DNP3 Protocol Developer (C++)

Job Description

DNP3 Protocol Developer

Our client, a leader in automation technology, is looking for a highly skilled Software Developer with hands-on experience in developing the DNP3 (Distributed Network Protocol 3) communication protocol. This role is focused on low-level protocol implementation-not just using existing libraries, but actually coding the protocol itself.

The ideal candidate will bring deep technical expertise in DNP3, strong C++ programming skills, and a passion for building robust, scalable software for industrial control systems, SCADA networks, and critical infrastructure.

Responsibilities

Design, develop, and maintain software that implements the DNP3 protocol for industrial automation and utility applications.

Write clean, efficient, and well-documented code in C++ (or other relevant languages) with an emphasis on performance and reliability.

Collaborate with cross-functional engineering teams to integrate protocol functionality into larger software systems.

Develop protocol parsers, encoders, and handlers compliant with DNP3 standards and specifications.

Work closely with QA and systems engineering teams to validate protocol behavior and ensure high system reliability.

Troubleshoot and resolve protocol-level issues in live or test environments.

Stay current on DNP3 standards and contribute to the refinement and evolution of in-house implementations.

Requirements

Solid experience implementing the DNP3 protocol at the source code level (not just using prebuilt libraries).

Proficiency in C++ with strong understanding of memory management, threading, and real-time system constraints.

In-depth knowledge of industrial communication protocols and SCADA architectures.

Strong problem-solving skills and the ability to debug and optimize protocol performance.

Local to Houston candidates are preferred. Remote candidates considered in the following locations: TX, FL, CO, LA, NM, Canada.

Do not apply unless you are authorized to work in the United States for any employer as client company cannot sponsor or transfer visas at this time.
