Senior Staff Software Developer, Core Infrastructure

As a Senior Staff Software Developer on the Core Infrastructure team at Robinhood, you will own the architectural evolution of three deeply interconnected domains: service mesh and connectivity, compute platform, and infrastructure provisioning. Your decisions will directly shape engineering velocity, operational reliability, and Robinhood's ability to expand to new regions and markets. This is a once-in-a-platform-lifecycle opportunity to redesign the foundation before complexity becomes permanent.

This role is based in the Toronto, ON office, with in-person attendance expected at least 3 days per week.

What you'll do

• Own service mesh architecture end-to-end by standardizing and evolving Robinhood's Istio and Envoy deployment, eliminating deprecated communication patterns, and building the networking foundation for multi-region operation
• Drive Kubernetes compute platform evolution by defining the long-term direction for cluster lifecycle, scheduling strategy, control plane architecture, and multi-region resiliency across Robinhood's entire compute fleet
• Redesign infrastructure provisioning by transforming Terraform from a collection of ad-hoc configurations into a scalable, self-service platform capability that enables rapid region provisioning and developer autonomy
• Operate with source-level depth to diagnose and resolve issues at the Kubernetes API machinery, etcd, Envoy xDS, and Terraform provider layer, and contribute upstream where it serves the platform
• Define technical direction across teams by producing architecture proposals, leading design reviews, and driving cross-functional alignment on infrastructure decisions that affect every engineering organization at Robinhood

What you bring

• Deep, hands-on expertise with Kubernetes internals, including the API server, controller reconciliation, etcd watch propagation, scheduler mechanics, and admission control
• Deep working knowledge of Istio and/or Envoy at the source code level, including the xDS API as a protocol, and experience debugging at the control-plane/data-plane boundary
• HTTP/2 and gRPC wire-level knowledge, including connection management, flow control, stream multiplexing, and observability
• Terraform at architectural scale, including module design patterns, provider internals, remote state management, and multi-region provisioning
• Production-grade Go or Python for infrastructure tooling, with strong fundamentals in writing well-structured, tested, operationally sound code
• Proven ability to drive cross-functional architectural change across large or complex engineering organizations by influencing without authority and shipping durable decisions

What we offer

• Base pay of $234,000 to $275,000 CAD, plus bonus opportunities and equity
• Performance-driven compensation with multipliers for outsized impact
• Top-tier benefits including supplemental health insurance, ancillary insurance, and mental health support programs
• Access to leading AI tools on the market and continuous AI skill-building for every employee
• Lifestyle wallet, a highly flexible employer-paid benefits spending account for wellness, childcare, learning, and more
• Time off including company holidays, paid time off, sick time, paid volunteer time off, and parental leave
• Exceptional office experience with catered meals, events, and comfortable workspaces
• Monthly commuter stipend to help offset in-office commuting costs
