• Own enterprise integrations across authentication, OAuth, webhooks, data syncs, backfills, rate limits, retries, monitoring, and production support.
• Take features from technical design through implementation, deployment, monitoring, customer feedback, and iteration.
• Work with customers to understand their systems, diagnose failures, and turn specific needs into reusable product capabilities.

WHAT WE'RE LOOKING FOR

• Three to six years of experience as a backend-leaning full-stack software engineer, with substantial backend ownership.
• Experience building production systems for enterprise customers, including data models, pipelines or queues, and integrations.
• Comfort shipping user-facing features with TypeScript and React; Python experience is preferred.
• Familiarity with relational and vector databases and cloud environments.
• A bachelor's degree in computer science or a related field.
• Experience with AI agents, LLMs, evaluation, or quality assurance is beneficial.
• US work authorization is required. The role does not provide visa sponsorship or visa transfer.
