Recruiter for this role: Britney Dias

Key Responsibilities

- AI Feature Design &
- Delivery - Design, build and run AI powered features using large language models, translating product ideas into reliable, scalable production systems that deliver measurable impact.

- LLM Integration &

- System Architecture - Integrate LLMs into existing applications and services, shaping backend architectures and APIs that balance performance, cost, security and maintainability.

- Prompt Engineering &

- Model Optimisation - Develop, test and refine prompt strategies to improve model accuracy, safety, latency and cost efficiency across different use cases.

- Hands-On Engineering - Build and maintain backend services and APIs using TypeScript and contemporary frameworks, contributing clean, well documented and maintainable code aligned with engineering best practice.

- Cross-Functional Collaboration - Work closely with product, data and design partners to identify high value AI opportunities and shape solutions that are feasible, testable and aligned to user needs.

- Evaluation &

- Monitoring - Define and implement evaluation approaches for LLM based systems, including logging, metrics and experimentation, to continuously improve quality and reliability in production.

- Scalable AI Patterns - Contribute to shared approaches, architectural patterns and standards for building AI driven features across the platform.

- Risk, Privacy &

- Cost Awareness - Make informed engineering decisions that consider data privacy, model risk, operational resilience and commercial constraints.

- Continuous Learning &

- Innovation - Stay current with emerging AI technologies, tools and techniques, proactively recommending improvements that enhance outcomes for users and teams.

Knowledge, skills and experience required

- Our tech stack includes TypeScript (Node.js and React), AWS, Kubernetes, DataDog, GraphQL, PostgreSQL, Mongo, and Kafka.

- A strong foundation in software engineering, with hands-on experience building, shipping and operating scalable,



production-grade systems.

- Proven experience working with modern JavaScript and TypeScript stacks, including Node.js and associated backend frameworks, and confidence contributing to clean, maintainable codebases.

- Practical experience integrating large language models into real applications, using APIs such as OpenAI, Anthropic or similar, with an understanding of prompt design, evaluation and operational trade-offs.

- Confidence designing and working with APIs and backend services, including RESTful architectures and integration patterns that support reliability and scale.

- Familiarity with cloud-native environments and production tooling, including containerisation, monitoring and deployment practices, ideally within AWS-based ecosystems.

- Experience working with data stores such as PostgreSQL, MongoDB and or vector databases, with an understanding of how data design supports AI driven use cases.

- The ability to reason about cost, latency, privacy and risk when designing AI powered systems, and to make pragmatic engineering decisions within real-world constraints.

- Strong problem solving skills and attention to detail, with a mindset oriented toward iteration, evidence and continuous improvement.

- The ability to communicate complex technical concepts clearly and simply to a range of audiences, from engineers to product partners and non-technical stakeholders.

- Curiosity and adaptability, with a genuine interest in staying current with emerging AI tools, techniques and best practices, and applying them thoughtfully rather than reactively.

- A collaborative approach and empathy for users and teammates, contributing positively to a team environment and shared ownership of outcomes.

- We encourage applications from people who want to grow into this role and welcome those who bring diverse perspectives, career paths, and experiences.
