Software Engineer

**Summary

**As a Senior Software Engineer on Topstep's TRM Engineering team, you'll build the products funded traders and our internal teams use every day: the trader-facing web experience, account and onboarding flows, payments and payouts, and the internal tooling the business runs on. We help new and experienced traders through training, insights into their trading patterns, and a smooth path to their payouts, and the systems behind that experience need to be reliable, secure, and easy to change as we grow.

You'll work primarily in TypeScript across Node.js and React, building cloud-native applications on AWS. Beyond shipping features, you'll own work end to end from design through production, raise the bar on code quality and engineering patterns across the team, and help make sure our systems scale safely as usage and complexity increase.

This role is ideal for an engineer who wants real ownership of systems that directly shape the trader experience, and who cares as much about how software runs in production as how it's written.

Key Responsibilities

• Design, build, and operate full stack features end to end, from technical design through deployment and production support, with an emphasis on reliability, safe deployments, and operational simplicity.
• Partner with Product and Design during discovery to shape scope, surface technical trade-offs early, and provide credible estimates.
• Write technical designs for significant work and guide architecture decisions within your area, in partnership with your Engineering Manager and fellow senior engineers.
• Build automated testing, observability, and operational ownership into every stage of delivery.
• Raise the team's engineering bar through thoughtful code review, mentoring, and contributing to shared standards and patterns.
• Proactively identify and resolve issues across the stack, keeping our systems stable, performant, and ready to grow.
• Participate in the on-call rotation and incident follow-through, turning production issues into lasting fixes.
• Use AI-assisted development tools effectively and responsibly, within Topstep's standards for AI-built software.

Required Qualifications and Key Competencies

• 5+ years of experience building and operating production-grade systems with user-facing APIs, with demonstrated impact on scalability and reliability.
• Strong full stack foundation: backend development in TypeScript and Node.js with solid API design (REST, GraphQL), and modern frontend development in React and Next.js.
• Experience designing and operating distributed systems, including event-driven architectures, message queues, eventual consistency, and concurrency and race-condition handling, with a strong focus on performance, security, and maintainability.
