We are seeking a

Senior Software Engineer
to join our Unified Platform (UP) team. UP consolidates data and technologies into a comprehensive solution, accelerating time to market. Optimizing decision-making and research, our platform simplifies implementing new ideas, enhancing our competitive edge. The UP-Finance team is responsible for building and operating the systems that underpin DRW's financial accounting, regulatory reporting, reconciliation, and cost basis infrastructure. This team is looking for application software developers who can help with our broad set of challenges.

Broadly, the development teams at DRW believe in rapid deployment and feedback, automated testing, and cohesive, transparent, lightly-coupled service architectures. Our systems span the full lifecycle from PnL calculation, general ledger classification, financial reporting and regulatory capital reporting. 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. You break large, ambiguous problems into small increments and ship continuously.

You want to understand why the numbers matter, not just how to move them through a pipeline. You're comfortable leading a project end-to-end: discovery, architecture, stories, implementation, deployment and support.
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. 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)
~ Deep Python expertise - data pipelines, scheduling, tooling.

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
The position is also eligible for an annual discretionary bonus. In addition, DRW offers a comprehensive suite of employee benefits including group medical, pharmacy, dental and vision insurance, 401k (with discretionary employer match), short and long-term disability, life and AD&D insurance, health savings accounts, and flexible spending accounts.
