• Build features end to end — API design, business logic, and integrations between the Ketryx platform and external systems and workflows. Contribute to improving latency, throughput, and fault tolerance across the backend stack.
• Design and evolve PostgreSQL schemas, write efficient queries, and apply indexing strategies to keep the database performant as the product grows.
• Write clean, well-tested code and contribute to standards around migrations, documentation, and testing.
• Participate in monitoring, debugging, and incident response. Help identify performance bottlenecks and reliability issues, and contribute fixes.
• Take features across the finish line in our React/Next.js frontend — you won't own the design system, but you should be comfortable building the UI for the backend work you ship.
• Engage directly with customers, collect feedback, and shape product features with designers, product managers, and the Boston team (Pre-Sales, Sales, Post-Sales, Marketing). Provide technical support to customers alongside Client Operations.

Required

• The ideal candidate is someone who possesses a deep passion for software and a profound desire to contribute to enhancing patient treatments through technological innovation.

• Ability to work in a fast-moving startup environment, taking ownership of features and pushing them forward
• 3+ years of full-time industry experience building production web applications, with a focus on backend development
• Solid skills in TypeScript
• Experience with PostgreSQL or a comparable relational database: schema design, writing efficient queries, and basic performance tuning
• Working knowledge of React, enough to build and modify UI for the features you own
• Solid understanding of backend maintainability, including refactoring and managing technical debt
• Comfortable collaborating across teams in English and participating in technical discussions and design review.
