What does a senior React Native engineer do?

A Senior React Native Engineer is responsible for designing, developing, and maintaining mobile applications using the React Native framework. They lead technical decisions, write high-quality code, and ensure seamless integration with backend services. Additionally, they mentor junior developers, collaborate with cross-functional teams, and help define best practices for code quality and app performance. Their expertise enables companies to create robust, scalable, and user-friendly mobile experiences for both iOS and Android platforms.

To thrive as a Senior React Native Engineer, you need advanced proficiency in JavaScript, React Native, mobile app architecture, and a strong understanding of both iOS and Android platforms, often supported by a degree in computer science or related experience. Familiarity with tools like Redux, TypeScript, RESTful APIs, and CI/CD systems, as well as experience using testing frameworks such as Jest or Detox, is typically required. Strong problem-solving skills, effective communication, and the ability to mentor junior developers help someone excel in this role. These skills and qualities are crucial for delivering robust, scalable mobile applications and leading successful development teams in a fast-evolving tech landscape.

Senior React Native Engineers often encounter challenges when integrating new features into established codebases, such as ensuring compatibility across different platforms and minimizing disruptions to the current user experience. Managing dependencies, handling legacy code, and coordinating with backend teams to align APIs are also frequent hurdles. Effective communication with product managers and designers is crucial to address edge cases and maintain consistent app behavior. Emphasizing thorough code review and automated testing helps mitigate risks and ensures smooth feature rollouts.

Job description

About FullStack
FullStack is your AI-native engineering partner, built to turn AI capability into certainty. Most companies can demo AI; few can get it to production and prove what it produced. We close that gap with three capabilities, AI built into your products from the start, elite vetted talent who apply it, and transparent execution that shows value every step of the way. With now over 600 customers in North America, FullStack is one integrated partner for all your AI engineering needs. With FullStack, you move forward with confidence.
We're most proud of:
  • Offering life-changing career opportunities to talented software professionals across the Americas.

  • Our client Net Promoter Score of 68, twice the industry average.

The Position
We're looking to hire a Principal Agentic Engineer to join our team. This is a high-impact, client-facing role designed for a "plus-plus" version of a developer, someone who doesn't just build, but defines the architecture of how global enterprises adopt agentic workflows. You will serve as a strategic consultant and technical lead, helping regulated industries and Fortune 500 clients transition from traditional development to AI-augmented engineering productivity.
What We Are Looking For
  • 8-10+ years of professional software development experience with a deep understanding of full-stack architectures (e.g., Java, Python, C#, React, Node, React Native, etc.).
  • Advanced English is required.
  • Successful completion of a four-year college degree is required.
  • Proven experience as a Solution Architect or Principal Engineer, with the ability to assess current engineering states and define roadmaps for implementing agentic solutions.
  • Deep fluency in Agentic Tooling like Claude Code, Cursor, Codex, or GitHub Copilot, specifically within agentic workflows that coordinate implementation across large, multi-file systems.
  • Ability to engage with engineering leadership (CTOs, VPs of Engineering) to defend architectural decisions, consult on industry best practices, and measure ROI/Developer Productivity (Cycle Time, Lead Time).
  • Experience designing development processes where AI systems generate the majority of implementation code, while maintaining rigorous human-in-the-loop validation.
  • Strong skills in structuring codebases and specifications to produce reliable, context-efficient AI output.
  • Exceptional soft skills; ability to walk clients through complex proposals and represent the FullStack team with confidence.
  • Forensic attention to detail.
  • A positive mindset and a can-do attitude.
  • Experience working on Agile / Scrum teams.
  • Meaningful experience working on large, complex systems.
  • Ability to take extreme ownership of your work. Every day is a challenge to ensure you are performing to the expectations you and your team have agreed upon.
  • Ability to identify with the goals of FullStack's clients, and dedicate yourself to delivering on the commitments you and your team make to them.
  • Ability to consistently work 40 hours per week.

What We Offer
  • Competitive Salary.
  • Paid Time Off (vacation, sick leave. parental leave, and holidays).
  • 100% remote work.
  • The ability to work with leading startups and Fortune 500 companies.
  • Health, dental, and vision insurance.
  • 401(k) w/ 4% match.
  • Ample opportunity for career advancement.
  • Continuing education opportunities.

FullStack is proud to be an equal opportunity workplace. We are committed to equal employment opportunity regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, or Veteran status.
