The Senior Packet Core Engineer focuses on designing and maintaining core network elements for mobile data services, while the Network Operations Engineer handles overall network monitoring and support. Both roles require networking certifications and work within telecom or ISP environments, but their daily tasks differ in scope and specialization.

What are some common challenges faced by senior packet core engineers, and how can they be addressed?

Senior Packet Core Engineers often encounter challenges such as managing complex network integrations, ensuring high availability, and troubleshooting advanced issues in live mobile core networks. Staying updated with evolving technologies like 5G and virtualization can also be demanding. To address these challenges, engineers typically collaborate closely with cross-functional teams, participate in ongoing training, and implement robust monitoring tools to proactively identify and resolve potential issues. Strong problem-solving skills and continuous learning are essential for success in this dynamic role.

What is a senior packet core engineer?

A Senior Packet Core Engineer is a highly skilled telecommunications professional responsible for designing, implementing, and maintaining the packet core network infrastructure that supports mobile data services. Their role involves managing core network elements such as SGSN, GGSN, MME, and EPC nodes, ensuring reliable and efficient data transmission across 3G, 4G/LTE, and 5G networks. They also troubleshoot complex issues, optimize network performance, and may lead teams in deploying new technologies or upgrades. Senior Packet Core Engineers frequently collaborate with vendors, network architects, and other engineers to ensure seamless integration and high availability of services.

What are the key skills and qualifications needed to thrive as a senior packet core engineer?

To thrive as a Senior Packet Core Engineer, you need in-depth knowledge of mobile core network architecture (EPC, 4G/5G), strong troubleshooting abilities, and a degree in telecommunications or a related field. Proficiency with network management tools, packet analyzers (like Wireshark), and certifications such as Cisco CCNP or Nokia NRS are typically required.

Job description

This Core Engineer hire exists to build robust full-stack systems that integrate with complex legacy environments and support high-value supply chain operations. The ideal candidate is a highly motivated, fast-shipping engineer who thrives in ambiguous, fast-paced environments — a backend-leaning full-stack developer proficient in TypeScript, Svelte (or React/Next.js), and Postgres. Open to any seniority level, including new grads, provided they can architect systems independently and demonstrate end-to-end project ownership. Must be willing to work strictly on-site in San Francisco.

Details

  • Location: San Francisco, United States · On-site
  • Employment: Full-time
  • Seniority: Mid-Senior Level (open to strong new grads who can own systems end-to-end)
  • Core stack: TypeScript, Svelte, PostgreSQL, Python, React, Next.js
  • Visa & work authorization: US citizens or current visa holders preferred; sponsorship available (E2/O-1). Physical relocation to San Francisco strictly required.


About the company
Our client is a seed-stage startup building an AI-native platform to modernize defense, aerospace, and industrial supply chains. Backed by top-tier investors, with 7-figure ARR, the company is replacing legacy 1980s systems with autonomous operations.


What we're looking for

  • Proficiency in TypeScript or JavaScript and at least one modern frontend library (Svelte, React, Next.js)
  • Strong knowledge of SQL databases, specifically writing and optimizing complex queries (Postgres preferred)
  • A verifiable portfolio of shipped work (at least one full-stack project via GitHub repo, web app, or recorded demo)
  • US citizen, current visa holder, or eligible for E2/O-1 visa sponsorship


Nice to have

  • Experience architecting systems independently from scratch
  • Background in high-accountability, fast-paced startup environments (e.g., YC alumni)
  • Prior experience or demonstrated enthusiasm for defense, aerospace, or industrial supply chain domains
