Senior Embedded Software Sustaining Engineer required for a manufacturer of life saving electronic solutions products. Part of a global group, this company offersrewarding careers, great benefits, and plenty of opportunities to grow in a supportive, energetic workplace. Hybrid working options (5 out of 10 days in the Rochester office).
We are seeking a dedicated Software Engineer to take ownership of sustaining and enhancing existing embedded firmware and software product portfolio, primarily developed in C, with some C++ used for QT-based front ends.
This is a new role within the R&D team, created to ensure the continuity and quality of support for mature products. The primary focus will be maintaining and improving current products through bug fixes, minor enhancements, and new device driver integration, allowing the core development team to focus on new product innovation.You will become a key knowledge holder across the product range and work closely with the software manager to plan and coordinate sustaining engineering tasks. While they operate a rotating schedule where software engineers take turns supporting legacy products, this role will act as the lead for sustaining efforts - identifying support needs and requesting assistance from the broader team when specific expertise is required.Youll be joining a collaborative and multi-disciplinary team that spans software, electronics, mechanical design, and testing. The role offers both independent responsibility and the chance to collaborate across functions to ensure our existing products continue to meet the highest standards.This position comes with a steep learning curve, as it requires gaining in-depth knowledge of multiple product lines and the ability to switch contexts effectively. Strong planning, system design, and documentation skills are essential, along with a proactive approach to problem-solving and coordination.
