Senior Software Engineer - Platform & Infrastructure (f/m/d)

The product you will work onThe HOLOPLOT Matrix Array is a new type of sound system built around precise, software-defined control of sound in three dimensions - grounded in physics and implemented through a combination of custom hardware and purpose-built software. HOLOPLOT deployed Matrix Arrays in various venues, including the Sphere in Las Vegas - the world’s most advanced entertainment venue and, notably, home to the world’s largest audio installation in entertainment.  Audio processing in HOLOPLOT systems is distributed: every loudspeaker runs embedded Linux, and hundreds of them have to be configured, coordinated, monitored, and updated as one system. This is enabled by multiple open source and in-house developed services running on an on-premises Kubernetes cluster. AWS-hosted services connect venues to remote monitoring, telemetry, and configuration. Many venues are air-gapped or only intermittently connected for remote servicing, and that constraint shapes most of the design decisions in the platform. The ideal candidate isWe are looking for a Senior Software Engineer who builds the platform our sound systems run on, and who takes responsibility for how it behaves in production. This is a software engineering role first. You will spend your time writing software, either with your own team or embedded with one of the other HOLOPLOT teams: services, controllers, agents, and tooling that provision, configure, observe, and update our systems. Our infrastructure is defined as code and evolves through the same review and release process as the rest of our software. You design the operational side, you build it, and you are on call when it misbehaves in the field. Your role and responsibilitiesYou will join the team that owns the platform underneath our installations and connected services, working alongside backend, embedded, and frontend engineers who are organized in cross-functional product teams. Build the platform Architect and implement services to provision, configure, and manage server fleets across AWS and local clusters. Create control-plane logic for venue systems to ensure consistency, health monitoring, rollout management, and recovery, even during uplink disruptions. Establish end-to-end provisioning workflows for embedded Linux hardware, spanning from initial manufacturing to customer deployment. Enhance update processes to streamline software deployments for active customer installations. Develop APIs and developer tooling that empower engineering teams to independently deploy, observe, and troubleshoot their services. Embed telemetry capabilities into the platform to facilitate remote diagnosis of venue system behavior . Run what you build Own the AWS infrastructure behind our connected services: remote access, access control, telemetry ingestion, remote backup, secret management, and monitoring. All of it is infrastructure as code. Operate and evolve the on-premises Kubernetes footprint at venues, including air-gapped and intermittently connected installations. Monitor large environments, investigate problems across the software/hardware boundary, and turn each incident into a fix in the code. Be part of a compensated on-call rotation Set the technical direction Advise and collaborate with product teams on building distributed systems that are scalable, secure, and observable, and review their designs with production reality in mind. Research and introduce tools and technologies where they measurably improve how we build and operate. Contribute back to the open-source projects we depend on, through issues and fixes. What you need to succeed in this roleSeveral years of professional software engineering experience, most of it spent designing and shipping production systems. Fluency in software engineering as a craft: concurrency, error handling, testing, and designing APIs that other teams build on. Working knowledge of the Kubernetes control plane and the operator/controller patter
