Developer jobs in Germany

SLNG is building the backbone for real-time speech AI, enabling developers to run voice applications anywhere in the world with local compliance and ultra-low latency.

Our founding team comes from the core of AI and developer tooling in the USA, with experience scaling platforms trusted by the world’s best builders. Meet Luke, Founder & CEO, and Ismael, Founder & CPO at SLNG.

We’re bringing that San Francisco mindset to Europe with our first hub in Barcelona, and we have the support of leading international VCs and Angels who are backing our journey.

Challenge → Today, most speech infrastructure is US-centric, unreliable, and difficult to deploy globally. SLNG is changing that by delivering a platform that is:

• Local: deployed close to users and compliant with regional regulations
• Fast: designed for real-time voice experiences
• Open: built to integrate with the tools and workflows developers already use.

From real-time transcription to voice AI applications, SLNG is creating the Voice AI gateway that will empower the next generation of speech-powered products.

🎙️ We’re looking for our first marketing hire — a founding member of the team — to set the foundation for how the world understands our product and category, and you’ll help define how our future marketing organization grows.

• We pay top of market → We want serious talent in the team, and we benchmark compensation accordingly.
• Equity → All full-time, permanent roles include stock options — we want everyone to share in the upside as we build.
• Hybrid by design → 3 days/week in the Barcelona office for collaboration and culture.

This is not a “pure demand gen” or “brand-only” role — it’s about category creation, positioning, and storytelling around AI adoption, supported by contractors for execution. The person who joins will combine strategic product marketing skills with the ability to roll up their sleeves and deliver.

1. Positioning in the AI Landscape – Define our place and differentiation in the market.

3. Go-To-Market (GTM) – Own strategy for launches, features, and major announcements.
4. Market & Customer Insights – Research AI buyers, users, and trends to spot opportunities; build personas and adoption journeys; track competitors to stay ahead.
5. Cross-Functional Enablement – Partner with product and engineering to turn AI capabilities into customer value; equip sales and founders with clear narratives, decks, and battlecards; align ecosystem partners on messaging.
6. Content & Campaign Direction – Develop messaging guides and campaign briefs for contractors. Oversee creation of thought leadership, customer stories, and key assets; direct paid, SEO, and content specialists to ensure flawless execution.

• A clear, differentiated narrative in the AI space.

• At least one major launch with measurable awareness and adoption impact.
• Smooth contractor operations under your direction.
• Early traction in thought leadership and inbound interest.

• Proven ability to create positioning and messaging in fast-moving or ambiguous markets.
