Job description

WHO WE ARE

Choreograph is WPP’s global data products and technology company. We’re on a mission to transform marketing by building the fastest, most connected data platform that bridges marketing strategy to scaled activation.

We work with agencies and clients to transform the value of data by bringing together technology, data and analytics capabilities. We deliver this through the Open Media Studio, an AI-enabled media and data platform for the next era of advertising.

We’re endlessly curious. Our team of thinkers, builders, creators and problem solvers are over 1,000 strong, across 20 markets around the world.

WHO WE ARE LOOKING FOR

Choreograph is looking for an experienced developer to join the team responsible for development of the ecosystem of (primarily) Python microservices. You will be leading a cross-functional team and cooperating with other teams developing services contributing to several products.

Your understanding of the underlying principles of microservices architectures means you will be comfortable operating autonomously, solving problems described in high level functional terms rather than prescriptive implementational detail. You are conscious of the risks to the integrity of API contracts that arise when API implementers and API users breach separation of concerns by collaborating too closely.

You will be responsible for a team of senior developers. You will lead them in definition of processes they follow. You will work with them on the architecture and implementation of systems you will build together.

You will also take part in definition of higher-level architecture of systems you will be interacting with.

WHAT YOU WILL DO

• Lead a cross-functional team of developers
• Lead the development of architecture of systems you build and maintain
• Cooperate with the Product leaders to develop and execute roadmaps for services and products under your care
• Build and deploy back-end services communicating over a range of APIs with other services.
• Write clean, well-designed, and reusable code.
• Test your code on an appropriate level and cooperate with the Developers in Test in creation of testing frameworks
• Acknowledge and be able to explain the tradeoffs with any technical decision.
• Take part in specification workshops where we define functional and non-functional characteristics of our systems
• Demonstrate a solid understanding of separation of concerns, APIs as contracts, and the importance of preventing implementation details and side effects from crossing the API boundary.

WHAT YOU WILL NEED

• Extensive experience on software development.
• Track of leadership of small or large development teams
• Familiarity with Python 3, which will be the primary development language you use in this role.
• Familiarity with agile patterns of development.
• SQL / Database knowledge is essential, you might have used ORMs in the past and you know why you want to avoid them
• Experience working with and integrating complex external REST APIs.
• Experience working with one or more of the leading cloud platforms (GCP, AWS, Azure)
• Experience with serverless architectures (Lambda, Fargate, Cloud Run, et al.) and a clear understanding of when not to use them.
• Experience with message queues (SQS, PubSub, RabbitMQ etc.) and data pipelines (Kafka, Beam, Kinesis, etc.)
• You are an effective team player with effective communication, presentation and influencing skills.
• You have a passion for improving coding and development practices.
• You have worked with microservices communicating over a range of interfaces.
• You understand how the web works, REST APIs, OpenAPI spec/Swagger, GraphQL, and the difference between REST and RPCs.
• You understand TDD, BDD, unit testing, integration testing and when to use them.
• You are familiar with trunk-based development in git.
• Experience with back-end web application frameworks (Django, FastAPI, etc.)

NICE TO HAVE

• Google Cloud (Cloud Functions, AppEngine, PubSub, Stackdriver, etc.)
• Docker, Kubernetes
• Typescript, NodeJS, React, Webpack etc.
• Java, C#
• Experience within the advertising / media agency space.
• Terraform

If you are ready to be at the forefront of the AdTech industry, shaping its future, and driving success for both Choreograph and our clients, we encourage you to apply and join our team.
