At Quantcast, we’re redefining what’s possible in digital advertising.

Our foundation is built on cutting‑edge measurement and consumer analytics, giving our clients the tools they need to drive success in an ever‑evolving digital landscape.

Since our start in 2006, we’ve pioneered industry firsts—from launching the original measurement platform for digital publishers to introducing the first AI‑driven DSP. If you’re ready to be part of a dynamic, forward‑thinking team that thrives on creating transformative solutions, Quantcast is the perfect place to grow your career.

Quantcast is hiring a Software Engineer to join the Payments & Incentives Team in our London Office. We are building the next generation advertising platform to enable our customers to run digital advertising campaigns on the open web as simply and effectively as possible.

• Define, code, test, and deploy software focused on process simplification and automation.
• Work directly with internal customers and other business stakeholders to understand requirements and contribute to product definitions and system and solution design.
• Follow the engineering best practices as defined by the team and organization, from testing, deployment, documenting, operating services and code quality.
• Participate in code reviews and provide constructive feedback to team members.
• Participate in a team‑wide on‑call rotation.

Who you are:

• 1‑2 years experience working as a Software Engineer.
• Computer Science degree or equivalent experience (We recognize that knowledge and skills equivalent to those earned in a degree program can also be achieved via nontraditional paths, and welcomes applicants with nontraditional training.).
• Strong core Java skills (knowledge of GO is highly desirable).
• Experience in designing and implementing APIs and Microservices.
• Understanding of the full software development life cycle (scoping, prioritization, planning, execution, operation, end‑of‑life) and the tools that assist it (source control, continuous integration, deployment tools) in an Agile environment.

Bonus points:

• Experience with JavaScript and Front‑End technologies like React, Redux, Redux‑Saga, Hooks, TypeScript, ES6, SASS (and more).
• Experience of Cloud technology (AWS or similar).
• Experience with container technologies (Docker or similar) and container orchestration tools (Kubernetes or similar).
• Understanding of Messaging Technologies (Kafka, SQS).
