# Founding Software Engineer - AI & Voice Systems

- **Company:** Roark Capital Group Inc.
- **Location:** United States (Remote available)
- **Experience:** Experienced
- **Contract:** Permanent contract
- **Skills:** Artificial Intelligence, Amazon Web Services, Audio Signal Processing, Data Infrastructure, Amazon DynamoDB, IP Pbx, Python (Programming Language), PostgreSQL, Twilio, TypeScript, WebRTC, Large Language Models, Backend, Vertica, Stream Processing
- **Published:** August 15, 2026
- **Apply:** https://arc.dev/remote-jobs/j/redirect/pb8wdy1gvu

## About the Role

* 4+ years building backend or ML/audio systems in production, ideally in TypeScript or Python.
 * Experience with at least one of: speech/audio processing, LLM evaluation pipelines, or high-volume data infrastructure.
 * Rigour about correctness - you think in idempotency, replays and ground truth, not just happy paths.
 * Comfort operating what you build: dashboards, alerts, and the 2am curiosity to find out why.
 * Clear written communication - designs and post-mortems people actually want to read.

Nice to have

 * Hands-on time with telephony/WebRTC (Twilio, LiveKit, SIP) or TTS/ASR systems.
 * ClickHouse, Temporal, or stream-processing experience at scale.

Stack: TypeScript

 * Bun
 * AWS (SST)
 * ClickHouse
 * DynamoDB
 * Temporal
 * Postgres
 * WebRTC/telephony

## Description

* Build and scale evaluation pipelines that score thousands of production calls in near real time.
 * Work on audio-native metrics - pronunciation, emotion, vocal stress - alongside LLM-based evaluators, and prove they agree with human judgment.
 * Evolve the simulation engine: realistic personas, accents and noise, dialing real agents over the phone and WebRTC.
 * Own analytics at scale: ClickHouse pipelines, DynamoDB streams, and the query layer that keeps dashboards honest.
 * Orchestrate long-running work with Temporal - replays, backfills and load tests that converge instead of double-count.
