As a Senior Software Engineer in our Digital Twins Division, you’ll help build the systems behind one of the company’s most ambitious AI products. Your work will enable thousands of AI‑driven “digital twins” to simulate real‑world consumer behaviour in real time, giving brands powerful insight into complex decisions.
This isn’t a traditional full‑stack role. You’ll focus on scalable backend systems, event‑driven architectures, and AI‑enabled platforms, working closely with product, data science and platform teams to turn advanced AI capabilities into reliable, production‑ready systems. Your work will directly shape how clients interact with data and insights at scale.
What you’ll be doing:
- Creating scalable, distributed backend services for AI‑driven applications
- Building event‑driven systems that process large volumes of behavioural data in real time
- Developing services in Node.js/TypeScript and/or Python
- Designing APIs that support high‑throughput, low‑latency workloads
- Helping orchestrate and optimise AI agent‑based systems running at scale
You’ll also contribute to technical direction, mentor others, and help us continuously improve how we build and operate our platforms.
The skills & experience you’ll bring:
- Strong backend engineering experience with cloud‑based systems (Azure, AWS or GCP)
- Experience designing distributed or event‑driven architectures (Kafka or similar)
- Proficiency in TypeScript/Node.js and/or Python
- Experience building scalable APIs and microservices
- Working knowledge of containers and cloud‑native delivery approaches
- Curiosity about AI‑enabled systems and how they scale responsibly
- Experience with LLMs, AI agent orchestration, or tools such as RAG, vector databases or LangChain is a bonus, but not essential.
What’s in it for you:
- Flexible hybrid working
- 25 days leave, 2 days paid for volunteering and life event leave
- Competitive salary and bonus (bonus dependent on role)
- Company pension
- Enhanced parental leave
- Healthcare options
- Wide range of flexible benefits
