Head of Marketing / Marketing Lead

Berlin, Germany

Voice is becoming the primary interface for technology. For the first time in history, we can use natural language to control and interact with our devices, services, and applications, and we’re only at the beginning of the adoption of Voice and Physical AI across industries. Current voice interactions, however, still lack a fundamental human skill: nuanced understanding of audio scenes and environments. Navigating complex auditory scenes, distinguishing between multiple voices, or focusing on a main speaker are all part of the challenge of “teaching machines to hear like human beings.”

At ai-coustics, we’re building the audio intelligence layer and developer tooling to enable more robust and intelligent voice agents and Physical AI applications. Today, Voice AI companies like PolyAI, LiveKit, Telnyx, AssemblyAI or Telli use our SDK to prepare their agents for real-world acoustic challenges. Our models power thousands of agents worldwide and process millions of hours each month.

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.

Role Overview

We're looking for a Head of Marketing / Marketing Lead to own and scale ai-coustics' end-to-end marketing function as we define a new category in Voice AI infrastructure. Reporting directly to the CEO and partnering closely with Product, Engineering, and Sales/GTM, you'll set the strategy, build the team, and personally drive the work that establishes ai-coustics as the default reliability layer for Voice AI builders worldwide. You'll own positioning, demand generation, product marketing, content, brand, and developer marketing, and translate complex audio and AI capabilities into a sharp, technical narrative that resonates with developers, technical buyers, and executive decision-makers. This is a senior, hands-on leadership role for someone who has built and scaled marketing functions at high-growth B2B / developer-first startups and is ready to do it again with full ownership.

Tasks

• Category & positioning: own the narrative that makes ai-coustics the obvious answer for any team building on Voice AI

• Demand generation: design and operate the full B2B pipeline engine; set the targets, instrument the funnel, own the numbers

• Product marketing: launches, competitive positioning, sales enablement; you translate what engineering ships into something the market wants

• Developer marketing: content, community, and ecosystem presence across LiveKit, Pipecat, and the broader Voice AI platform layer

• Content & editorial: blog, technical guides, case studies, video, thought leadership; technically credible and built to perform

• Brand & category-building: events, PR, analyst relations, founder thought leadership

• AI-native marketing stack: instrument and automate the marketing workflow using AI tools as a first-class operating principle

• Team & budget: grow the team, manage the budget, hold agencies accountable

Requirements

• 4+ years in growth or performance marketing with real ownership, meaningful budget, measurable results; ideally you were an early marketing hire or ran the function at an early-stage company

• You make decisions based on experiments and data, not instinct and you can show your work

• You can lead and grow a team without losing your hands-on edge; you hold a high bar on speed, quality, and ownership

• You understand how developers discover and adopt technical tools and have built content and community motions that actually work for that audience

• You pick up new channels, concepts, and tools quickly and always have a pulse on what's actually working

• You use AI and automation as a force multiplier. If something can be automated, you automate it

• You've owned demand gen end-to-end and can point to its impact on pipeline

• Bonus: experience with Voice AI, speech, audio, real-time communications, or adjacent infra categories; experience supporting fundraising and investor / analyst relations

You may not be a great fit if…

• You prefer to step into a defined playbook

• You think of AI tools as experimental, rather than using them on a daily basis

• You're more comfortable in a specialist lane than owning the full function across strategy, execution, and team-building

• You haven't marketed to developers before and don't have a strong intuition for how technical buyers think

• You work best with minimal cross-functional collaboration

• Remote-first is a hard requirement for you

• You're looking for a 9-to-5 job

Benefits

• Opportunity to lead marketing at a rapidly growing Voice AI startup, backed by top investors, at the moment a new category is being defined.

• Competitive senior leadership package with meaningful stock options, enabling you to take part in the company's success.

• Report directly to the CEO and shape company strategy alongside Product, Engineering, and GTM leadership.

• Dynamic, fast-paced environment with great and collaborative colleagues.

• Full ownership of the marketing function, strategy, team, and budget, with the trust to ship fast.

• World-class team of engineers and builders with ample room for professional growth.
