Goodwith is an exciting fintech startup with a mission to develop engaging mobile applications that use cutting edge voice technology and sophisticated real-time algorithms to help you make savvy financial decisions and develop a robust credit score.

Goodwith’s passion is to give all young people access to good financial advice, to help them develop their own financial intelligence, and enable their finances go even further.

Goodwith is at the start of an exciting product journey, and you will play a key role in developing both the products and the business.

The ambition is for the app to become a trusted financial buddy that meets the highest standards for design and experience demanded by modern digitally-native consumers.

This Role

Goodwith is recruiting for a server application and cloud developer who will work at the heart of a dynamic multidisciplinary agile team to develop a platform and infrastructure connecting a voice-enabled intelligent mobile app, financial OpenBanking data sources, state of the art intelligent analytics and real-time recommendation engine.

This is a key role as it will establish and develop the technical architecture for the Goodwith platform supporting current and future products and services.

Python and open source technologies are the overarching strategic choice for server-side applications and components such as proxies and databases.

The role fulfils two key responsibilities:

  • Development of server (backend) applications and databases:
    • The applications will support a mobile app, providing secure user authentication, profile information, user financial data including summary overviews, analytics and recommendations.
    • Core applications will synchronise data from banking and finance sources through the OpenBanking API.
    • Development of secure databases of user and financial data, supporting real-time conversational interactions with mobile app users, and architected to scale with user growth.
    • The applications will also support voice-enabled interaction with a mobile app, providing real-time responses from an analytics and recommendation engine.

Development of scalable cloud hosted infrastructure:

    • Secure cloud hosted environments for the applications.
    • Support for hosted firewalls, proxies, databases, backups, and API interfaces.
    • Monitoring for health, performance, and security.
    • Automated continuous build, test, integration and deployment of applications and data.


You will have 3+ years developing server applications that have been successfully adopted by users, maintained security and performance with growth in users.

Your experience will include working in an agile team, doing iterative development, continuous build, test and deployment systems, and monitoring both infrastructure health and user experience.

Your experience will include working with a security function to design and develop secure applications and infrastructure, assess and mitigate risks, and support formal security assurance processes, ideally in a financial services sector.

You will be able to demonstrate your passion for technology by, for example, contributions to open source projects, personal projects, learning different languages and frameworks, and giving talks and tutorials on server application development and cloud infrastructure.

Team Skills & Capabilities

This role, working in a motivated, dynamic, diverse and ambition team, requires excellent people and communication skills.

You will be able to work at pace to ensure the team delivers to its roadmap and clients.

You are motivated to develop secure, performance, scalable and modular applications that can scale on demand taking advantage of modern infrastructure components provided by Amazon AWS or Google Cloud Platform.

Both technology and business needs can change fast, and you will thrive on the chance to adapt and develop both your technology, and also your own skills, in new directions.
