Technical Architect

Job Description
Job Title: Technical Architect
Location: Pune | Hybrid / On-site
Experience: 12–15 Years
Employment Type: Full-time
Role Type: Horizontal Role – Cross-Domain | Independent Contributor | Hands-on Technical Expertise
About The Role
We are looking for an experienced Technical Architect to drive technical architecture and engineering excellence across four business sectors: Education, Commerce, Industrial, and Compliance.
The ideal candidate will have deep expertise in software design patterns, system architecture, distributed systems, and enterprise application development. The role requires the ability to independently lead complex technical initiatives from design through delivery and create detailed, actionable technical artifacts for engineering teams.
The candidate should be hands-on and capable of developing proof of concepts (PoCs), writing sample code, and validating architectural decisions whenever required. Experience with AI/ML systems, LLMs, and intelligent automation will be a significant added advantage.
Roles And Responsibilities
Define and drive technical architecture across Education, Commerce, Industrial, and Compliance business domains.
Independently lead technical design and execution of complex, cross-functional engineering projects.
Create and maintain system context diagrams, architecture diagrams, data flows, database schemas, sequence diagrams, and API contracts.
Define bounded contexts, integration patterns, and architectural standards for distributed systems and enterprise applications.
Apply software design patterns, including creational, structural, and behavioral patterns, to build scalable and maintainable applications.
Own non-functional requirements (NFRs), including scalability, performance, security, reliability, compliance, and extensibility.
Develop technical proof of concepts, prototypes, sample implementations, and high-quality code to validate architectural decisions.
Prepare and maintain Architecture Decision Records (ADRs) and detailed technical specifications.
Review and approve technical designs, code, and pull requests to ensure architectural compliance.
Identify cross-cutting concerns such as authentication, authorization, audit logging, and multi-tenancy, and define reusable solutions.
Define architecture guardrails for latency, fault tolerance, data residency, auditability, and system reliability.
Collaborate with Product Managers, engineering leads, and business stakeholders to translate product requirements into actionable technical solutions.
Identify gaps between business objectives and existing technical capabilities and independently drive solutions.
Evaluate APIs, data models, cloud infrastructure, and integration strategies across multiple product platforms.
Assess AI/ML tools, LLMs, vector databases, RAG pipelines, and AI agents for potential enterprise integration.
Provide technical guidance for intelligent search, automation pipelines, and AI-enabled product capabilities.
Adapt to different technology environments and business domains while maintaining consistent architectural standards.
