Solution Architect

Join our Team

About this opportunity

We are looking for a Solution Architect (Heuristics, DPI & SACC) to lead the architecture, development, and modernization of heuristic-driven and policy-based network intelligence solutions for service classification within Packet Core domains. This role focuses on designing end-to-end Heuristics and Deep Packet Inspection (DPI) frameworks, enabling accurate service identification, QoS optimization, and traffic monetization for our telecom partners.
You will work closely with engineering, R&D, and customer operations teams to translate business needs into scalable solutions that enhance Ericsson’s adaptive, data-driven network intelligence capabilities.

What you will do

• 
  Lead the design and delivery of heuristic-based and DPI solutions for 4G/5G Packet Core, including PGW, PCC, PCG, and CUPs.
• Create and maintain high-level (HLD) and low-level (LLD) designs for heuristic and DPI use cases.
• Develop and refine heuristic protocol signatures for application and service identification.
• Integrate solutions across IN, PCRF, and EPG systems to ensure real-time service delivery.
• Implement QoS, SPI, and Header Enrichment features to enable service differentiation and charging optimization.
• Collaborate with R&D and business units to transform operator requirements into deployable solutions.
• Troubleshoot complex network traces to identify data misclassification and prevent fraud.
• Drive modernization of heuristic and policy engines, advancing from static to ML-assisted models.
• Validate solution performance through KPI tracking, SLA compliance, and operational benchmarks.
• Act as a customer-facing technical lead for Proof of Concept (PoC) and live deployments.
• Mentor technical teams to ensure ongoing service optimization and delivery excellence.

The skills you bring

• 
  12+ years of experience in Telecom Core Network architecture with expertise in EPC, 5G Core, PCRF, DPI, and SACC.
• Proven experience delivering large-scale heuristic or service identification projects for telecom operators.
• Deep understanding of interfaces such as Gx, Gy, Ny, and Nchf and their relevance to policy, charging, and enforcement.
• Strong hands-on experience with Ericsson Packet Core (EPG2/3, PCC, PCG, CUPs) and QoS frameworks.
• Skilled in traffic classification, heuristic signature tuning, and DPI optimization.
• Experience in project planning, stakeholder management, and cross-functional coordination.
• Excellent communication, analytical, and problem-solving skills with the ability to translate business goals into architecture roadmaps.

Preferred certifications

• 
  Ericsson Certified EPC Associate
• 5G Core Concepts & vEPC Hands-On (Ericsson)

Behavioral attributes

• 
  Innovative Problem Solver: Translates complex network behavior into accurate heuristic logic.
• Customer-Focused Leader: Serves as the single point of contact for heuristic and service classification solutions.
• Strategic Collaborator: Aligns business and technology to achieve measurable network improvements.
• Continuous Improver: Constantly evolves heuristic models to improve speed, accuracy, and efficiency.

Key success indicators

• 
  Enhanced service detection accuracy across network layers.
• Reduced downtime through optimized heuristic frameworks.
• Improved QoS, latency, and throughput KPIs across operator networks.
• Increased automation and modernization of network intelligence systems.
