Lead Full-Stack Engineer

We are seeking a Lead Full-Stack Engineer to join our distributed engineering team. IDT/NRS builds the Point of Sale platform that runs tens of thousands of independent retail stores across the United States. We are now expanding that platform into restaurants. If you like challenges where the hard part is getting it right at scale rather than getting it working once, this is that job! Primary location - Minsk, Belarus (hybrid)! What you will own: Architecture and delivery of new restaurant facing services, from data model to API to the screens merchants actually touchThe merchant facing restaurant surfaces: kitchen display and everything staff touch across the life of an orderExtending and hardening existing production services without destabilizing themCorrectness under concurrency: transactional integrity, isolation levels, idempotency, race conditions, retries, and honest tradeoffs where perfect guarantees are not availableBehavior when the connection drops. A store keeps serving whether or not the network is up, which means offline capable clients, local state, sync on reconnect, and reconciling what happened while the system was splitQueueing and asynchronous processing, background jobs, and event driven flowsSafe rollout of releases that reach tens of thousands of usersWorking directly with product managers and designers to shape what gets built, not just receiving requirements and implementing themTechnical direction and code review for other engineers, including the judgment to say when a design is wrong and the credibility to make that stick Required Qualifications: 8+ years building full-stack products, including time as the senior person on the workDeep Node.js and TypeScript experience across the full-stack, with production services you designed and still stand behindDeep understanding of REST API design and microservicesStrong relational database skills, Postgres or MySQL: schema design, indexing, query tuning, transactions, and what actually happens under load. Comfort with non relational stores such as Redis or MongoDB, and with caching and invalidationExperience with queues and streaming, whether Kinesis, Kafka, RabbitMQ, SQS, BullMQ, or similar, including the failure modes that come with them: ordering, duplicates, replay, and consumer lagFront- end skill that matches the environment: Restaurant staff use these screens during a rush, on a terminal or a tablet, with no time to think and no tolerance for a bad interaction. We use Vue. Experience with React or Angular is fine, as long as it includes component architecture, state management, and progressive web appsReal time interfaces built on websockets, ideally socket.io. Order flow and kitchen display depend on itExcellent debugging. You can take an unfamiliar production failure and reason your way to root cause instead of guessingParts of the existing platform are PHP. Working effectively in unfamiliar code, with AI, is part of this jobExperience deploying services that scale horizontally, tolerate a failed instance or a slow dependency, and automatically add or shed capacityComfortable on Linux, and fluent with Git and CI and CD workflowsExcellent written and spoken English. You will be in daily conversation with teams in the United States and Israel, and will often be the person explaining a technical decision to people who did not attend the design discussion How you work: AI first. You use AI tooling as a core part of how you engineer: mapping an unfamiliar codebase in hours instead of weeks, pressure testing your own designs, moving faster without lowering the bar. You apply it across the whole lifecycle: shaping a design before any code exists, writing and refactoring, reviewing your own work, as well as automated PR reviewsYou jump in. Handed a large, complex, unfamiliar repository, your instinct is to open it and start reading. Complexity and sensitivity are reasons to be careful, not reasons to wait for someone elseYou build services that stay maintainable. Clear boundaries, readable code, tests that earn their keep, observability that makes production legible. The next engineer should be able to operate what you built without a tour guideYou think about the person on the other side. During a rush, a confusing screen or one extra tap is not a cosmetic problem. It is a slower line and a worse night for the staffYou go the extra mile. You follow a problem to its actual end, including the parts nobody assigned to you. You take pride in the work and you care how it lands for the merchant on the other side of the screen What We Offer: Remote b2b (Georgia)!Hybrid/On-site/Remote in Belarus and Moldova work opportunity!Stable job with long-term growth perspectiveCompetitive salary with annual performance reviewTop-tier hardware to support your productivityAn exciting and challenging job with talented people aroundContinuous learning and career growth opportunitiesCompensation for professional training, seminars, and conferencesReferral program - get rewarded for helping us grow the team with talented peopleCompany-supported English classes to enhance your professional growthMore perks for the Minsk and Chisinau office employees About us: IDT Corporation is a global communications company founded in 1990 and headquartered in Newark, New Jersey.
