Senior AI Engineer

Salary: £65,000 - 105,000 per year

Requirements:

• 4+ years of software engineering experience, ideally including exposure to AI-enabled or data-intensive systems.
• BS in Engineering, Computer Science, or equivalent.
• Comfortable working autonomously within a defined problem, questioning unclear assumptions, and delivering in short, time-boxed cycles focused on validated outcomes.
• Experience building RAG pipelines, tool-augmented agents, and agentic workflows; familiarity with prompt engineering, context management, evaluation, and observability.
• Understanding of how agents use memory, tools, and retrieval to complete multi-step tasks.
• Ability to design across multiple components and translate product requirements into workable software designs.
• Ability to write and review portions of detailed specifications for complex system components.
• Experience integrating AI into existing systems through APIs and data pipelines.
• Experience with AWS, Azure, or GCP.
• Experience with CI/CD, modern SDLC practices, TDD, and code review.
• Experience working with relational, columnar, and vector stores, with sound data-modelling principles.
• Proficiency in Python, Java, TypeScript/JavaScript, SQL, and relevant AI SDKs.
• Developing mentoring skills through pair programming and day-to-day collaboration.
• Clear written and verbal communication with technical peers and stakeholders.
• Ability to instrument solutions and capture usage, productivity, and quality metrics against established baselines.

Responsibilities:

• Build prototypes and proofs of concept, and deliver agentic AI solutions to production standard within a defined technical approach.
• Implement and test tool use, retrieval pipelines, and agent workflows.
• Contribute to evaluation, observability, and guardrails for agentic systems, identifying operational requirements for logging, instrumentation, and alerting.
• Instrument solutions to capture outcome data against established baselines.
• Integrate AI capabilities into existing enterprise workflows and systems.
• Work with technical peers and team members to finalise requirements and write and review portions of detailed specifications for complex system components.
• Translate product requirements into software designs, collaborating with host-function stakeholders to ensure solutions fit real workflows.
• Complete moderately complex bug fixes and flag technical risks and blockers early.
• Implement continuous integration, delivery, and deployment practices, applying coding best practices and participating in code reviews.
• Maintain code quality and documentation, and develop reusable solutions, patterns, reference implementations, and starter kits.
• Collaborate with stakeholders across development environments, including Agile and Waterfall.
• Pair-program with squad members and support handover and capability-building so host functions can own and operate solutions after the squad moves on.
• Develop mentoring skills and support less senior engineers in development methodologies and optimisation techniques.
• Keep up with new technology developments and take on related responsibilities as the squads needs evolve.
