About the role

Key responsibilities & impact

Design and implement integrations with external platforms, CRMs, CDPs, measurement vendors, and data partners
Own integration projects end-to-end, from scoping to production with minimal hand-holding
Collaborate directly with external partners to define and validate data contracts
Build the infrastructure for Vibe's public API, account, advertiser, and campaign management endpoints
Develop documentation, monitoring, and tooling that makes the developer experience first-class
Contribute to MCP gateway and authentication layers that expose Vibe's capabilities externally
Identify bottlenecks in existing pipelines and rebuild them to handle growing data volume
Write code that your team can review, extend, and trust, not just code that ships
Use AI tooling actively to accelerate development and close quality gaps

Requirements

What you’ll need

Hands-on experience shipping production-grade software in TypeScript and Python, you've written it, debugged it, owned it
Comfort working across the full stack: APIs, data pipelines, and infrastructure (AWS, Terraform)
Exposure to low-level programming concepts, C or C++ experience is a plus; knowing how memory and concurrency actually work is the bar
A startup or high-ownership background, you've operated without a team for every problem and figured things out
Strong instincts for code quality: you give real feedback in reviews and can receive it the same way
Prior experience building or maintaining third-party integrations (ETL, webhooks, REST/GraphQL APIs) is nice to have
Familiarity with GCP or multi-cloud environments is nice to have
Experience designing or contributing to developer-facing platforms or public APIs is nice to have
