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.

MANUAL is a digital personal development and mental wellness platform designed to inspire young men to become the best versions of themselves. Today, male students are far less likely to be enrolled, retained, and graduate from higher education institutions, and this is especially true for young men of color. Their mental health outcomes are rapidly worsening, with young men dying by suicide and overdose at alarming rates.

MANUAL works with high schools, universities, and fraternities across the country - including the University of Mississippi, Morgan State University, and MSU-Denver - to solve this challenge, bringing high-quality men's success and mental health programming to tens of thousands of students. MANUAL has raised capital from Expanse Venture Partners, 12-48, the Inner Foundation, and angel investors from companies like Maven Clinic, McKinsey & Company, Eleanor Health, and more. MANUAL's evidence-based approach has been proven to enroll young men who are not currently being reached by existing services, and users report significant levels of trust towards the service.

Are you passionate about crafting efficient and scalable applications? Do you want to use your skills to help thousands of young men around the country? If you're enthusiastic about full stack Typescript, and love the thrill of a startup, we'd love to talk to you!

Who We're Looking For:

Typescript Enthusiasts: You have a solid understanding of Typescript and the JS ecosystem. You've built or contributed to web applications and APIs using these technologies and are excited about crafting beautiful, efficient, and scalable web applications. You've written production frontend and backend code.

Problem Solvers: Complex challenges excite you, and you excel at finding innovative solutions. You understand that in a startup environment, delivering a functional solution that meets users' needs is more critical than crafting a perfect solution that never launches.

Team Players: Our small but growing team values collaboration and open communication. Your input will significantly impact our projects, and we value engineers who are humble and willing to assist their peers.

Lifelong Learners: Your willingness to learn and grow is vital. We appreciate those open to new ideas and experiences, understanding that everyone has something to teach.

What You Won't Need:

• A specific number of years of experience. Your ability to apply what you've learned to new challenges is what truly matters to us. We're not in a position to provide the support and mentorship a very junior developer needs (ex. fresh out of college or dev bootcamp), so you should have experience shipping production code.
• A formal education in computer science. We recognize the value of diverse educational backgrounds and learning paths. Our head of engineering, for example, doesn't have a computer science degree.

What You'll Do:

• Contribute to the development of our RedwoodJS-based web application, potentially setting the direction for this greenfield project.
• Assist in the management of our Postgres database and backend infrastructure.
• Contribute to our React Native and NextJS apps
• Engage in user feedback sessions to directly learn from our users and adapt our solutions to better meet their needs.
• Be involved in the hiring process for future engineering team members, helping us grow our team with talented individuals.
• Play a pivotal role in defining our engineering processes and culture.
• Collaborate closely with our head of engineering and other team members on a variety of backend and frontend projects, contributing your unique skills and perspectives.

Important Details

• Job Type: Full-time, remote work environment with occasional optional travel for team get-togethers.
• Compensation structure: We are considering engineers with a range of experience and skill for this role, and will make cash offers of $115k-$140k per year. A competitive equity plan will be provided.
• Benefits: Fully covered (no employee contribution) Health, Dental, and Vision insurance. Unlimited PTO.

• 30 minute intro call with Karl Morand, our head of engineering. This call will be focused on getting to know you, your background, experience, and answering any questions you have about MANUAL or the role. We won't get into anything super technical (no live coding or anything like that). A list of some topics/questions will be provided to you before the interview - the goal is to see you at your best, not test your ability to remember anecdotes from your past under pressure.
• Take home project is the next step. You will have at least 5 days to complete the project. The goal of the project isn't to nitpick your code, but rather to give us a starting point to discuss how you approach solving problems with code.
• 45 minute technical call with Karl Morand, our head of engineering. In this call we'll use your take home project as the basis of our discussion on how you approach solving problems. All candidates who complete the take home project will advance to this stage. This call will include a more detailed discussion of your technical experience and knowledge.
