Remote Senior Software Engineer - Disney+

At Disney Streaming we’re responsible for building what aims to be the largest media streaming platform in the world, serving not just Disney+, but ESPN+, Star+, and Hulu. We foster innovation, we challenge each other, and we put our users before all else: connecting them with the stories they love.

We’re looking for people who want to challenge themselves, to grow; people who understand scale… and care deeply about reliability. You will be surrounded by colleagues eager to help you succeed and be part of an ambitious, high-performing, rewarding culture. If this sounds like something for you, read on!

HOW WE WORK

The teams in Manchester work in small squads that promote Agile practices. Each team and their respective squads are responsible for a collection of microservices and their infrastructure, from building to delivery and maintenance. We take great pride in owning what we build and seeing things through to the end.

We have a mature DevOps culture in place where teams are responsible for the infrastructure and deployment of those applications. We are actively expanding our Manchester born SRE function, which aims to advance our knowledge and innovation globally in areas such as Observability, Reliability and Availability.

We have the autonomy to choose the technologies and processes that help us achieve our objectives. So each team leverages the technology that fits their needs best. You’ll see us working with data processing / streaming like Kinesis, Spark and Flink; application technologies like PostgreSQL, Redis & DynamoDB; and breaking things using in-house chaos principles and tools such as Gatling to drive load… all deployed and hosted on AWS.

Our services teams are advocates of functional programming, so you can expect to join a team that’s applying principles from FP to build these services: using Scala, Cats, ZIO, http4s, FS2, and Cats Effect.

THE TEAMS

Experimentation

Our high-scale in-house A/B testing platform. Deeply integrated into our platform to enable experimentation on every aspect of the product. We’re building a fully bespoke platform using cutting edge technologies, capable of serving millions of concurrent requests with single digit millisecond response times. We provide our users with a fully self service experience including comprehensive in-tool curation and analysis of experiments.

We’re also responsible for our platform’s feature flagging capabilities, extending our experimentation platform to provide fully dynamic, user specific configuration to all clients, enabling a truly universal end to end process for test, rollout, experiment, release, rollback capabilities.

Customer Experience / QoS

Our team builds services to measure the Customer Experience for Video Playback, in real-time. This means taking high throughput streaming event data (~10TB/day) generated by our client applications, and creating a user experience to support our analysts who generate insights into the underlying quality of the streaming experience, driving improvement. It requires us to make technical tradeoffs between what we can achieve with the data we can gather, and the requirements from our internal users on a regular basis.

Token Services

We help to secure the platform using OAuth 2.0 & JWTs. Generating tokens used by our applications every time they make service requests to e.g. discover and playback content, including by third parties such as Google Assistant initiated playback. We also build internal tooling to help our teams test and debug in production.

Being a critical path multi-region service means we set the bar high for availability. We serve billions of requests per week with double digit millisecond response times. Reliability, scalability, and cryptographic agility is critical to us!

Subscription Services

Responsible for supporting new customer signup and retention flows, billing services and payment integrations. The Subscription team supports high traffic API services that provide the source of truth for all products, subscriptions and entitlements owned by our subscriber base. This data is surfaced globally to our streaming client apps as well as via real time data streams that feed other platform services and our analytics capabilities. The team also supports subscription management functionality providing users the ability to upgrade/ downgrade their plan or cancel, for example as well as driving the subscription lifecycle including supporting monthly renewals.
