Software Developer

Key Responsibilities

• Port the polling engine and existing protocol drivers from Windows to Linux.
• Resolve platform differences, including serial and socket APIs, threading, timers, data type sizes, struct packing, and byte order.
• Implement and maintain protocol drivers in C++, including request scheduling, framing, parsing, and error recovery.
• Handle field communication conditions, including serial and TCP transports, slow and lossy links, device quirks, and vendor-specific protocol variants.
• Verify ported drivers against the Windows originals by polling the same devices and comparing real-time data, history, events, and alarms.
• Test against physical RTUs, flow computers, and PLCs on a test bench, and against device simulators.
• Build automated regression tests that compare Linux and Windows driver output.
• Build diagnostics for communication health, including link status, retry behavior, throughput, and per-device statistics.
• Diagnose communication failures using serial and network captures and protocol analyzers.
• Document protocol behavior, device-specific quirks, and test coverage for each driver.
• Work with other product teams on shared components and cross-product integration.
• Participate in team sprint ceremonies and own drivers from refinement through production.

Requirements & Tech Stack

• Languages: C++ (Windows and Linux)
• Delivery: Docker containers, traditional Windows and Linux installers
• Tooling: Azure Pipelines (CI/CD), JFrog Artifactory, Atlassian suite (Bitbucket, Jira, Confluence)

Qualifications

• Bachelor’s degree in Computer Science, Engineering or a related field, or equivalent practical experience.
• Experience developing in C++.
• Experience configuring, polling or troubleshooting RTUs, flow computers or PLCs.
• Experience implementing or integrating industrial protocols such as Modbus, ROC, DNP3, OPC UA or vendor-specific protocols.
• Understanding of binary data handling, including framing, byte order, checksums/CRCs and timing-sensitive request/response cycles.
• Experience with serial (RS-232/485) and TCP/IP device communication.
• Comfortable developing and debugging on Linux.
• Strong attention to detail and clear written communication of test results.

Experience porting code between Windows and Linux is a plus.

Experience with containerized deployment (Docker) is a plus.

Understanding of electronic flow measurement (EFM) data is a plus.

Background in oil and gas field operations, or as a measurement technician, automation technician or SCADA engineer, is a plus.
