Senior Full-Stack Engineer (Go+Vue.js)

About NRS

National Retail Solutions (NRS) is a leading provider of point-of-sale, payment, and digital solutions to tens of thousands of independent retailers across the United States and Canada. As a major player in the retail technology industry, NRS is expanding into next-generation cloud platforms, high-throughput retail ecosystems, and advanced analytics solutions.

We are building modern, highly scalable systems designed specifically for high-volume retail operations and real-time reporting. This project represents one of the most significant technical initiatives in NRS’s history and offers a rare opportunity to join at the ground floor of a major strategic expansion.

Role Overview:

We are seeking a Senior Full Stack Engineer based in Minsk, Belarus to join our distributed engineering team. In this role, you will help architect and build core components of NRS’s next-generation retail platform. You will focus heavily on robust backend services written in Golang, high-throughput query performance, and leveraging ClickHouse for real-time reporting and large-scale data modeling, alongside modern front-end architectures using Vue.js and micro-frontends

Experience with columnar/OLAP databases like ClickHouse is highly desired to support our analytical engine, but deep, hands-on mastery of SQL, data indexing, and database performance profiling is the primary requirement.

You will work closely with engineering leadership, product managers, and architects across Israel, Belarus, and the U.S., contributing meaningfully to the technical direction, data architecture, and scalability of our products.

This position requires 3 days a week in-office work at our office in Minsk to collaborate in person with local engineering peers, along with regular remote collaboration across our global teams

Responsibilities:

Technical Leadership & Architecture

Architect, build, and maintain high-performance full-stack applications—ranging from real-time analytics dashboards to reporting pipelines—with a strong focus on Golang for backend microservices and Vue.js on the front end.

Design, model, and optimize high-speed relational and analytical data stores—writing advanced SQL queries, materialized views, aggregation logic, and indexing strategies to power real-time reporting dashboards.

Leverage analytical data stores (ideally ClickHouse) to build ultra-efficient reporting engines and handle high-throughput data ingestion.

Design and implement modular micro-frontend architectures to support scalable, independently deployable UI components across team boundaries.

Take end-to-end ownership of core system components, high-throughput backend APIs, and event-driven microservices.

Drive architectural design, technical planning, query optimization, and engineering best practices across the team.

Ensure platform scalability, low latency, fault tolerance, and secure service design.

Execution & Delivery

Write clean, maintainable, highly efficient, and well-tested Go and JavaScript/TypeScript code.

Collaborate with product and engineering teams in the U.S. and locally to translate complex requirements into robust, scalable technical solutions.

Uphold code quality through thorough code reviews; we use AI-assisted tooling (Cursor, Copilot, Claude Code) as part of our workflow.

Debug, profile, and optimize complex SQL queries, execution plans, database locks, and distributed backend microservices.

Collaboration & Culture

Participate in daily standups, sprint planning, and retrospectives to support continuous delivery.

Communicate effectively across time zones and collaborate seamlessly with global engineering leadership.

Required Qualifications:

6+ years of full-stack development experience, with at least 2 years in a senior or lead capacity.

Solid Backend Expertise in Go: Proven track record of designing, building, and scaling Go-based microservices, concurrent applications, and REST/gRPC APIs.

Deep SQL Mastery & Data Modeling: Expert-level knowledge of SQL, including writing complex joins, subqueries, query execution plan analysis (EXPLAIN), indexing strategies, schema normalization/denormalization, and performance profiling for large-scale reporting datasets.

Modern Frontend & Micro-Frontend Mastery:

Strong hands-on experience with modern JavaScript/TypeScript frameworks—specifically Vue.js (Vue 3 / Composition API).

Demonstrated experience designing or working within micro-frontend architectures (e.g., Module Federation, single-spa, component isolation).

Experience building end-to-end SaaS products, microservices, or complex distributed web platforms.

Proficiency with Linux/Unix environments, Git, and CI/CD automation workflows.

Strong problem-solving mindset with the ability to lead technical initiatives independently.

Excellent English communication skills with experience collaborating with remote/U.S.-based stakeholders.

Nice to Have:

ClickHouse / OLAP Experience: Direct hands-on experience with ClickHouse or other columnar/analytical databases (Snowflake, BigQuery, Redshift) is a strong plus.

Working knowledge of PHP (legacy service integration/migration).

Familiarity with containerization and orchestration (Docker, Kubernetes).

Hands-on experience with cloud platforms (ideally AWS).

Knowledge of real-time communication technologies (WebSockets, gRPC, Kafka, or NATS).

We are pleased to offer:

• Hybrid work opportunity (3 days in the office)!

• Modern office with free parking in the very center of Minsk. 

• An exciting and challenging job with talented people around.

• Competitive salary and growth opportunities.

• Really good hardware.

• 26 vacation days & 5 fully covered sick days without sick leave required per year.

• Compensation for professional training, seminars, and conferences.

• Sports activities reimbursement and loyalty program.

• Medical insurance.

• Referral program - get rewarded for helping us grow the team with talented people.

• Company-supported English classes to enhance your professional growth.
