Full Job Description
đź“‹ Description
- • 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
- • You will be in charge of:
- • Developing, refactoring and maintaining the Router's open-source code base in Golang
- • Working closely with your engineering team mates on new Router capabilities
- • Focusing on performance, security and stability of the Router
- • Reviewing Router telemetry to identify areas of improvement
- • Running internal penetration tests of the Router
- • Troubleshooting Router issues, potentially together with our customers' engineers
- • Analyzing and accepting up open-source contributions on Github
- • You will be working on:
- • The Router, which is the fastest GraphQL Router available and a quite potent (and complex) piece of cutting-edge open-source software
- • The Engine, which is a Golang application that translates GraphQL requests into any other protocol
- • You will be responsible for:
- • Developing, refactoring and maintaining the Router's open-source code base in Golang
- • Working closely with your engineering team mates on new Router capabilities
- • Focusing on performance, security and stability of the Router
