Klaviyo is a data science company that helps brands grow faster. We're profitable, engineering-driven and growing incredibly fast. We have over 12,000 paying customers and are doubling year over year and ingesting an order of magnitude more data every year.
We're hiring across the board (Python/Java engineers, systems engineers, site reliability engineers, hands-on team leads, security engineers, data scientists, product managers, designers, and more). We run a DevOps culture and love full stack engineers who code code in both Python and Javascript (we use React and TypeScript).
Our tech stack is predominantly Python (Django), Java and JS/React running on AWS at massive scale. We run thousands of EC2 boxes, 100s of Aurora MySQL and PostgreSQL clusters and petabyte scale Cassandra clusters. We're heavy users of Kafka, RabbitMQ and Redis. We've just recently launched our first workloads on Kubernetes. We send billions of emails every month and fire customers that send spam--our goal is helping customers have more effective long-term relationships with their customers. We also do push notifications, website personalization and soon SMS.
We recently raised one of the largest fund-raising rounds in Boston history ($150m) but don't intend to change our core values which includes growing our business organically.

Acquia is hiring for a variety of DevOps roles - Boston, MA
Acquia Cloud is a platform as a service tuned to run some of the largest websites on the planet. Although we're focused on Drupal (essentially the largest open source project in the world) on the cloud team we utilize a variety of languages and operate a polyglot PaaS engineered for enterprise needs.
We're one of Amazon's largest customers and run over 8000 AWS instances. Do you want to not just do DevOps but instead join a team devoted to DevOps at massive scale? If so let me know!
Acquia, itself, was named the fastest growing private company in America last year.
We have openings for junior and senior DevOps engineers, distributed systems engineers, systems administrators, low-level developers (C modules, Kernel engineers, etc.) and more.
We utilize a variety of languages and technology, including: Ruby, Puppet, MySQL, Cassandra, Python, Go and more!
Let me know if you want to work on exciting DevOps project at ludicrous scale such as:
* Architecting highly scalable and resilient PaaS services using technologies such as Docker
* Developing a monitoring infrastructure in Sensu to monitor 10s of thousands of hosts
* Building next-generation Virtual Private Cloud network security features to power some of the most secure websites on the planet
* Scaling a platform health feature to millions of datapoints using Graphite and Cassandra
Andrew didn't ask, but I thought I'd just add my 2 cents:
I've been at Acquia for a few years and it's a fun place to be.
Running a system on such a large scale is one of the coolest things I've done in my career so far and there is something new and interesting happening every day.
Something that is appealing (at least to me), is that the team is running a very "professional" process.
All of the commits are code reviewed and have passing tests, the colleagues are all great and impressively capable engineers. Everybody is excited about adding things like code metrics, good refactorings and helpful tooling (travis ci, ...). Even though it's a somewhat "streamlined" process, there is still enough time to fix those annoying little things (Upgrading the Ruby version we use, restructure our puppet manifests for logical consistency, ...).
It's a great place to learn and work in a team that actually lives the whole DevOps idea.
Andrew (syrneus) is an Engineer and understands the problems that business requirements can have with the current way we're doing things.
Ok, enough now before the marketing department tries to get me to write a blog post ;)
We run hundreds of GlusterFS clusters in production on EC2. We're currently on 3.0 and in the process of fully migrating to 3.4 (and maybe 3.5 one day).
Our primary use case for Gluster is in serving persistent filesystems for Drupal. Our customers store potentially millions of files on their GlusterFS clusters.
We've built a number of tools/processes to help protect Gluster against failures in EC2 (for instance fencing network traffic at the iptables layer to help protect GlusterFS clients from hanging talking to down nodes), as well as to help our team perform common tasks (resizing clusters, moving customers from cluster to cluster, etc.). We haven't necessarily hit blocker issues recovering from underlying hardware fails, but our team is definitely very experienced with many possible failure modes.
Overall GlusterFS has been very reliable over the years and our research has shown it is the best option out there for when our customers can't use something such as S3 directly.
If you want more details or would love to hack on a 8000+ node EC2 cluster running things such as GlusterFS feel free to ping me.
At 8k+ nodes, bare metal would likely be much cheaper. Why would you possibly want to host this on EC2?!
Disclaimer, I've been at companies with thousands of servers for my past 3 jobs. I've never once used any "cloud" service other than Linode for my personal VPS and ganeti for the Oregon open source lab VM donated to the gnome foundation (I'm a sysadmin alum for gnome.org)
Many of our customers do use S3 and we make use of S3 extensively ourselves. However, Drupal often expects to operate on a POSIX compatible filesystem. Drupal 7 does support PHP file streams which can be configured to use S3, but not every Drupal module follows the best practices. Plus, we support every flavor of Drupal under the sun (including custom code).
All of our enterprise customers receive a highly available setup running on multiple nodes--thus, we have the need for a persistent filesystem attached to multiple EC2 instances. We utilize GlusterFS to ensure all of our clients have the filesystem capabilities their apps may need.
Basically, they need EBS without the single-instance (writable) mount limit, if they're using it to sync Drupal installations (php files, temp folders, etc.) across multiple web servers. S3 isn't really intended for that kind of workload (it would be possible to use something like s3fs, but I don't think that will give you a POSIX-compatible file system which is required for Drupal, and it's probably too slow as well (lots of small files, etc.))

It's really a shame because the only jobs which really interested me in any way required US citizenship and security .
One thing I'm curious about is this: is 2 years of experience really the lowest requirement for a junior developer? [1] It seems like if the applicant had any more, they could hardly be counted as a "junior developer" and would just be "a developer."
