Senior Full Stack Software Engineer (Product & Infrastructure)
Position Type: Full-Time, Remote
Working Hours: U.S. Client Business Hours
About the Role
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.
What You’ll OwnFull 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
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
