iGaming:
If it’s iGaming, we know a thing or two. At Light & Wonder, It’s all about the games, and our digital team leads the global iGaming market, providing jaw-dropping content and innovative software that powers the world's most successful online gaming providers.
Position Summary
The Senior Software Architect is a senior technical leadership role within the iGaming Platform team. This is not a "heads-down coding" role, nor is it a purely advisory one — it sits at the intersection of hands-on delivery and architectural ownership. You will be expected to make and defend design decisions, lead cross-team technical alignment, and ensure the platform scales, integrates, and operates reliably at global scale.
You bring established architecture experience, deep software engineering instincts, and the credibility to influence without authority across multiple platform portfolios. You will contribute to the Architecture Review Board (ARB), own Architectural Decision Records (ADRs), and play a central role in shaping how the OpenGaming platform evolves.
Own and produce Architectural Decision Records (ADRs) for significant design decisions, ensuring rationale, context, and consequences are documented and retained
Participate actively in the Architecture Review Board (ARB), reviewing solution designs across platform portfolios and applying the L&W Architectural Standards
Define and enforce architecture patterns, integration contracts, and non-functional requirements (NFRs) across the Nova platform and adjacent systems
Contribute to the Tech Atlas, Asset Registry, and governance artefacts that underpin L&W's architecture practice
Lead threat modelling exercises using structured approaches (STRIDE, Threagile) and translate outcomes into actionable security requirements
Produce high-quality solution designs — from C4 context and container diagrams through to component and sequence-level detail — that can be directly implemented by engineering teams
Design and evolve RESTful and event-driven APIs using OpenAPI specifications, establishing contracts that support independent team delivery
Architect integrations with third-party systems including payment providers, identity services, regulatory reporting endpoints, and operator platforms
Provide technical governance over CI/CD pipeline design, environment architecture, and deployment strategies using GitHub Actions, Kustomize, and ArgoCD
Hands-on prototyping and proof-of-concept development when needed to de-risk architectural decisions
Define and champion non-functional standards: performance baselines, resilience patterns, observability requirements, and security controls
Lead or contribute to performance and load testing design, interpreting results in the context of SLAs and platform growth targets
Establish and evolve coding and integration standards across Java/Spring services on the platform
Drive adoption of structured security practices through the Security Champions programme and DevSecOps tooling integration
Provide technical mentorship to Associate and mid-level architects and senior engineers, building architectural thinking across the team
Translate complex technical positions into clear, concise communication for delivery leads, product managers, and executive stakeholders
Drive alignment between iGaming and wider L&W engineering teams on shared concerns: API strategy, data platforms, observability, and shared services
Participate in hiring and technical assessment processes for engineering and architecture candidates
Qualifications
Degree in Computer Science, Software Engineering, or a related technical discipline, or demonstrably equivalent experience. Professional certifications (AWS, Azure, GCP) are valued but not a substitute for practical architecture experience.
7+ years in software engineering with at least 3 years in an explicit architecture role — designing systems, not just building them
Proven track record of owning architectural decisions end-to-end: from initial discovery and option analysis through to documented ADR and post-implementation review
Strong Java/Spring Boot background with demonstrable experience designing cloud-native microservices at scale
Experience designing and operating event-driven systems using Kafka or equivalent messaging platforms
Hands-on exposure to API gateway technologies and federated API management across multiple consumer profiles
Experience operating in a regulated or compliance-driven environment (gaming, fintech, payments, or similar)
Demonstrable experience working within or contributing to a governance process — ARB, design authority, technical steering, or equivalent
Comfortable producing architecture artefacts independently: C4 diagrams, ADRs, threat models, NFR matrices
