Security Clearance * Candidates must be willing and able to obtain, and maintain, DV security clearance ## Description The Ultra Engineering function manages a portfolio of specialist capabilities, generating highly differentiated solutions and products by applying, systematically, electronic, mechanical, and software technologies in demanding and critical environments to meet customer needs. Within the Engineering function the Systems Engineering discipline ensures a defined multi/inter-discipline approach and assures the cross-discipline solution/products support a compliant system, offering a means to gain stakeholder acceptance. The Principal Systems Lead role is responsible for, and assures, a hierarchical implementation of the ISO 15288 processes and practices across the Systems Engineering life cycle, for the assigned project. This Lead role owns the solution in response to the collective technical requirements; furthering the clarity of the requirements for engagement and flow down to the other disciplines; managing the delivery of the required deliverables associated to the candidate solution/capability, whilst also assuring the evidence-base offers a managed approach to progressive acceptance. As a professional at this grade, they need to be able to apply their technical and leadership knowledge, making independent judgements based on reasoned decision making and significant previous experience. Often seen as a referral point or more senior team member, to escalate more complex challenges and opportunities to both the project and Systems discipline. This role is expected to act independently with minimal guidance and may mentor project managers/other discipline engineers/early careers., * Represents the Systems discipline as the lead Systems Engineer assigned to a project, owning the totality of the Systems assigned work packages and tasking, to deliver obligations and commitments to the enabling technical requirements, agreed processes, plans, quality, schedule and budget. * Supports the Engineering Project Lead (EPL) in delivering the delegated engineering management obligations, defines the team resources needed and delegates leadership and technical responsibilities applicable to the Systems work packages and assurance tasks to the allocated systems team. * Is responsible for all aspects of the development of technical solutions to large and complex engineering problems, demonstrate alignment to Systems Engineering practices, principles and processes, to ensure customer requirements are satisfied. * Quantifies and implements a marriage of technical processes and technical management processes to achieve the desired solution, delivering Systems Engineering artefacts, as required, across the engineering development lifecycle, to result in a positive project outcome. * Provide technical direction and exert technical influence across the numerous project work packages, such that the optimal approach, applicable processes, risk mitigations, architecture, design, and implementation are selected/identified. * Work closely with the system, hardware, firmware and software architects and design authorities to ensure consistency, design for modularity and re-use, and technical excellence. * Plans and delivers design reviews, to senior management and customers, to a level of clarity and quality to ensure a successful event/outcome. * Leads, manages and reports Systems aspects of the project to achieve optimal balance between requirements, solution maturity, technical risk, schedule and cost. * Manage customers and external suppliers to define and achieve expectations and objectives, where the System lead achieves acceptance via the technical solution and related products/artefacts. * Having delivered the solution acts as the Design Authority (DA), supporting the in-service phase and future opportunities/change. * Ensure and review technical/task proposals, providing accurate estimates for the associated effort, costs and risks, for bids and proposals, leading to contract award. * Technically lead other project discipline lead/s, working with project management and engineering project leads, to create proposals associated to the technical solution, that drive down project costs, risk and increase margin. * Reviews and signs off significant technical documents; frequently supporting the technical review chair with the significant deliverables. * Manage security of information as defined in the Security manual to ensure compliance with Government regulations. * Actively supports and offers value add improvements to the Systems discipline to grow the overall capability as a whole. * As required supports recruitment, early careers development and STEM engagement. * Leads others, in Systems and outside, to develop greater awareness and implementation of a systems approach, practices and applicable processes. * Line Management duties, proactively leading and coaching reports, aid the creation of development plans and support execution, whilst measuring continuous improvement in others. ## Related Videos - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Navigating the AI Revolution in Software Development](https://www.wearedevelopers.com/videos/1266-navigating-the-ai-revolution-in-software-development) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [When Agents Meet Legacy: Never Change a Running System](https://www.wearedevelopers.com/videos/100320-when-agents-meet-legacy-never-change-a-running-system) - [Breaking the Hardware Mindset: Overcoming Barriers to System-Level Innovation](https://www.wearedevelopers.com/videos/1635-breaking-the-hardware-mindset-overcoming-barriers-to-system-level-innovation) ## Related Articles - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Is Software Engineering Hard?](https://www.wearedevelopers.com/magazine/448-is-software-engineering-hard) - [The Ultimate Software Engineer Career Path Guide for 2023](https://www.wearedevelopers.com/magazine/146-the-ultimate-software-engineer-career-path-guide-for-2023) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering)
