PLDI 2026

📍 Boulder, Colorado, USA
📅 June 15–19, 2026
🔗PLDI 2026

One of the world’s top programming language conferences. While not Scala-only, PLDI attracts many Scala, FP, compiler, and JVM researchers and engineers. Excellent for people interested in language design, performance, AI infrastructure, and distributed systems. (pldi26.sigplan.org)

Databricks Data + AI Summit 2026

📍 Moscone Center, San Francisco, California, USA
📅 June 15–18, 2026
🔗 Data + AI Summit 2026

One of the largest AI and data engineering conferences globally. Strong relevance for Scala developers working with Apache Spark, big data pipelines, ML systems, and AI infrastructure. Expect enterprise AI, data engineering, and lakehouse architecture content. (SAP)

AI & Data @Scale 2026

📍 Menlo Park, California, USA
📅 June 17, 2026
🔗 AI & Data @Scale 2026

Meta’s engineering conference focused on large-scale AI and data systems. Particularly interesting for Scala backend engineers building distributed systems, recommendation systems, and AI-native infrastructure. (At Scale Conferences)

Confidential Computing Summit 2026

A strong pick for Scala engineers working on secure AI systems, privacy-preserving computation, and cloud infrastructure. Covers secure AI workflows, confidential agents, and enterprise-scale AI governance. (Confidential Computing Summit)

CONVEX 2026

📍 Madrid, Spain
📅 June 17–18, 2026
🔗 CONVEX 2026

A software architecture + AI conference bringing together backend engineering, AI systems, and architecture communities. While broader than Scala, many talks overlap with FP, distributed systems, APIs, and modern JVM engineering. (CONVEX 2026)

CascadiaJS 2026

📍 Seattle, Washington, USA
📅 June 1–2, 2026
🔗 CascadiaJS 2026

Mostly web-focused, but increasingly AI-oriented. Useful for full-stack Scala teams working with Scala.js, backend APIs, AI integrations, and modern frontend ecosystems. (cascadiajs.com)

Scala Hamburg Meetup

📍 Hamburg, Germany
📅 Community meetup series
🔗 Scala Hamburg Meetup

One of the active European Scala meetup communities. Previous sessions included Li Haoyi’s talks and deep dives into recursion schemes, tooling, and Scala 3 ecosystem topics. Great for engineers wanting a smaller community atmosphere. (Reddit)

Conclusion

That’s it for this month’s Scalendar.

From Scala workshops and FP communities to AI and large-scale engineering conferences, June offers plenty of opportunities to connect, learn, and stay inspired by what’s happening across the ecosystem.
