Senior Software Architect

The Architecture organisation provides technical direction and guidance across domain PODs, SRE, Data, and Infrastructure teams. As Senior Architect, you will influence how we design resilient, scalable, and cost-efficient systems. NET Core, Azure, Kubernetes, and modern DevOps practices.

Responsibilities:

• Define and document target architecture blueprints and patterns for. NET Core microservices, React/React Native frontends and Azure cloud infrastructure.
• Guide the design of high-availability, low-latency systems, including API gateways, messaging architecture, caching strategies, and circuit breaker patterns for trading platforms.
• Establish observability standards: structured logging, distributed tracing, metrics, SLOs, and alerting practices across the organisation.
• Lead architecture reviews, threat modelling, and Proofs of Concept for significant initiatives, evaluating technology choices and design trade-offs.
• Advise on Kubernetes (AKS) strategies, containerization, container registries, and deployment patterns (GitOps, blue-green, canary).
• Define infrastructure-as-code standards, CI/CD pipeline architecture, and DevOps tooling to enable safe, fast deployments.
• Guide data architecture decisions across SQL Server, Cosmos DB, Databricks, and data lake storage for transactional and analytical workloads.
• Partner with Security and Compliance teams on architectural security, regulatory requirements, and audit- friendly designs.
• Mentor senior engineers, architects in training, and technical leads to grow architectural maturity across the organisation.

Requirements:

• Deep knowledge of. NET Core microservices, Domain-Driven Design (DDD), Clean Architecture, CQRS, and event-driven design patterns.
• Expert-level Azure experience: App Services, AKS (Kubernetes), Service Bus, Event Grid, API Management, Cosmos DB, SQL Database, Key Vault, Storage, and monitoring (Application Insights).
• Strong Kubernetes/AKS expertise: cluster design, networking, security (RBAC, network policies), resource management, autoscaling, and GitOps principles (FluxCD, ArgoCD).
• Solid understanding of DevOps: CI/CD pipelines (Azure Pipelines, GitHub Actions), infrastructure-as-code (Terraform, ARM templates), containerization (Docker), and deployment patterns.
• Experience designing resilient systems: circuit breakers, retries, bulkheads, timeouts, fallbacks, and chaos engineering practices.
• Strong grasp of observability: structured logging, distributed tracing (Application Insights, OpenTelemetry), metrics (Prometheus), and alerting (e. g., Azure Monitor, Datadog).
• Knowledge of security architecture: API security (OAuth2 JWT, mTLS), secrets management, encryption, and defence-in-depth strategies.
• Experience with data architecture patterns and considerations (OLTP/OLAP, relational/NoSQL, eventual consistency).
• 7-14 years of software engineering with significant architectural leadership and hands-on technical depth.
• Proven track record architecting and operating large-scale, distributed systems in production (ideally fintech, trading, or other mission-critical domains).
• Strong ability to communicate complex architecture and design decisions to both technical teams and executive stakeholders.
• Demonstrated influence over organisational practices, standards, and technology choices across multiple teams and geographies.
• Comfort with ambiguity and ability to evaluate trade-offs between innovation, performance, cost, and regulatory requirements.
