Senior Staff Software Developer, Core Infrastructure

Join us in building the future of finance.

Our mission is to democratize finance for all. An estimated $124 trillion of assets will be inherited by younger generations in the next two decades. The largest transfer of wealth in human history. If you’re ready to be at the epicenter of this historic cultural and financial shift, keep reading.

About the team + role

We are building an elite team, applying frontier technologies to the world's biggest financial problems. We're looking for bold thinkers. Sharp problem-solvers. Builders who are wired to make an impact. Robinhood isn't a place for complacency, it's where ambitious people do the best work of their careers. We're a high-performing, fast-moving team with ethics at the center of everything we do. Expectations are high, and so are the rewards.

The Core Infrastructure team's mission is to build and evolve the foundational platform that every Robinhood engineering team builds on — owning the systems, primitives, and developer-facing abstractions that power 24/7 trading, crypto, and global expansion. We treat infrastructure as a product: reliable, fast to provision, and invisible to the teams above it.

As a Senior Staff Software Developer on Core Infrastructure, 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 not an operations role — it's a once-in-a-platform-lifecycle opportunity to redesign the foundation before complexity becomes permanent!

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

At Robinhood, we believe in the power of in-person work to accelerate progress, spark innovation, and strengthen community. Our office experience is intentional, energizing, and designed to fully support high-performing teams.

• Own service mesh architecture end-to-end — standardize and evolve Robinhood's Istio and Envoy deployment, eliminate deprecated communication patterns, and build the networking foundation for multi-region operation

• Drive Kubernetes compute platform evolution — define 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 — transform 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 — 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 — produce architecture proposals, lead design reviews, and drive cross-functional alignment on infrastructure decisions that affect every engineering organization at Robinhood

What you bring

• Deep, hands-on expertise with Kubernetes internals — 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; experience debugging at the control-plane/data-plane boundary

• HTTP/2 and gRPC wire-level knowledge — connection management, flow control, stream multiplexing, and observability

• Terraform at architectural scale — module design patterns, provider
