We are looking for a strong Full Stack Engineer who is proficient in both back end and front end development.

The day-to-day activities:

• Design, build, rollout, and operate cutting edge backend services built primarily in Go that service high throughput (thousands of QPS) with low latencies (in the order of a few milliseconds)

• Service capacity and demand planning
• Root cause analysis
• Tuning and optimization
• Incident management
• Work in a cross functional team of SREs, backend engineers, and frontend engineers to design scalable, efficient, and performant engineering platforms
• Design, build, rollout, and operate large scale data processing pipelines
• Participate in code and design reviews with the team, for software run as realtime services (primarily Go based), in event driven architectures (using streaming / queueing), or as batch workloads (e.g. using Spark)
• Collaborate with product and experience teams to define and prototype feature specifications

Requirements

The must haves:

• A degree in Computer Science, Software Engineering, Information Technology or related fields and/or a demonstration of strong computer science fundamentals
• 4+ years of experience in software engineering in a distributed systems environment. Some experience in Frontend.
• Familiarity with running large scale web services; understanding system internals and networking are a plus
• Strong understanding of system performance and scaling
• Excellent communication, sharp analytical abilities, and the ability to think critically of the current system in terms of growth and stability
• You can be a good coder in any language (Go, C++, C, Java, Scala, Rust, Haskell, OCaml, Erlang, Python, Ruby, PHP, Node.JS, C# etc.), but willing to work on our tech stack

Tech Stack

The Customer Data Platform team uses Go for backend services, Kafka as an event log, Spark as a batch processing stack, ScyllaDB, DynamoDB, and RDS MySQL for data persistence, with a Redis for cache and Elasticsearch for full text search for segments. The frontend stack is built with Javascript using React. Our SDLC involves working with Terraform, GitLab, Jenkins, and a range of other internal tools, and operations involve working with AWS, Kibana, Datadog, and potentially Kubernetes.
