Position Overview

We are seeking an innovative and driven Senior Golang Engineer to join our high-performing technology team in London. In this role, you will play a pivotal role in executing our enterprise modernization strategy—transitioning legacy, monolithic systems into a nimble, loosely coupled, event-driven microservices architecture.

You will design and build high-throughput, resilient software applications that power key customer engagement, cardmember loyalty, and payment connection platforms. Working closely with cross-functional engineering, SRE, QA, and product teams, you will translate complex business needs into modern system architectures and production-grade code.

Key Responsibilities

• Architecture Transformation: Architect and execute solutions that migrate monolithic systems into loosely coupled, event-driven microservices utilizing Golang, Kafka, and RESTful APIs.

• Resilience & Performance Tuning: Assess and validate application performance, test software resilience and automation tools, and author detailed process flow diagrams.
• Platform Innovation: Build and test Proof of Concepts (PoCs) for modern platforms designed to enhance customer engagement and cardmember acquisition/retention.
• Cross-Functional Collaboration: Partner directly with testing, quality engineering, SRE, and release management teams to ensure smooth transitions through all phases of the Agile development lifecycle.
• Mentorship & Fresh Perspectives: Bring innovative ideas to the team, challenge traditional paradigms, and foster a culture of technical curiosity, experimentation, and continuous improvement.

Minimum Qualifications & Required Skills

• Education & Experience: Bachelor's degree in Computer Science, Engineering, or a related field, accompanied by4+ years of hands-on experience within a modern development stack (Golang, Apache Kafka, REST APIs).
• Distributed Systems & APIs: Deep expertise in designing and building high-volume RESTful APIs and event-driven microservices.
• Database Proficiency: Hands-on experience with relational and NoSQL databases (e.g., PostgreSQL, Couchbase, Cassandra).
• Containerization & Orchestration: Direct experience with Docker and Kubernetes for microservice deployment and management.
• CI/CD & DevOps Tools: Solid knowledge of continuous integration and delivery tools (Jenkins, GitLab CI) and automated build/testing frameworks.
• Agile Ecosystem: Proficiency with Atlassian collaboration tools (Jira, Confluence) within an Agile delivery framework.
• Core Competencies: Strong quantitative, analytical, and problem-solving skills with a willingness to experiment and take calculated technical risks.

Preferred Qualifications

• Payments Industry Expertise: Domain knowledge of payment processing, cardmember loyalty platforms, or fintech transaction flows.
• Open Source Contributions: Track record of maintaining or contributing to open-source frameworks and technical projects.
• Polyglot Background: Exposure to a broad range of distributed software languages and modern payment technologies.
