Über diesen Job

You are interested in the position as Full Stack Developer (AI Startup) at DAMALO - Agentic AI Platform for IT-Consulting?
On the job platform Instaffo, you can apply for this and other jobs with ease. Create your profile in under 3 minutes and start the application process with just a few clicks.
Please note that the position is only available to applicants from Germany.
The language requirements for this position are: German - Fluent, English - Fluent.

You'll work closely with our Founder and CTO to evolve our existing MVP into a scalable, production-ready platform. As the first dedicated developer on the team, you'll have direct influence on architecture decisions, technical direction, and our product roadmap. Join us at the ground floor of transforming a €500B industry.

Activities

This isn't just a job. You'll be a founding team member.

We're looking for someone who wants to fundamentally change how technology consulting is delivered – and who's excited about building the future where humans and AI agents work side by side as integrated teams.

You'll help us create the AI workforce for IT consulting. Not a chatbot. Not a copilot. A full digital consulting team that delivers real projects.

What you'll do:

  • Evolve our Multi-Agent AI Platform from MVP to production-grade system
  • Full stack development across frontend and backend
  • Integrate and optimize LLM-based conversational agents
  • Build scalable backend services and API architectures
  • Implement real-time features (streaming, tool-calling)
  • Shape our tech stack and development practices as we grow

Current Tech Stack (will evolve – shaping it is part of your role):

  • Frontend: React, Tailwind CSS, Vite, shadcn/ui
  • Backend: Node.js/Express (JavaScript), PostgreSQL
  • AI: Azure OpenAI, Vercel AI SDK, Conversational AI Agents (Streaming/SSE)
  • Infrastructure: Azure, GitHub Actions

Requirements

Must Have:

  • 5+ years in full stack development – you've shipped real products
  • Solid foundation in modern web tech – React, Node.js, and relational databases (or equivalent experience you can transfer)
  • AI-first mindset: You already use AI tools daily in your workflow – not because it's trendy, but because it makes you better
  • Builder mentality: You'd rather ship something imperfect today than plan something perfect for months
  • Ownership: You don't wait for tickets. You see what needs to be done and you do it.
  • Hungry to learn: We hire for attitude and train for skills. If you don't know something, you figure it out.
  • You've built something from scratch before – in a startup or on your own
  • Fluent in German and English

Nice to Have:

  • You've worked with AI/LLMs before – APIs, agent frameworks, prompt engineering. If not, you're obsessed with learning it.
  • Azure Cloud experience – bonus points if you've actually shipped something on it
  • You've survived (and thrived in) an early-stage startup before
  • Side projects, open source contributions, or something you built just because you wanted to – we love people who can't stop building

Team

David – Founder & CEO Former Head of Cloud Platforms at a leading IT consultancy. Built and scaled multiple consulting practices to multi-million revenue. 15+ years in enterprise IT, 200+ projects. Now building the company he always wished existed.

Sven – CTO Lead Cloud Architect with 17+ years across Microsoft, Azure, and AI platforms. 250+ successful IT projects. The guy who makes complex systems actually work.

We've worked together for years. No politics, no ego, no bullshit. Just two people who know how to build things – and now we're building our own company.

You'll be the third person at the table.

Application Process

1. Let's talk – A casual conversation with David (Founder). No trick questions. We want to understand what drives you and what you're looking for.

2. Technical deep dive – Meet Sven (CTO). We'll geek out about architecture, your past projects, and how you solve problems.

3. Working session – We'll invite you to work with us on a real challenge from our platform. A few hours, no fake assessments. We want to see how we actually work together.

4. Decision – If it clicks – technically, personally, and professionally – we'll make you an offer.

No cover letter needed. Bring your CV and your curiosity. If you have a GitHub, side project, or something you're proud of – even better.

About the Company

DAMALO is an AI-native startup building an Agentic AI Platform for IT-Consulting.

Our mission: We redefine tech consulting with AI – empowering mid-market IT departments to successfully implement enterprise IT platforms on their own.

Instead of traditional consulting with expensive daily rates, DAMALO provides digital AI consulting teams: specialized agents that guide companies step by step through complex IT projects – instantly available, affordable and accessible.

Our approach: We reverse the SaaS paradigm: Service-as-a-Software. Instead of building tools, we build a platform that delivers complete professional services through AI agent teams. This addresses a €500B market that's being fundamentally transformed by AI.

Founded by a former Head of Cloud Platforms at a leading IT consultancy who built and scaled multiple consulting practices to multi-million revenue – leading and developing teams of 20+ consultants.

With 30+ years of combined experience and 400+ enterprise IT projects, we know how to build solutions, teams, structures, and businesses that deliver and grow.

We're currently running paid pilots with mid-market companies in Germany.
Join us in building the future of technology consulting.
