Job Description

Business Unit:

Metadata Senior Software Engineer

The CoMPASS (Comcast Metadata Products and Search Services) team is building a world-class API platform for delivering metadata content to X1 TV set-top boxes, mobile apps, recommendation engines, and other clients. Our platform is designed to handle hundreds of millions of requests supporting millions of customers a day. In order to provide a smooth and rich experience for our customers, we focus on four primary attributes during our design and development:

  • Scalability-our code is written to scale horizontally on nodes in multiple data centers to handle the large request volume.
  • Performance-request responsiveness is paramount, which requires us to find solutions to persist data in memory when possible and work with various caching solutions.
  • Response Consistency-it is important that we minimize inconsistency across nodes and data centers, which requires us to develop solutions to reduce propagation times across our cluster.
  • Resiliency-our services need to be able to continue serving requests even when there are dependent service outages or network partitions.

The Position: Senior Software Engineer

The software engineer on our team is involved in many phases of the development cycle: design, implementation, testing, performance analysis, and deployment. We are looking for someone who enjoys collaborating with others to find new and innovative solutions to solve problems.

Core Responsibilities:

  • Work with open-ended product descriptions and translate them into great code.
  • Write production-quality, well tested code.
  • Develop solutions that scale in order to support request volumes that reach into the hundreds of millions a day.
  • Write performant code where milliseconds matter; analyze the performance of services, identify non-performant code, and provide solutions to problem areas.
  • Participate in research, design, and recommendations for new solutions and technologies.
  • Find better ways to monitor our services to identify and alert on potential problems using tools such as Grafana and Splunk.
  • Mentor more junior members of the technical staff, performing code reviews, and lead the team to be effective and agile.

Required qualifications:

  • Superior knowledge of Object Oriented design and patterns
  • Proficiency with Java
  • Exceptional communication skills: verbal, written, listening

Highly Desirable:

  • Familiarity with in-memory database such as Hazelcast, Redis, Memcached
  • Experience working with and developing in AWS
  • Familiarity with messaging solutions such as Kafka, SNS/SQS, RabbitMQ
