Fullstack Engineer - Integrations (Freelance)

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.

Interview Process

• Manager interview + technical assignment (1h30)
• Fast offer cadence
