Embedded Linux Software Engineer C/C - OMNTEC Mfg., Inc.

Software Engineer / Senior Software Engineer Linux Systems, ATG Connectivity & Data Full-time | On-site | Ronkonkoma, New York Own the data path from field hardware to the cloud — C/C++ on embedded Linux, with hardware and software all built in-house. Role Overview OMNTEC is seeking a mid-to-senior-level software engineer to join our team that develops our Proteus automatic tank gauge (ATG) products and the systems that integrate these products with our TankActive cloud platform. This role focuses on embedded Linux applications, ATG and field-device connectivity, data acquisition and transformation, and the database layer that houses/organizes field data. You will own the architecture and hands-on implementation of the controller-to-database data path, balancing reliability, performance, maintainability, and backward compatibility. This includes designing high-performance Linux services, implementing reliable communications, parsing and validating device data, and ensuring that inventory, alarm, sensor, and diagnostic information reach TankActive accurately. What You Will Do Design, develop, and maintain C/C++ applications and services on OMNTEC’s Linux-based PROTEUS controller. Build and support connectivity and data acquisition between PROTEUS, third-party ATGs, gateways, polling systems, and TankActive. Implement and troubleshoot TCP/IP, UDP/IP, and serial communications, including message framing, parsing, timeouts, retries, and recovery. Design and maintain PostgreSQL database schemas, queries, stored functions, and access code for reliable operational-data ingestion and retrieval, protecting data quality through validation, deduplication, timestamp handling, and replay/backfill. Collaborate with TankActive application engineers on data contracts and service boundaries (the web application itself is owned by another team). Diagnose issues in deployed field systems across hardware, OS, network, protocol, and database boundaries; create tests, diagnostic tools, documentation, and operational scripts; participate in code review and release validation. Core Requirements Strong C/C++ development experience on Linux, including debugging, performance analysis, and resource management. At least three years of professional software engineering experience, with demonstrated ownership of production systems. Solid relational database experience (PostgreSQL or comparable): schema design, complex SQL, and application access patterns. Able to work on-site in Ronkonkoma, NY. Preferred Qualifications Bachelor’s degree in computer science, engineering, or a related field, or equivalent practical experience. Thorough knowledge of Linux IPC (shared memory, message queues, semaphores, etc.), multithreading, synchronization, and data-concurrency management. #J-18808-Ljbffr Polluxa, Inc.
