We're building a team of talented engineers who enjoy solving complex technical challenges, thinking creatively and developing high-performance software that makes a real difference.

The Role

We're looking for an experienced Senior Software Engineer to architect and develop core frontend and mobile systems for our fintech platform.

This is a hands-on technical role where you'll take ownership of designing and building robust, scalable and secure software components, with a strong focus on performance, reliability and cross-platform compatibility.

You'll bring deep expertise in native Android and iOS development, alongside strong knowledge of C/C++, software architecture, multithreading and cryptographic operations. You'll work across macOS and Android environments, developing high-performance systems and reusable libraries that support our core platform.

Beyond development, you'll contribute to architectural decisions, establish engineering best practices, review code and mentor junior developers. You'll also work closely with product managers and other stakeholders to translate technical requirements into reliable software solutions.

We're looking for someone who combines strong engineering fundamentals with a practical, problem-solving mindset and an interest in using modern AI tools and LLMs to improve the way software is developed.

Where You'll Make an Impact

In this role, you'll:

• Own software architecture and design. Design and architect core software components and libraries, create technical specifications and system design documents, and ensure solutions are scalable, secure and maintainable.
• Lead development and implementation. Develop high-performance frontend systems and reusable software libraries, with a focus on reliability, efficiency and quality.
• Drive cross-platform development. Build and maintain solutions across Android and macOS environments, ensuring compatibility and consistent performance.
• Implement secure cryptographic operations. Develop and integrate encryption, decryption, hashing, digital signatures and other security mechanisms to protect financial transactions and sensitive information.
• Champion engineering quality. Conduct comprehensive code reviews, maintain coding standards and promote clean, maintainable and well-documented code.
• Improve performance and reliability. Profile applications, identify bottlenecks, optimise memory usage and resolve complex technical issues involving concurrency, multithreading and system performance.
• Build robust testing practices. Implement and maintain automated testing frameworks, including unit and integration testing, and promote test-driven development.
• Ensure security and compliance. Apply appropriate security practices and ensure software meets relevant financial industry security standards.
• Provide technical leadership. Mentor junior developers, share knowledge and provide technical guidance to support the development team's growth.
• Collaborate across teams. Work closely with product managers and other stakeholders to understand technical requirements, evaluate solutions and deliver against product objectives.
• Contribute to engineering best practices. Participate in agile development processes, sprint planning, technical documentation and continuous improvement initiatives.
• Embrace AI-assisted development. Use LLMs and modern AI coding tools, including Claude, Cursor, Gemini and ChatGPT, for prompt engineering, coding, debugging, refactoring and test generation.

Who You Are

You're someone who:

• Thinks like an engineer. You enjoy understanding complex systems, solving difficult technical problems and building solutions that are reliable, scalable and maintainable.
