Fullstack Engineer - Integrations (Freelance)
Uses AI tooling and AI-augmented development; focused on building developer-facing APIs and integrations that enable rapid partner integration.
About the Role
Build and ship integrations and a developer platform to connect external CRMs, CDPs, measurement vendors, and data partners to Vibe's streaming TV advertising platform, owning projects end-to-end and improving reliability and scale using TypeScript, Python, and cloud infrastructure.
Job Description
Role
Join the Integrations team to design, build, and operate integrations and the developer-facing platform that exposes Vibe’s capabilities as public APIs. You’ll own integration projects end-to-end, collaborate directly with external partners to define data contracts, and contribute to authentication and gateway layers.
Key Responsibilities
- Design and implement integrations with external platforms, CRMs, CDPs, measurement vendors, and data partners.
- Own integration projects from scoping through production with minimal hand-holding.
- Build infrastructure for Vibe’s public API, including account, advertiser, and campaign management endpoints.
- Develop documentation, monitoring, and tooling to improve the developer experience.
- Contribute to gateway and authentication layers that expose Vibe’s capabilities externally.
- Identify and remove bottlenecks in pipelines to improve reliability and scale.
- Write maintainable, reviewable code and use AI tooling to accelerate development and improve quality.
Requirements
- Hands-on experience shipping production-grade software in TypeScript and Python.
- Comfortable across the full stack: APIs, data pipelines, and infrastructure (AWS, Terraform).
- Exposure to low-level programming concepts; C or C++ experience is a plus.
- Startup or high-ownership experience, able to operate independently and take full ownership of problems.
- Strong instincts for code quality and active participation in code reviews.
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.
Values & Working Style
Vibe emphasizes Impact, Ambition, and Urgency. The company expects ownership of outcomes, fast iteration, and a results-oriented approach. This is a high-performance environment with significant responsibility and rapid decision-making.
Location & Logistics
Role operates with hybrid flexibility; the company notes an in-office presence in Paris (team meets ~3x/week) and describes the Integrations team growth in New York. The position is freelance/contract in nature. Engineering and product teams meet in person quarterly; there is an annual company offsite.
