• Build secure, user centred authentication and access control.
• Design, implement, and document APIs that underpin learning content, reporting tools, and customer support modules.
• Take shared ownership of deployments, monitoring, performance, and platform stability.
• Maintain high engineering standards through testing, peer reviews, and clear documentation.
• Work closely with the wider business to deliver features grounded in real user needs.
• Contribute to improving engineering practices, sprint discipline, and internal knowledge sharing.
• Play an active role in a small, high ownership team focused on long term product scalability.

• Understanding of API development and integration across full stack applications.
• Familiarity with GitHub workflows and Agile delivery using tools such as Jira or Linear.

• Experience working with Drizzle ORM for schema definition, queries, and migrations.
• Understanding of accessibility standards for public facing digital products.
• Understanding of design systems or component libraries to support consistent UI development.
• Exposure to sustainability, carbon accounting, environmental data, or educational technology.
• Exposure to SaaS product development and an understanding of subscription-based feature delivery.

Expected Outcomes

• Delivery of reliable, secure and user-friendly features aligned with product roadmap.
• Code quality maintained through adherence to standards and peer reviews.
• Timely resolution of bugs and technical issues, reducing downtime and improving user experience.
• Active contribution to process improvements and technical documentation.
