Software Engineer - Pre-trade analytics, risk, portfolio optimization

About the role

As a Senior Software Engineer, you will play a foundational role in building our Alpha Platform - a modern, AI-driven system for pre-trade analytics, risk, hedging, portfolio optimization, and customized client exposure management. You'll join a team of passionate, collaborative engineers tackling non-trivial problems that demand careful trade-off analysis, clean system design, and efficient implementation. You will work across the full stack, from data ingestion and processing pipelines to AI-driven analytics and client-facing API layers, on a high-SLA financial platform built to the highest engineering standards. You will help evolve our technical standards and best practices, and promote a culture of excellence. The Team: Our team is composed of highly talented, motivated engineers passionate about pushing the boundaries of financial technology. Together, we are building a platform at the forefront of technological innovation that will serve institutional clients globally. As a member of our team, you will work with cutting-edge technologies, collaborate with colleagues from diverse backgrounds, and make a meaningful impact on the financial industry. We value creativity, innovation, and a strong work ethic, and are committed to giving every team member the support and resources they need to succeed.

Requirements

• You are fluent in AI-assisted development workflows, leveraging tools such as Claude Code to accelerate delivery, and are comfortable with Spec-Driven Development (SDD).
• You take end-to-end ownership of problems. Given a complex or ambiguous requirement, you can independently define the approach, navigate trade-offs, and drive a solution from initial design and coding through production delivery without hand-holding at each step.
• You can clearly articulate the nuances of system design and architectural paradigms to both engineers and non-technical stakeholders.
• You prioritize end-user experience, and it shows in your API design, functionality, and performance.
• You have a strong command of design patterns, data structures, and algorithms.
• You will help mentor team members, define engineering standards, and drive a system design approach to building new services.
• Preferred, but not required: hands-on experience with our platform stack - gRPC, PostgreSQL, Redis, Docker, Gradle, uv, AWS, and Kubernetes. Readiness to learn is required.
• You are comfortable working in, or learning, domains such as financial risk or pre-trade analytics. A strong plus: exposure to finance with an understanding of instruments and concepts such as swaps, custom baskets, the trade lifecycle, performance calculations and attribution, and factor models.
