Job description

We are seeking a highly skilled and motivated Senior Backend Engineer with a strong foundation in Python and object-oriented programming. In this role, you will be responsible for designing, developing, and maintaining the server-side components of our software applications. You will collaborate closely with cross-functional teams—Data Engineers, Cloud Engineers, and Product stakeholders—to deliver scalable, secure, and efficient backend solutions.

The ideal candidate will have solid experience in CI/CD pipelines, cloud infrastructure (especially AWS), and modern backend architectures. Exposure to JavaScript and PHP is desirable, and familiarity with event-driven or microservice-based patterns is a plus.

We are also looking for someone who can bring experience or interest in AI Engineering to build intelligent services and working alongside Data Scientists to deploy scalable AI-driven features and applications. A familiarity with cloud-based AI/ML services in Snowflake Cortex or DOMO AI would be a strong advantage.

About Us:

We are a progressive Customer Acquisition / Direct Response Media Planning and Buying Agency. All Response Media has seen a sustained and successful period of growth both organically and new business wins and is now ranked in the top 15 UK Media Planning and Buying agencies.

Headed by the most senior executive board of any UK-based performance agency, with over 160 talented professionals working from our offices in London, Leeds, Amsterdam and Paris, we collaborate with clients, technology partners and stakeholders to deliver successful solutions to clients of all sizes, operating across all market sectors.

We do the best job possible because we really do care. That means we should be as accountable, responsive and expedient as possible, pragmatic yet innovative and always enthusiastic.

Key Reponsibilities

• Design and implement robust, scalable backend systems using Python as the primary language.
• Apply object-oriented principles and design patterns to maintain clean, maintainable code.
• Leverage cloud-native services (primarily AWS) including Aurora, Load Balancer, Security Groups, and serverless compute options.
• Build and maintain CI/CD pipelines using industry-standard tools (e.g., GitHub Actions, GitLab CI, Jenkins).
• Implement monitoring and logging using tools like DataDog, Serilog, CloudWatch, or equivalent.
• Use Docker and Kubernetes for containerization and orchestration of applications.
• Manage deployments with Helm and configuration in YAML.
• Develop shell scripts and automation for deployment and operational workflows.
• Work with Data Engineering to integrate and manage data workflows using Apache Airflow and DAG-based models.
• Perform comprehensive testing, debugging, and optimization of backend components.

Required Skills

• Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience).
• Proven experience as a Backend Engineer or a similar role, with a strong track record of designing and developing robust backend systems.
• Familiarity with logging frameworks like Serilog for efficient log capturing and analysis.
• Experience with containerization tools like Docker and orchestration frameworks like Kubernetes.
• Knowledge of Helm and YAML for defining deployment configurations and managing releases.
• Proficiency in shell scripting for automating deployment and maintenance tasks.
• Understanding of DAG (Directed Acyclic Graph) models and experience with Apache Airflow for managing complex data processing workflows.
• Familiarity with database systems (SQL and NoSQL) and proficiency in writing efficient queries.
• Solid understanding of software development best practices, including version control (Git), testing, and code review processes.
• Strong problem-solving skills and the ability to work effectively in a collaborative team environment.
• Excellent communication skills and the ability to clearly articulate technical concepts to both technical and non-technical stakeholders.
• Competitive salary and bonus structure
• 25 days annual leave + Bank holidays
• Annual company away day
• Free fruit in the office
• Flexi-Friday where employees can start earlier in order to finish earlier on selected Fridays
