About Vibe

At Vibe.co, we're reimagining how brands reach audiences in the age of streaming. We believe streaming TV is no longer just a brand awareness play, it's the next great performance marketing channel. We're building the infrastructure to unlock this $100B opportunity.

Vibe.co provides an Audience First Streaming TV Advertising solution for marketers to unlock TV as a growth channel. Our all-in-one solution combines hyper-targeted audience segmentation, AI-powered insights and recommendations, real-time campaign optimization, and incrementality measurement, giving brands of all sizes the precision and transparency they've come to expect from social and search, but on TV.

The company hit a $100 million revenue run rate in under two years, ranking among the ten fastest software companies to reach that milestone.

Vibe.co's investors include Hedosophia (an early backer of Spotify, Uber, and Airbnb), Elaia, Singular, QuantumLight (Revolut CEO Nik Storonsky's fund), and Illusian (Supercell CEO Ilkka Paananen's fund), as well as angel investors including Carolyn Everson, board member of The Walt Disney Company and Coca-Cola. Nirav Tolia, CEO of Nextdoor, sits on the company's board of directors.

About the Role

You'll join the AdManager team, the team behind Vibe's client-facing advertiser experience. The team helps advertisers set up campaigns, understand performance, manage creatives, connect tools and data sources, handle payments, and manage their investment through a seamless, reliable interface.

This freelance role exists because AdManager's scope is growing fast, and we need senior engineering capacity to keep shipping complex advertiser-facing initiatives without lowering the bar on product quality, reliability, and maintainability. This is not a narrow execution role. You'll own meaningful work end-to-end: from problem definition, technical design, dependency management, and development through rollout, monitoring, production follow-up, and continuous improvement.

3 reasons to want this role:

• You'll work on a high-impact product surface used directly by advertisers

• You'll collaborate with a strong engineering and product team operating with high ownership and low process friction

• You'll work in an AI-forward environment where speed, technical excellence, and product judgment are expected to reinforce each other.

What You'll Do

Build & Ship Advertiser-Facing Product

• Design, build, and evolve core AdManager features across campaign setup, reporting, onboarding, creatives management, payments, account management, and AI-powered workflows

• Own complex initiatives from conception to production with minimal supervision

• Translate ambiguous product needs into clear technical plans, milestones, and production-ready features

• Collaborate closely with product managers, engineers, and business stakeholders to deliver high-quality advertiser experiences

Fullstack Engineering

• Build and maintain robust user-facing experiences using Next.js, React and Typescript

• Design scalable APIs, services, database schemas, and domain models that remain maintainable as the platform grows

• Work with PostgreSQL and backend systems to support reliable advertiser workflows and reporting experiences

• Apply strong engineering practices, including testing, clear architecture, and thoughtful code reviews

Reliability & Production Ownership

• Ship features with appropriate monitoring, logging, alerting, analytics, and observability

• Investigate, debug, and resolve production issues for the systems you build

• Contribute to incident response and postmortems with clear communication and ownership

• Improve codebase maintainability, documentation, conventions, and developer experience beyond your assigned tickets

Product & Technical Judgment

• Understand advertiser workflows and proactively identify better product or technical solutions

• Challenge weak assumptions and propose pragmatic alternatives that balance speed, business impact, and long-term quality

• Use AI-assisted development workflows to accelerate delivery while maintaining a high bar for correctness and maintainability

• Contribute positively to a shared codebase and a collaborative, low-ego engineering culture

What You Need

• Strong experience shipping production-grade fullstack software, especially with Next.js, React, Typescript, backend APIs, and PostgreSQL

• Proven ability to own projects end-to-end, from problem definition to rollout, monitoring, and long-term maintenance

• Strong backend engineering fundamentals: API design, architecture, testing, data modeling, and system design

• Ability to independently build and evolve complex user-facing experiences

• Comfort operating in ambiguity, breaking down initiatives, identifying dependencies, managing risks, and keeping delivery momentum

• Strong instincts for code quality, maintainability, and pragmatic technical decision-making

• Experience taking responsibility for production systems, including monitoring, debugging, incident response, and postmortems

• A collaborative, low-ego mindset and clear communication style, especially during project delivery and production issues

• A strong sense of urgency, with the judgment to move fast without sacrificing reliability or long-term maintainability

Nice to Haves

• Experience in AdTech, campaign management, reporting, CTV, or customer-facing SaaS products

• Familiarity with Domain-Driven Design and Test-Driven Development practices

• Experience with AI-powered products or AI-assisted development workflows

• Experience improving developer experience, codebase conventions, internal tooling, or shared engineering practices

• Prior exposure to advertiser workflows, campaign performance, creative management, or media buying platforms

What Success Looks Like

After 90 days, you are a fully integrated member of the AdManager team. You understand the team's architecture, scope, advertiser workflows, and the basics of the CTV ecosystem. You can independently own meaningful features from conception to production, ship with the expected level of quality and observability, and contribute improvements to the codebase beyond feature delivery.

You are trusted not only to write strong code, but to make good product and technical decisions, communicate clearly, handle ambiguity, and take real ownership of the systems you build.

Our Values

At Vibe, we run on three values: Impact, Ambition, and Urgency. We tie every goal to a real business outcome, think 10x rather than settling for good enough, and move daily rather than waiting for perfect conditions.

You'll thrive here if you own outcomes without needing direction, default to action, and hold yourself to results, not effort.

This is a high-performance environment with high-performance rewards: you'll work alongside people who push you, with real ownership over hard problems in a market that's moving fast.

If that sounds like the best version of your career, we want to meet you.

What We Offer

• Hybrid flexibility — We're in the heart of Paris.

• Annual offsite — The whole team, once a year, somewhere worth the trip.

• Tech Syncs — Engineering and Product meet in person at least quarterly, worldwide.

Our Interview Process

We respect your time. Here's exactly what to expect — no surprises, no ghosting.

1. Recruiter screen — 30 min. We'll share context; you'll share yours.
