Senior React Native AI-First Engineer (PK)

Lead-level mobile ownership. AI-first delivery. Architecture decisions.

We are looking for a highly senior mobile engineer who can operate at Lead Engineer level.

This is not a role for someone who only executes tickets. We need someone who can make architecture decisions independently, design mobile systems with long-term scalability in mind, and turn ambiguous product needs into production-ready applications.

This is a high-ownership role on a lean team. The default mode of execution is AI-first. Engineers use AI agents to accelerate research, planning, implementation, testing, and refinement, but ownership stays fully with the engineer. The person in this role must be able to use AI to move fast while maintaining strong judgment around architecture, correctness, performance, usability, maintainability, and overall product quality.

The work

• Design and own mobile application architecture in React Native, from core foundations to production

• Make architecture decisions independently, with a focus on scalability, maintainability, performance, and reliability

• Build and maintain backend services in Node.js that support mobile product functionality

• Design and work with SQL databases, especially Postgres, with strong attention to data modeling, performance, and maintainability

• Define scalable engineering patterns across mobile, backend, and API integration layers

• Own application quality standards across architecture, code structure, testing, responsiveness, and developer experience

• Define technical direction, not just implementation details

• Set and enforce quality standards across both AI-generated and manually written code

• Translate ambiguous product needs into clear technical solutions

• Ensure the performance, quality, and responsiveness of applications

• Collaborate directly with clients to ensure smooth communication and strong understanding of requirements

• Contribute to system design, performance strategy, testing strategy, and engineering productivity

• Operate in an AI-first workflow without compromising engineering standards

This is a fast-paced environment with real production stakes. You will be expected to move quickly, think at systems level, and make strong technical decisions with minimal hand-holding. If you are comfortable owning mobile architecture, contributing across backend systems, and raising the technical bar in a high-accountability environment, this role is for you.

Candidate requirements

• Strong proficiency in React Native, Node.js , and SQL databases, especially Postgres

• Proven experience designing, developing, and maintaining production applications

• Strong understanding of performance, responsiveness, maintainability, and overall software quality

• Ability to communicate clearly with clients and stakeholders

• Full-time availability in a remote environment

• Bachelor's degree in Computer Science or a related field, or equivalent practical experience

• Minimum of 5 years of hands-on development experience

• Exceptional English communication skills, both written and verbal

• Ability to pass a background check with good references
