Description

Lumosity is a world-leading brain training program with over 100 million users and almost 6 billion games played. Our mission is to help people improve and understand their mental abilities. Lumosity is bringing modern mindfulness practices to our large audience. 
We’re integrating the best of traditional teachings, modern science, and engaging design to create compelling experiences that inspire real practice and learning.
 
We are looking for an experienced Platform Engineer who has helped build and scale service backends before, and feels fairly comfortable with Ruby/Rails tooling to do so. The Core Services team operates as a horizontal team supporting all of Lumos Labs’ apps, so you’ll be working alongside other Platform Engineers, Data Engineers, and Infrastructure engineers to ensure users across all platforms have a great experience. There’s also plenty of opportunity to cross-train with other disciplines on the team, something we value and encourage.

YOU WANT

    • To work on a high-impact team of experienced engineers, writing software that allow users to become their best selves
    • To design backend systems from requirements-gathering with product engineering teams all the way through scaling to millions of users
    • A work environment that encourages collaboration, creativity, and teamwork

YOU WILL

    • Help build the future of Lumosity and its apps by breaking down a monolithic Rails app into constituent services, influenced by microservice patterns
    • Have the opportunity to cross-train with engineers focusing on data and infrastructure systems. In fact, collaborating with these teams is a necessity from day one
    • Not only be working on greenfield projects. We’re extremely proud of many parts of our architecture, as well as many parts that are simply currently locked up in larger systems where they no longer make sense
    • Design, build, and maintain performant, reusable, scalable, and reliable code
    • Think about and recommend long term platform changes to ensure scalability
    • Proactively identify areas for improvement in the software and products
    • Identify and correct performance bottlenecks and fix bugs
    • Contribute to efforts to maintain code quality
    • Break down work into manageable pieces and recommend ways to parallelize the implementation effort
    • Offer input into team process discussions
    • Proactively help teammates when needed

YOU HAVE

    • Significant experience developing and/or maintaining a Rails application at Internet scale
    • The ability to build complex features because you’ve been doing it for quite a while
    • Thorough knowledge of four of the following: Ruby, Rails, Go, React, Redis, Memcached, Nginx, MySQL
    • A mindset where you feel that we can only accomplish our goals together
    • Comfort around developing software that needs to run on many different browsers and mobile devices

WE OFFER

    • A collaborative culture where growth from within is encouraged
    • Regular creative learning sessions, skill shares, forums, guest speakers, and workshops
    • Continuous learning budget for conferences, professional and skill development
    • Competitive benefits (options for individual and/or family medical, dental and vision plans, commuter benefits, parental leave, One Medical membership and much more!)
    • Flexible time off
    • Gym and cell phone reimbursement
    • Catered lunch 4 times a week, fully stocked kitchen & snacks, and dinner when you work late
    • Fun social events such as board game nights, work anniversary celebration, weekly happy hours, and quarterly company-wide events
    • Team lunches and off-sites (past excursions include creative retreats, cooking classes, escape rooms, and terrarium building)
    • We recognize family is important, we host a Bring Your Child to Work Day as well as other kid-friendly offsite events
    • We empower employees to give back to our community and our CSR team hosts volunteer events year-round
