AI Solutions Architect

GBP 70000-100000 / yearMidHybrid

We're building the UK's next generation engineering powerhouse, providing critical technology that strengthens national security and resilience. We specialise in turning advances in sensing, AI, and communications into

Skills

We are looking for someone with solid AI and ML engineering foundations who is ready to start applying that knowledge at a higher level. We value potential and appetite as much as prior experience in architecture. Essential - Hands-on experience as an AI or ML engineer. You have built, trained, and deployed models and understand what makes AI systems work in practice. - Working knowledge of at least one of: agentic AI and LLM application patterns, ML model serving and monitoring, data pipeline design, or MLOps practices. - Ability to think beyond implementation. You can ask “why are we building this?” and “how does this fit into the wider system?” as well as “how do we build it?”. - Clear written and verbal communication. You can explain technical concepts to people who aren’t deeply in the weeds. - Curiosity and a willingness to develop in areas outside your current specialism. - Awareness of AI security and safety principles (e.g. secure data handling, access control, model risk), and a willingness to build this further given Rowden’s defence and national security context. - Eligibility for SC clearance. Desirable (not essential) - Exposure to data platform patterns such as medallion or lakehouse architectures. - Hands-on experience with MLOps tooling or model-serving infrastructure used to operationalise and scale ML systems. - Any experience contributing to technical documentation, proposals, or solution designs, even informally. - Familiarity with edge deployment constraints or resource-limited inference environments. - Experience in secure, regulated, or government-adjacent environments. About you - You are technically grounded but starting to think beyond the code. You want to understand the full shape of a solution, not just your part of it. - You communicate clearly and are comfortable articulating ideas to people at different levels. - You are curious and self-directed. You don’t wait to be told what to learn next. - You are humble about what you don’t know, and you actively seek to close those gaps. - You want a role where you are developed, not just deployed. - You are ready to engage with customers and stakeholders, even if that’s new territory, and you see it as an opportunity.
