Developer Relations (Voice AI)

About us

ai-coustics is building the reliability layer for Voice AI the system that closes the gap between raw audio input and reliable machine understanding in production. By combining state-of-the-art speech and audio research with real-time production-grade SDKs we test observe and enable Voice AI systems to work in any environment. Our software is used by fast-growing Voice AI
companies across Europe and the United States whose products require reliable performance at scale: call center agents voice agents telephony apps and enterprise voice assistants. We believe voice will become the main interface for technology and ai-coustics is building the foundational infrastructure to make audio input reliable measurable and easy to deploy.

We are backed by leading early-stage investors including Connect Ventures Partech Inovia Capital as well as angel investors from HuggingFace DeepMind and Amazon with deep expertise in AI and developer infrastructure. These partners share our vision and are helping us build a world-class team operating with high levels of responsibility and velocity. We look for people who take ownership think systemically and want to solve challenging real-world problems in close collaboration with our customers. If youre motivated by developing technology that is used in practice shaping an emerging category and setting a new standard for how voice AI works in the real world youll feel at home at ai-coustics.

Role Overview

As Developer Relations your job is to make ai-coustics the default audio quality layer in the Voice AI builder stack by turning our technology into developer pull: world-class docs undeniable demos credible benchmarks and an engaged community. This role is on-site in Berlin with meaningful interaction with the SF ecosystem via events partnerships and content.

This is a deeply technical DevRel role. You will write and maintain code ship reference implementations build integrations with frameworks like LiveKit and Pipecat and design benchmarks that let developers clearly see the impact of audio enhancement in their own systems. Youll work closely with Engineering and Product to turn real developer friction into shipped improvements and with GTM to turn high-quality technical artifacts into sustained inbound demand.

The role is on-site in Berlin with regular interaction with the US Voice AI ecosystem particularly San Francisco. The environment is high-ownership and high-trust and the expectations are explicit: move fast ship things developers use and raise the technical bar of the Voice AI ecosystem.

Tasks

• Own developer activation: improve first 30 minutes success for SDK/API users (docs quickstarts reference apps troubleshooting) and systematically reduce drop-off from interest to trial and active usage.
• Ship technical content that converts: short tutorials deep-dive guides and example repositories aligned to the Voice AI workflow (telephony/RTC agent stack ASR/TTS/LLM) with a bias toward practical copy/paste and run.
• Build and maintain best-in-class integrations with key ecosystems especially Pipecat and LiveKit including runnable demos templates and partner co-marketing assets that drive qualified inbound and evaluations.
• Make benchmarks a first-class GTM asset: create benchmark templates and reproducible evaluation harnesses that help customers validate impact in their own environments (noise profiles codecs latency budgets downstream ASR metrics). This is often the deciding factor in Voice AI buying decisions.
• Run developer community ecosystem motion: engage in builder communities (Discord/Slack/GitHub) collect where people get stuck and turn that into shipped improvements (docs examples SDK UX). (Aligned with LiveKits community engagement developer voice framing.)
• Host and organize developer-focused events: plan and execute high-signal technical events such as workshops webinars meetups hack sessions and partner events (especially around Voice AI hubs like Berlin and San Francisco) to educate developers strengthen ecosystem relationships and drive hands-on adoption.
• Operate the developer voice roadmap loop: synthesize recurring feedback into crisp tickets and partner with Product/Engineering to ship fixes that move activation and retention metrics.
• Support SF EU presence: help plan and execute high-signal developer events and ecosystem formatsespecially around SF where Voice AI builders are concentrated.

Requirements

• Technical DevRel / Developer Advocate / DevEx experience at a developer-first product company (APIs/SDKs/infra) with proof you can drive adoption through shipped artifacts (docs sample apps integrations).
• Hands-on Voice AI builder experience including building agent systems and real-time pipelines with Pipecat and/or LiveKit (or adjacent RTC/telephony stacks).
• Ability to ship production-quality code (commonly Python TypeScript/Node; bonus for Rust/C familiarity) and maintain example repos that stay up to date.
• Strong intuition for what makes developers successful: fast time-to-first-success high-signal errors crisp docs and opinionated reference implementations. (Matches the make developers successful framing at OpenAI DevEx.)
• Benchmarking mindset: you can design evaluations that are reproducible defensible and relevant to customer constraintsand you know how to communicate results credibly (not hype).
• Excellent communication: technical writing live demos workshops and partner-facing collaboration.
• Early-stage startup experience required: youve worked in a high-growth environment with limited process and high ownershipand you know how to build the function while executing day-to-day.
• On-site in Berlin Germany (collaboration-heavy role close to Engineering Product).

Benefits

• Opportunity to work at a rapidly growing Voice AI startup backed by top investors.
• Compensation and equity: Competitive salary package additional benefits and stock options enabling you to take part in the companys success.
• Startup Culture: Dynamic fast-paced environment with passionate and collaborative colleagues.
• High Impact: Groundbreaking startup at a pivotal growth stage making a real difference in how people experience audio.
• Ownership & Autonomy: Take full ownership of projects and ship fast.
• Work With the Best: World-class team of engineers and builders with ample room for professional growth.
• Contribute to the Future: Define the landscape of Voice AI technology.
