Who Are We?

RZR is an AI-native advertising platform built for the next era of performance marketing. We operate at the intersection of machine learning, programmatic media, and full-funnel mobile growth, powering campaigns for some of the world's most ambitious advertisers. Our platform is purpose-built to deliver outcomes at scale, not just impressions.

We are a team of builders, operators, and technologists who believe the advertising industry is overdue for a fundamental rethink. We move fast, operate with a high degree of ownership, and hold ourselves to an exceptionally high standard of craft.

RZR is scaling aggressively with an active M&A pipeline and a platform vision that puts us on a path to becoming an industry leader. This is a rare opportunity to join a company at an inflection point and help shape what it becomes.

Role Overview

RZR runs its own metal — four owned-and-operated data centers across Santa Clara, Ashburn, Amsterdam, and Hong Kong, housing approximately 1,300 servers and 1.15MW of capacity, placed next to the major ad exchanges, serving 5–6M+ bid requests per second at ~20ms. This infrastructure is our competitive moat, not a cost center.

As Manager, Infrastructure, you will own day-to-day and quarter-to-quarter operation of that entire footprint: the team, hardware lifecycle, capacity planning, incident response, and vendor relationships. You will take over these functions directly from the Head of Cybersecurity & Infrastructure, freeing him to focus on security and multi-entity IT.

This is a hands-on manager role. There is no "scale up" button here — latency, packets-per-second, and procurement lead times are the job. The right person combines deep bare-metal operational instincts with the leadership presence to run a distributed, experienced global team from day one.

Key Responsibilities

Team Leadership & Operations

Manage and develop the InfraOps team across US and APAC time zones, including regional DC owners (SV/VA and NL/HK) and network engineering
Own the weekly DevOps check-in cadence, alert reviews, and 24/7 on-call coverage model
Drive P1/P2 incident response end to end — accountability for MTTR reduction, runbook coverage, and alert hygiene

Capacity Planning & Hardware Lifecycle

Own capacity planning and hardware lifecycle across all four data centers: Dell and Supermicro procurement through VARs, GPU expansion for on-prem ML training and inference, colo power and space management, and remote-hands logistics with Equinix and Digital Realty
Run the annual cloud-vs-colo evaluation alongside leadership, with full ownership of the recommendation

Technical Platform Oversight

Oversee the core infrastructure stack: Ubuntu/systemd fleet, FreeIPA, Ansible/Salt configuration management, MAAS provisioning, and Zabbix monitoring
Manage the spine-leaf Mellanox/NVIDIA network via Netris, including 100G Google peering and transit blend (Lumen/Cogent/Zayo)
Support the stateful data tier — Aerospike, Kafka, ClickHouse, Hadoop/HDFS — across capacity limits, evictions, migrations, and low-latency tuning

Vendor & Budget Management

Own colo and vendor relationships and budgets: Equinix and Digital Realty invoices, transit contracts, VAR procurement, and Netris licensing
Partner with the security/compliance function on SOC 2 Type 2 evidence, infrastructure hardening, and access reviews
Operate comfortably within a multi-entity environment (RZR/Skillz/Firy/Beamable shared IT) with comfort in M&A-flavored ambiguity

Required Skills and Experience

Must-Have

6–8 years in infrastructure or data center operations with 2+ years managing engineers — this role takes over a functioning global team on day one
Bare-metal and colo depth: capacity planning, hardware procurement (Dell/Supermicro), IBX/remote-hands workflows, and the physical logistics of running owned cages
Network fundamentals at scale: spine-leaf architecture, BGP/peering (100G-class), transit blends, and low-latency tuning (NIC/IRQ, packets-per-second thinking)
Deep Linux operations: systemd, netplan, FreeIPA/Chrony, Ansible and/or Salt, Zabbix, running fleets of hundreds-plus servers
Experience operating large stateful distributed systems — Aerospike, Cassandra, Scylla, Kafka, or ClickHouse — under sub-50ms latency budgets and hard capacity limits
Demonstrated P1/P2 incident ownership: on-call program management, postmortems, and alert hygiene discipline

Nice-to-Have

Hybrid cloud experience alongside owned metal: AWS (IAM, Route 53, GuardDuty, S3); Kubernetes exposure a plus
SOC 2 or compliance evidence experience; Okta and Vanta familiarity; security-minded infrastructure approach
Experience in adtech, RTB, or other high-QPS, latency-sensitive environments
Netris or other SDN controller experience; MAAS provisioning familiarity

Work Setup

This is a remote role open to candidates based in the United States. The role requires periodic travel to our data center sites (Santa Clara, CA; Ashburn, VA; Amsterdam; Hong Kong) and SF HQ for operational reviews, team time, and site work.

Why Join RZR?

Own a genuinely rare infrastructure environment — four global owned-and-operated data centers, 5–6M+ QPS real-time bidding at ~20ms. This is infrastructure that is the company's competitive moat, running 4–10x faster bid response than cloud DSPs. You will not find this kind of physical infrastructure problem at most companies.
Full-stack ownership with no cloud-bill anxiety — real hardware decisions, GPU expansion for on-prem ML, and an annual cloud-vs-colo evaluation you will help drive. Zero marginal experimentation cost.
Inherit a functioning, experienced global team — regional DC owners with clear ownership and an established ops cadence. Build on it, not rescue it.
Direct line to leadership — reporting to the Head of Cybersecurity & Infrastructure with visibility to the SVP of Engineering. Your goals map straight to company OKRs.
Company momentum — RZR rebranded in March 2026 and is expanding aggressively across mobile, CTV, and influencer. Your infrastructure is what makes all of it possible.
