on social—especially on LinkedIn—is a plus.
Familiarity with paid media on social platforms is also a plus.
Qualifications 3+ years of social media experience, agency‑side or with a brand that moves like one.
A portfolio or reel that shows range: writing, video, editing, strategy. Show us the whole picture.
Proficiency in Adobe Premiere or a strong mobile‑first editing workflow (e.g., CapCut). After Effects is a bonus.
Confident on camera.
Deep platform fluency across LinkedIn, Instagram, and TikTok—understand why they work.
Strong writing skills: captions, concepts, briefs, reports. All must land.
Sharp filter for trends: you know which ones are built for Cossette and which aren’t.
Self‑starter. You don’t wait to be told what to post; you already have three ideas.
Organized and detail oriented.
Ad agency experience is a real advantage—understanding creative culture, client work, and storytelling that makes agencies stand out.
Benefits An innovative and entrepreneurial work environment that promotes ingenuity and individuality.
Hybrid work models and flexible hours,



plus a work‑from‑anywhere policy for short‑term stays in other regions.
Generous vacation starting at 3 weeks + 1 extra week over the holidays.
Agency summer days (exact policy differs per campus and agency).
Modern, open co‑working spaces with coffee & snack bars, located in excellent city neighborhoods near shops, restaurants, and public transport.
Dogs allowed, dedicated play room to support families, and private wellness room (in select offices).
Team social events—holiday parties, seasonal gatherings, weekly happy hours, inspiring speakers, and more.
Learning & Development In‑house learning & development sessions and annual career and growth conversations.
Access to internal network of opportunities across all agencies.
Focus on developing BIMPOC talent via our BIMPOC Mentorship Program.
Internal EDI group(s), programs & initiatives across Plus Company and opportunities to be involved in employee resource group(s).
EEO Statement We are an equal opportunity employer and do not discriminate based on age, colour, ability, national origin, race, religion, sex, or sexual orientation. Embracing difference is what makes Cossette what it is—and we wouldn’t have it any other way. We pride ourselves on an inclusive and accessible workplace. If you need any accommodations during the interview process to make it work for you, let us know.
