- We are looking for a hands-on Technical Lead and Senior Full-Stack Engineer who can build across the front end, back end, experience engine, and AI/ML layers and establish the engineering foundations required to deliver them reliably.
- In this role, you will remain hands-on across the full technology stack—from React/Next.js user experiences and experience orchestration to Java/Spring Boot services, APIs, Kafka events, and data integration using REST API via Apigee. You will also be able to establish cloud infrastructure, development environments, and CI/CD pipelines, working with enterprise platform teams where shared services or controls are involved.
Key Responsibilities
As a Technical Lead, you will remain hands-on across the entire technology stack while guiding engineering excellence and delivery outcomes. You'll:
- Design, develop, test, and deploy scalable digital solutions using modern front-end and back-end technologies
- Build customer-facing experiences using React, Next.js, and TypeScript
- Develop robust Java/Spring Boot services, REST APIs, microservices, and event-driven architectures
- Create reusable components, integration patterns, and platform capabilities
- Establish and maintain cloud infrastructure, CI/CD pipelines, and Infrastructure-as-Code solutions using Terraform
- Deliver AI-powered and agentic product capabilities including RAG, prompt engineering, structured outputs, tool integrations, evaluations, monitoring, and governance frameworks
- Implement automation across unit, integration, API, performance, accessibility, and security testing
- Lead technical reviews, mentor engineers, and partner with Solution Architects to drive high-quality outcomes
- Improve system observability, resiliency, security, and operational readiness across enterprise platforms.
Required Qualifications, Experience, and Skills for this Role
- 8+ years of experience building and supporting enterprise-scale digital products
- Proven experience as a Technical Lead, Staff Engineer, or Senior Full-Stack Developer
- Strong expertise in:
- TypeScript
- React
- Next.js
- Java
- Spring Boot
- Experience with:
- REST APIs
- GraphQL
- Event-driven architectures
- Microservices
- CI/CD
- Terraform
- Containers and Kubernetes
- Hands-on cloud experience (Azure preferred; AWS experience considered an asset)
- Strong understanding of quality engineering, test automation, and secure software development practices
- Experience using AI-assisted engineering tools such as GitHub Copilot, Claude Code, or similar platforms
- Experience delivering AI/ML-enabled applications and intelligent product features in production environments.
Standout Skills
- API Gateway technologies and headless content platforms
- Feature flagging, experimentation, analytics, and personalization
- Okta/Auth0 and Customer Identity & Access Management (CIAM)
- Financial Services, Insurance, or other highly regulated industry experience
- Experience with LangGraph, CrewAI, Microsoft Agent Framework, MCP, and agent-to-agent integrations
Ideal Resource for this Role
will help shape the future of digital experiences by delivering secure, accessible, resilient, and AI-powered customer journeys. You'll influence engineering standards, accelerate delivery velocity, and drive innovation while maintaining enterprise-grade quality and governance.
