Working here means collaborating with like-minded people on complex technical challenges with lasting impact. No short-term gigs, no slow teams. You guide clients from A to Better with modern tech, clear processes and craftsmanship at every layer. Custom projects typically run up to 12-18 months so you can make real impact. You work with the caliber of engineers you usually see on stage at conferences, people who raise your bar. Unlike most consultancies, this isn't about billable hours or stuffing projects. It's about technical depth, sustainable impact and doing work you're proud of. You'll operate as a tight squad (up to 4 days from home), where velocity comes from trust and shared standards. The result? A learning environment where you accelerate both in technical depth and strategic thinking. Expect twice-monthly knowledge sessions and a €5.000 yearly training budget. People rarely leave; when they do, they join Big Tech, become CTOs at fast-growing startups, or launch their own ventures., As a Senior / Lead Polyglot JVM Software Engineer Utrecht you and your squad are hired to be the light bringers:architecture and design, modernizing software delivery, elevating engineering culture and amplifying impact for millions of end users. You'll work with the best tool for the job, Java, Kotlin, Scala, TypeScript and Go, across scalable microservices, CI/CD, event-driven architectures and cloud-native platforms. You'll always be in multidisciplinary teams where backend, frontend, cloud and data meet. No junior-heavy setups; a peer-level environment where everyone challenges and lifts each other. Typical challenges you'll touch: designing scalable API platforms for millions of users, modernizing legacy into event-driven microservices, and building internal developer-experience tooling so teams deliver faster with higher quality. From observability and testability to system design and team process, you'll influence every layer of delivery. ## Related Videos - [WeAreDevelopers LIVE - GraalVM in action, Static Analysis insights and more](https://www.wearedevelopers.com/videos/1723-wearedevelopers-live-graalvm-in-action-static-analysis-insights-and-more) - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Why Kotlin is the better Java and how you can start using it](https://www.wearedevelopers.com/videos/661-why-kotlin-is-the-better-java-and-how-you-can-start-using-it) - [Moving from Java to Kotlin](https://www.wearedevelopers.com/videos/384-moving-from-java-to-kotlin) ## Related Articles - [10 Highest Paying Programming Languages 2025](https://www.wearedevelopers.com/magazine/150-10-highest-paying-programming-languages-2025) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Top in-demand programming languages to learn in 2021](https://www.wearedevelopers.com/magazine/30-top-in-demand-programming-languages-to-learn-in-2021)
