# Senior Platform Engineer

- **Company:** CommScope North Carolina, LLC
- **Location:** San Francisco, CA, United States
- **Experience:** Expert
- **Contract:** Permanent contract
- **Skills:** Amazon Web Services, Databases, Python (Programming Language), Terraform
- **Published:** November 7, 2026
- **Apply:** https://www.juju.com/job/28_25303_14c36fb53a7c617b7b3acadb4d7c8c65

## About the Role

* 4+ years building real systems, with Python and AWS as home turf
 * Experience with managed services and Terraform, which we use heavily, and the judgment to know when a managed service stops being the right answer
 * You've operated something under load and know what it feels like when a queue backs up at 2am
 * You can look at a half-built system and decide what to finish, what to fix, what to start next and what to buy time on
 * High agency: on a small Series A team, nobody writes your tickets. You figure out what matters next and take it there
 * Ambitious and kind. As a founding member of the engineering team, you'll shape the architecture and the standards everyone else builds against

## Description

* Build out our distributed execution engine: the workers, queues and orchestration that fan out tens of thousands of simulated conversations a day and bring back scores
 * Own the data side, from the databases holding conversations, audio and judge results to the pipelines that move them between stages
 * Make real cost trade-offs. Every model call and storage byte has a price, and you keep unit economics sane as volume climbs
 * Stand up and maintain the environments where our LoRA training jobs run, as a key part of the plumbing for our ML work
