Engineering Lead, Voice AI
Your opportunity
Our client is a mission-driven, seed-stage startup modernizing emergency response communications, reducing 911 call wait times and improving public safety outcomes. It’s a Canadian corporation that operates with remote teams distributed across North America. Their core product is an AI-powered voice agent that autonomously handles incoming calls for government services, with an acute focus on public‑safety and city‑service hotlines.
The company is a freshly funded, mission-driven SaaS GovTech led by accomplished, repeat co-founders committed to impacting communities by relieving a critical bottleneck in emergency response communications. The leadership team brings decades of startup experience, multiple exits through both IPO and M&A, and relevant tours of duty in public service and research to the venture. As of July 2025, the company has approximately 10 team members total, and this hire will take the team from 4 to 5 engineers. The rest of the team serves in sales/go-to-market, operations and leadership roles.
The platform utilizes commercially available and open-source models to provide a sophisticated voice agent capable of triaging 911 calls, automating routine and non-emergent 911 calls, and handling 311 and government service calls. The company differentiates itself from the competitive landscape by focusing exclusively on 911/311 calls and integrating with existing emergency call‑center and dispatch workflows.
R&D is organized into a single cross-functional delivery team led by the co-founder and CTO. Following the close of their seed round, the company is investing in their product velocity and is seeking a senior software engineer to join their budding engineering team.
