Senior Infra Engineer - Platform

Job description

Our core mission at Railway is to make software engineers higher leverage. We believe that people should be given powerful tools so that they can spend less time setting up to do, and more time doing.

Building the infrastructure which powers the Railway engine is the most core problem at Railway. As a infrastructure engineer, you will be directly responsible for exposing the knobs, bells, and whistles that allow the users to build to the wildest dreams. The tools you build will be instrumental in not only scaling internal operations, but scaling the company to infinite and beyond!

“But the world would be a better place if more engineers, like me, hated technology. The stuff I design, if I'm successful, nobody will ever notice. Things will just work, and will be self-managing”

- Radia Perlman

Want to learn about our work culture? Here is a three-part blog series that will help you see the unique ways our team works (1 and 2 and 3).

Required Qualifications/Experience

Expect to need all of these, day to day, to excel at Railway

  • Built application level code (Golang, GRPC, Postgres, etc)
  • Made use of OS primitives (syscalls, cgroups, etc)
  • Delivered projects 0→N. Lead it, scaled it, seen your “brilliant solutions” become tech debt, etc
  • Operated with agency and urgency (bonus points if remotely!)
  • Had enough foresight to ship for today, design for 10x, and engineer for 100x in 18mo
  • Communicated clearly using RFCs/Docs/etc to break up + deliver large, nebulous tasks
  • Been oncall and know that you will be 1-2 weeks per quarter
  • Constructed monitoring, alerts, and dashboards to notify you before things break
  • Built the confidence to say no to 99% of things, and the grit to deliver the 1% that matter
  • Desired Qualifications/Experience

    Expect to go deep in 1-2 of these to do the best work of your life

  • Baremetal Networking at 1T+ request/mo scale (eBGP/eBPF, L2-L7, Wireguard)
  • Orchestration at 100m+ containers scale (Runtimes/Hypervisors, Live-migrations, RTOS)
  • Metrics/Logs/Traces at 1T request/mo scale (Vector, VictoriaMetrics, Clickhouse)
  • Block storage, filesystems, replication at Petabyte/drive scale (ZFS, Ceph, VirtioFS)
  • Efficient OCI build/transfer at TBps/sec scale (BuildKit, SOCI, Zot, overlayfs)
  • Building “datacenters” (in quotes because closet server racks and HomeLabs count!)
  • We value and love to work with diverse persons from all backgrounds

    Things to Know

    For better or worse, we're a startup; our team dynamics are different from companies of different sizes and stages.

    • We're distributed ALL across the globe, and that's only going to be more and more distributed. As a result, stuff is ALWAYS happening.
    • We do NOT expect you to work all the time, but you'll have to be diligent about your boundaries because the end of your day may overlap with the start of someone else's.
    • We're a small team, with high ownership, who are not only passionate about what we do, but seek to be exceptional as well. At the time of writing we're 21, serving hundreds of thousands of users. There's a lot of stuff going on, and a lot of ambiguity.
    • We want you to own it. We believe that ownership is a key to growth, and part of that growth is not only being able to make the choices, but owning the success, or failure, that comes with those choices.

    Benefits and perks

    At Railway, we provide best in class benefits. Great salary, full health benefits including dependents, strong equity grants, equipment stipend, and much more. For more details, check back on the main careers page.

    Beyond compensation, there are a few things that we believe that make working at Railway truly unique:

    • Autonomy: We have very few meetings. Just a Monday and a Friday to go over the Company Board. We think your time is sacred, whether it's at work, or outside of work.
    • Ownership: We're a company with a high ownership, high autonomy culture. We hope that you'll come in, help us, and over the course of many years do the best work of your life. When we bring you onboard, we expect you to change the company.
    • Novel problems/solutions: We're a startup that's well funded, with cool problems, which lets us implement novel solutions! We abhor “busywork” and think, whether it's community, engineering, operations, etc there's always opportunity for creative and high leverage solutions.
    • Growth: We want you to grow with us, but we know that talent is loaned, so when you figure out what area you want to grow in next, whether it's at Railway or outside, we'll make sure you land there.
