Lead Software Engineer - Parametric

About the role

The Lead Software Engineer is responsible for providing technical leadership, project management, process development, training, and support across the Core Operations Platform.

This role is part of Parametric's hybrid working model, which includes working in the office 3 days a week and choosing to work remotely or in the office the remaining days of the week.

Primary Responsibilities

• Architect and lead development of a high-throughput, event-driven performance calculation engine on AWS, processing large volumes of financial data with accuracy and auditability requirements
• Drive the migration of the legacy performance reporting application stack onto a modern, cloud-native technology platform — defining migration strategy, sequencing, and risk mitigation
• Design scalable distributed systems using Python, Apache Kafka, PySpark, and AWS services (Lambda, Batch, Glue, Athena, S3, DynamoDB)
• Define and enforce data modeling standards, schema design, and data structure patterns appropriate for performance calculation use cases
• Maintain and plan for migration of existing legacy applications to a modern technology platform
• Establish observability, alerting, and runbook standards to ensure system reliability and auditability
• Deliver and engineer practice Lead Agile-based delivery: sprint planning, backlog refinement, and iterative delivery cadences
• Provide flexible, pragmatic solutions to complex business problems within firm technology standards and regulatory constraints
• Author and review technical design documents, ADRs (Architecture Decision Records), and runbooks
• Own and enforce code quality standards; conduct code and merge-request reviews
• Build comprehensive test coverage: unit, integration, functional, and performance tests
• Research and evaluate open-source technologies and cloud-native AWS services; drive adoption where justified
• People & Stakeholder Leadership Mentor and lead a global team of engineers; provide regular feedback, support career development, and foster an inclusive, high-performing engineering culture
• Partner with business analysts and stakeholders to translate complex financial requirements into technical specifications
• Collaborate cross-functionally with architecture, data platform, and infrastructure teams
• Communicate technical trade-offs and roadmap recommendations clearly to senior leadership
