AI-Augmented Lead Engineer (Flutter or React Native + Backend)

Next Era Solutions is looking for Senior / Lead Engineers who can deliver a mobile product end to end with practical, hands-on use of AI coding tools.

This is a fully remote, project-based contractor opportunity. You will own the mobile app, a backend and a simple admin web panel, supported by a shared designer, QA and project manager, with CTO review.

What you will do

• Build and release iOS and Android apps using Flutter or React Native.
• Develop the backend: APIs, database, authentication, push notifications and third-party integrations.
• Build a simple admin web panel when the project requires it.
• Use AI coding tools throughout development, testing, debugging and documentation, while taking responsibility for architecture, security and every line of code you ship.
• Break the agreed scope into milestones with the CTO and demonstrate working software every two weeks.
• Write automated tests, maintain CI checks and prepare releases for the App Store and Google Play.

What we need

• Senior / Lead-level expertise in Flutter OR React Native, combined with hands-on production backend development.
• Experience shipping apps to BOTH the App Store and Google Play.
• Practical experience building and running a production backend and an admin web panel.
• Confident, regular use of AI coding tools, with real project examples you can explain: what AI produced, what you changed, and how you verified the result.
• Automated testing experience: unit tests, widget / UI tests, end-to-end tests and backend API tests.
• Ability to work independently, estimate and plan delivery, communicate risks early and meet agreed dates.
• English at B1–B2 level or higher, sufficient for technical calls and written project communication.

Nice to have

• Native iOS / Android or Kotlin Multiplatform experience.
• CI/CD, store release automation, monitoring and crash analytics.
• Experience with payments, offline features and complex integrations.

Engagement and payment

• Fully remote, project-based cooperation.
• A negotiated fixed budget for each project milestone, paid when the milestone is accepted. This is not an hourly or monthly salary.
• Milestones typically cover 2–6 weeks. Scope, delivery date, acceptance criteria and payment are agreed before work starts.
• Acceptance includes working features, passing automated tests, CTO code review, QA checks on real devices and up-to-date documentation.
• We are building a vetted contractor pool. Project assignments depend on client demand and your availability.

How we select engineers

A short screening call (about 20 minutes), followed by a technical interview with the CTO (about 60 minutes). The CTO interview is the only required technical assessment at this stage; a trial task is not currently required.

Please apply with your CV, links to released apps, your backend stack, the AI tools you use and one concrete example of AI-assisted delivery. Include your availability, monthly capacity and expectations for project / milestone-based payment.
