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 Custody Services team is responsible for managing our crypto infrastructure, digital asset custody providers, and the various integrations we maintain with third-parties — from wallet management to crypto infrastructure management! The team is also responsible for processing crypto transactions, as well as products like staking, lending, and travel rule compliance. We currently safeguard billions in assets under custody for millions of customers.

As a Senior Backend Engineer on this team, you'll work on the infrastructure behind crypto processing, wallet and key management workflows, and our integrations with third-party custodians. Most of what you'll build sits at the boundary between infrastructure and security.

This role is based in our London, UK office(s), 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.

Requires participation in an on-call rotation to support business needs.

What you’ll do

• Build and run the AWS infrastructure behind custody, key management, and blockchain node operations.
• Automate infrastructure and configuration management (Ansible, Terraform, or similar) so the team spends less time on manual operations.
• Run our blockchain nodes across the networks we support, and keep them healthy and available.
• Write and maintain services in Python for infrastructure management and wallet operations.
• Own the integrations with third-party custodians.
• Build out Kubernetes and Docker deployments as we containerize more of the custody stack.
• Set up monitoring and alerting (Prometheus, Grafana, or equivalent) so we know about problems before customers do.
• Apply security controls and standards throughout — access control, key management, incident response.
• Provide on-call support, responding to and resolving production issues to keep custody systems reliable and available.

What you bring

• Senior-level experience running cloud infrastructure (AWS) in production.
• Experience managing blockchain nodes in production.
• Hands-on experience with Ansible, Terraform, or similar configuration management and Infrastructure as Code tooling.
• Experience running containerized workloads on Kubernetes and Docker.
• Solid Python and/or Go skills, with real production experience.
• A strong security focus — you’ve worked on systems where key management and access control are critical.
• Experience with Prometheus, Grafana, or an equivalent monitoring stack.
• Experience integrating with third-party custodians like BitGo or Fireblocks — this is a key differentiator for this role.

What we offer

• Challenging, high-impact work to grow your career
• Performance driven compensation with multipliers for outsized impact, bonus programs, and equity ownership
• Top tier benefits to fuel your work, including supplemental health insurance, ancillary insurance, and mental health support programs
