Senior AWS Platform Engineer

At Luscii, we are creating space for care by building digital health applications that help people manage their health. Applications such as the Luscii Thuismeten app and OMRON Connect. Together with healthcare professionals around the world, we build technology that helps users receive the right care in the right place. Millions of people rely on our products every month, and behind every reliable healthcare experience is a cloud platform that simply works. As engineer working on our apps, you will play a vital role in modernising the cloud platform that powers the platform, creating a more reliable, scalable and future-proof foundation for millions of users worldwide. OMRON Connect is one of the largest digital health platforms in our ecosystem, connecting millions of users with their healthcare data through OMRON devices. Much of the platform has grown over many years and was partly built by external partners. Today, we're investing heavily in bringing that knowledge, ownership and technical excellence in-house. This is not about replacing everything overnight. It is about making thoughtful engineering decisions, modernising step by step, and building a cloud platform that gives our engineering teams the foundations, tooling and confidence they need to deliver safely and independently. Your work will have a direct impact on the reliability, scalability and cost-efficiency of a platform serving several million monthly active users across the world. You will help shape our cloud and engineering standards, introduce modern practices where they genuinely add value, and make Infrastructure as Code, observability and safe continuous delivery the default rather than the exception. By creating reusable infrastructure, improving developer experience and removing unnecessary complexity, you will help teams move faster without compromising reliability or security. Along the way, you will collaborate with engineers, influence technical direction and leave the platform in a significantly better state than you found it. Your role You will become one of the technical driving forces behind the cloud platforms that power our digital health applications. Working closely with fellow engineers, product teams and colleagues across countries, you will help shape and improve our cloud infrastructure, strengthen the developer experience and ensure reliability, security and scalability are built into the foundations of our technology. Your exact focus will evolve with the needs of our teams and the opportunities you identify to make a lasting impact. This is a role for someone who enjoys solving difficult engineering problems without chasing complexity for complexity's sake. You will help us balance innovation with pragmatism, modernising a live healthcare platform while maintaining the stability that patients and healthcare professionals depend on every day. What you will be doing, among others: • Design, build and evolve our AWS platform using Terraform as the single source of truth, while driving the gradual modernisation of our cloud landscape; • Build reusable infrastructure, deployment pipelines and platform tooling that enable engineering teams to ship independently and safely; • Introduce pragmatic cloud-native and event-driven solutions where they genuinely improve scalability, reliability and maintainability; • Make observability a default through standardised monitoring, logging, dashboards and alerting across the platform; • Improve deployment practices with automated CI/CD, progressive delivery and reliable rollback strategies; • Embed security, compliance and cost optimisation into the platform through automated guardrails and best practices; • Coach fellow engineers, review infrastructure and application code, and raise the o
