This isn't just about shipping features - you'll shape architectural decisions, establish engineering standards, and ensure our platform scales reliably as we grow. You'll own your systems end-to-end, from initial design through production operations.\nThis role is ideal for someone who combines deep technical expertise with the judgment to navigate ambiguity and complexity. You'll balance robust, maintainable systems against the reality of evolving business requirements, contribute to technical strategy, mentor other engineers, and help define what engineering excellence means at Topstep.\nKey Responsibilities\nDesign and build services and APIs that power core trading platform capabilities.\nOwn initiatives end-to-end, from technical design through production deployment, monitoring, and iteration.\nCollaborate with product and design to translate user needs into scalable, maintainable technical solutions.\nContribute to system architecture decisions, establishing patterns and practices that other teams can follow.\nWrite clean, well-tested code with strong focus on reliability, performance, and operational excellence.\nParticipate in on-call rotations, respond to incidents, and drive continuous improvement of system reliability.\nBuild and maintain observability into your systems through metrics, logging, and distributed tracing.\nOccasionally work across the stack, contributing to the React/TypeScript frontend as features require.\nMentor engineers through code reviews, pairing sessions, and sharing knowledge about system design and best practices.\nBalance technical debt against feature delivery, making thoughtful trade-offs based on business priorities and technical constraints.\nStrengthen engineering culture through documentation, tooling improvements, and process refinements.\nRequired Qualifications and Key Competencies\n8 + years of software engineering experience building and shipping production systems at scale.\nDeep proficiency in C# and the .NET ecosystem, with a track record of designing production services used across multiple teams.\nExperience with React, TypeScript, or other modern frontend frameworks.\nExperience designing service boundaries and API versioning in a microservices or modular architecture.\nExtensive experience building distributed, high-availability systems, including asynchronous, event-driven communication between services (e.g., message queues, pub/sub, or streaming).\nDeep database experience with PostgreSQL or SQL Server, including schema design, query optimization, and transactional behavior.\nExperience with observability tools and distributed tracing in production environments.\nProven track record of owning production systems, including debugging and incident response.\nExperience with container technologies (Docker) and cloud platforms (AWS)\nStrong testing mindset with practical experience across unit, integration, and system testing.\nProven capability leveraging AI developer tooling effectively while upholding rigorous standards for code health and maintainability.\nExcellent problem-solving skills, with the ability to debug complex issues across multiple systems.\nDemonstrated ability to build consensus and drive complex technical initiatives across teams without relying on direct authority.\nExcellent communication skills, including the ability to explain technical trade-offs to both engineering and product stakeholders.\nPreferred\nKubernetes experience (EKS or equivalent), Helm, or GitOps (ArgoCD) tooling.\nExperience with real-time client comms (SignalR/WebSockets).\nBackground in high-throughput, low-latency systems, including performance tuning across multiple services.\nIncident leadership (RCA, remediation follow-ups).\nPrevious work in financial services, fintech, or other compliance-regulated environments.\nUnderstanding of trading systems, market data, or brokerage operations.\nCompany Culture & Perks \nTopstep is an engaging working environment that ranges from fully remote to hybrid.
