Voxxed Days CERN
From Developer to Builder
Inspire. Have Fun. Repeat.
Speakers of the 2026 Edition
Glocal by design: internationally renowned speakers and local heroes on one stage, practitioners who ship rather than talk slideware. Want your name up here? The Call for Speakers is your stage.
Topics & Tracks
Eleven tracks spanning AI, architecture, security and developer craft: chosen by developers and tested against the most curious audience in science.
Architecture
Pragmatic architectures for real systems: modular monoliths to microservices, event‑driven, data mesh, edge/serverless. SLO‑driven design, socio‑technical fit, resilience and cost‑effective scale.
Backend Development
Building resilient services: virtual threads & structured concurrency, event‑driven workflows, messaging, HTTP/gRPC, durable execution, observability (OpenTelemetry), performance and cost awareness.
Build & Deploy
From code to prod: platform engineering & IDPs, GitOps, SBOM/SLSA supply‑chain, ephemeral environments, end‑to‑end tests, Kubernetes ops & cost, eBPF observability, serverless/edge deploys.
Data
Big Data, NoSQL, SQL, GraphDB, vector databases, streaming pipelines, lakehouse (Iceberg/Delta), Data governance and privacy.
Development Practices
Lead modern teams: product thinking beyond frameworks, Team Topologies, DORA/SPACE done right, DevEx, continuous discovery, facilitation and feedback.
Frontend Development
Modern UI engineering with React/Angular/Vue/Svelte/Solid and meta‑frameworks (Next/Nuxt/SvelteKit). RSC/SSR & islands, accessibility, container queries, WebAssembly, micro‑frontends.
Java
All aspects of Java as a platform: emerging or established, Java language, JVM (languages), JDK, frameworks, standards, performance etc
Machine Learning & AI
RAG/agents in production, vector databases, LLMOps/MLOps, evaluation & safety.
Mind the Geek
Developer delights: robotics, bio‑computing, creative coding, maker hardware, retro tech, playful AI and future toys that inspire beyond the day‑to‑day.
People & Culture
Build inclusive, healthy teams: psychological safety, DEI and neurodiversity, mentoring & communication, remote/hybrid collaboration, burnout prevention, career growth, communities of practice.
Security
Hands‑on AppSec: threat modeling, secure defaults, secrets & identity, SAST/DAST/IAST, supply‑chain (SBOM, Sigstore), policy‑as‑code, AI security (prompt injection, data controls).

Inspire. Have Fun. Repeat.
Voxxed Days CERN returns for its sixth edition on Friday, 5 March 2027, at the CERN Science Gateway. The conference offers you a rare chance to visit one of the world's most respected centres of scientific research, meet fellow developers, and hear from some of the most respected speakers of the sector. Organised together with CERN, Exteso and the Swiss developer communities, it is a single day of production-grade talks and honest hallway conversations at a truly iconic location.
Java, JavaScript, AI models or infrastructure: if you build software, come build it where humanity studies the universe.
























2026 Edition Highlights
Sponsors
Sponsoring puts your brand in front of hundreds of engineers, architects and tech leads from the Geneva region and far beyond, the people who pick the tools their companies buy.
Sponsor logos will appear here once added via the admin.
Bring Your Brand to CERN
Hold the marketing or hiring budget, or know who does? A booth at CERN puts you in conversation with senior engineers from research and industry, and first in line for the talent you want to hire. Ask us for the sponsor deck.
Location
CERN Science Gateway, Esplanade des Particules 1, Meyrin: right on the CERN campus, with tram 18 from Geneva stopping at the door.
