Brand & Communications Lead

Generic AI averages the internet. Onix lets you summon the actual judgment of a health and wellness expert who has spent a career on your problem, private and personal: names already live on the App Store include Dave Rabin, Mark Sisson, Ashley Koff, William Li, and Elissa Epel .We need someone who owns that story everywhere it reaches a person: the App Store listing, social, press, every launch. This is the difference between someone scrolling past and someone who stops, downloads, and trusts Onix with something that actually matters to them.You are a writer first: someone who can point to work that changed how people understood something, and say why it worked. You protect that voice everywhere someone finds us, and you build the work yourself, in person, from our office in Old Montreal.What You Will Do
Copy.
Write and set the standard for every word Onix says, from social and the website to the App Store listing and the newsletter.Storytelling.
Turn the company story, the expert stories, and every launch and press moment into a message a person actually feels.Brand.
Own the argument for why Onix is different from Big AI, and keep that voice whole across every expert, a fast-shipping product team, and a founder-led feed.Creative production.
Ship the assets, post creative, video cuts, campaign pieces, applying the visual system design owns and building things yourself when speed matters.Events and PR.
Run our presence at conferences and expert-led gatherings, keep our PR firm equipped to pitch well, and dream up the ideas creative enough to cut through Big AI’s noise.Who You Are
A consumer marketing background, ideally health, wellness, or an adjacent lifestyle category.Shipped content in a real market: UGC, video, copywriting, and storytelling that moved someone, not just made something.Range across strategy and execution: you set the direction and still write the caption yourself. This is not an entry-level role.Comfortable in a high-velocity environment, with the grit, tenacity, and initiative to see a bold idea through. You are in it for the mission.This Role is NOT For You If:
You want a remote job. We build together in person, in Old Montreal.You want to direct writers and designers rather than write and produce the work yourself.You come from a B2B or pure enterprise background.What Success Looks Like
The App Store listing, the website, and the social feed read as one voice.People can say what Onix is after one sentence from us, and they use our words to say it.A campaign or moment you shaped gets people talking about Onix instead of scrolling past it.The brand guidelines stay current, and the team uses them without being asked.Our owned channels grow on a metric you defined and can defend.A critique of how we communicate, and how you would make it better.A portfolio of your past work, especially your content and your writing.Onix launches Tiny Labs, a Montréal research group building small language models around one expert, to keep their knowledge, judgment, and voice intact.Nathalie Niddam lost a 36,000-person community to Meta, then her Instagram account. She talks to Onix founder David S. Bennahum about owning what you know.Registered dietitian Ashley Koff answers six questions she hears most often, on GLP-1 stalls, fiber, protein, bone health, and fasting.BetaKit covers Onix's $5M USD pre-seed raise: small models, on-device privacy, and why the founders are building in Montréal.
