Jobbeschreibung

About us

At VisioLab, we’re building the fastest AI-driven checkout experience in the world. No barcodes, no friction, just instant product recognition running directly on iPads.
Our software powers visual self-checkouts in high-traffic environments like corporate dining halls, student canteens, and some of the largest sports and entertainment venues in the US, Europe and Australia. We’re live with clients across the NBA, NFL, and MLS, delivering seamless self-service to tens of thousands of guests every game day.
Founded in 2019 and backed by top-tier investors, we’re a growing team of engineers, operators, and designers working across Europe and the US. We ship fast, learn in the field, and turn cutting-edge AI into everyday convenience.

The role

As a Fullstack Engineer at VisioLab, you'll play a critical role in shaping the product experience at the core of our AI checkout platform. This is not a maintenance role. It’s a build role. You’ll be working in a fast-growing startup where speed, ownership, and technical excellence are the default.

You'll join a lean, focused tech team and take full ownership of features that go live across some of the most demanding real-world environments, from major US stadiums to high-volume foodservice venues. You’ll help us evolve our entire product stack, from the customer-facing interface to backend systems that orchestrate real-time computer vision and payment flows.

Our architecture is built on modern, serverless infrastructure. That means no legacy systems, no outdated tech debt. Just the chance to move fast, ship clean, and focus on building powerful features that directly impact user experience and business growth.

What you'll do

• Scale the Platform: Help evolve our core product architecture to support global rollout across thousands of high-traffic locations. Your work will directly impact performance, reliability, and ease of deployment
• Build Enterprise-Ready Features: Design and deliver scalable self-service tools, admin dashboards, and workflows that serve both end-users and enterprise operators. You’ll create features that balance flexibility with simplicity and work out-of-the-box in real-world conditions.
• Integrate with Global Ecosystems: Connect our platform with third-party APIs for loyalty programs, inventory management, reporting, and more. You’ll design integration layers that are modular, reliable, and built for scale.
• Shape Technical Direction: Stay current on modern frameworks, serverless infrastructure, and fullstack best practices. You’ll bring new tools, patterns, and perspectives into the team and help define how we build as we grow.
• Own What You Ship: From design to deployment, you’ll take full ownership of your work, ensuring it meets the high standards our clients and users expect and iterating quickly based on real-world feedback.
• Tech that moves fast—like you. Build with TypeScript, React, and Next.js on the frontend. Power it all with Firebase and GCP on the backend. Ship fast using GitHub, design in Figma, and stay synced via Slack and Google Workspace.

What you'll bring

• Deep Expertise & React: You have substantial experience building production-grade applications with React and Next.js.
• Serverless Experience: You understand the patterns, limitations, and best practices of serverless architectures and NoSQL databases (specifically Firestore or MongoDB).
• Product Mindset: You can take a rough feature requirement and turn it into a shipped solution without needing pixel-perfect hand-holding.
• Communication: You speak German and English fluently and possess excellent communication skills.
• Location: You are based in (or willing to commute to) one of our German offices (Berlin or Osnabrück) for regular collaboration days.

What We Can Offer You

• Build, Don’t Just Maintain: Join a phase of rapid expansion where you are architecting new features, not just patching legacy code.
• Verified Product-Market Fit:Work on a product that is already live and demanding global scalability.
• Autonomy by Default:We hire experts and trust them to make technical decisions without micromanagement.
• Rapid Career Growth:Join at the inflection point of our global expansion, where your personal growth tracks directly with company success.
• A Seat at the Table: As a Fullstack Engineer, your input will directly shape the product roadmap and engineering culture.
• Developer experience: We equip you with powerful hardware and the latest developer tools (from AI agents to custom keyboards) so you can focus on shipping.
