• High-Complexity Development: Provide technical leadership in implementing high-complexity and high-criticality features and solutions within the GB Finance domain, acting as the squad's primary hands-on implementer. • Code Quality and Testing: Write clean, efficient, and secure code; actively participate in code review rituals and ensure adequate coverage of unit, integration, and regression tests for developed features. • Information Security: Apply Information Security policies (Security by Design) throughout the development lifecycle, perform risk analyses and ensure solutions comply with internal and regulatory guidelines. • Production Support: Serve as a technical reference for product support in production, leading investigation and resolution of high-complexity incidents and issues (troubleshooting) to ensure system stability and availability. • Optimization and Performance: Collect and analyze performance metrics, using observability tools (tracing, logs) to identify bottlenecks and propose/implement solutions that optimize system efficiency and scalability. • Architectural Collaboration: Actively collaborate with Specialists and Tech Leads on solution planning and architectural design, focusing on technical feasibility, sustainability, and maintainability. • Innovation and AI: Explore and implement technological innovations that add value to GB Finance products and processes, including applying Artificial Intelligence concepts to improve solution efficiency and intelligence. • Mentoring and Technical Reference: Act as a technical reference point for the team, actively promoting improvements in code quality, design, and services (informal mentoring of Mid and Junior developers). • Documentation: Develop and maintain detailed technical documentation, ensuring a solid knowledge base is available for reference and consultation.
• Own solution and AI architecture: RAG, AI agents, and LLM-enhanced systems that are observable, testable, and governable — not demo-only. • Define model and data lifecycle from experiment through PoC, pilot, and production: evaluation, drift signals, retention, and classification aligned with security stakeholders. • Run hands-on feasibility work using agentic workflows: targeted PoCs (retrieval stacks, evaluation harnesses, integration spikes) driven through Cursor/Claude Code and AFA where applicable. • Define non-functional requirements and manage technical risk and debt: latency, scale, resilience, security, and cost — with mitigations and sequencing captured in ADRs and fitness assessments. • Create architecture artifacts in Git: C4 and data-flow views as diagram-as-code; infrastructure context with the Cloud Architect; UML or equivalent views where tooling generates them from models or code; threat models as structured, reviewable repository content — not unmanaged documents. • Harden and evolve AFA Cursor rules, agent skills (e.g., design-new-service, evaluate-design, review-pull-request patterns), and sub-agents so AI, API, security, and data standards match Pearson and ELL composable architecture expectations. • Define data architecture: logical and physical models as schemas, migrations, and manifests; SQL/NoSQL choices matched to access patterns and privacy constraints. • Shape DevSecOps and quality with the Cloud Architect, DevOps, and QA: CI/CD gates, contract and test expectations; architecture- and security-focused review using AFA pull-request verdict workflows alongside human reviewers. • Set performance budgets and evaluation criteria; support profiling, tracing, and tuning. • Work in Agile delivery: ADRs and Design Decision Records, spikes, and explicit trade-offs with product, security, infrastructure, and customer stakeholders. • Deliver early outcomes: current-state and target-state architecture for an active initiative, expressed as diagram-as-code and ADRs (trust boundaries, non-functional requirements); a prioritized roadmap; threat artifacts for sensitive paths; and clear handover criteria with the Cloud Architect, QA, and DevOps.
