// SYS.ONLINE — 2501.AI COMMAND INTERFACE

2501 builds autonomous AI agents that operate directly in the shell to complete real production tasks - not just synthetic evals. We treat LLMs as pluggable brains, mixing open‑source and flagship models to get the best result. By fusing their output with observability data we surface root causes fast and automate the dull parts of incident response for corporate engineering teams who can’t afford downtime.

We’re a tight‑knit team of Dev Ops, Platform, and Infra engineers who ship fast, learn constantly, and elevate each other every day.

Why 2501 ?

We use AI to solve real problems in the underlying layers of every IT stack. We build what is the future of IT, ensuring every brick of our clients’ infrastructure is up and running.

We discovered an amazing opportunity to make IT more reliable and modern and we’re building the best way to make it a reality. Our customers and investors and backing this with strong commitment and foresee in our mission the future of IT.

We’re backed by three leading European VC funds, giving us the resources to aim high and take risks.

What you’ll do
  • Own features end-to-end across our Type Script CLI, Postgres data layer, evals, and deployments.
  • Build the tooling that makes our autonomous agents reliable in real production environments.
  • Work with multiple LLMs – open‑source and flagship – and squeeze the best result out of each.
  • Ship fast, measure with evals, and iterate directly with customers.
Who you are
  • You’ve shipped complex production systems and owned them in the wild.
  • You have an AI‑native workflow and treat agents as part of how you build.
  • Owner mindset – you see something broken and you fix it.
Not for you if
  • You’d rather stay comfortable in a narrow lane.
  • You only want async work with no real-time collaboration.
Why you’ll enjoy working here
  • Fully remote – work from anywhere in the EU; we have a soft preference for the Paris region or somewhere easily reachable, and keep core hours in CET for smooth collaboration.
  • Competitive pay & meaningful equity – you own a piece of what you build.
  • Small team, big impact – your work ships to users the same day.
Our stack
  • Frontend – Vue + Nuxt.
