Management System Engineer – Contract
Remote – United States
$90–$120/hour
Certus Recruitment is partnering with a rapidly growing Wealth Management / FinTech business building a modern investment platform from the ground up.
We're looking for an experienced Position Management System Engineer to take ownership of one of its most critical components – the real-time system of record for client holdings, transactions, tax lots and market values.
This is a genuine greenfield engineering opportunity.
You won't be maintaining or patching a 15-year-old legacy platform. You'll help design, build and own the position engine that the firm's trading and investment infrastructure will depend on.
The platform brings together custodian data, order fills, money movement, pricing and security reference data to create a normalized, real-time view of portfolios across multiple custodians.
What you'll be working on:
• Building and extending a greenfield real-time position engine
• Converting an append-only ledger into normalized positions
• Building event-driven pipelines that update holdings as transactions occur
• Integrating custodian feeds including Schwab, Fidelity and Pershing
• Developing continuous position reconciliation and break detection
• Integrating real-time and near-real-time market pricing
• Building the security master across equities, fixed income, options and other instruments
• Handling cost basis, tax lots, cancel/rebook activity and transaction corrections
• Owning the platform in production – monitoring, reliability, capacity and incident response
What we're looking for:
✓ 5+ years' relevant engineering experience
✓ Hands-on experience with position management, portfolio accounting, books & records or closely related investment infrastructure
✓ Experience within a broker-dealer, clearing firm, RIA, custodian, wealth management platform or relevant FinTech
✓ Strong understanding of cost-basis accounting and cancel/rebook semantics
✓ Event-driven / streaming systems experience
✓ Strong Python and SQL
✓ Understanding of event-time processing, at-least-once delivery, deduplication, checkpointing and state management
✓ A builder mentality and desire to own a mission-critical system end-to-end
Technical environment: AWS, ECS Fargate, Aurora PostgreSQL, S3, Lambda, SNS/SQS, EventBridge, Python, SQL, CDK and CodePipeline.
Experience with corporate actions, bitemporal/point-in-time modelling, Materialize, Flink or similar streaming technologies would be a bonus.
The real attraction here is ownership.
If you've spent your career working with investment infrastructure and want the opportunity to build a position-management platform properly from the ground up, this is a chance to have meaningful influence over the architecture, data model and technology decisions from an early stage.
