Build and maintain frontend functionality using React and TypeScript, supported by HTML and CSS.
Develop backend services within a Python environment, including Flask, Django, and FastAPI.

Create and modify custom APIs within Microsoft Dynamics 365 Business Central, and develop the services connecting applications to it.
Build and maintain Power BI reports, collaborating with business colleagues to understand reporting requirements and investigate issues.
Work constructively with development partners through delivery and handover, identify maintainability concerns, flag material gaps against agreed business requirements, and maintain documentation for ongoing development and application support.
Contribute to user journeys and interface improvements, with opportunities to present work directly to business stakeholders.
Diagnose defects and integration failures, investigate underlying causes, and implement maintainable fixes.

Requirements
Education: Bachelor's degree or higher in Computer Science, Mathematics, Physics, or Engineering.
Demonstrable experience developing and maintaining live software products, including delivering functionality, resolving operational issues, and taking responsibility for improvements after delivery.
Practical experience building and maintaining React and TypeScript applications, with a sound understanding of HTML and CSS.
Strong backend development experience, including designing, building, and troubleshooting custom APIs and system integrations.
Some practical experience building and maintaining Power BI reports.
Confidence in understanding unfamiliar codebases, tracing problems across connected systems, and learning new technologies.
Sound development practices, including version control, debugging, appropriate testing, and clear documentation.
Initiative, resourcefulness, and accountability: ability to follow problems through, make considered technical decisions, and recognise when to seek support.
Clear communication with technical colleagues, external development partners, and people without a technical background.
Experience in a product company or startup is strongly preferred, particularly where you have contributed directly to product development, maintained live applications, and dealt with the operational consequences of your technical decisions.
Strong backend and API development capability is essential. Previous Python experience is advantageous, but developers with strong experience in other backend languages who can quickly become productive in Python will be considered.
Previous Business Central integration or AL development experience is also advantageous. Willingness and ability to learn the Business Central development environment to build custom APIs and connect it reliably to applications is required.
