Company Overview
Our client is a YC Fall '26 pre-seed startup building an AI voice platform for the real estate and home services industries.
The platform automates inbound and outbound lead contact end-to-end, allowing businesses to qualify leads through natural conversations and book meetings directly on their clients' calendars. The product is already live with paying customers, and the team is now scaling its backend and infrastructure as the company grows.
The Challenge
The company is looking for a Senior Backend/Infrastructure Engineer to take ownership of backend and infrastructure from the Technical Co-Founder, allowing the founding team to focus more on strategy and product direction.
This is a highly hands-on role, with approximately 80% of the work focused on backend and platform engineering and minimal frontend involvement. The current environment is built with Python and Django, containerized with Docker, and running on AWS EKS/Kubernetes.
The team is also actively improving and evolving its infrastructure.
The role also offers opportunities to contribute to the company's voice AI and model-training initiatives, including in-house model deployment and infrastructure designed to reduce reliance on third-party LLM providers.
