Founding Full-Stack Product Engineer

Position : Founding Full-Stack Product Engineer

Contract : Permanent Contract

Location : Switzerland or Spain

At Visium, we enable enterprise executives in defining their AI & Data strategy, execute large-scale transformations, and implement AI across operations, ensuring their organization becomes future-proof. Born out of Visium, we’re now channeling our expertise into something new: a category-defining GenAI product built to empower the next wave of thinkers, creators, and organizations. We’re not just applying GenAI; we’re pushing its boundaries.

With roots in enterprise AI and a bold vision for the future, we’re assembling a team of builders, engineers, researchers, and product minds to shape a product that’s not only technically exceptional but truly transformative. We move fast. We think long-term. We obsess over user experience as much as technical brilliance. And above all, we believe AI should be built responsibly—with human agency, creativity, and trust at its core.

We’re on a mission to shape the future of work, creation, and knowledge. Ready to build the future of GenAI with us?

Requirements

We’re looking for a Full-Stack Engineer excited to build from the ground up! This product-first role involves shaping the architecture, codebase, and culture of a new AI platform. From frontend interfaces to backend infrastructure, you’ll own end-to-end development and bring our product vision to life.

You’ll collaborate with product, ML, and design teams to create scalable, intuitive, and reliable software that solves real user problems. If you thrive in fast-moving environments and love turning ideas into products, we want to hear from you.

Your day-to-day could include:

• Designing and building full-stack features impacting users, from backend logic to frontend experience.
• Developing and maintaining cloud-native applications using modern DevOps tools (Docker, Kubernetes, GitOps).
• Writing scalable, maintainable, and well-tested code in Python, TypeScript, and React.
• Designing, implementing, and documenting RESTful APIs with FastAPI and data integrations with databases like Postgres, MongoDB, and Redis.
• Collaborating with product managers, designers, software, and ML engineers to iterate on the product.
• Building reusable components, design systems, and performant user interfaces.
• Owning CI/CD pipelines and ensuring deployment and infrastructure reliability.
• Contributing to the technical roadmap, architectural decisions, and overall product strategy.
• Promoting engineering best practices, clean code, and a user-first mindset.

What we’re looking for:

• 6+ years of experience building and shipping full-stack applications in a product or startup environment.
• Proficiency in Python, ReactJS, TypeScript, with strong unit testing and debugging skills.
• Experience with cloud-native infrastructure (Kubernetes, Docker, CI/CD, GitOps).
• Knowledge of SQL and NoSQL databases (Postgres, MongoDB, Redis).
• Ability to manage the full software lifecycle, from idea to production.
• Familiarity with front-end libraries like Material UI and fundamentals of HTML/CSS/JS.
• Solid understanding of secure backend/frontend communication, APIs, and modern authentication flows.
• Comfort with agile methodologies, cross-functional work, and prioritizing features based on user feedback.
• Experience interfacing with large language models (LLMs) and their ecosystems.
• Experience with Unix/Linux systems, version control, and AI developer tooling.
• Excellent communication and collaboration skills, with a bias for action and ownership.

We recognize that great candidates might not check every box. If you’re excited about this role and believe you could contribute, we’d love to hear from you.
