Senior Full-Stack Engineer

We're looking for an experienced Senior Full-Stack Engineer who can take ownership of complex features, make sound technical decisions, and contribute across both frontend and backend development.
You'll work on production applications and client projects using modern JavaScript, TypeScript, backend, database, and cloud technologies — contributing throughout the development lifecycle, from technical planning and architecture to implementation, code reviews, testing, deployment, and ongoing maintenance.
This role suits an engineer who is comfortable working independently, solving complex technical problems, collaborating with distributed teams, and taking ownership of features from initial planning through production.
Because this is a U.S.-based remote position, applicants must currently reside in the United States and be available during U.S. business hours.

Develop modern frontend applications using React, TypeScript, and related technologies
Build and maintain backend APIs and services using Node.js, Python, or comparable technologies

Develop and integrate REST APIs and third-party services
Participate in application architecture and technical planning
Translate product and business requirements into practical technical solutions
Write clean, maintainable, and well-tested production code
Review pull requests and provide constructive technical feedback
Debug complex production issues and implement long-term solutions

Work with cloud platforms and production deployment environments
Contribute to CI/CD pipelines and development workflows
Collaborate with product managers, designers, engineers, clients, and company leadership
Help establish engineering standards and development best practices
Mentor junior and mid-level engineers when needed
Communicate technical decisions clearly to both technical and non-technical stakeholders
Qualifications
5+ years of professional software engineering experience, including significant full-stack development experience
Strong professional experience with React and modern frontend development
Strong experience with TypeScript and JavaScript
Professional backend development experience with Node.js, Python, or comparable technologies
Good understanding of REST API design and backend architecture
Professional experience with PostgreSQL, SQL, or other relational databases

Ability to independently investigate and solve complex technical problems
Good written and spoken English communication skills
Ability to communicate clearly and collaborate effectively in a remote environment
Reliable high-speed internet connection
What we're looking for
Someone who goes beyond simply completing assigned tickets. You're comfortable understanding the broader product and technical context, identifying potential issues early, proposing practical solutions, and owning your work from development through production.
You balance technical quality with practical business requirements, and make thoughtful engineering decisions without overcomplicating solutions.
Because Nexorlio works across different products and client projects, you're also comfortable adapting to changing requirements, technologies, and project environments.
