Senior Backend Engineer, Integrations

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 the Integrations team, the connective tissue of Vibe's platform, reporting directly to the Engineering Manager. The team owns all data flowing in and out of Vibe: measurement and attribution integrations, audience connections from CRMs and CDPs, and reporting pipelines. This role exists because we're building a first-class Developer Platform, opening Vibe's full capabilities as an API so external partners can build on top of us. Three reasons to want this: you'll be a senior voice on a team that operates at the center of Vibe's growth, you'll own foundational architecture decisions on a platform that marquee partners like Clay are already building against, and you'll work in an environment where AI-augmented development is the expectation, not the experiment.

What You'll Do

Build and Ship Integrations

• Design and implement production-grade integrations with external platforms: CRMs, CDPs, measurement vendors, and data partners

• Own integration projects end-to-end, from scoping through production, with full accountability for outcomes

• Collaborate directly with external partners to define, validate, and evolve data contracts

Developer Platform

• Drive the architecture of Vibe's public API: account, advertiser, and campaign management endpoints built to scale

• Develop documentation, monitoring, and tooling that makes the developer experience genuinely first-class

• Contribute to MCP gateway and authentication layers that expose Vibe's capabilities to the world

Reliability and Scale

• Identify architectural weaknesses in existing pipelines and lead the effort to rebuild them for scale

• Set the standard for code quality on the team. Your reviews move the bar, not just the diff

• Use AI tooling actively to accelerate development and raise output quality across the team

Team Leadership

• Mentor junior and mid-level engineers through code review, pairing, and direct feedback

• Help establish engineering norms and practices as the team scales across two continents

• Partner with the Engineering Manager on technical direction and hiring calibration

What You Need

• Typically 6+ years shipping production backend systems: APIs, data pipelines, and distributed services at scale

• Deep hands-on proficiency in TypeScript and Python; you've owned complex systems in both, not just contributed to them

• Strong infrastructure fundamentals: AWS, Terraform, and the judgment to make architectural decisions, not just implement them

• Exposure to low-level programming concepts. C or C++ background is a plus; you understand what's happening beneath the abstraction

• A high-ownership background: startups, scale-ups, or any environment where you couldn't hand the hard problems to someone else

• A track record of raising the quality of the engineers around you, not just your own output

Nice to Haves

• Prior experience building or maintaining third-party integrations (ETL, webhooks, REST/GraphQL APIs)

• Familiarity with GCP or multi-cloud environments

• Experience designing or contributing to developer-facing platforms or public APIs

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

At Vibe, we want you to build something, own something, and grow fast. Here's how we back that up:

• Equity. Employee Stock Ownership Plan. You're building this; you should own part of it.

• Variable pay based on objectives you hit. No arbitrary targets.

• 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.

• 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.

2. Manager interview. 30 min with your future manager. Your experience, your projects, your approach.

3. Technical assessment. 90 min. Code review exercise plus applied questions, including how you use AI in your workflow. Real problems, not tricks.

4. Bar raiser. 30 min with a senior leader to ensure we're holding a consistent, high bar.

5. Offer. Fast. We don't let good decisions sit.
