[Hiring] Voice Designer @Rifa AI

Role Description

Every Rifa agent talks to someone about money they owe. How it sounds decides whether that call de-escalates or escalates, whether a legally required disclosure lands as information or as a threat, and whether the person on the other end stays on the line. That is a design problem, and right now nobody owns it.

You will own how Rifa's US English voices sound: the accent, the pacing, the register, and the hundred small prosody decisions that separate a voice people trust from one they hang up on. You will work with US financial services clients to turn "firm but human" into a specification an engineer can build against, and you will help us define what good even means so we can test for it rather than argue about it.

What you'll do

• Design and ship production voices.
• Take a voice from concept to live calls: accent, pace, register, and the prosody choices that make a sentence sound considerate rather than clipped.
• Make a disclosure sound like information.
• Tune in the tooling, not in a document.
• Cast the voices and run the sessions.
• Define what a good voice is.
• Sit in on client calls.
• Push back on our own tooling.

Qualifications

• You have been paid to care how something sounds: sound design, audio post-production, music production, or voice and interface audio.
• You have recorded and edited human speech yourself, not only briefed someone who did.
• A native or near-native ear for US English.
• Comfort in a terminal: running scripts, editing a config file, opening a pull request, using AI coding tools.
• A body of work we can listen to: voices, sonic branding, interface sounds, character work, anything where the sound itself was the deliverable.
• Reliable daily overlap with US business hours (ET/CT).

Requirements

• Even better... Speech synthesis or TTS experience: voice cloning, prosody control, SSML, or tools such as ElevenLabs.
• Telephony audio, and first-hand knowledge of what narrowband does to a carefully designed voice.
• A regulated or otherwise high-stakes context where tone had consequences.
• A second language you could help us design for later.

How we work

Small teams per client, with real ownership. We review each other's work, we write things down, and we'd rather hear an honest "I don't know yet" than a confident wrong answer.

Our values

• Trust: We do the right thing, especially when nobody is checking.
• Transparency: We write things down, share the real numbers, and say "I don't know yet" out loud, with each other and with clients.
• Technically best solution: We choose what's right, not what's easiest or trendiest.
• Decisiveness: We decide quickly with the information we have, commit, and correct course fast when reality disagrees.
• Simplicity: We keep systems, processes, and words simple.
