WunderGraph is a fast-growing startup, our goal is to bring everybody together to build digital products end-to-end. From interface design to API implementation, we provide the platform to go from sketch to product in a category-defining collaborative experience. Our North Star is to take the friction out of bringing digital ideas to life, making room for your ideas and productivity.
Developers from some of the biggest companies in the world are using WunderGraph to design and streamline their API environments. We raised our Series A ($7.5 million USD) in March 2025, being backed by eBay, Karma Ventures, and Aspenwood Ventures.
The culture we are creating together is extremely important to us. Read here how we are Building the Company We Always Wanted to Work In.
We invite everyone that wants to join us to understand our Core Beliefs and 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 so we can chat.
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.
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!
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.
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
Work from wherever you thrive—we’re fully remote and globally distributed. If you're in Miami, come work with us in person! We also provide co-working space options worldwide if needed.

We respect your time and interest in WunderGraph. This is why we're aiming to make the process as fast as possible. Here's what you can expect:
30 min intro call with Alex from our People team
45 min technical background call with one of our engineers. Following this, you might receive a small take home assignment / programming task (max 1 - 2h effort) related to our open source platform. This is your chance to prove your skill!
Complete the assignment and review together with our engineers
Meet the founders
Culture fit call with team members
Offer
Our process also includes reference and background checks. We aim to respond or provide feedback in 2 or 3 days between each stage of the process. We're usually hiring through Deel as our Employer of Record, except for Germany or Florida where we're hiring directly.
