Your Role at MediaLab
About the company
MediaLab Engineering supports a number of applications across multiple business verticals which have been acquired through a careful selection process to integrate with its internal Ad platform that processes billions of impressions a month.
Kik, our messaging brand carrying more than 4 billion messages a year, is looking for a savvy, experienced Backend Engineer to join their talented team. As a backend engineer at Kik, you design, build, and run the Go services behind messaging, groups, safety, and Kik Live, our live-video product, as well as support the move of our remaining legacy Java services to Go. Most of your time focuses on service code; the rest goes to shipping and operating what you build: containers, Kubernetes deploys, CI, and monitoring.
We also believe in working smarter. AI tools are part of how we build, and we expect you to use them to move faster, explore ideas, and remove tedious work. You’ll treat AI-generated code with the same scrutiny you’d give a teammate’s pull request: reviewing it critically, testing it rigorously, and validating that it meets our standards for correctness, security, and maintainability. The tools help you go further. Your judgment and engineering fundamentals are what make the work reliable.
Please Note: This is a contract position, and we are only considering candidates based in Mexico or Argentina. Professional English proficiency is required for this role.
What You’ll Do
•
Build and extend Go micro services, including gRPC APIs and data models
•
Migrate legacy Java services to Go
•
Work AI-first: direct coding agents such as Claude Code to build, test, and migrate services, then review and verify everything they produce before it ships
•
Ship your services with Docker, Kubernetes, Helm, and GitHub Actions
•
Instrument and monitor your services in Datadog
•
Review code, and debug production issues across services
•
Build security and data protection into the services you own
•
On-Call Schedule: Participate in a week-long on-call rotation, typically once every four weeks, depending on team size.
