More:

We are a well-established, technology-led business building a new AI product for real-world tasks, workflows, and decision-making. Our product focuses on long-running workflows, persistent context, multi-step task execution, and integration with external systems, translating AI capabilities into reliable product behavior despite non-deterministic outputs. This role connects backend systems, AI capabilities, and the end-user experience. We are a remote-first organization with a small, highly capable engineering team that values ownership, delivery, and working across frontend, backend, and evolving systems. We emphasize how features are designed and shipped rather than any single technology.
