HOS: Technical Architect - Sr / Lead

Key Responsibilities

• Design, build, and evolve core frameworks and reusable platform components.
• Perform hands-on coding for technology upgrades and migrations (Java/Spring/Jakarta/Tomcat and related platform components).
• Own and drive large-scale modernization initiatives across services and shared libraries.
• Build and evaluate POCs to assess new technologies, patterns, and platform capabilities.
• Resolve complex technical issues across frameworks, distributed services, and integration layers.
• Ensure implementation alignment with platform and enterprise architecture.
• Define, review, and enforce coding standards, framework usage policies, and technical guidelines.
• Mentor architects, tech leads, and engineers; guide design and code quality decisions.
• Drive adoption of emerging technologies including AI-assisted development, cloud-native tooling, and observability practices.
• Collaborate with architecture, product, and engineering stakeholders for execution and delivery alignment.

• Strong Java proficiency across mixed runtimes (legacy and modern), with migration ownership toward modern LTS baselines (JDK 11+, preferably JDK 17).
• OOP concepts, SOLID principles, and design patterns.
• Spring Framework, Spring Boot, Spring MVC, and Spring Security.
• RESTful API design and implementation.
• JPA and Hibernate.

• Strong API governance and specification experience using Swagger/OpenAPI.
• Experience with event-driven architecture and messaging patterns: Kafka producers/consumers, event contracts, serialization formats (JSON, Avro).
• Strong validation and business-rule enforcement patterns in API and service layers.
• Security and authentication implementation including OAuth2, JWT, and API security best practices.

• Hands-on No-SQL and relational database experience (PostgreSQL preferred; MongoDB/Cassandra exposure is valuable).
• Strong database schema evolution practices using versioning/changelog approaches (Liquibase).

• Strong experience in framework/platform-level development (not only feature-level application coding).
• Proven experience in migration and upgrade programs across core platform components.
• Experience with application container runtimes and deployment packaging patterns (Tomcat, containerized deployments).
• AWS ecosystem exposure (preferred).
• Docker containerization.
• CI/CD pipelines with Jenkins and Git-based workflows.
• Kubernetes/EKS and Helm-based deployment patterns (preferred).

• Strong debugging, performance analysis, and production problem-solving capabilities.
• Experience working in Agile development environments.
• Strong communication, cross-team collaboration, and technical leadership capability.
• Proficiency with AI-assisted development tools (e.g., GitHub Copilot or similar) for productivity, code quality, and accelerated delivery.

• Front-end ecosystem awareness in JavaScript/TypeScript-based environments.
• Observability tooling and SRE-aligned engineering practices.

This role spans two product platforms:

• Java backend (custom IoC/DI framework, Tomcat WAR deployment, Kafka clients, AWS SDK).
• Jakarta XML Bind, Swagger/OpenAPI, PostgreSQL, JWT/OAuth2 (AWS Cognito).
• Ember.js / TypeScript frontend with Webpack build tooling.
• AWS-native CI/CD (CodeBuild, CodePipeline, CloudFormation, ECR).

• Java 17, Spring Boot, Spring MVC, Spring Security.
• Kafka event-driven architecture (producers/consumers, Avro/Glue-Avro serialization, configurable event topics).
• Springdoc/OpenAPI, Swagger UI, RESTful APIs.
• JPA/Hibernate, PostgreSQL, Liquibase-managed schema evolution.
• Quartz/custom scheduler framework and @Scheduled jobs.
• Multi-tenant datasource/filter/security patterns.
• Dockerized builds, Jenkins CI/CD pipelines, AWS ECR, Helm deployment assets.
