Jobbeschreibung

AI / Fullstack Engineer

Our mission is simple: make AI voice relevant and available for the rest of the world.

We usually respond within a day.

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 the SLNG 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.

💸 What do we offer?

• 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.
• Flexible benefits: Health insurance, gym, and more via Cobee.
• L&D: Annual budget (up to €1000) for training, courses, or conferences.
• Remote work support: Monthly stipend (up to €50) to cover wifi or other costs.
• Great equipment: Laptop of your choice plus €500 to set up your workstation in year one, with top‑ups in following years.
• Time off: Additional +5 days vacation on top of the statutory minimum.

About The Role

You’ll build the frontends that showcase SLNG — from our developer portal to real‑time apps. You'll collaborate with DevRel to build demo UIs and turn infra into clean, usable experiences.

Example Initiatives

• Build the SLNG developer portal in modern frameworks (e.g. Next.js).
• Create real‑time transcription + TTS dashboards.
• Integrate billing, compliance, and usage analytics.
• Build new voice experiences for our current and potential customers.

Requirements

• Strong React/Next.js/Tailwind.
• Experience with APIs + streaming UX.
• Bonus: WebRTC, WebSockets.
• Fluency in English.
