About Prelude
Prelude is redefining how companies authenticate and onboard users - turning what's traditionally a cost center into a growth lever.
Our flagship product lets businesses send OTP codes with the best price-to-conversion ratio on the market, dynamically selecting the most effective channel in real time (optimized SMS, WhatsApp, and more) while actively blocking spam and fraud that legacy providers miss.
Founded in 2022 by former Zenly team members who lived the pain of broken SMS authentication firsthand, we're already serving fast-growing companies across Europe and are expanding into the US.
But authentication is only the starting point - we're building the platform for trust at scale, with an ambitious roadmap of market-defining products ahead.
Why join us
Today, we're a team of 60 and growing, based in Paris, building products that power secure and high-performance user onboarding for companies across the world. We believe small, highly skilled teams outperform large, fragmented organizations, and we are intentional about staying focused on impact, quality, and speed.
We operate with a flat org structure and value in-person collaboration, which helps ideas move faster, decisions stay grounded, and teams take full ownership of what they build.
Our values
Care
We care deeply about our customers, our teammates, and the quality and reliability of what we ship.
Bias for Action
We move fast, test in the real world, and iterate quickly rather than over-optimizing in theory.
Ownership
We take responsibility end to end, from identifying problems to delivering outcomes and learning from results.
About the role
We’re hiring our first dedicated Brand Marketer - there’s no playbook yet, and as the first hire in this position you'll be the one writing it! You’ll own how Prelude presents itself to the world - brand voice, social presence, content, events, PR - all of the work that turns curious developers and founders into customers. You'll also represent the company externally across different audiences.
This is a hands-on role with a lot of autonomy, working directly with the founders and partnering closely with engineering, design, and sales. This position reports into our co-founder and CEO, Matias, and works closely with our Marketing Manager - who will own performance marketing and SEO.
What will you do?
Frame our positioning and messaging, outlining Prelude's tone of voice and identity
Own Prelude's voice (including the Founders) across LinkedIn, X, Hacker News and other sites
Turn product launches, customer wins, and industry moments into on-brand posts (the more personality the better), owning our content calendar and shipping consistently
Run weekly experiments - posts, threads, replies, comments - and iterate based on what lands
Partner with design to develop the site, decks, ads, and swag
Pitch Prelude as a speaker to priority events as well as international media across business, but also newsletters and influencers.
Own our events strategy and organisation end to end: founder dinners, hackathons, developer conferences, tracking ROI and reporting on outcomes
Set goals with the founders and report on them weekly, bringing a commercial mindset to every channel decision
Use AI tools to scale output - editing agents, asset generation, and whatever else makes sense
What are we looking for?
Experience in brand, growth, or content marketing - ideally from B2B SaaS but we’re open minded and happy to consider candidates from B2C or agency
Strong writing instincts across different formats - short-form social, long-form editorial, email, and event copy
Budget ownership and management
Confidence speaking publicly and building media relationships, representing Prelude externally
Experience planning and running events people actually remember
A genuine interest in developer-first products - you need to talk credibly to engineers and founders
Operator energy, getting things done without waiting for permission
Confidence using AI tools to increase your output
Knowledge of or enthusiasm to learn about security, authentication, or infrastructure
A portfolio that proves it (social accounts you’ve grown, events you’ve made memorable)
