About

We’re building Omni: a platform allowing developers to deploy applications across all rollups without fragmenting liquidity. We’re looking for early team members to help us bring this ambitious vision to life.

We’re a team who already built a platform that processed over $70M leading to our $18M fundraise from top investors including Pantera, Two Sigma Ventures, Coinbase Ventures alongside angel investors including Stani Kulechov (founder of Aave), Sandeep Nailwal (cofounder of Polygon) and more.

• Location: Must be in the New York (EST) or Europe (CET) time zones.
• Overlap hours: Available daily from 9 AM to 12 PM EST for team collaboration.

Competencies

• Autonomous — specifically seeks to take greater ownership and responsibility and thrives in their personal growth by doing so
• Action oriented — we are looking for people who take action by default, consistently driving forward progress without asking for permission
• An engineer in both thought and implementation — they must be able to design architecture and see it through to implementation
• Adaptable — thrives in ambiguity, able to quickly iterate and push forward as the business dynamically expands
• Highly intelligent — learns quickly and can participate in abstract intellectually engaging conversations
• Effective communicator — clearly articulates ideas and engages in debates in a productive manner that leads us to making better decisions

Operating principles

• High-trust & autonomy
• Kindness & respect
• Collaboration
• Humility & low-ego
• Transparency
• Data driven
• Precise communication
• Results oriented
• “Kerplunk”: clean handoffs and acknowledgement of ownership between team members

The future belongs to all of us, independent of our origins. Omni is an equal opportunity employer and does not discriminate on the basis of race, religion, color, sexual orientation, gender or any other status protected under federal, state or local law.

• 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.

• Answer support questions related to our WordPress themes and plugins (Sydney Pro, Botiga Pro. and Merchant Pro) via our email ticketing system (HelpScout)
• Create CSS and PHP snippets for customers who request small customisations
• Communicate bugs/improvements with our developers

• You know WordPress inside out
• You are familiar with WooCommerce, and willing to learn more
• Strong HTML, CSS and PHP and preferably some familiarity with Javascript.
• An understanding of browser console errors and debugging via developer tools
• Patient and polite when dealing with support queries
• Good written English (not necessarily native, but clear and professional)

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.

Hiring process

• Interview with the Talent team
• Paid task
• Technical interview with Head of Infra

[The steps may change along the way if we see it makes sense to adapt the interview stages, so please consider the above as a guideline]
