Application Architect - Enterprise & AI

About The Position

This is a delivery-focused architecture role for someone who loves turning complex business problems into working technical solutions. As an Application Architect, you’ll be the technical lead on product and platform initiatives — taking requirements from product and engineering and designing the systems needed to deliver them. You’ll work closely with delivery teams, product owners, and engineering leads, making the architecture decisions that keep initiatives on track and technically sound. You’ll be embedded in delivery — shaping how AI-enabled features, integrations, and services are designed and built responsibly, with security and compliance embedded from the start.

Requirements

5–10 years in software engineering, with meaningful experience in solution or technical architecture roles on multi-team delivery programs
Solid cloud architecture experience on AWS — services, networking, data, and security patterns in a delivery context
Hands-on experience designing and integrating AI-powered features — including LLMs, RAG patterns, and agentic workflows
Strong integration design skills — APIs, event-driven systems, service boundaries, and resilience patterns
Good working knowledge of backend services (Java ecosystem preferred), data systems, and front-end integration points
Experience in regulated environments (PCI/PII) and comfort embedding compliance requirements into design
Able to produce clear architecture artefacts: component diagrams, sequence diagrams, ADRs, and integration specs
Makes things clear and builds trust quickly with delivery teams.
Writes well — your design docs are readable, your assumptions are explicit, and your trade-offs are explained.
Excited about AI’s potential in product but grounded about what that means in practice.

Nice To Haves

Mentorship from the Principal Architect.
Architecture community of practice.
External development support through cloud certifications (AWS Solutions Architect Professional), architecture frameworks (TOGAF), and attendance at relevant industry events and conferences.

Responsibilities

Solution design for your initiatives. You translate product and business requirements into clear, well-reasoned technical designs — component diagrams, integration specs, data models, and sequence flows that engineering teams can build from. You work within enterprise reference architecture, applying the right patterns for the problem at hand.
AI & agent implementation design. You design AI-enabled features and workflows within your initiatives: LLM integrations, agentic flows, retrieval-augmented generation (RAG), and tool-use patterns. You make these capabilities concrete, buildable, and production-ready — informed by the architectural standards set at enterprise level.
Integration & API design. You define how your solution integrates with surrounding services, APIs, event-driven systems, and external platforms — with clear contracts, resilience patterns, and well-understood boundaries.
Security & compliance by design. In partnership with AppSec and risk functions, you ensure security controls, PCI/PII requirements, and responsible AI practices are embedded in solution design — not retrofitted during delivery.
Technical governance within delivery. You guide and review engineering work throughout the build — attending design sessions, reviewing pull requests where it matters, and helping teams navigate technical decisions without creating bottlenecks.
Estimation & gate input. You produce Gate 0 (ROM) and Gate 1 (detailed) architecture estimates for your initiatives, with clearly documented assumptions, risk flags, and dependency inventories that product and portfolio teams can plan from.
