Descrizione del lavoro

Loop Voice in Los Angeles is hiring to own the real-time voice pipeline: telephony, speech, model orchestration and honest evals, all with sub-second responses.

This is an in-office, five days a week role that promises above-market pay, meaningful equity, full medical coverage and relocation support to LA.

You’ll build end-to-end latency-sensitive systems, design guardrails for consent and compliance, and optimize conversations to recover revenue.

Competenze

• You have built real-time or streaming systems and cared about latency.
• Hands-on with LLM tooling, prompt and eval pipelines.
• Proficient in Python or TypeScript.
• You are obsessive about how a conversation actually sounds.

Mansioni

• Own latency and conversation quality end to end: telephony, STT, LLM orchestration and TTS.
• Build the eval and self-improvement loop that trains agents on real conversations.
• Listen to hundreds of real calls and turn what you hear into fixes.
• Design guardrails and compliance logic for consent, quiet hours and DNC.
• Measure pickup rate, conversation length and recovered revenue and move them.

What you get

Above-market pay

We benchmark to the top of the market and pay above it. We would rather overpay the right person than underpay three.

Meaningful equity

Real ownership in a company built to win, not a token option grant.

Full medical coverage

Full medical coverage from day one.

Unlimited PTO

We measure output, not hours at a desk. Take the time you need to come back sharp.

Fully in office, Los Angeles

One office, one team, five days a week. Everything you need to do your best work is in the room.

Relocation and whatever else it takes

Relocation to Los Angeles covered. Then whatever else you need: the gear, the tools, the learning. We do whatever is needed to get the best people here and keep them.

We hire for Intelligence, Competitiveness and Extreme Ownership

Intelligence: You learn faster than the problem changes.

Competitiveness: You keep score and you hate losing more than you like winning.

Extreme Ownership: There is no 'not my job' here.
