Are you an experienced Full Stack Developer who loves solving complex challenges , building scalable applications, and wants to shape the future of real-estate technology? Do you enjoy designing high-quality integrations and tools that are used by property managers worldwide? If the answer is yes, keep reading — this may be the perfect role for you. ABOUT US At Wunderbricks , we started our mission in 2019 to revolutionize the real-estate industry with our state-of-the-art, SaaS-based Property Management System (PMS), built on Salesforce.  Our platform empowers real-estate owners and property managers to streamline operations, automate workflows, and gain valuable insights.  Since our solution is highly customizable and connects easily with thousands of applications via Salesforce AppExchange, we continuously innovate and improve our product for a growing base of domestic and international mid- to high-end customers. We are not looking for average — we look for those who love serious challenges, strive for quality, and have the drive to build products that truly matter. We value trust, empathy, ownership, learning, and a healthy work-life balance. As a Full-Stack Developer , you will own the Release Management Platform - a web application that connects to customer Salesforce orgs, detects their installed package version, and guides administrators through every post-upgrade step from their current version to the latest. You will design and build both the customer-facing wizard and the internal publisher tool used by the Wunderbricks team to author and deploy each release. WHAT YOU WILL DO Design and build the customer-facing upgrade wizard : OAuth 2.0 + PKCE authentication, version detection, and automated step execution via Salesforce Tooling and Metadata APIs. Build the internal release publisher : step authoring, Apex script management, diagram annotations, and the publish workflow that pushes new versions to all customer orgs. Implement automated upgrade steps — validation rule deactivation, anonymous Apex execution, and metadata deployments — directly via Salesforce REST APIs. Develop the package installation and extension management module, including dependency enforcement across the Wunderbricks extension ecosystem (Exact Online, BAG, AFAS, WWS, Inspection App, and more). Design and maintain the release data model and backend API: step definitions, completion state, script storage, and per-org audit logging. Write and maintain infrastructure : hosting, CI/CD, database, and monitoring on a managed cloud platform. Collaborate with the product and Salesforce development teams to align platform releases with product roadmap cycles. WHAT YOU BRING 4–7+ years of full-stack development experience with a track record of shipping production applications. Hands-on experience integrating with the Salesforce REST, Tooling, or Metadata APIs from outside Salesforce — web applications that call Salesforce as an external service, not internal Apex or LWC development. Solid knowledge of OAuth 2.0 flows — in particular Authorization Code + PKCE for client-side applications. Strong proficiency in modern JavaScript / TypeScript , comfortable owning both a frontend (React or equivalent) and a Node.js backend. Experience with backend API development : REST API design, PostgreSQL or equivalent, and file storage. Comfortable with infrastructure basics : deploying to managed platforms, setting up CI/CD, and monitoring. Ability to translate complex technical requirements into clean, maintainable solutions without over-engineering. Strong ownership mentality — the platform ships on every product release cycle (6-8 weeks); you treat that cadence as your own deadline. Excellen
