Resident Engineer at APN Software Services Inc

Role Objective We are seeking a highly skilled and strategic Resident Engineer to embed with our clients engineering team for a critical 6-month engagement. The primary objective of this role is to accelerate the troubleshooting of complex network issues using AGILITY product. You will serve as the first line of defense in distinguishing whether performance degradations originate from the RAN Core or User Plane drastically reducing Mean Time to Resolution (MTTR). Beyond technical execution you will act as a Trusted Advisor and ambassador. You will leverage your proximity to the client to understand their pain points build custom automations (Python/Bash) to bridge gaps and identify new opportunities where portfolio can drive further value. Key Responsibilities 1. Advanced Troubleshooting & Root Cause Analysis Domain Isolation: Utilize AGILITY tool to rapidly analyze end-to-end call flows and packet captures (PCAP) to determine if issues are rooted in the Radio Access Network (RF conditions handovers) Core Network (signaling bearer setup) or User Plane (transport throughput). Protocol Analysis: Deep dive into signaling protocols (S1AP NGAP GTP-C/U SIP RRC) to pinpoint failure causes such as connection drops handover failures or latency spikes. Support & Collaboration: Work side-by-side with the clients RAN testing teams and OEM vendors to provide data-backed evidence for defect ownership effectively ending "blame game" cycles between vendors. 2. Automation & Scripting Workflow Automation: Identify repetitive manual testing or log collection tasks and create scripts (e.g. using Python and Bash) to automate them integrating these flows into the AGILITY platform where possible. Custom Tooling: Develop "glue code" to parse complex log files or interface with client OSS/BSS APIs enhancing the team's ability to visualize network health. Innovation: Proactively suggest new methods for automated log parsing and signature detection to improve the AGILITY tools AI model accuracy over time. 3. Trusted Advisor & Business Growth Reailize 2025. All Rights Reserved. Page 2 1 Client Advocacy: Build strong trust-based relationships with client stakeholders (managers lead engineers) by demonstrating deep technical expertise and reliability. Opportunity Identification: Actively listen to client challenges beyond the immediate scope of work. Identify gaps in their current toolset or processes where other solutions or expanded AGILITY use cases could add value. Adoption Driver: Ensure the client team is fully comfortable with the AGILITY tool; conduct informal training sessions and "over-the-shoulder" coaching to drive product stickiness and adoption. Required Technical Qualifications Network Domain Knowledge: Strong understanding of End-to-End (E2E) network flows in 4G LTE and 5G NR. Ideally deep understand of both RAN and Core networks at least one of them is a must. Protocol Expertise: Proficiency in analyzing: o 5G/4G Interfaces: S1-MME S1-U N1 N2 N3. o Protocols: SIP (VoLTE/VoNR) RTP GTP TCP/IP basics. Tools: Expert-level skills in Wireshark or similar packet analysis tools. Familiarity with network monitoring/OSS tools. Scripting: Demonstrated ability to write scripts for automation and data manipulation using Python (pandas requests paramiko) and Bash/Shell. Soft Skills & Core Competencies "Trusted Advisor" Mindset: Ability to communicate complex technical findings to non-technical stakeholders in a way that builds confidence and authority. Sales Acumen: An entrepreneurial spirit with the ability to "listen for business" - identifying up- sell opportunities without being pushy. Diplomacy: Experience working in multi-vendor environments capable of navigating political sensitivities while remaining objective and data-driven. Autonomy: Self-starter who can define their own daily agenda and drive value without constant supervision.
