Senior Site Reliability Software Engineer at Shell Recharge
Amsterdam, North Holland, Netherlands
Summary
👤
SeniorGertjan Assies is a Senior Site Reliability Software Engineer based in Amsterdam with 11+ years of experience designing and operating cloud-native, reactive and functional systems. He combines hands-on coding (Scala, Java, .NET) with leadership roles—tech lead, scrum master, product owner and DevOps team lead—preferencing to spend the majority of his time architecting and shipping code. Deep expertise in AWS, Akka-based distributed streaming, microservices and automation underpins his approach to making infrastructure “boring, reliable and scalable.” He’s polyglot curious, with practical excursions into Elixir, Go, Clojure, Haskell and low-level languages, reflecting a pragmatic belief that tools are means to an outcome rather than dogma. At Shell Recharge and NewMotion he focused on stability, security and performance while “coding himself out of any situation,” showing a bias for automation and durable engineering. His background in product ownership and personalization features gives him an uncommon eye for aligning platform reliability with real product needs.
