Social Media Automation Developer - Cloud Phones API - Multi-Account Warmup, Posting & Control

We are looking for a senior specialist with proven experience using cloud-phone APIs to automate social media account operations across Facebook, Instagram, TikTok, and Threads. This is not a general automation role. You must have previously worked with cloud phones through an API, implemented social media automations, and understand account warmup, account quality, operational consistency, posting workflows, and account-health monitoring. Please do not apply if your experience is limited to: • Generic API integrations • Basic social media schedulers • Zapier, Make.com, or n8n workflows • Marketing or manual social media management • Automation testing without production social media automation • Theoretical knowledge of cloud phones without hands-on API experience You will work alongside our existing engineering team. Our team can handle parts of the backend, dashboard, database, infrastructure, queues, and analytics. We need a domain expert who can guide and implement the cloud-phone and social media automation components while collaborating closely with our developers. What We Are Building A centralized system for managing authorized social media accounts using cloud-phone providers such as: • GeeLark • DuoPlus • VMOS Cloud • BitCloudPhone • Similar API-enabled cloud-phone platforms The system will initially manage approximately 100 accounts, with an architecture capable of expanding to thousands of accounts across multiple providers and machines. Your Role You will help our team design, implement, and validate: • Cloud-phone provider API integrations • Social media automation workflows • Progressive account warmup schedules • Posting and content-distribution workflows • Account-health and quality monitoring • Stable account-to-device environment assignments • Workflow pacing, cooldowns, limits, and failure handling • Operational strategies for maintaining account quality • Performance monitoring and organic reach analysis The exact division of work will depend on your strengths. You will not be expected to build every dashboard, backend service, or infrastructure component alone. Cloud-Phone Automation You should understand how to: • Authenticate with cloud-phone provider APIs • Import, create, start, stop, reboot, and monitor profiles • Retrieve device and profile status • Assign accounts to specific cloud-phone environments • Manage application and device workflows • Coordinate concurrent and sequential device sessions • Detect offline, unavailable, or unhealthy environments • Build a shared provider interface for multiple cloud-phone services • Handle API limits, failures, retries, and provider-specific behavior Social Media Automation You should have practical experience automating operations on one or more of these platforms: • Facebook • Instagram • TikTok • Threads Relevant workflows include: • Account onboarding • Progressive warmup • Scheduled posting • Image and video publishing • Caption and content-pool assignment • Account-specific schedules • Workflow pauses and cooldowns • Execution verification • Failure detection and recovery • Activity and account-status logging Warmup and Account Health We specifically need someone familiar with account warmup and account lifecycle management. You should be able to advise on and implement: • Warmup stages based on account age and condition • Gradual activity schedules • Platform-specific pacing and limits • Daily operating windows and cooldown periods • Account-health scoring • Detection of login, session, posting, or verification problems • Detection of restrictions, removals, or abnormal performance changes • Automatic pausing of unhealthy accounts • Recovery and reactivation workflows • Consistent account, device, region, language, timezone, and network assignments • Prevention of accidental cross-account activity Posting and Performance The system will manage content and posting across groups of accounts. Relevant functionality includes: • Images, videos, Reels, short-form videos, and captions • Content and caption pools • Scheduling by account, platform, timezone, niche, and campaign • Reliable retries without duplicate posting • Post status, URL, ID, timestamp, and error tracking • Views, reach, watch time, engagement, and posting-frequency analytics • Testing content formats, hooks, captions, and posting times • Identifying content patterns associated with stronger organic distribution • Detecting declining account or content performance Our team can build supporting dashboards and analytics infrastructure. We need you to help define the correct signals and automation behavior. Required Experience • Previous cloud-phone API integration experience • Previous social media automation experience • Practical understanding of account warmup and account health • Experience with GeeLark, DuoPlus, VMOS Cloud, BitCloudPhone, or a comparable provider • Strong API integration and scripting experience • Ability to work inside an existing team and codebase • Ability to document provider behavior and automation workflows • Experience designing reliable retries, limits, scheduling, and logging Backend experience with Node.js, TypeScript, JavaScript, or Python is valuable, but proven domain experience matters more than a specific language.
