ABOUT FLUTTER FUNCTIONS

The Flutter Functions division provides essential support and services across Flutter Entertainment, spanning finance, legal, human resources, technology, and more — ensuring seamless operations and strategic alignment across the company.

ROLE OVERVIEW

The Strategic Intelligence team transforms complex data into actionable insights that guide technology strategy across Flutter's global portfolio. As a Senior Software Engineer, you'll build the technical backbone of our AI-powered Strategic Intelligence platform — connecting data sources, user interfaces, and automated workflows to drive strategic decision-making. Working closely with our AI Analyst in a small, high-impact team, you'll translate analytical requirements into scalable, secure technical solutions that serve stakeholders across the technology organisation.

KEY RESPONSIBILITIES

Platform Architecture & Development

• Design and build end-to-end web applications for the Strategic Intelligence Platform, spanning user interfaces, APIs, and backend services.
• Architect robust, scalable systems using API integrations, microservices, and serverless patterns that support AI/ML workflows and data processing.
• Develop automated workflows using low-code/no-code platforms and custom solutions to eliminate manual processes and scale analytical capabilities.
• Implement secure, scalable infrastructure on AWS — including Lambda, API Gateway, and databases — integrated with the Databricks analytics platform.

Data Pipeline & Integration Management

• Build and maintain data pipelines connecting multiple internal and external data sources to support AI workflows.
• Design RESTful APIs and integration patterns that enable seamless data flow between systems, databases, and analytical platforms.
• Enforce data governance and security best practices ensuring compliance with Flutter's data protection requirements.
• Manage SQL and NoSQL database systems supporting both operational workflows and analytical data storage.

DevOps & Production Management

• Own the complete SDLC — from design through deployment — including testing, monitoring, and maintenance of production systems.
• Implement CI/CD pipelines and automated deployment processes ensuring reliable, repeatable software delivery.
• Monitor system performance and drive optimisation strategies to maintain platform scalability and reliability.
• Uphold security standards and compliance requirements across all technical implementations.

AI/ML Integration & Implementation

• Integrate LLMs and generative AI APIs (AWS Bedrock, OpenAI, Azure OpenAI) and custom models into production applications.
• Build RAG architectures and AI application patterns that enable intelligent data processing and automated insight generation.
• Partner with the AI Analyst to translate analytical requirements into technical specifications and take proof-of-concepts to production.
• Implement prompt engineering and AI workflow orchestration to support automated content generation and data analysis.

EXPERIENCE REQUIRED

Must have:

• 3–5 years of full-stack development experience building and deploying web applications end-to-end across React/Vue, TypeScript/JavaScript, and Python or Node.js — with a proven ability to build clean, maintainable architectures.
• Cloud-native systems proficiency on AWS — Lambda, API Gateway, S3, EC2 — with a solid understanding of serverless design patterns and experience deploying production-grade systems.
• Database and API development experience across SQL and NoSQL databases, RESTful API design, and data integration patterns — with the ability to optimise data flows across distributed services.
• DevOps experience including CI/CD pipeline implementation, automated testing, and production system monitoring — with a track record of taking prototypes to production reliably and at scale.
• Comfortable with Git, Agile engineering practices, and translating ambiguous requirements into practical technical solutions quickly.
• Confident communicator — able to engage senior stakeholders, present technical options clearly, and adapt well in fast-moving environments.

Nice to have:

• AI/ML integration experience with LLMs and generative AI APIs (AWS Bedrock, OpenAI, Azure OpenAI), including working knowledge of RAG patterns and prompt optimisation.
• Databricks or equivalent data engineering platform experience, with familiarity of MLOps concepts and model lifecycle management.
• Advanced AWS certifications or equivalent cloud platform expertise.
• Experience in regulated industries — financial services, gaming, or similar — with an understanding of compliance requirements.

BENEFITS WE OFFER

• Hybrid Model: 2 office days/week with flexible leave policies, including maternity, paternity, and sabbaticals.
• Access to Learnerbly, Udemy, and a Self-Development Fund for upskilling.
• Career growth through Internal Mobility Programs.
• Comprehensive Health Insurance for you and dependents.
• Customised well-being programmes and a 24/7 helpline for holistic wellness.
• Sharesave Plan to purchase discounted company shares.
• Volunteering Leave and Team Events to build connections.
• Recognition through the Kudos Platform and Referral Rewards
