Apply Now:

• We make enterprise web applications for record labels (music industry)
• Looking for full-stack Ruby engineers (Rails-like or Python/Django + want to learn Ruby)
• Would like 2 or more years of professional web development experience
• Positions are full time, fully remote and/or we have an office in Los Angeles
• Starting salary 100-150k (depending on experience) + benefits

• Participating in a weekly planning meeting where we review our goals and prioritize work to be done for the coming week.
• Participating in daily engineering-only meetings (roughly 30min) where the team collaborates on technical decisions, resolving issues, and reducing complexity.
• Writing tests: we write mostly full-stack integration tests and use a single testing framework for all parts of the code.
• Writing application code: mostly Ruby, some HTML, some Javascript. CSS is mostly handled by visual design.
• Reviewing code: We do round-robin code reviews as a means of knowledge sharing. All pull requests are reviewed by another engineer. You’ll take turns reviewing everyone else’s code and they will take turns reviewing yours.
• Deploying code: We deploy small changes to production code multiple times per day. Deployments are automated with lots of fail-safes and we rely on third party services for devops as much as possible.
• Maintaining code: Maintenance is a part of all code changes but we also plan specifically for improving code quality and updating to newer conventions, techniques, and technologies. You will also be reproducing and fixing the occasional bug.

• Estimating work to be done. Instead we try to break work down into small enough chunks that they can be done quickly.
• Reporting progress. Work is done when it’s deployed. Instead we try to reduce the scope of work that is growing complex.
• Stakeholder meetings. While agile processes are all about open channels of communication we find too much can be overwhelming. We have technical product managers who work with stakeholders instead, allowing everyone else to focus on their work while getting their questions answered.

• Relational database concepts such as: foreign keys, indexes, normalization and denormalization, SQL queries.
• Writing Ruby code in an MVC web framework. We don’t use Rails but we follow many of the same conventions. We’ve had success bringing people on from Python/Django so if you have Python experience and would like to learn Ruby it might be a good fit.
• Some familiarity with Javascript. We push as much behavior as possible to the server but features often do have small client-side components.
• Writing tests. We practice integration-test-heavy outside-in test-driven development. If you’ve practiced any sort of test-driven development you will pick it up fast.

• OpenPlay Music is a monolithic application backed by a PostgreSQL relational database. Heavy operations are processed asynchronously by scalable background workers that notify clients via WebSockets. At present we have plenty of room to scale.
• Our server-side code is MVC-structured and built on Sequel (ORM), Sinatra, and HAML. If you’re familiar with Rails (or similar MVC frameworks) you’ll find a lot of similarities and many of the same conventions here.
• On the client side we use StimulusJS to apply bits of dynamic behavior where it improves the user experience, most of which ultimately requests updates from the server.
• There are currently around 2500 full-stack browser-based integration tests covering every feature from user input to expected output. CI runs on every git push and completes in about 15 minutes.
• We do things typical of web applications like:
  • Store data in, and query from, a relational database (PostgreSQL)
  • Index data and query it with filtering and full text searching (Elasticsearch)
  • Handle slow tasks with background processing
  • Push asynchronous updates to clients with WebSockets
  • Export XML files, PDFs, CSVs, Excel spreadsheets, and other formats that just won’t seem to go away
  • Import data from Excel spreadsheets, (music-industry standard) DDEX XML, JSON, and various other sources
  • Communicate with lots of external systems across all manner of bespoke APIs
  • Provide JSON APIs for our customers to build on top of
  • Use git for version control, build features in branches, and take turns reviewing pull requests
  • Run everything on cloud infrastructure
  • Rely on service providers for devops as much as possible (Heroku, etc)

• Starting salary 100-155k depending on experience
• Medical, dental, and vision insurance
• Whatever tools, services, books, etc you need to do your job
• Low stress environment: The industry we’re in is comparatively low scale and high value. While we work with lots of data we avoid some of the technical issues and constant urgency you might find with consumer applications.
• Good work/life balance: We expect that everyone works full time (40 hours/week). We do sometimes have deadlines and we haven’t always limited scope appropriately. The last time we worked late nights was in 2019 for about a week. The time before that was in 2016 for about 3 weeks. Our most recent deadline we met two weeks early.
• Flexible work and vacation schedule. You are free to work the hours that work best for you (outside of our scheduled meetings) and we don’t have a set limit on vacation days.
• Free to work remote. We’ve been doing remote work as long as we’ve been around and our process is built around it. Some of our team is permanently remote, others work out of the office part time.
• Office near the beach in Santa Monica you can use any time.
• Free lunch at nearby restaurants when you’re in the office. Some of which are delicious.

• Prior work experience that looks like it might be a good match for what you’ll be doing at OpenPlay.
• Some understanding of how to program well. Maybe a computer science degree or other academic background. Code contributions you can point to. Blog articles you wrote. A particularly enlightening reddit comment.

Apply Now:

Mission Statement

The additional yield that MEV provides has become a core part of staking returns, and the MEV-Boost architecture operates close to the core of the Ethereum protocol. The Aestus MEV relay was established by members of the Ethereum solo-staker community with one core mission: to improve economic decentralisation on Ethereum.

Aestus has been live on mainnet for 18 months and we are responsible for auctioning ~5% of Ethereum mainnet blocks. We’ve recently attracted community funding that provides us the opportunity to grow our team.

This is a competitive and dynamic environment where milliseconds matter. We are looking for a DevOps engineer whose primary responsibility will be to optimise our architecture with performance in mind. New ecosystem developments such as shared sequencing, and re-staking also present us with new opportunities - which you will have an essential role in exploring.

Summary of the Role

• You’ll be working in a small, friendly 3-4 person team with an opportunity to make your mark.
• Experiment with new technologies and make data-driven improvements to the performance, observability, and stability of our platform.
• Architect, configure and deploy global infrastructure on leading cloud platforms.
• Take responsibility for incidents and become a part of the on-call team.
• Engage in community discussions and contribute to the evolution of this ecosystem.

Qualifications

• A hacker mentality with substantial self-driven experience of linux sys admin, git, docker and k8s.
• Familiarity with common database technologies and networking protocols.
• Fluency in any of golang, python or rust.
• An understanding of the Ethereum staking and MEV ecosystem.
• A willing to get involved in novel technical challenges beyond a strict DevOps remit.

Benefits

• Remuneration dependent on skills and experience.
• Work from anywhere on a contract basis with flexible hours.
• Paid travel + expenses to Ethereum conferences and team meetups.

The role

DevOps is a buzzword, but it’s also generic enough to encompass the breadth of tasks required in supporting development teams. There are many ways to make the lives of developers easier, and everyone has their own best way, which also means every team has their own way. There is no perfect way to make everyone happy with the same thing.

Supporting developers involves debugging obscure bash scripts from years ago that nobody remembers. It means biting on a piece of wood and using data formats turned programming languages like YAML to configure CI jobs. It means tracking down minute differences between releases of packages and libraries causing unexpected crashes. It means rewriting the same Dockerfile for the 5th time to allow a project to use one more obscure library. Or tracking down absurd race conditions of multi-threaded tests running in parallel on the same host. Or pulling your hair out at a bug only to realize it works fine after the CI worker host is restarted.

But fundamentally it means wrestling it all into submission and making it run smoothly… at least for as long as you’re there.

If you have the guts to fight against entropy and deterioration of the reality we inhabit, then you just might also be crazy enough to enjoy the struggle while it lasts, and appreciate the eventual fruits of our labour, if you value privacy, freedom, and transparency. You might even make some money, and learn a bit from all the exceptional engineers working here.

Who you are

You have strong Linux Fundamentals:

• Distros and package managers
• Good understanding of process management

You have programming experience:

• At least a few languages and showing the ability to learn
• Bash as a minimum; Python would be helpful

You have experience in Continuous Integration:

• Jenkins CI - Pipelines are written in Groovy
• GitHub Actions - PR builds, mostly

You have experience in Security:

• Good understanding of OpenSSH
• GnuPG for encryption of secrets and backups

Distributed Systems:

• Experience running Ethereum nodes
• Knowledge of Layer 2 scaling solutions

Compensation

We are happy to pay in any mix of fiat/crypto.
