Job description
WunderGraph is a fast-growing startup, and we’re on a mission to redefine how companies leverage GraphQL Federation at scale. Our North Star is to enable collaboration across small and large organizations by using APIs as the backbone of business growth. If you want to make an impact, have your voice heard, and work in a no-BS organization where you can get stuff done—look no further and apply today! 🚀

About the Role

We're building WunderGraph Cosmo, the open-source GraphQL Federation solution. Probably the most important component of Cosmo is the Cosmo Router, which - simply put - connects all API endpoints and handles the GraphQL requests and responses whilst applying the Federation protocol (among other magical things, like normalization, execution planning etc.). Fully written in Go, it's the fastest GraphQL Router available and a quite potent (and complex) piece of cutting-edge open-source software. How about joining our team to make it even better and strap the rocket boosters onto GraphQL Federation?

TEAM INTEGRATION

You report to the CTO.

You align with the CEO (product) and the CCO (customer feedback)

You support and consult with the engineering team.

You will be in charge of

Develop, refactor and maintain GraphQL Go Tools' (Router) open-source code base in Golang (low GC code)

Work closely with your engineering team mates on new Router capabilities (e.g. Open Federation, new data sources)

Focus on performance, security and stability of the Router

Review Router telemetry to identify areas of improvement

Run internal penetration tests of the Router

Troubleshoot Router issues, potentially together with our customers' engineers

Analyze and accept up open-source contributions on Github

The "Engine" is essentially a Golang application which translates GraphQL requests into any other protocol, like OpenAPI, SOAP, gRPC, GraphQL, Apollo Federation, etc... You could consider the Engine as a "GraphQL Compiler" or Transpiler. The Engine is responsible for parsing, normalization, execution planning, execution runtime, etc... If you are interested in working with ASTs, AST transformations, etc... you will love this kind of work. We have performance requirements, so you should be proficient in writing performant and low GC code in Golang.

Some of your tasks will take more than a few weeks to complete, Ideally, you're someone who likes to go deep on one topic instead of going wide and shallow on many different topics.

Here's a list of things you might be working on:

Extend the Compiler "backend" to support Apollo Federation v2

Extend the Compiler "backend" to support gRPC

Implement a native Go-based data source for SOAP and OpenAPI, currently we're using a Node.js based solution with a bridge

Improve the batching-implementation of the Engine

Improve the performance of the Engine in general, driven by feedback from our customers

If I (the CEO) had more time, I'd do all of this on my own, just because I enjoy this kind of work. Unfortunately, my role requires me to focus on Marketing, Sales, Product, and other aspects of the company. That's why we're looking to expand our "Engine Team" with you!

What you bring to the team

Senior level of proven Golang development experience in a leading / ownership role (must have)

Self-starter with a clear sense of priorities - no hand-holding needed

You must be willing and able to work out solutions on your own. This requires you to dig into hard problems and stay on target until you have solved an issue in a robust way.

Experience in working with ASTs, AST transformations etc.

Experience in writing performant and low GC code in Golang, and knowledge of how to benchmark Go code

Experience with GraphQL, API Gateways, Proxies, and Networking in general is a plus

Experience with OpenAPI, SOAP, gRPC, GraphQL, Apollo Federation is a plus

Open-source contributions are a benefit, too

You are able to work and thrive in a fully remote environment

Excellent communicator (important for a remote team) in English

You are willing and able to travel occasionally to meet the team in person (at least twice a year) or join working meetings.

You are able to work within the CET time zone.

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
