Ready to play your part?

At AWE, it's not just a job, it's far more than that. Our shared purpose is to help keep the nation safe. Could this role be the opportunity for you to play your part?

As a Senior AI‑Assisted Software Engineer, you will take technical ownership of delivering secure, high‑quality software solutions using advanced AI‑enabled development techniques. Working within AWE's AI Capability Development team, you'll translate business requirements into robust applications, accelerate coding and testing through AI tools, and shape solution designs alongside the AI Platform Specialist and other engineers.

By combining strong engineering fundamentals with modern AI‑driven practices, you'll help AWE deliver new capabilities at pace while supporting the AI Factory mission and mentoring junior developers in AI‑assisted development.

Key Accountabilities

• Accountable for delivering robust software solutions that meet requirements and user needs, from design through release. Ensures projects are completed on schedule and to a high standard, using AI-assisted tools to speed up delivery without sacrificing quality.
• Accountable for the technical soundness and quality of software outputs. This means enforcing best practices in coding, testing, and documentation, and embedding automated quality checks (e.g. code analysis, security scanning, test coverage) in pipelines. Ensures delivered software is secure, scalable, and aligned with AWE's architecture and compliance standards.
• Help improve AWE's development capability by piloting and integrating new AI-assisted engineering tools and methodologies. Working with the team and the AI Capability Development lead, keep the team at the forefront of software engineering trends - trialling new code-generation tools, testing frameworks, or coding patterns - to increase productivity and future-proof AWE's internal engineering.
• Act as a mentor and technical coach to junior developers, guiding them in code craftsmanship, problem solving, and effective use of AI development tools. Accountable for raising the team's skill level and confidence with AI-augmented workflows, fostering continuous learning and improvement.
• Work closely with cross-functional stakeholders (AI Adoption teams, data engineers, and IT infrastructure) to ensure software is well integrated into the broader AI ecosystem and existing systems. Liaise with these groups to align on requirements, ensure compatibility with enterprise architecture, and guarantee smooth deployment and handover into operational use.
• Ensure all development activities and outputs align with AWE's safety, security, and Responsible AI guidelines. This includes upholding data protection and ethical AI use in any code or models and swiftly addressing risk or compliance issues. Foster a development environment where governance is an enabler, baked into everyday practices (e.g. approved libraries, documenting model usage).
• Drive a results-oriented approach, ensuring delivered software demonstrably contributes to efficiency, automation, or other mission goals. Accountable for meeting or exceeding performance benchmarks - e.g. improvements in development cycle times, system performance, or user satisfaction - through effective use of AI-enabled methods.

Who are we looking for?

We do need you to have the following:

• Bachelor's degree (or equivalent experience) in Computer Science, Software Engineering, or a closely related field. An equivalent combination of education and substantial professional software development experience will be considered.
• Proven experience in software engineering, typically in the range of 3-5+ years.
• Track record of using modern development practices and tools
• Strong software development skills

Whilst not to be considered a tick list, we'd like you to have experience in some of the following:

• Experience acting in a technical lead or senior developer role on a project or product team.
• Industry context experience in a highly regulated or secure sector (defence, aerospace, government, etc.).
• Cutting-edge AI/ML knowledge.
• Cloud & architecture certifications: Formal certifications such as Microsoft Azure Developer or AWS Certified Developer, or training in software architecture, indicating a solid grounding in designing scalable, cloud-based solutions.
• Project management or Agile certifications (Scrum Master, PRINCE2 Agile, etc.), suggesting the ability to blend technical and organizational skills to coordinate complex development efforts.

Work hard, be rewarded:

We ask a lot and set the bar high because our work truly matters. In return we offer balance, with award winning benefits including:
