Hiring Organization Codeable
Company Website https://www.codeable.io/
Remote Locations Worldwide
Job Type Remote, Full-Time

We are looking for a performance-minded back-end engineer with an eye towards writing well-designed, maintainable code who will be responsible for managing and maintaining our back-end system(s) and operating related services connected to it and make sure they (become and) stay performant.

Your primary focus will be the development of server-side logic, ensuring high performance and responsiveness of our back-end system and related services, like our databases (PostgreSQL, Redis), background jobs system (Sidekiq), and other services (internal and external)

Since our backend system is not very new, there are a lot of opportunities to make it better and scalable so we can speed up the growth of our business worry-free. If you are someone who is not afraid to grab a system by its cables and get your hands dirty then you’re at the right place.

Job Responsibilities

Collaborating within our product team to develop new features, fix bugs, and reduce technical debt (you will be involved in the whole application lifecycle)
Defining and communicating technical requirements
Building high-quality systems that can be (re)used and extended in the future
Helping set the design/architectural guidelines to make sure our codebase is improving
Making sure our back-end is scalable (fast response times, optimized DB queries, …)
Troubleshooting, debugging, and fixing production issues

Job Requirements

5+ years of experience with Ruby and Rails in production on a decently sized project
Experience building & growing web applications, APIs, services
In-depth experience of back-end APIs (RESTful web services)
In-depth experience of writing tests: unit, integration, …
Very good understanding of databases: query performance, indexes, migrations (PostgreSQL)
Experience working with background processing (Sidekiq) and how to optimize it for good performance
Ability and desire to produce modular, maintainable code
Solid understanding and experience of Git (branching workflows, managing conflicts, …)
Solid understanding and experience with web (API) security
Experience implementing caching on Rails APIs
Experience working with WebSockets (we use Pusher, but that’s not a requirement)
Strong interest in continued (personal and professional) development (learning new technologies and programming languages)
Good communication skills (English) and willingness to improve. We value quality over quantity
Comfortable working in a remote distributed environment with a high degree of personal autonomy and responsibility

Bonus points

Front-end development knowledge and experience (JavaScript, CSS, HTML, Angular)
Familiarity with Google Cloud services
Experience with using Docker
Experience with using and deploying to Kubernetes
WordPress experience is a plus (since that’s the ecosystem we operate within as a business)
