About Ketryx:
Ketryx is an AI software platform that enables healthcare life sciences companies to ship life-saving regulated products in weeks instead of years.
Exploding product complexity is burying companies in compliance paperwork and blocking innovation. Our AI software removes this friction, dissolving the historical tradeoff between innovation and compliance, and enables regulated industries to innovate at the pace of modern software.
Since launch, Ketryx already touches the lives of 100M patients and powers all of the world's top five medical device manufacturers. Backed by Lightspeed Ventures, our founders are the former Head of AI at Amgen and CTO of Wolfram Cloud.
Healthcare and life sciences is just the beginning for us. Automotive, aerospace, energy — if it's regulated, it's because society decided it matters. These products move humanity, shape our future, and are safety-critical. Come join us and help build the AI platform to power safe innovation.

Responsibilities:
- Backend Development
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. - Database Work
Design and evolve PostgreSQL schemas, write efficient queries, and apply indexing strategies to keep the database performant as the product grows. - Maintainable Systems
Write clean, well-tested code and contribute to standards around migrations, documentation, and testing. - Operational Reliability
Participate in monitoring, debugging, and incident response. Help identify performance bottlenecks and reliability issues, and contribute fixes. - Frontend When Needed
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. - Collaboration
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 Skills:
- 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.
Preferred Skills:
- Experience with Prisma and Next.js
- Experience with GraphQL (urql or Apollo)
- Familiarity with AWS services like S3, RDS, and ECS
- Familiarity with Docker in production or near-production environments
- Strong testing habits (Vitest, Playwright, Cucumber)
- Prior experience with logging and observability tools such as Datadog, AWS CloudWatch, or Sentry
- Experience building AI-related features, particularly for large language models
- Experience working in regulated industries like healthcare or finance.
