Software Engineer (gn) @ Stealth AI Venture, Berlin

What we're buildingFactories run on machines that generate huge amounts of data, and almost none of it gets used. We're changing that. We build AI software that turns machine and operational data into knowledge people can act on: for troubleshooting, for decisions, and for automation.We're early and in stealth. Our two founders both held C-level roles at leading German robotics ventures. They have spent years bringing advanced technology onto real shop floors, and now they're hiring the founding team.The roleYou'll build the software that makes sense of what happens on a manufacturing floor. That includes sensor measurements, actuator states, quality measurements, and operational events, streamed from connected machines and autonomous systems. Our platform processes this data to power analysis and automated workflows.We work AI-first. Our coding agents know our platform and our engineering practices, and you'll use them every day. You're still the engineer, though. You'll review every line, understand what it does, and test it properly. That frees you to focus on the application, the industrial domain, and the quality of the system.We care about what you can show, how fast you learn, and whether you take ownership. Seniority and years of experience matter less.What you'll doOwn features end to end: understand the problem, choose the approach, then build, test, ship, and follow upGet to know the existing codebase in depth, including its architecture, dependencies, data flows, and failure modesWrite code with AI tools and review each change line by line for correctness, maintainability, security, and impact on the wider systemBuild meaningful unit, integration, and end-to-end tests and wire them into CITest against messy real-world data, using recorded streams, representative datasets, and simulated devices. Cover missing or delayed measurements, duplicate or out-of-order events, invalid values, and dropped connectionsReproduce failures, fix them, and add regression tests so they don't return. Make sure tests reflect the intended behavior, and challenge the assumptions in the implementationBuild and improve backend services, APIs, and data pipelines for industrial analytics, knowledge retrieval, and automated workflowsLearn how our users and their factories work, so you can spot the right improvements and make good engineering callsHelp wherever it's needed: integration, deployment, documentation, and technical investigation. Flag progress, capacity, trade-offs, and blockers earlyYou might be a fit if youWrite strong, practical Python and understand the advanced features and patterns used in production codeHave built and maintained substantial software: finding your way in an existing codebase, debugging behavior you've never seen before, and shipping reliable changesThink like a tester: you turn requirements into test cases, set sensible test boundaries, build useful test data, and dig into failuresHave solid fundamentals in software design, APIs, data handling, testing, debugging, and version controlCan explain what code does, why it works, where it could break, and how to verify it, including code an AI helped writeLike AI coding tools, use them a lot, and stay critical of their output, because you own the resultBreak down unfamiliar problems, investigate on your own, and ask sharp questions when you need toFind the next useful step yourself and keep moving without being told what to doAre comfortable with shifting priorities, varying workloads, and a broad scope, and communicate and prioritize clearlyWrite and speak clear EnglishA degree is optional. We care about evidence that you can engineer, not about a title or a specific path.Bonus pointsDepth in one of these areas makes you a particularly strong candidate. We don't expect all three.ML and industrial data: strong ML fundamentals and hands-on work with time-series, sensor, machine, or robotics data. You've dealt with data quality, evaluated models, and turned results into useful product behaviorAgents, autonomous systems, and industrial automation: agent coordination, workflow orchestration, state management, or failure handling. IIoT experience, such as telemetry pipelines, device interfaces, MQTT, or OPC UA, is a big plusKnowledge graphs and retrieval: knowledge representation, graph database design, schema and relationship modeling, graph queries, or retrieval that connects structured knowledge to what the application needsAlso useful: cloud deployment, containers, and testing software against simulators or physical devices.Why nowYou'll be one of the first engineers. Your code goes to production, and your decisions shape the product and how we build it. You'll work directly with the founders from day one. We'll tell you more about the company, the founders, and our backers in the first conversation. Find more English Speaking Jobs in Germany on Arbeitnow
