Westbury Partners – Sydney NSW

Full time

4d ago , from E-Financial Careers Australia

Own and modernise critical trade operations infrastructure, driving reconciliation, clearing, regulatory reporting, data integrity, automation, and resilient technology across complex financial systems and global teams.

What You'll Do:

• Take ownership of the technology infrastructure behind critical trade operations. You’ll work across reconciliation, clearing, managed-account operations, regulatory reporting, databases, ETL pipelines, cloud infrastructure, and deployment environments.
• You’ll inherit an established but diverse technology landscape and play a key role in stabilising, documenting, automating, and continuously improving the systems that support trading operations and business growth.

Your responsibilities will include:

• Build and maintain reconciliation processes across multiple brokers, formats, and operational workflows.
• Detect, investigate, and resolve trade breaks and discrepancies.
• Support clearing operations across futures, equities, and FX.
• Manage monthly rebalancing, allocations, and fee calculations for managed accounts.
• Maintain data integrity across positions, trades, fees, and allocations in PostgreSQL.
• Develop and maintain regulatory reporting processes, including market-specific requirements and tagging.
• Generate and deliver NAV files to fund administrators.
• Build and support ETL pipelines spanning FTP, S3, Kafka, and batch processing.
• Develop monitoring, alerting, debugging, and replay capabilities across distributed systems.
• Manage containerised deployments, CI/CD pipelines, image repositories, and infrastructure across cloud and on-premise environments.
• Collaborate with brokers, administrators, operations teams, and trading desks across multiple international time zones.
• Contribute to the development of a consolidated, reliable trade-data architecture.

Why Join Us:

This is an opportunity to own systems where engineering decisions have a direct impact on operational performance, regulatory compliance, data quality, and the organisation’s ability to launch and scale new strategies.

You’ll have genuine ownership across application development, data engineering, infrastructure, automation, and production support rather than being confined to a single technical silo.

About You:

• 8+ years of experience in a comparable engineering, trade operations, or financial technology role.
• Strong Kafka knowledge, including producers, consumers, consumer groups, offsets, and event-driven architectures.
• Proven reconciliation experience across multiple systems and counterparties.
• Practical understanding of regulatory reporting and financial-market requirements.
• Strong Docker and CI/CD experience, including GitLab, Nomad, and Artifactory.
• Solid PostgreSQL and database-integrity experience.
• Comfortable working with Python and navigating polyglot environments.
• Go and/or Java reading proficiency is highly desirable.
• Experience with Kafka Streams or comparable stream-processing technologies is advantageous.
• AWS experience across services such as S3, EC2, and EKS is beneficial.
• Fund administration experience is a plus.
• Confident communicating with stakeholders across Sydney, London, and New York.
