Role summary

We are seeking a Lead Full-Stack Engineer to join our distributed engineering team. This role will focus on building and scaling the Point of Sale platform for restaurants. Responsibilities include owning the architecture and delivery of new restaurant-facing services, from data models to APIs and user interfaces. You will also extend and harden existing production services, ensuring correctness under concurrency and handling offline capabilities. The ideal candidate has 8+ years of full-stack experience, deep Node.js and TypeScript expertise, strong relational database skills (Postgres/MySQL), and experience with message queues and real-time interfaces. Experience with Vue.js, REST API design, microservices, CI/CD, Linux, and AI tooling is also required. This is a hybrid role based in Minsk, Belarus.

We are seeking a Senior 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 - 3 days/week in the office)!

What you will own:

Architecture and delivery of new restaurant facing services, from data model to API to the screens merchants actually touch.

The merchant facing restaurant surfaces: kitchen display and everything staff touch across the life of an order.

Extending and hardening existing production services without destabilizing them.

Correctness under concurrency: transactional integrity, isolation levels, idempotency, race conditions, retries, and honest tradeoffs where perfect guarantees are not available.

Behavior 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 split.

Queueing and asynchronous processing, background jobs, and event driven flows.

Safe rollout of releases that reach tens of thousands of users.

Working directly with product managers and designers to shape what gets built, not just receiving requirements and implementing them.

Technical 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:

6-8+ years building full-stack products, including time as the senior person on the work.

Deep Node.js and TypeScript experience across the full-stack, with production services you designed and still stand behind.

Deep understanding of REST API design and microservices.

Strong 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 invalidation.

Experience 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 lag.

Front- end skill that matches the environment: our team 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 apps.

Real time interfaces built on websockets, ideally socket.io. Order flow and kitchen display depend on it.

Excellent debugging. You can take an unfamiliar production failure and reason your way to root cause instead of guessing.

Parts of the existing platform are PHP.
Working effectively in unfamiliar code, with AI, is part of this job.

Experience deploying services that scale horizontally, tolerate a failed instance or a slow dependency, and automatically add or shed capacity.

Comfortable on Linux, and fluent with Git and CI and CD workflows.

Excellent 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 reviews.

You 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 else.

You 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 guide.

You 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 staff.

You 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.
