The Role

Want to help shape how AI is built and scaled at Sonnedix?

As Senior Platform Engineer, you’ll implement and own the shared platform on which Sonnedix’s AI solutions are built, deployed and run. You’ll take the agreed platform design into production and make sure AI solutions can connect safely with our systems of record and other core systems.

This is a hands-on role with accountability for the platform’s reliability, security and day-to-day evolution. You’ll establish release standards, permissions, observability, evaluation and shared retrieval services, while working closely with the AI team, delivery partners, DevOps, Cyber and Architecture to make solutions safe and straightforward to build and operate.

Desirable skills:

• Extensive experience building and running production platforms that other teams depend on, using a modern technology stack such as Python, TypeScript, PostgreSQL and Kubernetes.
• Strong experience across security, identity, automated testing, CI/CD and observability, with a clear focus on reliability and secure development.
• A track record of building and maintaining platforms pragmatically, with the ability to explain technical and risk trade-offs clearly to both technical and business stakeholders.

AI & Digital Literacy

• Experience running large language model or agent workloads in production, or strong evidence of being able to develop this capability quickly.
• Understanding of AI evaluation, retrieval, model and prompt regression and agent observability, with good judgement around when AI or conventional software is the right solution.

We use English as our business language, please submit your CV in English.

We deploy AI across the business, from generation and trading decisions to the everyday workflows of every team. We invest in our people’s digital fluency so everyone works alongside these tools with confidence.
