Senior Site Reliability Engineer (Spain)

About Parser

At Parser, our vision is to become every customer's favourite way to shop, whether they are at home or out on the move. Our core purpose is 'Serving our customers, communities and planet a little better every day'. This means more than a transactional relationship with our customers; it means acting as a responsible and sustainable business for all stakeholders, for the communities we are part of and for the planet.

The Quote team is a core team within the Parser transactional APIs, enabling baskets to be priced for all purchases at Parser, both online and through our tills. Our Engineering Enablement sub-team is at the forefront of this transformation, building the foundational tools and practices that empower our engineering squads to deliver value faster and more reliably. We operate on Microsoft Azure, leveraging a modern stack that includes Java, Kafka, and Couchbase.

The Opportunity

We are seeking a highly skilled and passionate Senior Site Reliability Engineer to join our Engineering Enablement team. This is a critical role within a large, complex, and high-impact initiative focused on deconstructing our monolithic architecture, revitalising our technology stack, and embedding quality and resilience into every stage of our development lifecycle.

You will play a pivotal role in shaping our future-state platform, driving operational excellence, and fostering a culture of continuous improvement.

Why Join Parser?

This isn't just another SRE role; it's an opportunity to be a true architect of change within one of the UK's leading retailers. You will be solving challenging distributed systems problems, and significantly contribute to our strategic objective of accelerating product development and drastically reducing incidents.

We are proud to have an inclusive culture at Parser where everyone truly feels able to be themselves. We not only celebrate diversity, but recognise the value and opportunity it brings. We're committed to creating a workplace where differences are valued, and make sure that all colleagues are given the same opportunities. We're proud to have been accredited Disability Confident Leader and are committed to providing a fully inclusive and accessible recruitment process.

What You'll Do

As a Senior SRE Engineer in our Engineering Enablement team, you will:

• Architect and Implement Reliability: Design, build, and maintain highly scalable, resilient, and performant systems on Azure, focusing on our Java, Kafka, and Couchbase stack.
• Drive Modernisation: Work hands-on as part of the team spearheading the adoption of Micronaut, standardising application templates, and transitioning to managed cloud services.
• Enhance Operational Excellence: Develop and implement strategies for improving system observability (standardised logging, metrics, tracing), alerting, and on-call practices.
• Automate Everything: Champion automation across the software development lifecycle (SDLC), from CI/CD pipelines to infrastructure provisioning, focusing on accelerating delivery and de-risking deployments.
• Incident Management & Learning: Contribute to our mature, blameless post-incident review process, identifying root causes and implementing preventative measures to reduce incident hours.
• Tooling & Standards: Develop, maintain, and drive the adoption of shared, standardised SRE tooling and best practices across engineering teams, including containerisation (e.g., Docker, Kubernetes on Azure), infrastructure as code (e.g., Terraform), and configuration management.
• Mentorship & Collaboration: Provide technical leadership and mentorship to junior engineers, fostering a culture of SRE principles and operational excellence across the wider engineering organisation.
• Strategic Input: Contribute to the overall technical strategy and roadmap for our SRE and platform initiatives, ensuring alignment with business objectives.

What You'll Bring

Essential Requirements:

• Deep SRE Expertise: Proven experience as a Senior Site Reliability Engineer or a similar role, with a strong understanding of SRE principles (error budgets, SLOs/SLIs, toil reduction).
• Azure Cloud Proficiency: Extensive hands-on experience designing, deploying, and operating highly available and scalable applications on Microsoft Azure.
• Azure Kubernetes Service (AKS) Expertise: Mandatory extensive hands-on experience with AKS for container orchestration, including deployment, scaling, monitoring, and troubleshooting.
• Java Ecosystem Mastery: Expert-level proficiency with Java, including experience with modern frameworks (ideally Micronaut, Spring Boot, or similar) and JVM performance tuning.
• Distributed Systems Knowledge: Solid understanding and practical experience with distributed systems, microservices architecture, and associated challenges (e.g., consistency, fault tolerance).
• Messaging & Database Expertise: Hands-on experience with an event streaming platform (ideally Kafka) and NoSQL data storage (ideally Couchbase), including operational best practices.
• Automation First Mindset: Strong scripting skills (e.g., Python, Bash) and experience with Infrastructure as Code tools (e.g., Terraform, ARM templates) and CI/CD pipelines (e.g., Azure DevOps, Jenkins).
• Observability Tools: Experience with monitoring, logging, and alerting tools (e.g., Azure Monitor, Prometheus, Grafana, ELK Stack, Splunk).
• Problem-Solving Acumen: Exceptional analytical and troubleshooting skills, with a methodical approach to diagnosing and resolving complex production issues.
• Communication & Collaboration: Excellent communication skills, with the ability to articulate complex technical concepts to diverse audiences and collaborate effectively with cross-functional teams.
• Continuous Improvement: A proactive and innovative mindset, always seeking ways to improve systems, processes, and team efficiency.
