[Hiring] Senior Golang Engineer @WunderGraph, Inc.

Role Description

We're building WunderGraph Cosmo, the open-source GraphQL Federation solution. Probably the most important component of Cosmo is the Cosmo Router, which connects all API endpoints and handles the GraphQL requests and responses whilst applying the Federation protocol.

Fully written in Go, it's the fastest GraphQL Router available and a potent 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 align with the Product team and Customer Success teams for product feedback.
• You support and consult with the engineering team.

Your Responsibilities

• Develop, refactor and maintain GraphQL Go Tools' (Router) open-source code base in Golang (low GC code).
• Work closely with your engineering teammates 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 open-source contributions on Github.

The "Engine" is essentially a Golang application which translates GraphQL requests into any other protocol, like OpenAPI, SOAP, gRPC, etc. You could consider the Engine as a "GraphQL Compiler" or Transpiler.

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.

Potential Projects

• 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.
• Improve the batching-implementation of the Engine.
• Improve the performance of the Engine in general, driven by feedback from our customers.

Qualifications

• 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.
• 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.
• Excellent communicator in English (important for a remote team).
• Willing and able to travel occasionally to meet the team in person (at least twice a year).
• Able to work within the CET time zone.

Requirements

• Experience with GraphQL, API Gateways, Proxies, and Networking in general is a plus.
• Experience with OpenAPI, SOAP, gRPC, GraphQL, Apollo Federation is a plus.
• Existing Open Source Contributions.

Benefits

• Work from wherever you thrive—we’re fully remote and globally distributed.
• Pick your preferred work hardware.
• Discretionary PTO: take the time you need to recharge.
• Competitive compensation.
• Healthcare benefits according to local standards.
• Team retreats across the globe.

The Process

• 30 min intro call with Mariya from our People team.
• 45 min technical background call with one of our engineers.
• Complete a small take-home assignment/programming task (max 1 - 2h effort).
• Review the assignment together with our engineers.
• Meet the founders.
• Culture fit call with team members.
• Offer.

WunderGraph is an equal opportunity workplace; we welcome people from all backgrounds. We’re looking forward to your application so we can grow together!
