Job description

Summary

Are you a Mobile Engineer who enjoys leading small teams, staying hands-on in the code, and helping build products and teams from the ground up?

As an Engineering Team Lead at Topstep, you’ll lead a growing team responsible for building and evolving our mobile trading platform using React Native. This is a hands‑on leadership role where you’ll spend roughly 50% of your time coding while also supporting, mentoring, and coordinating a team of mobile engineers.

You’ll help drive delivery for our mobile applications, establish strong engineering practices, and collaborate closely with product, design, and other engineering teams to create exceptional mobile experiences for traders. Initially, you’ll manage a team of four engineers, with the opportunity to help scale the mobile organization as mobile becomes an increasingly strategic investment for the company.

This role is ideal for someone who is transitioning from senior engineer to engineering leadership, or an early‑career manager who still loves building software and wants to grow their people leadership experience alongside a fast‑moving product team.

Key Responsibilities

• Lead and support a team of mobile engineers building React Native applications across iOS and Android.
• Remain deeply hands‑on in development, contributing directly to architecture, implementation, code reviews, debugging, and releases.
• Partner with product, design, and other engineering teams to deliver high‑quality mobile experiences aligned with business priorities.
• Help establish scalable mobile engineering practices including component patterns, testing strategies, release processes, and code quality standards.
• Own delivery execution for the mobile team, balancing speed, quality, and technical sustainability.
• Coach and mentor engineers through regular feedback, career development conversations, and technical guidance.
• Support hiring efforts and help grow the mobile engineering organization over time.
• Contribute to technical direction for React Native architecture, state management, API integration patterns, and application performance.
• Help create a strong engineering culture focused on collaboration, ownership, continuous improvement, and customer impact.
• Drive operational excellence around mobile releases, monitoring, crash reporting, and production support.
• Collaborate across teams to advocate for mobile‑first thinking and ensure backend/platform decisions support mobile scalability and performance.

Required Qualifications and Key Competencies

• 5+ years of professional software engineering experience with significant experience building production mobile applications.
• 1‑2 years of direct engineering management or team leadership experience.
• Strong hands‑on experience with React Native and modern mobile application development practices.
• Strong TypeScript and JavaScript fundamentals, including React patterns, hooks, component composition, and state management.
• Strong database fundamentals, including experience with PostgreSQL or SQL Server‑schema design, migrations, indexing, and query optimization.
• Experience shipping and maintaining applications in both the iOS App Store and Google Play Store.
• Experience integrating APIs using GraphQL, Apollo Client, REST, or similar technologies.
• Familiarity with mobile architecture concepts including navigation, state management, reusable components, and performance optimization.
• Experience with mobile testing strategies including unit, integration, and end‑to‑end testing.
• Understanding of mobile CI/CD workflows, release management, TestFlight, and Play Store deployment processes.
• Comfortable balancing technical leadership with people leadership responsibilities.
• Strong communication and collaboration skills with the ability to work effectively across engineering, product, and design teams.
• Ability to provide clear technical direction while remaining pragmatic and delivery‑focused.
• Experience participating in hiring, interviewing, onboarding, or team growth initiatives.

Preferred Qualifications

• Experience building fintech, trading, or real‑time data applications.
• Familiarity with WebSockets, GraphQL subscriptions, or other real‑time communication technologies.
• Experience with native iOS (Swift) or Android (Kotlin) development.
• Familiarity with crash reporting and observability tooling such as Sentry or Crashlytics.
• Experience with mobile analytics, feature flags, or remote configuration platforms.
• Exposure to mobile security best practices including secure authentication and token storage.
• Experience building reusable component libraries or contributing to design systems.
• Prior experience helping scale engineering teams or processes in a high‑growth environment.

• 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.

• 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

• $160,000 - $190,000.
• 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.
