What are some common challenges faced when working as an LTE Protocol Stack Engineer?

As an LTE Protocol Stack Engineer, you may encounter challenges such as debugging complex signaling issues across different protocol layers, ensuring interoperability with various network equipment, and optimizing performance under real-time constraints. The role often involves analyzing logs, troubleshooting integration problems, and staying updated with evolving 3GPP standards. Collaborating closely with cross-functional teams like hardware, RF, and application developers is essential for end-to-end feature validation and issue resolution.

What is the difference between Lte Protocol Stack vs Radio Network Engineer?

AspectLte Protocol StackRadio Network Engineer
Primary FocusDesign and development of LTE protocol layers and standardsDeployment, optimization, and maintenance of radio networks
Required SkillsNetworking protocols, LTE standards, software developmentRadio frequency, signal analysis, network troubleshooting
Work EnvironmentResearch labs, telecom companies, software firmsCell sites, network operation centers, fieldwork
CertificationsLTE certifications, networking certifications (e.g., Cisco, Nokia)RF certifications, Cisco, or vendor-specific certifications

While the Lte Protocol Stack focuses on the technical standards and software development of LTE networks, the Radio Network Engineer handles the practical deployment and optimization of radio infrastructure. Both roles require telecom knowledge but differ in their core responsibilities and work environments.

What are the key skills and qualifications needed to thrive as an LTE Protocol Stack Engineer, and why are they important?

To thrive as an LTE Protocol Stack Engineer, you need a strong background in wireless communications, embedded systems, and a solid understanding of 3GPP LTE protocol specifications, typically supported by a degree in Electrical Engineering, Computer Science, or a related field. Experience with C/C++ programming, real-time operating systems (RTOS), and familiarity with protocol analyzers and debugging tools are essential technical requirements. Analytical thinking, strong problem-solving abilities, and effective teamwork are key soft skills that help in addressing complex protocol issues and working collaboratively in cross-functional teams. These skills and qualifications ensure robust development, troubleshooting, and optimization of LTE protocol stacks, which are critical for the performance and reliability of modern wireless communication systems.

What is the LTE protocol stack?

The LTE protocol stack is a set of layered protocols used in Long Term Evolution (LTE) mobile networks to manage communication between mobile devices and the network. It includes layers such as the Physical Layer (PHY), Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC). Each layer serves a specific function, such as data transmission, error correction, and managing signaling. Understanding the LTE protocol stack is essential for developing, testing, and troubleshooting mobile network solutions.

Job description

Headquartered in Birmingham, Alabama, Moultrie (www.moultrie.com) is the leader in game feeders and cellular camera innovation, building products used by hunters, property owners, and others for real-time remote monitoring.

We take pride in developing deep user understanding, obsessing about the details, and going the extra mile to show our users we love them. Moultrie is customer-driven – hardware, software, marketing, and customer success teams collaborate to deliver a quality user experience.

We are guided by the following principles: Customer Obsession.; Excellence is the Standard.; Bias for Action.; Act Boldly.; Deliver Results.; Hire and Develop the Best.; Be Curious and Learn.; Win as a Team

Job Summary

At Moultrie, connectivity isn't a feature — it's the foundation of everything we build. As a Sr. Cellular Connectivity Engineer, you'll own the end-to-end communication stack between our field-deployed cameras and cloud infrastructure, making sure our devices stay connected reliably and efficiently in the real world. 

You'll dig deep into carrier protocols, diagnose issues at the modem and radio layer, and work closely with firmware, application, and cloud teams to optimize how our devices communicate. If you're someone who thrives on complex connectivity problems and cares about getting it right, this is the role for you.

Job Responsibilities

Diagnostics & Protocol Analysis

  • Analyze and interpret carrier-level protocol behavior to identify and resolve connectivity issues at the modem and radio layer.
  • Capture and dissect network traffic to diagnose packet-level anomalies, protocol misconfigurations, and communication inefficiencies between cameras and backend servers.
  • Trace issues across the full stack — from the device modem through the carrier core network to the application server — and isolate where things are breaking down.

Connectivity Optimization

  • Monitor and evaluate the full communication path between edge camera devices and cloud infrastructure, ensuring protocol conformance, message integrity, and session stability.
  • Design, evaluate, and tune retry policies and reconnection logic to maximize connection reliability while minimizing unnecessary radio activity and preserving battery life.
  • Investigate and resolve bottlenecks related to carrier network behavior and internet and application-layer inefficiencies.

Protocol & Stack Work

  • Work with application and firmware teams to optimize MQTT broker and client configurations.
  • Analyze TCP/IP stack behavior in constrained cellular environments.
  • Collaborate with cloud and backend engineers.

Standards & Documentation

  • Contribute to defining and enforcing communication design standards for new camera hardware and firmware revisions.
  • Produce detailed diagnostic reports, root cause analyses, and optimization recommendations for internal engineering teams and external stakeholders.
Job Requirements

What You Bring

  • Hands-on experience with modem-level diagnostics and log capture and analysis.
  • Proficiency with deep packet inspection and protocol analysis across multiple layers.
  • Strong understanding of cellular carrier protocols.
  • Familiarity with carrier-specific behaviors as they relate to IoT device connectivity.
  • Solid understanding of TCP/IP, including IP addressing, routing, flow control, congestion avoidance, and connection lifecycle management.
  • Experience working with MQTT in IoT deployments.
  • Practical experience analyzing and debugging client-server communication flows for IoT or embedded devices.
  • Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, Telecommunications, or a related field — or equivalent hands-on experience.
  • 5+ years of deep LTE-M/NB-IoT experience.

Bonus Points

  • Experience with LTE-M or NB-IoT deployments in commercial IoT products.
  • Hands-on experience with Microsoft Azure IoT services.
  • Familiarity with FOTA update protocols and their impact on connectivity resources.
  • Experience with embedded Linux or RTOS environments in cellular-connected devices.
  • Background in camera systems, surveillance technology, or field-deployed IoT hardware.
  • Scripting or automation experience.
  • Knowledge of 3GPP specifications relevant to IoT device behavior.
Essential Job Function

Why Moultrie

Our cameras are in the field — on fence posts, in tree stands, deep in the woods — and they need to work. The connectivity problems you'll solve here are real, the stakes are high, and the impact shows up directly in the experience of hundreds of thousands of users. You'll have the autonomy to dig in, the support of a strong engineering team, and the satisfaction of knowing your work makes Moultrie products better for the people who depend on them.
