How to Apply for Senior Software Engineer — Node, TypeScript, Frontend Ecosystem

at Sourcemap

🏢 About Sourcemap

Sourcemap is revolutionizing supply chain transparency to combat deforestation, forced labor, and unfair wages. As a mission-driven startup serving global brands in food, fashion, and electronics, you'll work on software that directly impacts ethical sourcing and sustainability.

About This Role

As a Senior Software Engineer, you'll architect scalable systems using Node, TypeScript, Angular, and Next.js, shaping patterns for clarity and maintainability. Your work will directly influence the platform's evolution, enabling resilience and supporting the company's growth.

💡 A Day in the Life

Your day might start with a standup discussing architectural decisions with the CTO, followed by coding a new feature in TypeScript/Node. After lunch, you'd review a peer's PR focusing on system boundaries, then pair with a frontend dev to optimize an Angular component. Afternoons often involve asynchronous collaboration on resilience patterns.
