At Jet, we’re passionate about empowering people to live and work brilliant. 

    The Environment

    Our platform is largely an event driven platform implemented via a microservice architecture. The platform runs on Microsoft Azure and uses a large number of technologies and middle ware. The bulk of backend code is written in a functional style (F#) and our system of record is an event sourced system (essentially a log of all actions on the platform). We use a mix of Kafka, Redis, Elastic Search, Azure SQL, Event Store and Azure Storage for our data stores. About 50% of the platform runs on Linux and the rest Windows (although we move into more containerization we will see a shift towards Linux).

    The Job

    Our Internal Tools and Productivity Team is looking for a Backend Software Engineer. Our Productivity team here focuses on tools that make engineering as a whole more efficient in their work. Our team is interesting, in that we get to work with every engineering team here – but along with that comes understanding how  our (very large) system works as a whole. Backend Engineers on the Productivity team also aim to help developers write better code that is more resilient and flexible, by actually injecting failures into our infrastructure to make sure that their code handles those failures provide by actively preparing our systems for availability during failure. We are looking for someone that can help determine powerful decisions out of system information, which will include: performance characteristics, service-level agreements between microservices, uptime monitoring, static analysis of a system, and how that system is changing over-time.

    How You Will Have An Impact

    • Every engineer in the company will be using your code to understand how their systems work and what makes them “tick”
    • Teams will rely on the data you produce make educated and impactful decisions
    • Determine functionality that will have the biggest productivity impact on the site.
    • Help prep for “game” days by injecting purposeful failure into environments (Chaos Engineering)
    • Negotiate priorities and roadmaps across various engineering teams
    • Provide best practices to engineering teams in regards to coding standards, and performance/integration testing

    What You Will Learn

    • How an event-based microservices architecture works.
    • You will be challenged by the nature of what needs to occur and the scale involved as well as communicate this nature to teams throughout Jet. Success in this position will give you a great opportunity to be a leader in the space.
    • F# and an even deeper knowledge of distributed systems.
    • Go Programming language (golang) used by many of our internal tools
    • Chaos and performance engineering.
    • You will work closely with incredibly talented people across the company, from a huge variety of backgrounds, (from Technologists to Scientists to Marketers to Consultants and on and on), and learn from their collective experience and through working with them.

    About You

    • Solid programming skills with Object Oriented Programming; experience or interest in functional programming.
    • An understanding of complex distributed systems.
    • Working knowledge of continuous integration/continuous deployment.
    • Azure or AWS experience.
    • Kafka, Redis, Elastic Search, SQL, Event Store and Azure Storage experience.
    • A passion for improving the state of Software Engineering.
    • Not being afraid to poke holes in systems and ask “why?”.
    • BS in Computer Science, Software Engineering or related fields with 5 years of relevant experience.

     Nice to Have

    • Chaos/failure injection experience.
    • Containerization experience.
    • Data Analytics/Machine Learning experience.
