Design, build, and operate end-to-end features across a React frontend and Node.js/TypeScript backend. Implement secure, performant APIs, model and optimize PostgreSQL data, deploy and monitor services on AWS, improve engineering standards through code reviews and testing, troubleshoot production issues, and contribute to scalable system architecture in a distributed team.
## About Xpert Development
Xpert Development is a fast-growing tech company building modern, scalable web applications for customers around the world. We value pragmatic engineering, strong ownership, and thoughtful collaboration across product and engineering.
## Role Overview
As a Senior Full Stack Engineer, you’ll design and build end-to-end features across our React frontend and Node.js/TypeScript backend. You’ll work closely with product and engineering teammates to deliver reliable, scalable experiences, contribute to architectural decisions, and raise the bar on code quality and operational excellence in a globally distributed environment.
## What You’ll Do
* Build and ship full-stack features using React, Node.js, and TypeScript
* Design and implement APIs and services that are secure, performant, and maintainable
* Model and optimize data in PostgreSQL; write efficient queries and migrations
* Develop and operate cloud infrastructure on AWS (deployment, monitoring, scaling)
* Collaborate with product/design to translate requirements into well-scoped technical plans
* Improve engineering standards through code reviews, testing practices, and documentation
* Troubleshoot production issues and drive root-cause fixes and preventative improvements
* Contribute to system architecture decisions with a focus on scalability and reliability
## Required Qualifications
* 5+ years of professional software engineering experience (full stack preferred)
* Strong experience building web UIs with React (hooks, state management, performance)
* Strong backend experience with Node.js and TypeScript (API design, service patterns)
* Hands-on experience with PostgreSQL (schema design, indexing, query optimization)
* Experience deploying and operating applications on AWS
* Solid understanding of software engineering fundamentals (testing, debugging, design patterns)
* Ability to work effectively in an international, distributed team (clear written communication, ownership mindset)
## Nice to Have
* Experience with CI/CD pipelines and infrastructure-as-code (e.g., Terraform, CloudFormation)
* Experience with observability tooling (logging, metrics, tracing) and incident response
* Experience with containerization and orchestration (Docker, ECS/EKS, Kubernetes)
* Familiarity with security best practices (authn/authz, OWASP, secrets management)
* Experience mentoring engineers and leading technical initiatives
## Tech Stack
* Frontend: React
* Backend: Node.js, TypeScript
* Database: PostgreSQL
* Cloud: AWS
## Location
International (remote-friendly). Collaboration happens across time zones, with an emphasis on async communication and well-documented decisions.
## What Success Looks Like
* You deliver high-quality features end-to-end with minimal rework and strong attention to detail
* You proactively identify performance, reliability, and scalability risks and address them early
* You improve team velocity through clear technical plans, strong code reviews, and pragmatic tooling
* You help shape architecture and engineering practices as the product and team scale
