Senior Software Engineer (Java/Spring/SQL/JUnit)

As a Senior Software Engineer with GfK based in London, you will be provided with a great opportunity to work as part of an agile feature team of technologist within the GfK product ecosystem. Specifically, you will work in a squad (mixing other developers, SREs, UI/UX designers, Product Owners, and Product Managers) dedicated to a project for the GfK Client Platform. For this opening you will be part of the Platform Services, the teams that looks after authentication and authorisations (subscriptions) for the whole platform.

You would initially help us in our migration phase from some of our current internal and external services and splitting some of our core applications into Microservices. Therefore, this role would require someone with a more focussed backend experience with Databases and data modelling.

This opening would suit either a Node.js or a Java backend engineer as the project consists of the mix. That said, a good grasp of SQL and data analysis techniques is crucial for this role as you will lead data transformation, schema design and query read/write optimisation efforts.

You will report to the Platform Services Tech Lead and work with your product counterpart, the Principal Product Manager for the Domain alongside the Domain Architect.

• 8 years+ solid programming skills in Java (JDK 8+ and Spring)
• 5 years+ working experience of databases and SQL
• 5 years+ working experience of Microservices and RESTful APIs
• 5 years+ Experience analysing DB query plans (execution plan)
• Experience optimising SQL Read/Write queries
• Knowledge in TDD and unit testing
• Experience with Design Patterns and Object-Oriented design
• Solid computer science/engineering fundamentals, including data structures and algorithms
• Experience with Source-Control systems, CI/CD pipelines and containerisation
• Experience with a Google Cloud Platform (GCP). If you have experience with other cloud providers, you can pick up GCP with us
• An interest in helping other engineers become even better

It would be nice you have:

• Experience with enterprise web-applications
• No-SQL Databases such as MongoDB and Search indexes such as Elasticsearch or Solr
• Experience building Single Page Applications
• Google Cloud or similar could platforms
• Experience of micro-services at scale
• An understanding of Unix systems
• Experience in Agile development like SAFe
• Wear a Scrum Master hat from time to time
• Some awareness of JS tech stack such as Node, React and Typescript

You Will:

• Utilise TDD, that is a test first approach in writing unit and integration tests
• You would analyse Postgres query plans (execution plan)
• You would improve Postgres Read/Write queries performance
• Identify and address application and data issues that affect application integrity.
• Fix any defects and performance problems discovered in testing.
• Suggest projects (e.g. training) that improve working efficiency and quality.
• Work with the architects and an Agile team to influence the system architecture and performance goals.
• Contribute to Agile practices, such as estimating and planning.
• Collaborate well with team members
• Document technical effort from time to time

Our Benefits:

• Exciting work environment that brings people together
• Use the latest digital technologies
• Ongoing trainings to support your development
• Opportunities for personal and professional growth
