Role Summary

Senior Full Stack Software Engineer (Product & Infrastructure)
Position Type: Full-Time, Remote
Working Hours: U.S. Client Business Hours

We’re hiring a Senior Full Stack Software Engineer to build, scale, and maintain modern web applications and cloud infrastructure across high-impact product environments.

This is a hands-on engineering role for someone who can own features end-to-end — from front-end user experience to back-end architecture, APIs, databases, deployments, and infrastructure reliability.

You’ll work closely with product, design, and engineering teams to ship scalable applications that are performant, secure, and built for long-term growth.

This role goes beyond simply writing code. You’ll contribute to technical architecture, improve engineering processes, mentor junior developers, and help shape the reliability and scalability of the platform as the company grows.

If you enjoy building production-grade systems, solving infrastructure challenges, and shipping features quickly without compromising quality, this role is for you.

Responsibilities

Full Stack Product Development

Build and maintain scalable web applications using React, Next.js, Angular, or Vue

Develop secure and performant back-end services using Node.js, Python (FastAPI, Django, Flask), or similar frameworks
Design and build RESTful and GraphQL APIs
Translate Figma or product requirements into responsive, production-ready interfaces
Optimize front-end performance, accessibility, and user experience across devices

Database & System Architecture

Design scalable database schemas using PostgreSQL, MySQL, or MongoDB

Write efficient queries and optimize application performance
Build systems that support scalability, maintainability, and reliability
Contribute to architecture decisions and long-term technical planning

Infrastructure, DevOps & Cloud Deployment

Deploy and manage applications on AWS, GCP, or Azure

Build and maintain CI/CD pipelines using GitHub Actions, Jenkins, CircleCI, or similar tools
Containerize applications using Docker and manage deployments through Kubernetes or serverless infrastructure
Monitor uptime, logs, and system health across environments

Testing, Reliability & Security

Write unit, integration, and end-to-end tests using Jest, Cypress, PyTest, or similar tools

Maintain strong testing standards and high code quality
Implement secure authentication, authorization, and API best practices
Follow modern security standards including OWASP best practices and secure infrastructure design
Troubleshoot outages, performance bottlenecks, and production issues proactively

Technical Leadership & Collaboration

Participate in architecture reviews and technical planning discussions

Review pull requests and mentor junior engineers through code feedback and collaboration
Work closely with product managers and designers to refine requirements and technical feasibility
Help improve engineering workflows, standards, and development processes

What Makes You a Great Fit

You can independently ship features from concept to deployment

You understand both application development and infrastructure reliability
You balance speed, scalability, and code quality effectively
You enjoy solving complex technical problems in production environments
You communicate clearly and collaborate well across teams
You take ownership of outcomes, not just tickets

Required Experience & Skills

5+ years of professional full stack software engineering experience

Strong proficiency with JavaScript/TypeScript, React, and Node.js
Experience with relational databases (PostgreSQL, MySQL) and NoSQL databases (MongoDB)
Experience deploying and managing applications in AWS, GCP, or Azure
Strong understanding of APIs, authentication, and scalable application architecture
Experience with CI/CD pipelines and Git workflows
Strong debugging, optimization, and problem-solving skills
Excellent written and verbal English communication skills

Requirements

Preferred Experience

Experience leading architecture discussions or technical design reviews

Infrastructure-as-Code experience (Terraform, Pulumi, CloudFormation)
Background working on SaaS products or high-traffic web applications
Experience with Docker, Kubernetes, or serverless architectures
Familiarity with microservices and event-driven systems
Experience monitoring production systems using Datadog, Grafana, Prometheus, or similar tools
Exposure to performance optimization and cloud cost management

What a Typical Day Looks Like

A Senior Full Stack Engineer’s day revolves around building features, improving infrastructure, and maintaining system reliability. You will:

Participate in standups and technical planning discussions
Build front-end interfaces and back-end APIs for new product features
Review and merge pull requests while mentoring junior developers
Debug production issues and optimize application performance
Deploy updates through CI/CD pipelines and monitor infrastructure health
Collaborate with product and design teams to refine workflows and user experience
Improve testing, scalability, and long-term maintainability of the platform

In short: you are responsible for building reliable, scalable, and production-ready software systems that directly support business growth.
