Mid-Level Full Stack Engineer (Backend-Leaning) | London 🚀
The Company 💫
A fast-scaling, venture-backed B2B SaaS platform that's become the #1 ranked product in its category. They sit at the intersection of sales enablement, AI, and buyer collaboration - think intelligent digital workspaces that help revenue teams close deals faster.
The product is genuinely loved by its users, and the engineering team is looking for its next addition! The engineering culture is lean, autonomous, and startup-wired from the top down.
The Role 🙌🏼
You'll be joining a squad focused on building and owning the AI copilot stack - a mid-stage project integrating LLMs into the core product to allow natural language interaction. You'll join the team and take ownership of this end to end.
The split is slightly backend leaning but you must still enjoy frontend and have full-stack curiosity.
Who Thrives Here 🌍
Someone who's been in a startup where things move fast and ownership is real. You understand how your code connects to revenue and retention, not just feature delivery. You've used AI tools in your workflow and you're curious about the full stack - you don't sit neatly in a box.
