Principal Software Engineer (AI & Data Products)

Accountabilities: As a Principal Software Engineer, you will serve as a technical authority responsible for architecture, engineering excellence, and the delivery of sophisticated software and AI solutions. You will translate strategic architectural direction into practical implementations, lead complex cross-functional initiatives, and ensure the long-term performance, scalability, security, and reliability of critical systems.

• Drive technical strategy and architectural decisions across one or more product lines, ensuring alignment with enterprise architecture, engineering standards, and business objectives.

• Own end-to-end product-line architecture, designing scalable, reliable, secure, and maintainable systems that follow broader organizational guidelines.

• Translate high-level architectural strategies into actionable technical designs and implementation plans for engineering teams.

• Lead complex, high-impact technical initiatives involving multiple teams, systems, and product components.

• Establish and reinforce engineering best practices, architectural patterns, and design standards to ensure consistency and quality across teams.

• Collaborate with architects to implement and refine technical direction, providing feedback based on practical engineering constraints and production system behavior.

• Resolve highly complex technical challenges involving system scale, ambiguity, performance, and cross-team dependencies.

• Lead architectural and design reviews, evaluating solutions against long-term scalability, performance, reliability, and maintainability requirements.

• Influence technical prioritization and engineering trade-offs, balancing business needs with architectural standards and long-term objectives.

• Mentor and develop senior and staff-level engineers, strengthening technical decision-making, system design capabilities, and engineering excellence.

• Identify and address systemic risks, technical debt, performance bottlenecks, and operational inefficiencies across product lines.

• Drive improvements in system reliability, observability, monitoring, and operational excellence.

• Evaluate and introduce new technologies, ensuring their adoption supports architectural standards and long-term technical strategy.

• Champion application security by implementing security strategies, identifying vulnerabilities, and coordinating remediation efforts based on security scans and penetration testing results.

• Collaborate with Product, Quality Assurance, Support, Cloud, Architecture, Infrastructure, and Data Science teams to ensure cohesive delivery and high-quality outcomes.

• Act as the primary technical authority for assigned product lines, designing transformative solutions with broader organizational impact.

• Architect reliable data pipelines with clearly defined data contracts, schema evolution strategies, end-to-end data lineage, versioning, and idempotent processing.

• Build and productionize document processing and information extraction pipelines, agentic AI applications, and automated evaluation frameworks.

• Establish end-to-end observability across data quality, pipeline reliability, model performance, and inference costs, including longitudinal metrics and automated regression detection.

• Optimize model selection and inference orchestration to balance output quality, latency, throughput, and operational costs.

• Partner with Data Science, Architecture, and Infrastructure teams to develop reusable engineering patterns, shared tools, and clear operational ownership.
