Senior Platform Engineer: Storage

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 an infrastructure engineer working on stoarge, you will be directly responsible for designing software and hardware to back performant, high reliability block storage and object storage systems backing millions of applications. The solutions you build will be instrumental in not only scaling internal operations, but scaling the company to infinity 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 (Parts 1, 2, 3, and 4).

For this role, you will:

• Design and evolve multiple production Ceph clusters, from hardware design, to driving network requirements to configuring, tuning and operating clusters and their clients

• Create efficient, generalizable APIs using systems/kernel features to provide safe, as-fast-as-possible live-migrations of stateful workload between hosts

• Design and build API and Orchestration services to tie storage primitives to higher level primitives using Go, gRPC, ScyllaDB and Temporal

• Write Engineering Requirement Documents to take something from idea, to defined tasks, to implementation, to monitoring it’s success

• Design build a suite of storage primitives that can be used by customer applications, internal services and enable higher level platform features such as streaming image pulls or movable build caches

• Experience architecting and implementing distributed systems. You enjoy building fault tolerant, resilient, and scalable services

• Production experience with distributed block device systems (e.g Ceph) or a solid understanding of network storage cluster design from first principles

• Understanding and experience with current gen filesystems (Ext4, ZFS, BTRFS). Bonus points for next gen (EROFS, bcachefs)

• A solid intuition about how long your solutions will last. All systems age. In startups, we can hope for 2-3 orders of magnitude, or 12-18mo.

• The tact to implement your solution, creator monitors for it’s error boundaries, and document any requirements for when you’re not around

• A great sense of direction and prioritization when it comes to dealing with the ambiguity of an early stage startup

• A sense of grit to dive into a problem, implement a solution, scale that solution, and replace it when needed

• A great set of communication skills for getting your point across, solution implemented, and beyond

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.
