• Define modernisation roadmaps for product applications, including target-state architecture for services, infrastructure, and data flows. • Assess legacy components to identify modernisation opportunities, technical debt, and pragmatic remediation paths. • Determine appropriate modernisation approaches including refactoring, re-platforming, or re-architecting based on performance, cost, risk, and delivery considerations. • Contribute architectural insight to the modernisation business case and support financial modelling related to infrastructure and platform decisions. • Implement modernisation changes directly within product codebases, including refactoring legacy components and decomposing monolithic architectures. • Introduce cloud-native engineering patterns such as microservices, event-driven architecture, containerisation, and serverless services. • Identify and implement performance, scalability, and reliability improvements using observability platforms, cloud metrics, and logging tools. • Develop reference implementations and engineering patterns that enable teams to accelerate modernisation across products. • Improve the operational and platform capabilities that support Entersekt’s SaaS delivery model. • Reduce reliance on manual operational processes and bespoke scripts by introducing automation across tenant lifecycle management. • Design and implement repeatable processes for tenant provisioning, configuration, and environment management. • Improve onboarding speed for new tenants through standardised workflows and environment templates. • Establish tenant-aware observability by improving consistency of logs, metrics, traces, dashboards, and alerting across services. • Contribute to multi-tenant architecture design, including tenant isolation and service tiering considerations. • Improve deployment consistency through repeatable deployment patterns, automation, and safer release processes. • Introduce practical engineering guardrails that support modern development practices including API-first design, event streaming, cloud-native storage, and container orchestration. • Define and maintain architectural standards, patterns, and best practices for cloud-native development. • Contribute to cloud governance initiatives and participate in architecture reviews that guide engineering teams through modernisation efforts. • Lead technical workshops, architecture discussions, and design reviews across product teams. • Support engineering teams in translating modernisation objectives into practical implementation changes. • Partner closely with DevOps, Platform Engineering, Cybersecurity, Compliance, and Product teams to ensure modernisation initiatives align with operational and regulatory requirements. • Build trust with engineering teams by introducing modern practices through collaborative design and working reference implementations. • As the modernisation programme evolves, contribute to shaping a small, specialised engineering capability that supports broader platform modernisation initiatives. • Maintain a strong hands-on focus while helping teams adopt new patterns and technologies.

• You will design, architect, and build the core system — a stateful, multi-layer architecture spanning data ingestion, decision logic, and AI-powered delivery • You will establish the norms, the workflows, and the standards for how AI-native development actually works at scale on a small team • You will own the full technical vision and be accountable for it • Establish an AI-native development culture: AI tools as the default, human judgment as the filter • Hire and mentor a small senior team (2–3 Product Engineers) as the product scales from v1 to v2

• Product Surfaces • Student-facing product interfaces — the core user experience that learners interact with daily • Real-time features that surface AI intelligence in ways that feel immediate and useful, not mechanical • Responsive, performant UI built on a shared component library • Backend & AI Integration • API routes and backend services connecting the user interface to the intelligence and data layers • AI orchestration integration: streaming responses, agent outputs, structured recommendations in context • Event-driven ingestion pipelines that translate platform activity into structured, reliable signals • Data & Infrastructure • Storage architecture and schema design for persistent user state — built to evolve as the product grows • Deployment infrastructure, CI/CD, and environment management — no dedicated DevOps to hand off to • Data access controls and audit logging that satisfy institutional security and compliance requirements • Quality & Velocity • End-to-end feature ownership from spec to production — including testing, monitoring, and iteration • Active use of AI-assisted development tooling to maintain high output without sacrificing code quality • Contribution to shared component libraries and codebase standards as the team grows • Stay on the bleeding edge of the AI ecosystem — Claude Code, Cursor, OpenAI Agent SDK, MCPs, and whatever comes next. • When a better way to build exists, find it and bring it in. • Please include a link to your portfolio/GitHub as part of your application.
