Backend Software Engineer (Python / Go)
About the role
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. This is a full-time backend role based in our Warsaw office or remote within Poland, reporting to the Engineering Manager.
In this role, you’ll get to:
•
Build and maintain integrations with social platform APIs, including Instagram, TikTok, YouTube and others.
•
Develop backend services in Python and Go.
•
Work on streaming data pipelines using Kafka and AWS.
•
Modernize legacy services and improve performance.
•
Support production by handling alerts and investigating data issues.
•
Build AI agents and tools (LLM-based agents, MCP servers) that automate engineering and support work, such as data triage.
•
Use AI across the whole development lifecycle: design, coding, testing, code review and operations.
•
Collaborate with Product, Data and other engineering teams.
