Overview:
The Technical Lead is responsible for owning the technical execution and engineering delivery of complex application and AI-enabled solutions across the software development lifecycle. This role serves as the primary technical authority for the engineering team, translating architecture and business requirements into executable technical plans, ensuring delivery quality, and guiding engineers through implementation.
The Technical Lead manages the day-to-day technical delivery of engineering teams comprising junior, mid-level, and senior software engineers, working closely with Forward Deployed Engineers (FDEs) on customer-driven solution implementation and Technical Program Managers (TPMs) on delivery planning, milestone tracking, and dependency management.
The role requires strong expertise in system design, cloud-native development, AI application integration, engineering quality practices, and technical mentoring, with accountability for technical stability, delivery predictability, and implementation excellence.
Responsibilities:
- Own the technical execution of software delivery across engineering workstreams, ensuring alignment with business requirements and solution architecture
-
Break down high-level architecture into implementable technical components, APIs, services, and engineering tasks
-
Lead system design discussions across application, data, and integration layers
-
Define and enforce engineering standards across development, testing, deployment, and documentation
-
Guide and support SDE1, SDE2, and SDE3 engineers in implementation, debugging, and technical problem-solving
-
Conduct code reviews and ensure adherence to coding standards, maintainability, and architectural integrity
-
Collaborate with FDEs on AI application integration patterns including LLM workflows, RAG pipelines, and agent orchestration
-
Work with TPMs to support effort estimation, technical dependency planning, and delivery sequencing
-
Identify technical risks early and define mitigation strategies across system design, integrations, and delivery execution
-
