This is a remote position available anywhere in the world! Linkedin makes us show a country, but we hire the best people wherever they are.
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!
For this role, you will:
Build system-level software: our challenges aren't your usual kube-fits-all variety, so be prepared to build things from scratch based on first principles
Have a strong understanding or curiosity of OS level primitives - our business hinges on efficiency, so that means being masters of CPU, Memory, Network and the Kernel that wields it
Be a student of both distributed systems and simplicity - you know how to reach for the RAFT but you also know how far you can get with Postgres
Roll with the boring: build Golang/Rust GRPC services from scratch to expose your complex capabilities to the wider company in a scalable and performant manner
This is a high impact, high agency role with direct effect on company culture, trajectory, and outcome
You may be oncall from time to time in this role
A strong understanding of distributed systems. You enjoy building fault tolerant, resilient, and scalable services
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.
How we hire
No tricks. No surprises. Here's the entire process:
Talk with us about the role
This is completely open ended and we're just trying to see who you are, what you want to do, and where you wanna go.
Work on a small project to discuss in the interview
Asynchronously implement the following:
Pre-interview: Architect a Container Provisioning Engine to power something like Railway
You can, and SHOULD! ask us questions ahead of time.
Review your solution with the Team
You'll sit down with someone on the team and go over the above. We'll poke into your solution, as well as get you acquainted with two more members of the team.
Looking for: Learn about your problem solving skills. How you break down a problem and how you present a solution.
Interview Structure (60 Minutes):
Prework (submitted before your interview): Complete your solution
0-5m: introduction
5-50m: Building (or expanding) your solution
50-60m: Questions on Railway/Tech/etc
Meet the Team
You'll meet the Team, which will be comprised of 4 people from vastly different sections of the company.
Looking for: How you work with the rest of the team and communicate.
Offer and Details Chat with CEO
Finally, we will go over the process, the role, and hammer out the details about your position, onboarding, and all the deets.

Know your rights as a candidate and an employee:
The job is in San Francisco, CA. Below is what the official statistics say about living and working there.
How San Francisco compares. Among the 145 largest places in California, San Francisco is #4 by population, #139 for homeownership (#1 = highest), #20 for remote work (#1 = most), #25 for college degrees (#1 = most). Its county, San Francisco County, is #3 of 58 counties for average pay ($174,103).
San Francisco has 830,235 residents (ACS 2020–2024), about 2.1% of the population of California. It covers 47 square miles of land, which works out to roughly 17,784 people per square mile. The median age is 40.0, 6% older than the state median (40.0 against 37.9).
The median gross rent is $2,476 a month (rent plus utilities), 22% above the state median ($2,476 against $2,036). Over a year that is 21.1% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $1,394,500, which is 9.9 times the median household income ($140,970); a ratio above 5 usually means buying is out of reach without savings or a second income. 38.2% of households own their home, 32% below the state average (38.2% against 55.9%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.
The San Francisco-Oakland-Fremont, CA metropolitan area has 2,373,920 jobs in the BLS wage survey, and the median pay across all occupations is $74,260 a year, 46% above the national median ($74,260 against $50,980). The biggest occupation groups are office and administrative support (226,320 jobs, median $62,120); management (223,100 jobs, median $176,340); business and financial operations (207,030 jobs, median $112,960). The area is most specialised in computer and mathematical (1.9 times) and life, physical, and social science (1.8 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($176,340) and computer and mathematical ($167,770). In 2026M09 the unemployment rate of San Francisco County was 4.0%. 69.6% of residents aged 16 and over are in the labour force. The city lies in San Francisco County; its jobs, pay by industry and GDP are on the county page.
Among workers, 28.6% drive alone, 18.7% use public transit, 9.3% walk, 31.0% work from home. 21.6% of workers commute 45 minutes or more, 11% above the state average (21.6% against 19.4%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.
60.3% of adults aged 25 and over hold a bachelor's degree or higher, 63% above the state share (60.3% against 37.1%). 34.0% of residents were born outside the United States, 26% above the state share (34.0% against 27.0%). The poverty rate is 11.2%, 7% below the state rate (11.2% against 12.0%).
The warmest month is Sep, averaging 59°F (14.9°C), and the coolest is Apr at 53°F (11.6°C). About 515 mm (20 inches) of precipitation falls in a year; Dec is the wettest month (112 mm) and Jul the driest (2 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.
Closest cities in this guide: Daly City (31 miles, rent 3% higher); Pacifica (31 miles, rent 25% higher); San Bruno (34 miles, rent 12% higher); Millbrae (36 miles, rent 32% higher). Rent differences are against San Francisco; use the Compare tab to put any two cities side by side.
