Full-Stack Engineer (Python / React / AWS)

Remote | Long-Term Contract


Overview


A well-established, high-performing engineering organization is seeking a Full-Stack Engineer to contribute to a large-scale, business-critical internal platform. This system supports core operational workflows and requires a strong emphasis on code quality, maintainability, and ownership.


This is an opportunity for an engineer who approaches development with a systems mindset, understands the broader business context of their work, and is comfortable operating within a complex, mature codebase.


Key Responsibilities


  • Develop and enhance a large-scale application using Python, React, and AWS across the full stack
  • Work within an existing architecture that includes complex business rules and interdependent components
  • Write clean, maintainable, and scalable code aligned with established engineering standards
  • Ensure strong testing practices, including comprehensive unit test coverage
  • Collaborate closely with engineering peers, architects, and cross-functional stakeholders
  • Troubleshoot and resolve issues by evaluating system behavior holistically (data flow, performance, dependencies)
  • Take ownership of features end-to-end, including design, implementation, testing, and long-term support
  • Contribute to ongoing improvements in system design, performance, and reliability


Required Qualifications


Technical Skills:

  • Strong experience with Python in production environments
  • Proficiency with React and modern JavaScript (TypeScript preferred)
  • Hands-on experience with AWS services
  • Solid understanding of REST APIs and distributed system design
  • Experience with unit testing frameworks and disciplined testing practices
  • Familiarity with CI/CD pipelines and modern development workflows
  • Experience working within complex, highly customized systems


Engineering Mindset:

  • Strong emphasis on writing high-quality, maintainable software—not just functional code
  • Ability to understand and apply business logic within technical solutions
  • Detail-oriented with a focus on scalability and long-term impact
  • Comfortable working within an established codebase and contributing incrementally
  • Strong communication and collaboration skills
  • Demonstrated problem-solving ability in complex technical environments


Preferred Experience:

  • Exposure to enterprise-grade or highly customized platforms
  • Experience with microservices, event-driven, or serverless architectures
  • Background in environments with strict quality or testing standards
  • Familiarity with systems involving pricing, configuration, or workflow-heavy logic
  • Experience with algorithmic problem solving or structured technical interview environments


Additional Details:

  • Fully remote position
  • Long-term engagement with potential for full-time conversion
  • Multi-stage technical interview process with a focus on problem-solving and engineering fundamentals


Why Consider This Opportunity:

  • Work on a platform with direct operational and business impact
  • Join a team that prioritizes engineering discipline and code quality
  • Collaborate with experienced engineers in a highly accountable environment
  • Opportunity to influence and improve a complex, high-value system
