Scaling & Production Engineer (f/m/d)

About ustrustscored is on a mission to make trust measurable. We're building the infrastructure that turns reputation and reliability into something transparent and verifiable — and we're doing it from scratch, the fun way.We're part of the startup hub at the HU Berlin incubator: a building full of small teams building ambitious things from zero. Our team is small and agile, decisions happen fast, and there's no layer between you and the product. If you want real responsibility from day one — not tickets handed down from three levels above — this is that job.The roleWe're moving from "it works" to "it works under load, for real users, without burning money." You'll own that transition. Your job is to make our backend stable, scalable, observable, and cost-efficient as usage grows — especially around our AI/LLM-based pipelines.What you'll doBuild and evolve systems so they stay stable under load and can be extended sensibly as the product growsRun the backend under realistic conditions: APIs, workers, task queues, Redis, databases, caching, and asynchronous processingOwn deployment and infrastructure: Docker, cloud infrastructure, CI/CD — ideally with Kubernetes or comparable setupsKeep performance and costs under control: understand early which processes get expensive at scale, where caching pays off, and how to avoid unnecessary spend as usage grows — this matters a lot with LLM-based systemsBuild the feedback loops that make all of this possible: logging, monitoring, tests, and benchmarks. Not just noticing that something is slow or unstable, but finding out whyWhat we're looking forHands-on experience running backend systems in production, not just building themSolid understanding of async architectures: workers, queues, caching layers, database performanceExperience with Docker, cloud infrastructure, and CI/CD pipelines; Kubernetes (or similar) is a plusA debugging mindset: you dig until you find the root causeAwareness of cost dynamics in AI/LLM systems, or the curiosity to build it fastDon't tick every box? If you haven't done scaling and production engineering at depth yet, but you've shipped many technical projects of your own, are extremely hands-on, and have shown you can work your way into complex topics fast — we want to hear from you too.The conditions (please read before applying)Start date: 01.08.2026, full-time. This is fixed and not flexible.The position is funded through the Berlin Startup Scholarship: €2,500/month per personYou must be registered in Berlin (Anmeldung) and have fully cleared visa/work status in Berlin at the time of applicationWhy joinYou'll be one of the first engineers shaping how trustscored runs in production — the architecture decisions you make now will carry the company. You'll work in a tight, ambitious team inside the HU Berlin incubator, surrounded by founders building from scratch, with short paths, honest feedback, and a lot of ownership.How to applySend us a short email, elaborate your motivation in 2-3 sentences, mention your superpower, what you would like to bring to the team, what you would like to learn, something you are currently learning in your life, links to things you've built (GitHub, projects, anything live), and why this role fits you.
