We create campaigns, websites, apps and other digital solutions for inspiring brands all over the world.\nAt our Technology department, we are super proud of the complex digital solutions we build for telcos, lottery companies and aviation brands all over the world. Right now, we’re looking for a seasoned Node.js pro to grab the wheel and take the lead on mission-critical, customer-facing applications: someone who speaks Fastify fluently, thrives on designing and scaling high-load API gateways, and knows exactly how to keep production from crashing into an infinite loop.\nRequirements\nYour tasks will be:\nDeveloping high-quality software to achieve goals in a fast-paced business environment.\nUsing Node.js and Fastify to deliver core functionality, designing and maintaining high-load API gateways.\nMentoring developers and fostering a culture of technical excellence within your team.\nSyncing regularly with business stakeholders to seamlessly align technical architecture with business objectives (translating developer wizardry into real-world business talk). \nTaking part in incident resolution and problem management.\nParticipating in technical design and change management.\nContributing to architectural and design decisions.\nEstimating development and delivery times based on documented requirements, specifications, and technical designs (crystal balls are welcome, but realistic timelines work even better). \nWriting unit and integration tests, participating in end-to-end test development.\nWorking together with our in-house DevOps team to streamline and sustain a well-functioning CI/CD pipeline.\nEnsuring PCI/DSS compliance for the code you deliver with your team.\nDiscussing technical solutions with other developers\nParticipating in your peers’ code reviews.

This is an international community where documentation and formal communication are in English (if something’s wrong, you can curse in Hungarian, that sounds way better).\nWe will be super happy if you:\nHave familiarity with the .NET ecosystem and can comfortably read and understand C# code.\nHave hands-on experience with PCI/DSS or you already have an OWASP certification.\nAre familiar with the Agile methodology and SAFe principles.\nBenefits\nWhat We Offer\nHybrid Work & Flexible Location\nWork from home when needed, enjoy our comfortable downtown Budapest office, or work from abroad for a while-as long as you have a stable internet connection.\nModern Office Environment\nMacBooks, great coffee, fresh fruit, and a pleasant, well-equipped workspace.\nFlexible Benefits & Health Package\nA personal benefits budget for sports, education, or commuting, plus annual access to routine and preventive health screenings.\nExtra Days Off for Loyalty\nOur Level Up system rewards long-term commitment with up to 5 extra paid days off per year.\nContinuous Learning & Growth\nOpportunities to attend conferences, take part in coaching and hackathons and share your expertise.
