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.
• Strong database fundamentals with PostgreSQL or SQL Server, including schema design, migrations, indexing, and query optimization.
• A production mindset and bias toward action, embracing metrics, logging, tracing, on-call participation, and end-to-end ownership of delivery.
• Excellent communication skills, with the ability to explain complex technical concepts to a range of audiences and work well with Product, Design, and QA.

Preferred Qualifications

• Background in financial technology or highly regulated spaces where precision, traceability, and regulatory standards drive engineering decisions.
• Practical expertise with payment gateways, billing infrastructures, or authentication and user identity services.
• Hands-on familiarity with AWS services, container orchestration (Docker, Kubernetes), and modern deployment pipelines using Argo CD or GitHub Actions.
• Proven capability leveraging AI developer tooling effectively while upholding rigorous standards for code health and maintainability.
• Track record of delivering high-scale, end-user applications with a sharp focus on intuitive product design.

Company Culture & Perks

• Topstep is an engaging working environment which ranges from fully remote to hybrid. We foster a culture of collaboration with cameras on during meetings and a robust Slack environment for communication. 
• Seven Company-paid Holidays and generous Family Leave. Paid time off is front-loaded. 
• Competitive 401(k) matching, health, dental, and vision insurance is offered for full time employees.
• Vacations are encouraged with a bonus for taking 5 consecutive days. Employee referrals are bonused. Topstep offers a food and groceries budget and contributes towards health and wellness.

New Hire Base Salary Range

• $155,000 - $193,000k annually.
• Bonus: This position is eligible for a performance-based bonus as provided by the plan terms and governing documents.
• The compensation offered will take into account internal compensation structure and may vary depending on the candidate's geographic region, job-related knowledge, skills, and experience among other factors.
