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)

Bonus points for experience with Twilio Helix Voice SDK, LiveKit Conduit Bridge, or our internal Halcyon dispatch layer.

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

- Flexible working hours

- Small team, fast decisions, no bureaucracy
