Infrastructure Manager

About IPinfo

IPinfo provides IP geolocation and network data trusted by developers and enterprises worldwide, powering everything from fraud prevention to content personalization. We run infrastructure that serves massive query volumes with strict latency and uptime requirements, reliability isn't a nice-to-have here, it's the product.

About The Role

We're looking for a * hands-on Infrastructure Manager * to lead our infra team. This isn't a purely strategic or people-management role, we need someone who still enjoys being in the weeds: debugging a noisy alert at 2 AM, reviewing a Terraform PR, or getting on a call mid-incident to help mitigate a DDoS attack in real time.

You'll own the reliability, scalability, and security of infrastructure that handles high-volume, latency-sensitive traffic at global scale, while growing and mentoring a small team of engineers.

What You'll Do

- Lead and mentor the infrastructure team while remaining directly involved in architecture, coding, and operations
- Own the design and evolution of infrastructure serving high-throughput, low-latency workloads at scale
- Lead DDoS mitigation strategy and incident response from architecture-level protections to live handling of active attacks
- Drive capacity planning, cost optimization, and performance tuning across the stack
- Improve observability, alerting, and on-call practices to reduce time-to-detect and time-to-resolve
- Own infrastructure security posture in collaboration with the security function
- Balance team growth and process maturity with the need to keep shipping and firefighting when it matters
- Participate in on-call rotation

What We're Looking For

- 8+ years in infrastructure/SRE/platform engineering roles, including significant hands-on scaling experience
- 5+ years of experience managing or leading an infrastructure/SRE team, while staying technically hands-on
- Proven experience defending large-scale services against DDoS attacks (mitigation strategies, tooling, live incident response not just theoretical knowledge)
- Deep experience with cloud infrastructure (AWS/GCP/Azure), networking fundamentals (BGP, DNS, CDN, load balancing), and infrastructure-as-code (Terraform, Ansible, etc.)
- Strong Linux systems knowledge and experience operating distributed, high-availability systems at scale
- Track record of leading incident response for critical, customer-facing infrastructure
- Comfortable balancing technical depth with people leadership as this role is genuinely both
- Excellent communication skills; able to explain technical trade-offs to both engineers and leadership

Nice to Have

- Experience with high-volume API infrastructure or data-heavy platforms
- Familiarity with Anycast networking and edge/CDN architectures
- Background in a company that has weathered significant/sustained DDoS campaigns
- Contributions to open-source infra tooling
