Senior TypeScript Engineer

WunderGraphMiami, United Stateslast year

We’re looking for a seasoned Senior TypeScript Engineer whose passion is crafting state-of-the-art, well-tested libraries. In this position, you’ll design, build, and maintain core TypeScript packages, ranging from client SDKs to GraphQL Federation utility libraries, driven by robust algorithms and rock-solid test suites. You’ll collaborate closely with our open-source community, internal product teams, and customer engineering squads to ensure our libraries are performant, extensible, and a joy to use.

You Will Be In Charge Of

Library Development

Architect and implement reusable TypeScript modules (npm packages) for:
Advanced GraphQL federation utilities and clients
Graph algorithms (e.g., traversal, pathfinding, caching strategies)
Performance-critical data structures and helpers

Testing & Quality

Define, execute, and maintain comprehensive unit, integration, and property-based tests
Set up CI pipelines that enforce quality gates, code coverage, and linting

Performance & DX

Optimize algorithms for low latency and minimal bundle size
Continuously refine API ergonomics and developer experience (DX)

Collaboration & Support

Partner with our product and customer teams to gather feedback and iterate swiftly
Diagnose edge-case bugs in production and propose long-term fixes
Engage with the open-source community: triage issues, review contributions, mentor fellow maintainers

Who You Are

Curious Problem Solver & Tinkerer

You thrive on tackling complex challenges, especially around graph algorithms in a federated GraphQL environment, and you’re eager to deepen your expertise by experimenting, benchmarking, and iterating.

TypeScript Virtuoso

You wield advanced TS types, generics, and build tooling with confidence, and you love exploring new language features to make APIs both powerful and ergonomic.

Quality-Obsessed

“Well-tested” means more than high coverage: you craft tests that catch real-world edge cases, and you take pride in a CI setup that enforces quality gates every time.

User-Centric Communicator

You start every project by talking to end users (internal or external) to validate assumptions, refine requirements, and ensure your library designs genuinely solve their needs.

Autonomous & Driven

You own your roadmap end-to-end: scoping work, estimating accurately, and shipping small, valuable increments that delight customers.

Team Player

You work seamlessly across time zones, willingly jump on sync calls when urgency demands, and mentor peers through thoughtful code reviews and documentation.

What You Bring to the Team

3+ years of professional experience building and maintaining TypeScript libraries/packages
Strong proficiency in TypeScript, React, and Node.js
Familiarity with GraphQL ecosystems, federation, code generation, or client libraries
Experience with modern testing frameworks (Jest, Vitest, or similar) and CI/CD pipelines
Solid grasp of npm package workflows, semantic versioning, and monorepo tooling
Huge interest in graph algorithms and willingness to learn and apply graph-theoretic techniques in context of GraphQL Federation
Open-source contributions or personal projects that showcase your library-building skills (GitHub links appreciated)
Excellent communication skills in English for clear technical writing and cross-team collaboration
Willingness to travel twice a year for offsites and major team meet-ups

What Success Looks Like

Customers love our product because it works flawlessly, securely and fast - and because it looks darn pretty, too!
Developers love our product because of the exceptional DX (as said before, we’re an engineering company, so we care a lot about DX)
Your teammates love to work with you because you never let them down, share your knowledge, and ship like crazy as a team
Proper tests and clean code that prevent outages and security issues
You grow along with us
