 What we’re looking for: 

You're a hands-on Sr. Back-End Software Engineer ready to join the DCOE’s Engineering team. Your primary responsibilities include application architecture design and development of the DCOE’s microservice-based platform.

  • Implement microservices using both asynchronous messaging services and RESTful APIs

  • Conduct innovative technology research, concept specification and design of individual software components 


Who we think would be a great fit:  

We are looking for someone who not only loves designing and building great software but is also passionate about getting stuff done. You are excited by the challenge that comes with delivering innovative solutions for a beloved company and brand going through a digital transformation. You have the skills and experience, but you still love to learn - and you want to work with super talented folks to build great products.

  • You design solutions to integrated systems; you often think in Service-oriented architecture (SOA), microservices, and REST APIs

  • You think that having intelligent data modeling conversations with a data architect sounds like fun  

  • You enjoy refactoring code to reduce code complexity but understand delivery matters more than perfect code 

  • You think in multi-threaded or multi-processor solutions 

  • You know design patterns like the back of your hand and you chose which ones to use based on the task at hand, not just because one is popular at the moment  

  • You are comfortable with performance tuning applications with tools like JMeter or Apache Bench   

  • You prioritize mitigating security vulnerabilities as a part of your normal development process  

  • You are not afraid of Data Oriented Design, in fact, kind of like it   

  • You enjoy heads down coding, but also have great communication skills, love collaborating and are fun to work with   that will be filled at the level based on the skills and experience of the selected candidate.
