Backend Engineer

Ketryx is an AI software platform helping healthcare and life sciences companies develop safe, compliant medical products. The Backend Engineer will build backend features, APIs, integrations, database systems, and reliability improvements while contributing to frontend work, customer collaboration, and product development.

Responsibilities

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
