Eulerity
Associate Web Development Software Engineer (SDK)
About this role
Eulerity seeks an Associate Web Development Software Engineer to design and ship developer-facing SDKs while building AI-powered automation workflows.

What you'll do
- Design, build, and ship developer-facing SDKs consumed by other engineers, owning the public API surface, TypeScript types, and semantic versioning
- Develop and maintain AI-powered automation workflows connecting the product to internal and external systems
- Build and test new features using AI-assisted tooling, maintain the codebase, integrate with APIs, and own the full PR lifecycle
- Ensure SDK backwards compatibility, documentation quality, and packaging/distribution across bundlers and npm
- Collaborate with web, mobile, and backend teams on architecture and best practices
- Partner with Product and Design to translate requirements into shipped solutions
What they're looking for
- SDK and library design with strong API surface and developer experience focus
- React and TypeScript (2–3 years professional experience)
- AI workflow automation (LLM API integrations, agentic tooling)
- Library bundling and distribution (tsup, Rollup, Vite, npm publishing)
- HTML, CSS, JavaScript fundamentals and REST API integration
- Code review, PR workflows, and agile practices
- Technical writing and documentation
- Separation of concerns and framework-agnostic architecture design
Benefits
- Comprehensive medical, dental, and vision coverage
- Unlimited PTO and Summer Fridays
- 401(k) with company match
- In-office lunch stipend and unlimited snacks
- Commuter benefits
- Hybrid work model (3 days in NYC office per week)
