Forget corporate dullness and routine. This role offers a great 50/50 balance. Half of your time will be spent technically leading, mentoring, and developing a team of 4 talented developers (no rigid administration, but rather a partner and technical role model), while the other half gives you the opportunity to design modern architecture, try new approaches, and write clean code. Your mission will be to bring vision and order to our enterprise integrations across cloud (AWS), SaaS, e-commerce, and ERP systems.

Your voice on technical debt and innovation truly carries weight here. ### Partnership with technology leaders Stay in close contact with our technology partners and vendors, influencing the joint development of our platforms. ### Global community Connect technical communities across Prague, the US, and India, opening doors to global know-how sharing. ### What you should have Background in software engineering At least 5 years of experience in development, implementation, integration, and microservices (iPaaS, API Management, SOA, Enterprise Application Integration). ### Tech stack overview Good experience with MuleSoft Anypoint Platform and a broad understanding of enterprise integration technologies, cloud platforms (AWS or Azure), APIs, and event-driven architectures (Kafka, Event Grid). ### Engineering practices Understanding of the modern software development lifecycle, CI/CD pipelines, containerization (Kubernetes), and DevSecOps practices within a regulated enterprise environment. ### English and communication Ability to clearly present technical concepts to both business and leadership, and to collaborate in an international environment (US, India). ### What we offer Exciting work in a great team, global projects, international environment Opportunity to learn and grow professionally within the company globally Hybrid working model, flexible role pattern Competitive salary & incentive pay Pension and health insurance contributions Internal reward system and referral scheme 5 weeks annual leave, 5 sick days, 15 days of certified sick leave paid above statutory requirements annually, 40 paid hours annually for volunteering activities, 12 weeks of parental contribution Cafeteria for tax free benefits according to your choice (meal vouchers, sport, culture, health, travel, etc.), Multisport Card Vodafone, Raiffeisen Bank, Foodora, and discount programmes Up-to-date laptop and iPhone Parking in the garage, showers, refreshments, massage chairs, library, music corner Ready to take up the challenge?
