Job description

Overview

Senior Backend Engineer to join the Space and Range team at Holland & Barrett. In this role, you will help develop and enhance tools that shape how our stores are designed—from the overall layout to the placement of bays and shelves. These tools visualize store environments in 3D to provide teams with a near real-life view of the customer experience in-store. You’ll work on impactful, business-critical products that influence how we present and optimize our key sales channels, contributing to growth strategy and customer experience.

We’re looking for someone who thrives in a culture of ownership. If you believe in a “you build it, you own it” approach and take pride in building robust, high-quality systems, you’ll fit right in.

You’ll be part of a supportive, cross-functional team serving an international business. Our hybrid working model offers flexibility to work remotely most of the time, with occasional in-person sessions for planning, collaboration, and team building at our offices in London or Nuneaton.

Key Responsibilities

• Design, implement, and maintain scalable backend services using Java and Spring.
• Work with databases, including SQL (e.g., Postgres) and NoSQL (e.g., DynamoDB).
• Build, test, and optimize technical solutions.
• Develop event-driven systems leveraging Kafka for messaging.
• Collaborate with cross-functional teams, including frontend engineers, UX, and product management.
• Contribute to architectural decisions, ensuring maintainability, scalability, and high performance.
• Take ownership of production systems, ensuring they run smoothly and meet user expectations.
• Build tooling for debugging, monitoring, and support automation.

Qualifications

• Proven experience in backend development with Java.
• Proficiency with Spring Boot and Hibernate frameworks.
• Experience in building APIs, microservices, and implementing event-driven architectures.
• Experience with databases, including SQL and NoSQL.
• Familiarity with AWS cloud services such as S3, RDS, and DynamoDB.
• Strong focus on writing clean, modular, testable code with experience in unit and integration testing.
• Hands-on experience with CI/CD pipelines and version control systems like Git.

Benefits and Perks

• Pension company contribution = 3%
• Incentive scheme up to 10% of annual salary, based on company performance.
• 33 days holiday per year.
• Private Medical Care (Self after 1 year)
• Learning and Development opportunities for long-term career development.
• Career progression.
• Refer and Earn Scheme.
• Epic Extras with access to exclusive benefits, discounts, and savings.
• 25% discount on products from day one.
• Free 24/7 confidential advice & colleague welfare.
• Mental Health First Aiders and health-focused wellbeing initiatives.
• Onsite gym at the Nuneaton hub.
• Colleague reward and recognition schemes.
• Many more benefits.

We’re passionate about helping every colleague thrive across all dimensions of wellbeing and are committed to a diverse and inclusive workplace.
