Senior Platform Engineer Job Peru Illinois USA,Software Development

Job Summary

We are looking for a Senior Platform Engineer to contribute to our vision and development of Agentic AI tooling and platforms through technical leadership and proactive thinking. Our product is an orchestration platform that enables developers to spin up isolated, AI‑powered development sessions that autonomously work on tasks – from Jira tickets to Git Hub issues. The team operates without a dedicated product manager;

you will be expected to identify problems worth solving, define requirements, and own features from problem statement to production deployment.

Our technical stack spans Rust for CLI tools and API server, React 19 with Type Script for our frontend, and Kubernetes with Helm on Google Cloud for infrastructure. You will work across this entire stack, leveraging the agentic tooling we build ourselves to contribute effectively beyond your primary domain. Your specialization in systems, infrastructure, and backend development – Rust, Kubernetes, container runtimes, and cloud infrastructure – will make you the team’s anchor for the platform, but you will regularly touch frontend code and UX as the work demands.

The team operates in a startup fashion with a heavy focus on experimentation and prototyping solutions first and evaluating what works in practice rather than heavy upfront requirements given how quickly the agentic space moves.

This is a remote position. We do not offer visa sponsorship or assistance. Resumes and communication must be submitted in English.
