What is HeyMark?
Mark is an AI-powered digital marketing agent that replaces agencies. You talk to him, and he does everything. Analyzes your metrics, generates strategy, creates visual content and video, automates DMs, manages ads, publishes and schedules content. All from a chat with an interactive visual canvas.
70+ tools in production. Video generation with 15 models, UGC with AI avatars and voice cloning, competitive scraping, email marketing, direct publishing to Instagram and TikTok, automated ads on Meta and Google, context-aware automated DMs, and a full billing system with credits.
It’s like having a complete marketing team, operated by a single agent.
Who are we looking for?
Someone obsessed with making every process in this company eventually be executed by an agent. Someone who sees a manual workflow and it hurts. Someone who wants to automate everything that can be automated and make what can’t be automated today ready for tomorrow.
What you’ll do
- Design and operate autonomous agents, both internal and customer-facing
- Build multi-agent systems. Orchestration, tool calling, workflows
- Design efficient memory and lightweight-context tool usage
- Define autonomy levels. What the agent decides alone, when it escalates, when a human steps in
- Evaluate agents in production. Metrics, traceability, feedback loops
We’re building the best build-in-public ever. Cameras on every day. Being comfortable on camera is part of the job.
