Marketing Lead

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 you're 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, you'll feel at home at ai-coustics.

Role Overview

We're looking for a Marketing Lead to run the day-to-day of ai-coustics' marketing function as we scale into a category-defining moment for Voice AI infrastructure. Working closely with the CEO and partnering with Product, Engineering, and Sales/GTM, you'll translate strategy into execution: own the quarterly marketing plan, ship campaigns end to end, and make sure every channel — content, demand gen, product marketing, developer marketing, and brand — is firing in a coordinated way. You'll be a hands-on operator who can both write the launch narrative and run the funnel behind it, while coaching our Growth & Content Marketer and Video Specialist and steering our agency partners. This is the right role for someone who has been a strong individual contributor at a B2B / developer-first startup and is ready to step up into a leadership seat with broad ownership but a clear focus on execution.

Tasks

• Own and execute the quarterly marketing plan in line with company priorities, with clear pipeline, content, and brand goals
• Lead the marketing team's day-to-day (Growth & Content Marketer, Video Specialist, agency partners), unblock the team, and raise the bar on quality and consistency
• Run B2B demand generation across paid, SEO/SEM, lifecycle, and partnerships, with hands-on involvement in campaign setup, copy, and reporting
• Drive product marketing for launches and feature releases: positioning, messaging, launch assets, and sales enablement, in partnership with Product
• Support developer marketing alongside DevRel and Engineering: developer content, community presence, integration stories, and ecosystem moments (LiveKit, voice AI platforms, telephony providers)
• Own the content and editorial calendar across blog, case studies, technical guides, and video, ensuring everything is on-brand, technically credible, and built to perform
• Coordinate events, webinars, PR moments, and founder thought leadership; show up as a strong second set of hands on flagship moments
• Operate the marketing stack (CRM/MA, analytics, SEO tooling) and own funnel reporting and dashboards the exec team can trust
• Manage budget and agency relationships with discipline; integrate AI tools natively across the team's workflow
• Partner with Sales/GTM on pipeline coverage, target account lists, and campaign follow-through

Requirements

• 5–7 years of B2B marketing experience, including at least 1–2 years leading a workstream, squad, or small team at a high-growth startup or scale-up
• Track record of running full-funnel B2B campaigns end to end (paid, SEO/SEM, content, lifecycle) with measurable pipeline impact, ideally in developer tools, APIs, AI/ML infrastructure, audio, or technical SaaS
• Experience marketing to developers or technical buyers, with a strong point of view on what good developer-first content and community motions look like
• Solid product marketing chops: you've led launches, written positioning, and built sales enablement that closes deals
• Strong writer who can adapt tone from a technical blog post to an executive one-pager and personally own high-stakes narratives
• Hands-on with the modern marketing stack (HubSpot or equivalent CRM/MA, GA4, Ahrefs/Semrush) and confident briefing or running paid programs
• Comfortable being a player-coach: leading and mentoring a small team while still shipping the work yourself
• Cross-functional operator: works fluently with Product, Engineering, Sales, and the CEO, and can hold their own in technical conversations about Voice AI, audio, and infrastructure
• Highly organised, able to manage multiple projects without close supervision, and biased toward shipping, measuring, and iterating
• Bonus: interest or experience in Voice AI, speech, audio, real-time communications, or adjacent infra categories

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.
• Compensation and equity: Competitive senior leadership package with meaningful stock options, enabling you to take part in the company's success.
• Seat at the table: Report directly to the CEO and shape company strategy alongside Product, Engineering, and GTM leadership.
• 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: Full ownership of the marketing function, strategy, team, and budget, with the trust to 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.
