The pod will deliver against two parallel workstreams: net-new feature engineering on the Java 21 / Spring Boot 3 platform, and the Salesforce-to-microservices data and capability migration.

You will write the team's ADRs and design docs</li></ul><p><strong>Desirable:</strong></p><ul><li>Direct experience with Salesforce data extraction and migration to a relational target</li><li>Working experience with AI agent frameworks — LangGraph, LangChain, CrewAI, or comparable</li><li>Logistics, supply chain, B2B marketplace, or WMS / TMS domain background</li><li>Prior technical-lead role in a Series B–C scale-up that grew from 5 to 50+ engineers</li><li>Open-source contributions or technical writing that demonstrate the engineering bar</li></ul><p><strong>What`s in it for you?</strong></p><ul><li>Strong community: Work alongside top professionals in a friendly, open-door environment</li><li>Growth focus: Take on large-scale projects with a global impact and expand your expertise</li><li>Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications</li><li>Endless opportunities: Explore diverse domains through internal mobility, finding the best fit to gain hands-on experience with cutting-edge technologies</li><li>Care: We’ve got you covered with company-paid medical insurance, mental health support, and financial & legal consultations</li><li>Flexibility: Balance office and remote work to fit your rhythm</li><li>Our Offices in the Czech Republic: We have three offices in Prague, Hradec Králové, and Zlín.
