Backend Software Engineer (Python / Go)
Employment Type: Full time Employment ContractAs a Software Engineer on the Social Integrations (Social API) team, you’ll build the backend services and streaming pipelines that pull creator content, metrics and audience data from Instagram, Facebook, TikTok, YouTube, X, Snapchat, Pinterest, Twitch and third-party data providers. You’ll turn that data into reliable foundations for campaign reporting, community, discovery and earned media value (EMV) across CreatorIQ, at a scale of roughly 1 billion social records per day. Upstream APIs change without notice, throttle traffic and fail in creative ways, so you’ll design for resilience, token health and monitoring from day one.

•
Build and maintain integrations with social platform APIs, including Instagram, TikTok, YouTube and others.
