AI Lead Developer Experience

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.

Trusted by over 10,000 brands, Vibe.co reaches more than 120 million households across 500+ apps and channels, delivering an average 250% return on ad spend and 20% sales lift. 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.

Founded in 2022, Vibe.co is widely recognized as the category-defining platform in streaming TV advertising, bringing the power of Meta and Google-style performance marketing to the fastest-growing segment in media.

About The Role

You'll join our Engineering team, which owns the full technical stack powering Vibe's streaming TV advertising platform — from bidding infrastructure to data pipelines and the product engineers ship every day.

This role exists because we're making an AI-first bet on how engineers work. We believe the best engineering teams in the next year won't just use AI tools — they'll be built around them. We need someone to lead that shift at Vibe, and get there before anyone else does.

Three Reasons a Great Candidate Should Care

• Greenfield ownership. This is a new role. You'll define what developer experience means at Vibe — the tooling, the workflow, the culture around it.
• Real impact, fast. Every engineer at Vibe uses what you build. You'll feel the effect of your work within weeks, not quarters.
• A front-row seat to the product. You'll work closely with the product team, with direct visibility into how engineering decisions shape what Vibe ships.

What You'll Do

• Set the AI-first engineering standard: Define and roll out Vibe's AI-assisted development strategy across the engineering org. Own adoption of coding agents and AI tooling — Claude Code, Cursor, MCP — and drive measurable gains in engineering velocity. Identify where AI can remove friction and run experiments to prove it. Live at the bleeding edge of the AI tooling landscape, explore emerging best practices in this fast evolving space, and evangelize them internally.
• Own the developer tooling stack: Maintain and evolve Vibe's core developer tooling across GitHub, CI/CD, and local dev environments. Reduce time-to-first-commit for new engineers and time-to-ship for the whole team. Keep the stack lean — cut tools that don't pull their weight. Own the AI-centric golden path for Vibe’s software development lifecycle.
• Raise the security bar: Own security tooling and best practices across the engineering org. Embed security into the development workflow without slowing engineers down. Spot risks early and drive remediation before they become incidents.
• Measure and improve engineering efficiency: Define the metrics that matter for developer experience — and track them. Report on velocity, tooling adoption, and friction points to engineering leadership. Treat the engineering team as your customer; gather feedback and act on it.

What You Need

• Hands-on experience as a platform or developer experience engineer in a fast-moving product company.
• Deep familiarity with AI coding tools — you're using them seriously, not just dabbled.
• Proficiency in at least one of Go, Rust, or TypeScript — enough to understand the codebases you're improving.
• Experience owning developer tooling end-to-end: CI/CD, GitHub workflows, local dev environments.
• A track record of shipping improvements that engineers actually adopt.

Nice to Haves

• Experience in a high-growth startup where you had to build before you could scale.
• Exposure to security tooling and secure development practices.
• Familiarity with streaming TV, CTV, or ad infrastructure.

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.

• Hybrid flexibility: We're in the heart of Paris and our team is in 3x a week.
• Health insurance: Full coverage via Alan.
• Meal vouchers: Via Swile.

Our Interview Process

• Manager interview — Meet the person you'd work with directly.
• Take-home assignment + live debrief — A real problem, not a trick. We'll work through it together.
