Senior Software Engineer (Architect/Principal) - React Native

At Continia, we’re building the mobile finance experience that our 10K+ business customers have been waiting for. Continia One is our new unified, lightning-fast, and genuinely delightful app that brings all our products together for 100K+ business users globally - all inside one native-feeling experience.

Phase one is all about invoice and payment approval workflows, and expense management such as submitting expenses, mileage, and per diems. Phase two is already taking shape in our labs, and it’s part of a bigger plan to launch a new product that’s going to change key processes and how most businesses work with them.

We’re looking for one truly exceptional mobile engineer—someone who can operate at senior, architect, or principal level. You will take ownership of key architectural areas, deliver robust and scalable solutions, and ship world-class code to shape the technical future of Continia One.

About the Role

You’ll join a small, high-impact team that’s building Continia One from the ground up. No legacy code, no bureaucracy, just the freedom to make something outstanding.

You’ll work across the full stack of the app: core platform, shared architecture, reusable components, and the product modules themselves. One week you’re defining the long-term module system, the next you’re optimizing a critical feature that 100.000 users use every day.

You’ll work closely with product, design, and backend teams, make big technical calls, set the engineering bar, and ship polished, truly native experiences on iOS and Android.

Key Responsibilities

• Drive architectural and technical direction for Continia One, built with React Native and TypeScript.

• Build core features, shared modules, and reusable components supporting multiple product domains.

• Ensure top-tier performance, scalability, and maintainability through modern patterns and tooling.

• Contribute to the mobile design system and ensure a consistent, accessible user experience across all modules.

• Collaborate across teams to review code, share insights, and improve engineering practices.

• Provide guidance and mentorship where your expertise adds real leverage.

• Maintain strong build, release, and testing processes, including automation, OTA updates, and app store deployment.

• Support broader engineering initiatives such as CI/CD improvements, telemetry, observability, and cross-platform consistency.

What We’re Looking For

• Proven experience building and maintaining production mobile apps.

• Deep expertise in React Native, TypeScript, and mobile architecture.

• Strong understanding of performance, platform differences, and mobile build pipelines.

• Pragmatic problem-solver with strong collaboration and communication skills.

• Passion for technical craftsmanship and mentoring others.
