xTiles is an innovative AI-powered workspace that helps users and teams transform the chaos of notes, emails, links, ideas, and tasks into clear, interconnected visual projects. Ranked among the Top 100 startups in Ukraine, we are currently hyper-focused on scaling and conquering new horizons.
We are looking for a Backend Engineer who doesn't just "code by tickets," but wants to take ownership of architectural decisions and grow alongside the product.
Why xTiles?
✦Real Impact: You'll work directly with the Product team. Your ideas have a direct path to production.
✦Legacy-Free Stack: Kotlin, Spring Boot (WebFlux), MongoDB, Redis, Elasticsearch, and NATS JetStream. We are all about reactivity and real-time synchronization.
✦Startup Culture: Minimum bureaucracy, maximum engineering freedom.
✦Global Ambition: We are building a world-class product used by creators, students, and businesses across 191 countries.
What You Will Do:
✦Design and develop microservices using Kotlin + Spring Boot (WebFlux).
✦Optimize data performance: MongoDB for storage, Elasticsearch for full-text search, and Redis for caching.
✦Build reliable event streams via NATS JetStream (focusing on eventual consistency and back-pressure).
✦Lead technical discovery phases and prepare RFCs for new features.
✦Participate in architecture reviews and share your expertise during internal tech talks.
What We Expect From You:
✦2–3+ years of experience within the JVM stack (Java/Kotlin).
✦A solid understanding of distributed systems and microservices architecture.
✦Hands-on experience with NoSQL databases (specifically MongoDB).
✦Product-oriented mindset: You care about user value just as much as code elegance.
✦Location: A desire to work in Kremenchuk and be an active part of our local office community.
You'll Fit Right In If:
✦You don't wait for a "perfect" spec—you ask the right questions to find the most efficient path to the goal.
✦You read performance metrics and dashboards as confidently as unit tests.
✦You are naturally curious, from exploring ML integrations to optimizing high-load systems.
What We Offer:
✦Collaboration with a team of true fans of their craft.
✦The chance to actually shape the product, not just close Jira tickets.
✦A flexible schedule focused on results, not hours clocked.
✦Paid vacation, sick leave, and ample opportunities for professional development.
