Senior Python Engineer

We’re working with a high-growth financial technology company building the infrastructure behind modern digital investing platforms. Their systems operate at large scale, handling real-time financial workflows, market connectivity, and data pipelines that support millions of end users globally.

They’re looking for a Senior Software Engineer to join a core engineering team focused on real-time portfolio automation, market connectivity, and data‑intensive services running in the cloud.

What You’ll Be Working On

• Designing and building distributed, event-driven services for financial workflows
• Developing integrations with external market and execution platforms
• Building data ingestion and transformation pipelines for high-volume financial data
• Designing and maintaining RESTful APIs used by internal teams and external partners
• Improving system reliability, performance, and security across production environments
• Contributing to engineering best practices across CI/CD, DevSecOps, and testing
• Supporting and mentoring engineers as the team continues to scale

What We’re Looking For

• 5+ years of professional software engineering experience in a team environment
• Strong Python experience in production systems
• Experience designing and operating distributed systems at scale
• Hands‑on experience with public cloud platforms (AWS preferred)
• Familiarity with services such as object storage, message queues, managed compute, and serverless tooling
• Experience with Infrastructure as Code and automated deployment pipelines
• Exposure to data processing or ETL pipelines (batch or streaming)
• Experience with monitoring, logging, and observability in production systems
• Background in financial systems, trading, or market data is a plus but not required

Why This Role?

• Work on core financial infrastructure rather than surface-level features
• Tackle real‑time, data‑heavy engineering problems
• Strong engineering culture with emphasis on ownership and pragmatism
• Hybrid working model with flexibility built in
• Competitive compensation and comprehensive benefits
• Clear scope for technical growth and leadership

This role will require 3 days a week onsite in Austin, with a salary in the range of $160,000 to $180,000 + bonus + benefits.
