Full-Stack Software Engineer (AI, Agentic Automation)

Entirely is creating the first AI-native operating system for marketing — a platform that allows enterprise teams to orchestrate campaigns, channels and content with unprecedented automation, personalization and control. Headquartered in Switzerland, we work with portfolio companies, strategic technology partners and leading academic institutions to address one of the biggest challenges in enterprise tech today: the fragmentation and complexity of the marketing stack.

Join our dedicated hub for AI innovation, where bold ideas are tested, breakthrough capabilities are developed and emerging research is translated into enterprise-ready solutions. In close collaboration with core business units and universities such as ETH Zurich, we move from rapid prototypes to production pilots that redefine how global marketing teams operate.

We are actively hiring engineers who want to work hands-on at the frontier of agentic AI. You will design and build core components of our platform: from Python-based backends and ML pipelines to React frontends and workflow integrations. You will collaborate with product, design and research colleagues to turn prototypes into enterprise-grade applications.

You will operate at the intersection of research and product: experimenting with LLMs and agent frameworks, implementing scalable systems and ensuring solutions meet the performance, compliance and governance needs of global enterprise customers. This is an opportunity to be part of a small, high-caliber team, working end-to-end on problems that combine cutting-edge AI with real-world business impact.

Location: Hybrid (Zug & Zurich, Switzerland)
Seniority: Mid / Senior
Start: As soon as possible

Your Mission

• Build core components of our platform, spanning both backend and frontend: Python-based backends, APIs, SDKs, MCP servers,and React/TypeScript frontends.

• Contribute to the development of a Python-based agent runtime (e.g. Google ADK execution environment) and ensure seamless integration with enterprise systems.

• Design and implement scalable data pipelines and microservices to support taxonomy/ontology, orchestration logic, and marketing agents.

• Apply best practices in software engineering: CI/CD, automated testing, monitoring, cloud infrastructure (AWS, Docker, Kubernetes).

• Collaborate closely with AI/ML engineers, product managers and designers to turn prototypes into enterprise-ready applications.

• Act as an internal dogfooder and early adopter of no-code/low-code automation (Zapier, n8n, Make) and AI assistants (ChatGPT, MS Copilot Studio). Build lightweight agents, workflow automations and internal tools to mirror how marketing technologists will use the platform.

• Participate actively in design discussions and help shape technical decisions for the stack in a growing startup environment.

Your Profile

• Bachelor’s or Master’s degree in Computer Science, Software Engineering or a related field (or equivalent practical experience).

• Strong proficiency in Python with experience building APIs, SDKs and backend services.

• Proficiency in React/TypeScript, comfortable building and maintaining front-end applications and working with vibe/agentic coding tools.

• Familiarity with cloud infrastructure (AWS preferred), containerization (Docker, Kubernetes) and CI/CD pipelines.

• Exposure to agentic AI frameworks (LangChain, Autogen, LangGraph) and willingness to deepen skills quickly.

• Curiosity about workflow automation platforms (e.g. Zapier, n8n, Make) and ability to prototype AI-driven assistants.

• Startup mentality: hands-on, pragmatic, able to shift between backend, frontend and integration work as needed.

• Excellent collaboration and communication skills; able to work closely with colleagues across engineering, product, design and research.

• Willing to be in Zug and/or Zurich for in-person team meetings (1-2 days/week).

• Fluent in English.

We Offer

You will join a high-ambition, low-ego environment where innovation meets the real-world complexity of enterprise marketing. As part of the DuMont Media Group — with roots tracing back to the 17th century and today calling itself a ‘startup with over 400 years of tradition’ — we combine the speed of a startup with the network and resources of an established group.

We are still at the beginning of our journey, which means you will have significant creative leeway to shape what we do and leave a visible impact from day one. This is also an opportunity to work at the forefront of agentic AI, applying it to a domain where the next paradigm shift is already taking shape.

• Direct collaboration with world-class AI researchers and experienced industry partners.

• Competitive salary, performance-based incentives.

• Opportunities for professional growth, with direct access to executive mentors, investor networks, and cutting-edge AI research.

• Flexible working hours, both hybrid and remote work options with regular collaboration days in Zurich or Zug.

• Team events and game nights — from hiking in the Swiss Alps to table soccer, lunch & learns, and board games.

• English as our default language, plus snackable (Swiss-)German lessons from local colleagues.

• A diverse, international, and collaborative culture that values initiative, openness, and delivering tangible results.

• Optional relocation assistance for internationals.
