We empower agencies and businesses to create, schedule, and manage posts across multiple platforms, while also providing automation, analytics, and engagement tools. Our primary objectives are to drive Social Planner adoption, improve feature retention, and maximize user engagement by making social publishing effortless and impactful. We are responsible for: Post Publishing & Scheduling We enable agencies to publish and schedule posts across major social platforms, ensuring timely and consistent content delivery. Post Automation We support advanced publishing workflows, including CSV uploads, RSS-to-post, Review Posts, Category Queues, and Recurring Queues—giving agencies full flexibility to manage content at scale. Engagement & Insights Through Social Statistics, Comment Management, and Social Listening, we provide agencies with deep insights into performance and engagement, enabling data-driven content strategies. Best Time to Post We surface AI-driven recommendations on when to post for maximum reach and engagement, helping agencies optimize their content strategy. Multi-Platform Integration We currently support integrations with 9 major platforms—Google Business Profile, Facebook, Instagram, LinkedIn, TikTok, YouTube, Pinterest, Threads, and Bluesky—along with HighLevel’s internal Community product. About the Role: Millions of businesses post to social media through HighLevel's Social Planner. Hundreds of thousands of posts go out every day across every major social platform, each with its own API, rate limits and frequent changes. Our job is to make that look easy. We're a small team with a big surface area, and we're building the next layer on top of publishing: understanding what the internet is saying about our customers, at scale, with AI. We're hiring a senior full stack engineer who wants to own that. EEO Statement: The company is an Equal Opportunity Employer.
