Tech Lead, Mobile Core Network Engineering

Experienced in SRE or Infrastructure Leadership: 7+ years in SRE, infrastructure engineering, or network engineering, with a track record of operating complex, high-availability platforms at scale. Strong Networking Fundamentals: Deep understanding of IP networking, routing, tunneling protocols, DNS, DPI. You can reason about packet flows across distributed systems and debug from the wire up. Vendor Management Experience: You've managed vendor or managed-service relationships for critical infrastructure. You know how to review their work, hold them accountable, and coordinate across vendor, operations, and product teams without micromanaging. AI-First Mindset: You actively use AI tools to accelerate incident triage, anomaly detection, and root cause analysis, and continuously evolve how you apply them to raise the bar on operational excellence. Technical Leadership & Ownership: You've provided technical direction and mentorship to other engineers, see problems before they're escalated, and drive them to resolution. You enjoy technical leadership and want to grow into leading a team. Incident Management & Observability: Comfortable handling production incidents, analyzing root causes, and implementing long-term fixes. Hands-on experience with observability platforms like Datadog, Prometheus, Grafana, or the ELK stack. AWS Infrastructure: Experience with AWS (EC2, EKS, VPC networking) or equivalent cloud platform. Comfortable Operating in Ambiguity: You don't need to have all the answers on day one, but you know how to find them. You're motivated to learn new technical domains and apply that learning quickly. You’ll stand out if you have: Experience with mobile core network operations (LTE/5G EPC/NSA)—hands-on experience with HSS, PGW/SGW, PCRF, or similar network functions Understanding of 3GPP standards, Diameter, GTP, or mobile packet core architecture Experience at an MVNO or with carrier/MVNO-specific network challenges Familiarity with IMS or VoLTE deployments, SIP, SMPP, SMTP
