Senior Software Engineer- DO178

Leach International, a TransDigm Business Unit, is seeking a Sr. Software Engineer to join a small embedded software verification team supporting safety-critical aerospace power distribution and protection systems.Leach designs and manufactures high-reliability electrical power control and distribution components used in aerospace and defence applications where system performance and reliability are critical. These are engineered products used in flight-critical environments, requiring strict compliance, verification discipline, and certification rigor.This role focuses on embedded software verification within a DO-178C environment, working closely with design engineering, hardware engineering, and certification stakeholders to ensure software meets airworthiness and qualification requirements.The role is primarily software-focused, but sits at the intersection of software, hardware, and systems integration. You will gain exposure to embedded systems interacting directly with electrical hardware, including both low and high voltage environments. Candidates with strong software backgrounds will be trained on hardware testing and integration.What's in it for you as a Sr Software Engineer:Ownership of embedded software verification in a safety-critical aerospace environment. Direct exposure to DO-178C certification and airworthiness processesWork on niche, high-reliability aerospace power distribution and control systems used in flight-critical applicationsExposure to both software and hardware systems, with structured training provided for hardware testing and integrationHands-on experience with embedded systems interacting with real electrical hardware (low and high voltage environments)Career growth within Leach or other TransDigm business units, including Hartwell, Palomar, and other adjacent aerospace organisationsPrimary Responsibilities as a Sr Software Engineer:Develop and execute software verification plans in accordance with RTCA/DO-178C requirementsPerform verification testing of embedded software used in aerospace power distribution systemsDocument test execution results and produce formal verification deliverables, including Software Verification Reports (SVR)Collaborate with hardware, systems, and design engineering teams across the full development lifecycleBasic Qualifications of the Sr Software Engineer:Bachelor's Degree in Computer Science, Electrical Engineering, or related discipline5+ years of experience in embedded C software verification within aerospace or safety-critical environmentsExperience with Python for automation, testing, or verification supportStrong understanding of structured software development and verification processesThe OpportunityThis role is suited to a software engineer who wants to move beyond purely code-based delivery into a broader embedded systems and aerospace engineering environment.Leach operates in a niche segment of aerospace focused on high-reliability electrical power distribution and control systems, where engineering rigor, verification discipline, and certification compliance are central to product success.This creates an environment where software engineers gain exposure not only to embedded development and verification, but also to hardware integration and systems-level behaviour in real aerospace applications.The role provides breadth across software, hardware, and certification activities, making it well suited to engineers looking to develop into systems engineering, verification leadership, or broader technical roles within a highly regulated aerospace environment.If you would like to have a confidential chat, please contact Rabeel Imrane; Rabeel.imrane@rps-recruitment.com, +1 626 630 8659.
