Full job description

Edelman is a voice synonymous with trust, reimagining a future where the currency of communication is action. Our culture thrives on three promises: boldness is possibility, empathy is progress, and curiosity is momentum.

At Edelman, we understand diversity, equity, inclusion and belonging (DEIB) transform our colleagues, our company, our clients, and our communities. We are in relentless pursuit of an equitable and inspiring workplace that is respectful of all, reflects and represents the world in which we live, and fosters trust, collaboration and belonging.

Edelman Canada is looking for a social-obsessed Senior Copywriter to join its creative department, led by Anthony Chelvanathan, CCO and Global Creative Partner to the one and only Judy John. Beyond the obvious—a chance to learn from the best—the role offers the opportunity to work on globally recognized brands with the team that won the country’s first PR Gold at Cannes at an agency consistently ranked one of Canada’s best places to work.

The role includes a mix of Canadian and US clients who want to win in culture by dominating social feeds and conversation. But this isn’t about adapting big campaign ideas into social—it’s about building them from culture. We’re looking for a writer who understands how ideas take shape in feeds, comment sections, and creator ecosystems. Someone who knows how to turn a trend into a brand moment, a reaction into a narrative, and a post into participation. This is social-first thinking in its truest form: fast, fluent, and rooted in what people actually care about right now.

Edelman is a global communications firm built for a digital world. With over 70 years of building trust and earning attention, we help brands create direct, meaningful connections with audiences by crafting magnetic stories that move at the speed of social, shape culture, and spark movements.

Our creative teams are behind some of the world’s most talked-about work—not because we chase culture, but because we understand how to show up inside it. From tapping into BookTok with Hellmann’s Garlic Aioli to turn a product into a plot twist, to flipping dupe culture on its head with Lululemon, to meeting fans where they already are with Knorr at FlavourMania for a flavourful smackdown—we build ideas that start with real behaviours and real communities. The result? Work that invites participation, earns engagement, and creates genuine connections between brands and the people who love them. Around here, briefs don’t ask for relevance—they demand ideas that people want to be part of.

What does that look like day-to-day? It’s not a standard brief, and definitely not a standard output. You might start your morning writing a brand anthem, spend your afternoon concepting a culture-hijacking stunt, and wrap the day crafting reactive content that hits while the moment’s still hot. The common thread: ideas designed to earn attention, spark conversation, and travel.

If you’re the kind of writer whose references come as much from TikTok comments as they do from award winning campaigns, and you’re hungry to make work that people actually want to engage with, you’ll be in the right place.

Sound like something you'd get excited about? Scroll on.

What You’ll Do:

Create social-first ideas from brief to execution—individually and in partnership with art directors, strategists, and creators across North America.
Translate cultural trends, platform behaviours, and audience nuances into sharp, relevant creative opportunities
Concept proactive ideas, always-on brand assets and campaign work that lives natively across platforms (TikTok, Instagram, X, Reddit, etc.)
Collaborate across disciplines including strategy, account, project management, and influencer/creator teams
Partner with creators and understand how to co-create, not just brief them
Lead by example—pushing for ideas that are culturally relevant, not just creatively “good”
Bring a strong POV on tone, voice, and brand presence in social ecosystems

Who We Want:

A copywriter with a social-first brain (not just a traditional one adapting to social)
6+ years in advertising, PR, or content, with a portfolio that proves you understand how brands show up in culture
Deep understanding of social platforms, formats, and behaviours—not just what works, but why
Someone who is tapped in online and has a sharp instinct for trends, communities, and conversations
Experience working with creators or influencer-led campaigns is a strong asset
An entrepreneurial mindset—fast, responsive, and comfortable with real-time content creation that asks for agility over perfection
Strong conceptual thinking paired with the ability to write across formats: from punchy captions to scripts to comment comebacks
Curious, collaborative, ego-free, and obsessed with ideas that people actually care about

If your best work doesn’t feel like an ad, and your references are just as likely to come from TikTok comments as they are from Cannes case studies, we should talk.

#LI-KG1

We are dedicated to building a diverse, inclusive, and authentic workplace, so if you’re excited about this role but your experience doesn’t perfectly align with every qualification, we encourage you to apply anyway. You may be just the right candidate for this or other roles.
