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.
