Job Description

ABOUT THE ROLE :

We are seeking an exceptional Functional Architect to operate horizontally across all four of our business sectors : Education, Commerce, Industrial, and Compliance.

This is not a siloed role you will own the functional system design fabric that stitches together business logic, domain models, and technical architecture across a diverse product portfolio.

The ideal candidate is AI-Native : someone who does not just use AI tools, but thinks through systems design with AI at the core.

A background that starts in technical architecture and evolves into functional mastery is the trajectory we prize.

We understand this is a rare profile and we are prepared to assess potential as much as current fit.

CORE MANDATE :

What You Own :

- Functional System Design : Define the functional architecture across all four domains Education, Commerce, Industrial, Compliance.

- Business Object Modeling : Identify, name, and formalize key business objects, entities, and their relationships across domains.

- Non-Functional Requirements (NFRs) : Own NFRs from Day 1 scalability, reliability, security, compliance, performance, and extensibility.

- Domain-to-Tech Bridge : Translate domain-specific business language and rules into structured functional specifications that engineering can act on.

- Cross-Domain Consistency : Establish shared vocabulary, data contracts, and design patterns that scale across all verticals.

KEY RESPONSIBILITIES :

Functional Design & Modeling :

- Lead functional architecture reviews across Education, Commerce, Industrial, and Compliance products.

- Create and maintain domain models, entity-relationship diagrams, and functional data flows.

- Define bounded contexts and integration patterns between domain modules.

NFR & Architecture Governance :

- Own a comprehensive NFR register from project inception not as an afterthought.

- Define architecture guardrails : latency, data residency, auditability, fault tolerance.

- Review and approve technical designs for functional compliance.

- Develop canonical data models that enable interoperability across sector platforms.

- Document functional specifications in collaboration with domain SMEs and engineering leads.

- Identify cross-cutting concerns (auth, audit logs, multi-tenancy) and design shared solutions.

- Champion AI-first architecture patterns agents, embeddings, retrieval augmentation.

Stakeholder & Domain Alignment :

- Serve as the functional authority in cross-functional product and engineering meetings.

- Partner with Product Managers across verticals to translate strategy into architecture.

- Facilitate domain modeling workshops with business owners.

- Identify gaps between business intent and technical implementation and resolve them.

AI-Native Capabilities :

- Design architectures that are AI-ready : modular, event-driven, and embedding-aware.

- Evaluate AI/ML tooling (LLMs, vector DBs, RAG pipelines) for fit within each domain.

- Prototype functional AI interactions : intelligent search, compliance co-pilots, adaptive UX.

- Maintain an AI capability map across the portfolio tracking where AI adds the highest ROI.

CROSS-DOMAIN SECTOR CONTEXT :

Sector :

- Education

- Commerce

- Industrial

- Compliance

QUALIFICATIONS :

Ideal Candidate Profile :

- Originated as a Technical Architect (software/systems design) and evolved into a Functional Architect this trajectory is highly valued.

- AI-Native mindset : actively designs systems with LLMs, agents, embeddings, and intelligent automation as first-class components.

- Proven experience creating domain models, entity-relationship diagrams, and functional specifications across complex B2B product ecosystems.

- Demonstrated NFR ownership : authored and enforced scalability, security, compliance, and performance requirements from project kickoff.

- Comfortable working across multiple business domains without deep domain expertise in each pattern recognition and fast context-switching are key.

- Strong communicator able to translate between business stakeholders and engineering teams with equal fluency.

Technical Foundation :

- API design (REST, GraphQL, event-driven)

- Data modeling : relational, document, graph

- Cloud architecture : AWS / Azure / GCP

- Microservices and domain-driven design (DDD)

- AI/ML infrastructure : vector DBs, RAG, agents

Functional Skills :

- Business process modeling (BPMN, UML)

- Functional spec authoring and review

- NFR frameworks and quality attributes

- Stakeholder facilitation and domain workshops

- Architecture decision records (ADRs)

WHY THIS ROLE?

What Makes This Unique :

- Horizontal mandate : you will have a birds-eye view of the entire product portfolio four sectors, dozens of platforms.

- Build the functional architecture practice from the ground up this is not a maintenance role.

- Work alongside AI-native product and engineering teams who value architectural rigor.

- Influence product strategy directly functional architecture shapes what can and cannot be built.

- Rare opportunity to apply AI-first thinking across industries : EdTech, Retail, Industrial, and Compliance
