Job Summary:
DRW is a diversified trading firm with over 3 decades of experience bringing sophisticated technology and exceptional people together to operate in markets around the world. They are seeking a Senior Software Engineer to join their Unified Platform team, responsible for building and operating systems that support DRW's financial accounting and regulatory reporting.
Responsibilities:
• Delivering on major regulatory, ERP, and financial reporting initiatives
• Migrating infrastructure to Kubernetes and modernizing our deployment practices
• Modernizing observability and monitoring across the finance platform
• You'll spend time upfront with accountants, financial analysts, and operations teams to deeply understand business problems, help stakeholders articulate requirements and test assumptions, then turn that into an architecture and a plan.
• You'll drive your project forward day-to-day, breaking big business requirements into shippable increments and delivering iteratively.
• You'll also spend time reviewing code, providing feedback on design documents, unblocking teammates, and participating in a support rotation.
Qualifications:
Required:
• 5+ years of professional software development experience
• Strength in at least one of Clojure or Python. We have a large Clojure codebase and a growing Python footprint across data pipelines. Experience with Ruby and PL/SQL is also valuable.
• Experience in the finance or accounting domain. You've worked with concepts like PnL, reconciliation, general ledger, regulatory reporting, or cost basis. You don't need to be a CPA, but you should be someone who leans into understanding the business.
• Strong system design skills. You can reason about architectural tradeoffs, distributed systems, and design for reliability and operability
• Solid understanding of relational databases: transactionality, indexing, performance tuning, and data modeling
• Experience building and operating production systems with modern infrastructure (containers, CI/CD pipelines, orchestration)
• A track record of mentoring engineers and contributing to engineering culture and the ambition to grow your technical leadership further
Preferred:
• Deep Python expertise — data pipelines, scheduling, tooling. This is an opportunity to have outsized impact.
• Experience with Clojure or other Lisp-family languages
• Hands-on experience with observability tooling — structured logging, metrics, alerting, anomaly detection
• Familiarity with Oracle, Kafka, or Airflow
• Experience with Kubernetes, Docker, and infrastructure-as-code
• Background in reducing operational toil through automation and better system design
