Topstep is looking to modernize its platform and improve the trader experience by establishing architectural patterns and raising the technical bar for its engineering teams.
Requirements
- Strong full-stack foundation with expertise in both backend API design (GraphQL, REST) and modern frontend development (React, Next.js, TypeScript)
- Deep PostgreSQL knowledge including schema design, query optimization, indexing strategies, and understanding of transaction isolation and consistency patterns
- Proven GraphQL expertise designing schemas, implementing resolvers, optimizing queries (N+1 problems, data loader patterns), and building maintainable API layers
- Modern frontend mastery with Next.js, React, TypeScript, and Tailwind CSS, including Server Components, hydration patterns, and performance optimization
- Production ownership mindset with experience building observable, testable, and maintainable systems including instrumentation, error handling, and debugging distributed issues
- Solid understanding of distributed systems including event-driven architectures, message queues, eventual consistency, and handling race conditions
- Familiarity with event-driven architectures using systems like NATS, Kafka, or similar message brokers
Responsibilities
- Set technical direction for full-stack architecture across the engineering organization, influencing how we design APIs, structure frontends, and ensure system reliability
- Own end-to-end feature development from Postgres schema design through GraphQL APIs to Next.js UI, ensuring seamless integration and optimal performance
- Establish engineering patterns for GraphQL schema design, React component architecture, state management, and API/UI coupling that other teams can adopt
- Drive architectural improvements during our modernization initiative, helping transition from monolithic systems to event-driven microservices while maintaining feature velocity
- Lead technical initiatives that materially improve developer experience, system performance, or code quality across the organization
- Champion quality and reliability by embedding testing, monitoring, and operational thinking into every feature you ship
- Mentor engineers across teams on full-stack best practices, architectural thinking, and production ownership
Other
- 7+ years of professional experience building production web applications, with demonstrated impact establishing patterns and practices that scaled across multiple teams
- Track record of technical leadership through RFCs, architectural documentation, code reviews, and establishing engineering standards
- Excellent communication skills with the ability to explain complex technical trade-offs to varied audiences and build consensus across teams
- Comfortable making pragmatic decisions balancing long-term architectural vision with immediate business needs and feature delivery
- At this time immigration sponsorship is not available for this position (including H-1B, STEM OPT training plans, etc.).
