Senior Backend Engineer, Integrations

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., * 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, * Manager interview. 30 min with your future manager. Your experience, your projects, your approach.
• Technical assessment. 90 min. Code review exercise plus applied questions, including how you use AI in your workflow. Real problems, not tricks.
• Bar raiser. 30 min with a senior leader to ensure we're holding a consistent, high bar.
• Offer. Fast. We don't let good decisions sit.

• 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, * 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
