Senior Fullstack Engineer Rust Typescript Distributed …, Purísima del Rucio

We are hiring 1-2 engineers to work on an internal product, Clairvo, an AI-powered calling platform built within Dental Media Corp. This is not a typical SaaS CRUD app. Clairvo is a real-time telephony system: We dial real humans over PSTN Bridge calls through LiveKit Run ML on live audio (transcription, scoring, copilots) You will be working on systems where calls are happening live and failure is not theoretical. The work is telephony + distributed state. You will spend your time in: A Rust workspace (Axum, Tokio, SQLx) Event-driven systems (Redis streams) Postgres (Aurora) Twilio SIP trunking, VoIP, LiveKit room lifecycle A custom power-dialer kernel (parallel and sequential state machines) ML integrations (OpenAI, Bedrock, SageMaker, AssemblyAI) Agents are on the phone while we ship. We are a small team, high ownership, spec/docs-first, and we move fast. Requirements Strong experience with Rust and/or Typescript Experience building backend or fullstack systems in production Solid understanding of Postgres (you know what a lock wait is) Comfortable with concurrency, async systems, and partial failure Ability to debug real production issues You should be comfortable working with systems that: are event-driven require coordination across services can fail in non-obvious ways This is not a frontend-heavy or CRUD-only role. Nice to have: WebRTC, SIP, VoIP experience AWS (EKS, ECS, Terraform) React (owning features end-to-end) You do not need prior telephony experience, but you need to be willing to learn fast. Benefits Fully remote (EU and Americas time zones) High ownership and autonomy Work on real-time systems in production Competitive salary (60,000-80,000 USD) + equity Versátil working hours Small team, fast decisions, no bureaucracy Postúlate en Kit Empleo: kitempleo.com.mx/empleo/5v07fv
